1 Introduction

2 Basic concepts

2.1 Processors & Chains

The fundamental building block of zynthian's sound architecture is the processor. A processor generates or manipulates audio or MIDI signals. Zynthian includes over 1000 processors to choose from.

Processors are grouped together and interconnected within chains. Chains are a key concept in Zynthian. The first thing you will do after powering-on your zynthian for first time, once you stop celebrating your success, is creating a chain and adding some processors. It does little without any chains!

Processors may be positioned within the chain in series or in parallel with other processors. The quantity of series or parallel processors is only limited by available processing power. Audio signals coming out from chains feed a stereo mixer with typical mixer strip controls: fader, balance, mute, solo, phase reverse, etc. Audio processors may be positioned pre-fader or post-fader.

The audio and MIDI signals are routed between physical inputs, chain inputs, chain outputs, physical outputs and processor sidechain inputs. This provides a lot of flexibility whilst maintaining a simple, chain-based approach to signal routing.

An example of a chain

2.1.1 Type of chains

When you create a chain, you must choose a type for it:

  • Synth Chain => Receives MIDI note-events and generates audio output. It must have a synth processor.
  • Audio Chain => Receives audio-input and generates audio-output. It only has audio-FX processors.
  • MIDI Chain => Receives MIDI-input and generates MIDI-output. It only has MIDI processors.
  • MIDI + Audio Chain => Receives MIDI + Audio input and generates MIDI + Audio output. It has MIDI and audio-FX processors.
  • Generator Chain => Generates audio output using an algorithm. The first processor is an audio generator.
  • Special Chain => It can contains special processors, a MOD-UI pedalboard or a Pure Data patch. It can process audio and MIDI.


The chain's type can't be changed after creating the chain. Processors can be added, removed and positioned within the chain.

Synth and MIDI chains have a MIDI channel assigned. MIDI channels are not exclusive, so you can assign the same MIDI channel to several chains.

In MIDI+Audio chains, all audio processors in the chain receive all the MIDI events in the assigned channel. This is very convenient for some processors, like vocoder and auto-tune ones.

MIDI chains can be configured to receive all MIDI channels. This is specially useful when using zynthian as a MIDI router.


2.1.2 Type of processors

There are five fundamental types of processor

  • Synth => Receives MIDI events and generates audio output.
  • MIDI => Receives MIDI events and generates MIDI output.
  • Audio => Receives audio input and generates audio output.
  • Generator => Generates audio output and has no input.
  • Special => Recieves MIDI events and audio input and generates MIDI output and audio output.

Each type of processor is catagorised to ease user selection, e.g. Synths have categories: Synth, Sampler, Piano, Organ, Acoustic & Percussion.

Each processor has parameters that may be controlled with zynthian knobs or mapped to MIDI CC messages. Processors may have presets that may be arranged in banks.

2.2 MIDI input

Chains receive MIDI data from a set of MIDI inputs. These MIDI inputs could be external MIDI devices connected to MIDI DIN-5 or USB MIDI (sequencers, keyboards and other MIDI controllers) or other MIDI sources (MIDI network services, etc.) and they can be configured for each chain separately. Each MIDI input can work in 2 different modes:

2.2.1 Active mode

When an MIDI input is configured in active mode, the active chain (the highlighted or selected chain) receives all MIDI input from it and all MIDI events are translated to the active chain's MIDI channel. This is the default mode for all MIDI inputs. When using active mode you don't need to worry about the MIDI channel your keyboard or controller is using. You change which instruments are played by changing the active chain in your zynthian (see below).

Active mode's behavior can be modified by the Active MIDI channel global flag (see admin menu):

  • Active MIDI channel Disabled => Only the active chain receives data from the MIDI input in active mode. This is the default setting.
  • Active MIDI channel Enabled => All chains with the same MIDI channel as the active chain receive data from the MIDI input in active mode. This is very useful for layering sounds without any extra routing. You simply create several synth chains with the same MIDI channel and they will play in unison. You can also create keyboard splits by adjusting note range and transpose for each chain.

