The Zynthian UI is displayed on a display and controlled by 4 knobs with switches. You can also control the UI with a touch-display, a mouse or a keyboard (computer keyboard or MIDI keyboard, both!)
The Zynthian UI is displayed on a touch display and controlled by 4 knobs (rotary-encoders with push-switches).
The 4 knobs+switches are the primary control mechanism to navigate the UI: selecting options on menus and adjusting the instrument parameters. The knobs can act as assignable MIDI/OSC controllers for the instrument's parameters (frequently lots of them!). You can emulate the knob's behaviour using the touch-display, but it's sub-optimal and accessing some features could be tricky.
[[File:Zynthian v4 top legend.png|600px|center]]
There are two main screen-layout types:
* '''Selector Screen''': a list of items that you can scroll and select with the SELECT knob (CTRL-4)
* '''Controller Screen''': 4 control widgets in the corners (one for each knob), with label and value indicators (graphic and numeric). In the middle there is a list of controller screens, each one mapping 4 controllers which you can use to change the engine parameters.
Most of Zynthian UI screens belongs to one of these 2 categories, however, other screen-layouts do exist:
* '''Confirmation Screen''': It will ask you to confirm some operation.
* '''Confirmation Screen''': It will ask you to confirm some operation.
* '''XY Controller Screen''': It allows to modify 2 parameters at once using the touch interface.
* '''XY Controller Screen''': It allows to modify 2 parameters at once using the touch interface.
* '''Info Screen''': It displays info about an operation, like "Update Software", or "Network Info"
* '''Info Screen''': It displays info about an operation, like "Update Software", or "Network Info".
* '''Sequencer''': It's a planned feature, not implemented yet ;-)
* '''Key Range & Transpose Screen''': It allows to choose the key range and transpose notes by octaves or semitones.
* etc.
There are 3 types of clicks (push-switch actions) that can be performed, depending on how long you hold down the knob (or hold your finger on the touch-display):
There are 3 types of push actions that can be performed, depending on how long you hold down the knob/button (or hold your finger on the touch-display).
* '''short click:''' less than 0.3 seconds
* '''Short push:''' Less than 0.3 seconds
* '''bold click:''' between 0.3 and 2 seconds
* '''Bold push:''' Between 0.3 and 2 seconds
* '''long click:''' more than 2 seconds
* '''Long push:''' More than 2 seconds (until the long-action is triggered!)
These timing values are the default ones. You can adjust them to your personal feeling from the webconf's UI options.
Some push actions depends of context. The SELECT knob is mainly used to navigate and a short push on it will select an item on a "Selector Screen". Inside a "Controller Screen", short pushes can be used to rotate between layers (LAYER knob) or between controller pages (SELECT knob). "Bold-pushes" are normally intended as shortcuts for jumping to specific screen like "layer options", "main menu", etc. Pushing the BACK knob generally close the current modal-screen or jumps to the previous screen in the workflow sequence.
Although some push actions depend of context (current screen), there are some actions that are global and will work from any screen:
* '''Bold-Back''': Main Menu
* '''Long-Layer''': Step Sequencer
* '''Long-Back''': Admin Menu
* '''Long-Learn''': Audio Levels
* '''Long-Select''': Power Off
Latest versions of zynthian kits include 4 extra push buttons, labelled as S1 to S4. By default, these buttons are assigned to MIDI Program Change 1-4, but this can be easily changed from the webconf's [[Configuration_Users_Guide#Wiring_Layout|Wiring Layout menu]].

=The Title Bar=
[[File:zynthian_ui_control_status.png|400px|right]]
The title bar have 2 functions:
* Audio Peak-meter or CPU-load => 1 or 2 small horizontal bars on the top right.
* Kind of Breadcrumb, normally showing the screen title or current layer information: MIDI channel, engine, bank & preset
* Back-button, when using the touch-interface. It's far from intuitive, but Zynthian-UI was not designed with touch-navigation in mind.
<br clear=all>
=The Status Area=
[[File:Status display.png|400px|right]]
On the top-right corner there is a small area where some useful information is displayed in real time:
* '''Audio peak-meter''' or '''CPU load-bar''' => 1 or 2 small horizontal bars on the top.
* '''Status Icons''' => Displayed under the peak-meter.

===The Peak-meter===
The blue M flag is shown when MIDI messages pass thru the MIDI router. Not all messages are detected. Only CC, Program Change and Note On/Off.
The Audio Peak-meter is shown by default. The meter covers the range -50dBFS to 0dBFS, i.e. maximum permissible level at full scale (far right) down to 50dB below (far left):
The red "warning" flag is shown when there are Xruns. You should hear clicks and pops too ;-)
* 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.
(*) Meter is updated 5 times per second so there can be 200 ms delay in peak being displayed.
Alternately, the "CPU-load" bar can be enabled from webconf, replacing the Audio Peak-meter. The CPU-load bar shows the CPU usage as calculated by the Jack Audio Server:
This is a running average of the time it takes to execute a full process cycle for all clients as a percentage of the real time available per cycle determined by the buffer size and sample rate.