2.2.2 Multitimbral mode

When a MIDI input is configured in multitimbral mode, only those chains matching the input's MIDI channel will receive data from this MIDI input. No MIDI channel translation is performed. Multitimbral mode allows receiving and managing each MIDI channel individually. Each MIDI input selects the chains it drives using the MIDI channel. If you are using an external sequencer or a MIDI controller that can sequence multiple tracks (Beatstep Pro, Keystep Pro, Novation Circuit, etc.), you may want to use multitimbral mode.

MIDI input mode diagram


Note:

Note that MIDI CC (Continuous Controllers) events are handled differently and they are not routed to chains. See section on MIDI Learning & binding.

2.3 Signal workflow

As introduced above, Zynthian's signal workflow is based around chains of audio & MIDI processors that feed an audio summing mixer and MIDI outputs. This diagram gives an overview of signal paths which may help in understanding the flow of audio and MIDI signals.

2.4 Snapshots

A snapshot is the captured state of zynthian at the time of saving the snapshot. Snapshots are saved in a JSON file with .zss extension and can be loaded at any time, which effectively restores the state of the zynthian device when the snapshot was saved. Snapshots include:

  • chains layout: configuration of each chain including its processors and how they are arranged and connected
  • audio levels: (optional) physical audio interface settings
  • sequencer: patterns & sequences
  • MIDI settings: global MIDI settings, USB MIDI port names, etc.!!
  • multitrack record settings: mixer strips armed for multitrack recording
  • UI state: some user interface configuration relevant to the snapshot (most UI is configured globally)
  • sub-snapshots (ZS3s): most other configuration (see ZS3)

Each time you overwrite an existing snapshot file, a backup copy is created. Backups can also be restored at any time, which can avoid much suffering. When you feel the panic, remember that zynthian stores the full save history for all snapshots!

Note:

Many zynthian users like to see snapshots as "zynthian project" files and it's not a a bad approach.

2.4.1 Last state snapshot

When zynthian starts, it always try to restore the last state saved as this snapshot. It always trys to save the current state before performing some operations, like:

  • power-off
  • restart
  • update
  • clean all
  • etc.

For convenience, the last state snapshot can also be saved or restored manually.

2.5 Sub-snapshots: ZS3

ZS3 means Zynthian Sub-SnapShot. A ZS3 is a partial state that is stored in memory and can be recalled very fast. ZS3s can be easily associated (learned) to MIDI Programs (program change events). Of course, all ZS3s are saved and restored with snapshots, including the default state of the snapshot when first loaded (ZS3-0).

ZS3s include:

  • chains configuration: for each chain, MIDI channel, note-range, transpose, etc.
  • processors state: for each processor, bank, preset & parameter values
  • mixer settings: for each mixer strip, fader, balance, mute, solo, etc.
  • MIDI devices configuration: active / multitimbral mode, etc.
  • MIDI & Audio routing: connections between chains
  • MIDI learning: MIDI bindings to processor and mixer parameters
  • global settings: some global settings that can be changed by ZS3, e.g. MIDI transpose (most global settings are not available to ZS3)
  • active chain: chain that was active when the ZS3 was saved

The key concept to understand how ZS3s work is noting that chains layout is not stored in ZS3s. In other words, chain's layout is not modified when retoring ZS3s. You can't add/remove chains or processors by restoring ZS3s because this is a slow operation and ZS3s need to be restored very fast.

When loading a snapshots that contains ZS3s, all the chains and processors are created. Later, when recalling the ZS3s, chain's layout will remain the same. Although ZS3s can modify routing, splits, banks, presets, etc., the quantity of chains and processors will be unchanged.

Note:

For instance, if you are keyboardist that plays with several bands, you could have a snapshot for each band with ZS3s for each song.


3 The physical interface

V4 render zenital mixer.jpg
Zynthian barebones.png

3.1 Description

The V5 physical user interface is composed of:

  • 4 infinite knobs (rotary encoders) with push switches
  • 5x4 silicone push button grid with RGB-LED feedback
  • 5 inch display with capacitive touch

The 20 silicone push buttons and the 4 knobs with switches are the primary user input mechanism to navigate the UI:

  • access the different views
  • select options on menus and lists
  • modify parameters

Each push button is engraved with a text legend or icon and backlit with RGB LED that gives status feedback. The knobs are numbered from top to bottom, so the top one is knob#1 and the bottom one is knob#4. We will refer knobs in this way throughout this guide.

The V4 physical user interface is composed of:

  • 4 infinite knobs (rotary encoders) with push switches
  • 4 silicone push buttons: These buttons doesn't exist in older V1-V3 kit versions.
  • 3,5 inch display with resistive touch

The four knobs with switches are the primary user input mechanism to navigate the UI:

  • access the different views
  • select options on menus and lists
  • modify parameters

The simplest user interface is composed of a display with touch or mouse. A minimum display size of 5 inches and capacitive touch is strongly advised when this is the primary user input method. Zynthian UI can also be run head-less, accessing remotely with VNC.

3.2 User interaction

Users interact with the system by pushing the silicone buttons or knob-switches or rotating the knobs. Touch can be used too for most operations and some interactions are only available from the touch interface, like the X-Y control ala kaos pad. Users interact with the system by touching/clicking the display elements and performing touch/mouse gestures, like drag, horizontal or vertical swipes, pinch-zoom, etc. User actions normally produce some feedback in the display. Also, the RBG LEDs give feedback and status info.

3.3 Types of action

User actions can be divided in 3 groups:

  • Push: You can push buttons, knob-switches or display widgets. There are 3 types of push actions, depending on how long you hold down before releasing.
  • Knob rotation: You can rotate knobs, of course ;-)
  • Touch gestures with display's touch surface or mouse: Drag, swipe, pitch-zoom, 2-fingers drag, etc.

These icons are used throughout this guide to indicate UI actions :

UI actions
Ui push short icon.png Short Push Push and release in less than 0.3 seconds.
Ui push bold icon.png Bold Push Push and hold for longer than 0.3 seconds then release before 2 seconds.
Ui push long icon.png Long Push Push and hold for longer than 2 seconds. Long-action triggers before release.
Ui knob rotate icon.png Knob Rotate Rotate the knob.

You can change the timings from the webconf's UI options tab. Not all buttons have actions assigned to all three push types. You can modify the assigned actions from the webconf tool, accessing the advanced options in the wiring layout section.


3.4 Using the knobs

V5 render knobs numbered.jpg

The V5 knobs behave quite differently to V1-V4 knobs. Because of the 20 silicone buttons, there is no need to use the knobs' switches to navigate the UI which now is best achieved with the push buttons, so when appropriate, knobs' switches have been mapped to drive the MIDI learning functionality, which is quite intuitive. The knobs are numbered from top to bottom, so the top one is knob#1 and the bottom one is knob#4. We will refer knobs in this way throughout this guide.

General rule

Although knob's behavior is contextual, there is a kind of pattern that can serve as a general rule and applies to many views:

  • Knob#4 is the select knob.
    • rotate to browse lists and move the cursor horizontally in grids.
    • short-push to select items, like the SEL button.
  • Knob#3
    • rotate to move the cursor vertically in grids.


Note:

MAIN Volume is always available with one click. Push MIX button and rotate Knob#3 to change the MAIN volume.

The V4 knobs (rotaries & switches) are the primary mechanism to navigate the UI. It's functionality is contextual, specially rotate, short and bold-push actions. Long push actions are always global. The knobs' names used in this guide are the names printed in the official V4 aluminum case, but you could find some section using the numbered notation, from top to bottom and left to right:

  • layer => knob#1
  • back => knob#2
  • learn/shot => knob#3
  • select => knob#4

General rule

Although knob's behavior is contextual, there is a kind of pattern that can serve as a general rule and applies to many views:

  • SELECT Knob
    • rotate to browse lists and move the cursor horizontally in grids.
    • short-push to select items.
  • BACK Knob
    • rotate to move the cursor vertically in grids.
    • short-push to back to previous view.

This general rule is extended in the next section.

Note:

MAIN Volume is always available with one click. Bold-push BACK Knob to open the mixer view, then rotate Learn/Shot Knob to change the MAIN volume.