=The UI Screens=
==Layer List==
==Main==
[[File:Zynthian_ui_main.png|400px|right]]
This is the first screen you would see when you power on your zynthian for first time and no default or last-state snapshot has been saved yet.
The Main menu gives easy access to the Zynthian-UI's main features:
* '''Layers'''
* '''Sequencer'''
* '''Audio Levels'''
* '''Audio Recorder'''
* '''MIDI Recorder'''
* '''Snapshots'''
* '''Clean All'''
* '''Admin'''
You always can access this menu with '''bold-back'''.
The Zynthian-UI has a lot of short-cuts and most of the options on the main menu can be accessed with them, but until you learn the shortcuts and feel comfortable with them, you will find this menu very useful.
<br clear=all>
==Layers==
Layers are a key concept on Zynthian-UI: the first thing you do after poweron your zynthian is, probably, create a layer.
A layer is a '''Processing Chain''', normally assigned to a MIDI channel, which can be composed of one or more Audio or MIDI Processing Units. These units are chained in the same order they are created, but you can change the order from the '''Layer Options''' menu. The first unit in a layer is the '''root''' and it determines the layer's type:
* '''Synth Layer''' => Receives MIDI note-events and generate audio output.
* '''Audio FX Layer''' => Receives audio-input and generates audio-output.
* '''MIDI FX Layer''' => Receives MIDI-input and generates MIDI-output.
* '''Generator Layer''' => Auto-generate audio output using an algorithm.
* '''Special Layer''' => MOD-UI pedalboard, Pure Data patch, etc.
The root layer can't be re-arranged or changed. When you create pure Audio-FX layers, it's a good idea to use a "Gain" unit as root element, so you can re-arrange/change all the other elements on the chain.
All units in a layer's chain receive all the MIDI events coming from the assigned channel. Some special layers (MOD-UI) don't have an assigned MIDI channel and receive all MIDI channels.
You can access the Layer screen:
* from any place, '''bold-layer'''
* from Main menu
[[File:Zynthian_ui_new_layer.png|400px|right]]
[[File:Zynthian_ui_new_layer.png|400px|right]]
There are several options on this screen:
There are several options on the layers screen:
* '''NEW Synth Layer''' => Create a new Synthesizer Layer.
* '''NEW Synth Layer''' => Create a Synthesizer Layer.
* '''NEW Effect Layer''' => Create a new Effect Layer that will be connected to soundcard's Audio Input.
* '''NEW Audio-FX Layer''' => Create an audio-FX Layer that will be connected to soundcard's Audio Capture. You can route the audio output from other layers to the input of an Audio-FX layer.
* '''NEW Generator Layer''' => Create a new Generator Layer that self-generates audio or midi.
* '''NEW MIDI-FX Layer''' => Create a MIDI-FX Layer to process MIDI events. You can route the MIDI output from a MIDI-FX layer to the MIDI input of any other unit or to the zynthian's MIDI output.
* '''NEW Special Layer''' => Create a new Special Layer that will receive all MIDI channels.
* '''NEW Generator Layer''' => Create a new Generator Layer that self-generates audio.
* '''REMOVE ALL''' => Remove all Layers (Root layers and its associated Effect-Chains), returning to the initial state.
* '''NEW Special Layer''' => Create a new Special Layer (MOD-UI, Pure Data, ...).
* '''PANIC! All Notes/Sounds Off''' => All notes and sounds are stopped abruptly by sending CC#123 and CC#120 to all channels.
* '''REMOVE ALL''' => Remove all Layers & Effects, returning to the initial state.
* '''PANIC! All Notes/Sounds Off''' => Stop All Notes and sounds by sending CC#123 and CC#120 to all channels.
The last option, ''All Notes/Sounds Off'', can be triggered by bold clicking CTRL-1 (layer) from the layer screen (contextual action). You can trigger this actions from any point in the workflow by simply bold-clicking twice CTRL-1. Also, you can add a ''panic-button'' to your zynthian using the extra pins from the AllInOne circuit. [[Adding Extra Switches|Read this for a detailed explanation about how to add a panic button to your Zynthian]].
The last option, ''All Notes/Sounds Off'', can be triggered with '''long-back''' from any point of the workflow. You can also add a ''panic-button'' to your zynthian using the extra pins from the AllInOne circuit or the