3.5 Using the push buttons

The V5 push buttons grid is divided in 5 groups:

View buttons

V5 buttons outlined.png

View buttons are outlined on green in the image and they allow direct access to the main views. Most of these buttons have 2 different views assigned, with a horizontal line separating the 2 printed labels. The primary view is printed at top and the secondary view is printed at bottom. The "metronome" button is the exception, as it's the tap-tempo button. You push it once to access the tempo settings view, but you can tap-it several times to change the tempo BPM. Try it!

LED color depends on current view:

  • when the primary view is shown, the button lights green.
  • when the secondary view is shown, the button lights orange.
  • when none of the button's views are shown, the button lights blue.

A short-push on the button will access:

  • the primary view, when none of the button's views is shown
  • the secondary view, when button's primary view is shown

A bold-push on the button will always access the secondary view, not matter what the current view is.

For instance, if you are in the mixer view and short-push OPT/ADMIN, the Main menu will be opened. If you short-push it again, the Admin menu will be opened. Then, if you bold-push the MIX/LEVEL button, the Audio Levels view will be opened. You push "metronome" button and the Tempo settings view will be opened. If you tap-it several times, the tempo BPM will be changed, e.g. tap twice per second to set tempo to 120BPM.

View buttons are, from left to right and top to bottom:

V5 buttons outlined-3-detail2.png
  • OPT/ADMIN
    • Options / Menu: Contextual. Click several times to reach the main menu.
    • Admin menu
  • MIX/LEVEL
    • Mixer
    • Audio Levels
  • CTRL/PRESET
    • Chain Control
    • Preset/Bank
  • ZS3/SNAPSHOT
    • ZS3 (SubSnapShots)
    • Snapshots
  • METRONOME
    • Tempo settings / Tap-Tempo
  • PAD/STEP
    • ZynPad (Scene)
    • Pattern Editor

Some buttons have a tertiary function assigned to long-push:

  • OPT/ADMIN => Long-push to power off.
  • CTRL/PRESET => Long-push to enter/leave preset favorites
  • PAD/STEP => Long-push to access the Arranger view


ALT button

V5 buttons outlined-4.png

The ALT button toggles the alternate function mode. When you push it, the ALT button and the buttons having an alternate function will change their default color from blue to purple or orange. ALT mode is contextual, depending of the current view. By default, only transport and custom buttons (F1-F4) have alternate functions, defined like this:

  • Transport buttons toggle between Audio Player/Recorder (normal) and MIDI Player/Recorder (alternate).
  • Customizable F1-F4 buttons toggle between Program Change 1-4 (normal) and Program Change 5-8 (alternate). You could use it, for instance, to learn and recall up to 8 subsnapshots (ZS3s).

Some views have a custom ALT mode with specific functionality that overrides partial or totally the defaults:

Pattern Editor
Uses arrow buttons to quickly access undo/redo functions:

  • LEFT undo the last record operation
  • RIGHT redo the last record operation
  • UP undo ALL record operations
  • DOWN redo ALL record operations

When adding notes step by step, each note added/removed is a record operation. When live recording, recorded notes are grouped in pattern-loops.

Sooperlooper
Redefines the short-push functionality of transport, arrows and F1-F4 buttons:

  • REC
    • on empty loop: toggles recording in the selected loop
    • on busy loop: toggles overdubbing in the selected loop
  • PLAY toggles mute the selected loop
  • STOP toggles multiplying the selected loop
  • F1 toggles replacing in the selected loop
  • F2 toggles substituting in the selected loop
  • F3 toggles inserting in the selected loop
  • F4 adds a new empty loop
  • LEFT undo the last operation in the selected loop
  • RIGHT redo the last operation in the selected loop
  • UP/DOWN changes the selected loop


Transport buttons

V5 buttons outlined-3-detail.png

By default, transport buttons control the global audio recorder/player and default color is blue. When "ALT" button is pushed (ALT mode enabled), transport buttons control the MIDI recorder/player and default color is purple.

  • short-push REC (solid circle) to start/stop a recording. When a recording is in progress, the record button lights red and you should also see the rec icon in the display status area, at top-right.
  • short-push PLAY (solid triangle) to play/pause the currently selected track. The last recorded track is selected by default. When a track is being played, the play button lights green. After pausing, pushing again will resume the playing in the point it was paused.
  • bold-push PLAY to open the track list. After selecting a track, the audio player control view will be shown.
  • short-push STOP (solid square) to stop playing a track and rewind. Pushing play again will start playing from the beginning.
  • bold-push STOP to stop all sounds, including any audio/midi track and sequences.

In some views/modes, transport buttons have specific (contextual) functionality. When this happens, they will light orange to help you to remember their normal behavior is altered. The views that have specific transport functionality are:

Pattern Editor
From pattern editor, transport buttons are used to control pattern recording/playing. Note that for recording a pattern, you may want to start playing before recording, so notes are captured live in the time grid. If not, notes are captured step by step.

Zynsampler
From the control view of any zynsampler processor, transport buttons are used to control the processor's recording/playing functions (instead of the global audio recorder/player).

Sooperlooper
The control view of the sooperlooper processor have a custom ALT mode that redefine the functionality of transport buttons and others. See above.


Navigation buttons

V5 buttons outlined-detail3.png

Navigation buttons are used for basic navigation and operation:

  • UP/DOWN:
    • Browse lists and menus.
    • Move cursor (selected item) vertically in pattern editor, zynpad, etc.
  • LEFT/RIGHT:
    • Select active chain in the mixer and chain-control views.
    • Move cursor (selected item) horizontally in pattern editor, zynpad, etc.
  • SEL/YES:
    • Select items in lists and menus.
    • Enter select mode in chain-control view for browsing controller pages.
    • Add/remove notes in pattern editor.
    • Play/Stop sequences in zynpad.
    • Answer "Yes" in confirmation dialogs.
  • BACK/NO:
    • Close current view, returning to previous view.
    • Answer "No" in confirmation dialogs.


Note:

When not in the control view, knob#4 acts as the select knob similar to the classic V1-V4 UI. Rotate to browse lists and move the cursor horizontally in grids (zynpad, pattern editor, etc.). Push to select items, same than SELECT button. Knob#3 can be used to move the cursor vertically in grids (zynpad, pattern editor, etc.).


Custom function buttons (F1-F4)
These buttons are considered to be customizable buttons, e.g. if you want direct access to other views, etc. you may reconfigure these buttons using the webconf's wiring layout tab.

As explained above, while describing the ALT-mode, these buttons are assigned by default to MIDI Program Change messages:

  • Normal mode: Program Change 1-4
  • ALT mode: Program Change 5-8

This default configuration is fine for learning/recalling subsnapshots (ZS3) and you may find this really useful if you use your zynthian as a keyboard expander.


Note:

Although all buttons and switches are fully configurable from the webconf tool (hardware->wiring->advanced), this guide refers to the official V5 profile configuration, that matches printed button legends. Of course, you are very welcome to experiment with button assignment and try different configurations. In fact, if you reach a sweet point, we may be able to produce an alternative keypad with custom printings. Simply contact us at the zynthian forum!


Ui action global v4.jpg

The zynthian's classic workflow (V1-V4) is based in the 4 knobs' switches. While short-push actions are generally contextual, bold and long-push actions are generally global.

Along the sections below, when omitted, these are the default push actions:

  • layer
    • bold-push to open the main menu.
    • long-push to open the admin menu.
  • back
    • short-push to back to the previous view.
    • bold-push to open the mixer view.
    • long-push to PANIC!. Stop all notes & sounds.
  • learn/shot
    • bold-push to open the ZS3 list.
    • long-push to open the snapshot list.
  • select
    • short-push to select/check/uncheck an item
    • bold-push to open contextual options.
    • long-push to power off the zynthian (it will ask to confirm).


The V4's extra buttons

The V4's extra silicone push buttons (S1-S4) can be configured depending of the user preference. This can be done from the webconf tool, accessing the advanced options in the wiring layout section. Some predefined customization profiles are available from there:

  • V4 Stage: The 4 silicone push buttons are assigned to MIDI program change 1-4. It's specially thought to use with ZS3.
    • S1 => MIDI Program 1
    • S2 => MIDI Program 2
    • S3 => MIDI Program 3
    • S4 => MIDI Program 4
  • V4 Studio: The 4 silicone push buttons are assigned like this:
    • S1
      • short => Audio Recorder/Player
      • bold => MIDI Recorder/Player
      • long => All Sounds Off
    • S2
      • short => Zynpad
      • bold => Pattern Editor
      • long => All Sounds Off
    • S3
      • short/bold => Arrow Up
      • long => All Sounds Off
    • S4
      • short/bold => Arrow Down
      • long => All Sounds Off
  • V4 CC Switches: The 4 silicone push buttons are assigned to MIDI CC 47-50. It's specially thought to MIDI learn toggle parameters (i.e. to use with SooperLooper)
    • S1 => CC 47 (value 0/127)
    • S2 => CC 48 (value 0/127)
    • S3 => CC 49 (value 0/127)
    • S4 => CC 50 (value 0/127)

4 The top-bar

4.1 The title-bar

Title Bar

The title bar acts as a kind of breadcrumb. It normally shows the view's title or current chain information: MIDI channel, engine, bank & preset.


4.2 The status area

Zynthian Status Bar.png

On the top-right corner, aside the title bar, is an area where some useful information is displayed in real time:

  • Digital Audio Peak Meter (DPM): horizontal bars indicating digital audio level and peaks
  • Status icons: indication of various zynthian states

4.2.1 The Digital Audio Peak Meter (DPM)

The DPM covers the range -50dBFS to 0dBFS, i.e. maximum permissible level at full scale (far right) down to 50dB below (far left):

  • The green segment covers the range -50dBFS to -10dBFS.
  • The yellow segment covers the range -10dBFS to -3dBFS.
  • The red segment covers the range -3dBFS to 0dBFS.

There are independent meters for left and right channels which monitor the system output, i.e. the mix of audio that feeds the Zynthian output. Level decays with a logarithmic rule, taking one second to decay to -200dBFS so will decay to -50dBFS (the displayed range) in about quarter of a second. Peaks are displayed instantly, i.e. the attack of the meter is immediate (*). The peak hold bar remains for two seconds or until a higher peak is reached.

This meter is the same as the main mixbus DPM that is always visible in the mixer view and is therefore hidden when the audio mixer view is shown.

(*) Meter is updated 5 times per second so there can be 200 ms delay in peak being displayed.

4.2.2 The status icons

1st row: Health & Load
Cpu Load Heart, indicating CPU load. It displays as green when under 50%, yellow when load is over 50% and red over 75%.
Software update available When a software update is available, the green recycle symbol is shown. You can update from the admin menu, webconf or terminal.
XRun It's shown when there are XRuns. This may be accompanied by clicks and pops on audio output. This means the CPU can't process or transfer audio fast enough and you should consider disabling some CPU-hungry option (like VNC, headphones, etc.) or reducing the complexity of your chains.
Under-voltage Zynthian is working in a degraded state, with the CPU frequency capped to 600-800 MHz, trying to stabilize the system and avoid a system crash. You shouldn't see that icon and if you do so, you should consider looking for a better power source.
Over-temperature Zynthian is working in a degraded state, with the CPU frequency capped to 600-800 MHz, trying to stabilize the system and avoid a system crash. You shouldn't see that icon and if you do so, you should improve heat dissipation (using a heat sink, etc.)
2nd row: MIDI activity & Playing/Recording
m MIDI-IN It's shown when MIDI messages are received. Underscore indicates system message such as MIDI clock.
Recording Audio Audio is being recorded.
Playing Audio Audio track is being played.
Recording MIDI MIDI is being recorded.
Playing MIDI MIDI track is being played.
Recording Pattern A sequencer's pattern is being recorded.
Playing Sequence A sequence or pattern is being played.

5 Basic Views

5.1 Mixer

Mixer legend.jpg

The mixer view is the most important view in zynthian. It's composed of vertical strips associated with chains. Initially it will be empty, showing the main strip alone. For each chain you create, a new strip is added to the mixer. (There can be more mixer strips than can be displayed. They will scroll left / right if you select a strip that is off screen.) Each strip is an interactive widget that can be manipulated in several ways and it shows status info about the associated chain. From top to bottom:

  • solo: Solo flag. Push to toggle. This is a non-exclusive solo mode. When a chain has solo enabled, all other chains without solo enabled will be muted, allowing auditioning of one or more chains. The **main** solo will disable all chain solos.
  • mute: Mute flag. Push to toggle. When a chain is muted (it has "mute" enabled), it will remain silent.
  • fader: Mixing volume for the associated chain. Drag up & down to modify the fader level. On the touchscreen you can drag multiple faders at once. Tap it to set the active chain.
  • description: A vertically oriented text describing the chain. By default, for a synth chain it will show synth processor and preset name. If you give a name to the chain, this will be included in the description too.
  • balance/pan: Mixing right/left balance (or pan of a mono signal) for the associated chain. It's controlled with the physical UI. See below.
  • legend: It shows an icon for the chain's type and a number for the assigned MIDI channel. Tap it to access the chain's control view.

5.2 Main menu

Chain menu legend.jpg
Main menu legend.jpg

The main menu is a selector view, consisting of a list of options you can browse and select. Most views in the zynthian-UI are of this type and they work in quite a similar way, with very little variation.

From this menu you can:

  • create a new chain
  • remove an existing chain
  • remove all chains
  • remove all sequences
  • remove all

In addition, the main and system sections allow accessing most of the main views and features:

  • Snapshots
  • Sequencer
  • Audio Recorder
  • MIDI Recorder
  • Tempo Settings
  • Audio Levels
  • Mixer Learn
  • Admin
  • Stopping All Sounds (PANIC!)

  • knob#4
    • rotate to move across options.
    • short-push or bold push to select the highlighted option.
  • UP/DOWN to move across options.
  • SEL to select the highlighted option.

5.3 Processor selector

Engines legend.jpg

The processor selector is a selector view, but a very special one.

5.3.1 Processor categories

To ease selection and avoid long lists, processors are classified in categories. The selector allows easy browsing across categories and processors so you can find what you want as fast as possible.

5.3.2 Extended info

In addition to the processor's name, when available, some extra info is shown for each processor:

  • Quality (stars): From 0 to 5, indicating how good is the processor. Of course, this is very subjective ;-)
  • Complexity (knobs): From 0 to 5, indicating how complex is the processor. It's usually related to the number of control parameters.
  • Description (text): A concise description of the processor's features.

5.3.3 Enable/Disable processors

To allow greater customization and avoid long lists of processors user never use, processors can be enable/disable. When a processor is disabled, it's not shown in the list, but still can be used when loading a snapshot that includes it.

5.4 Chain control

Control legend.jpg

The chain control view allow accessing the chain's processors and controlling their parameters. For instance, you can adjust the LFO frequency on a synth, the reverb's room size, the equalizer bands, etc. The default control view is composed of:

  • a list of controller pages, grouped by processor
  • 4 x controller widgets, dynamically assigned to the parameters of the selected page. The controller widgets are layered aside the 4 rotary encoders that can be used for modifying the parameter's value in real time.Depending of configuration options, the controller widgets could be layered at the four display corners (classic layout: top-left, down-left, top-right, down-right) or they could be all at right (V5 layout).

Controller pages can be browsed one-by-one or you can enter select mode to move faster across the list.


5.4.1 UI Actions

  • knob#1 - knob#4
    • rotate any knob to change the value of the assigned parameter.
    • short-push any knob to start MIDI-learning for the associated parameter. If wanted, a second push for global learning. Move a knob/fader in your MIDI controller to complete the learn. You can push BACK button to cancel at any moment.
    • bold-push any knob to open the options menu for the associated parameter.
  • UP/DOWN to navigate across controller pages.
  • LEFT/RIGHT to move across chains, changing the active chain.
  • SEL to enter select mode, then fast-browse controller pages by rotating knob#4.
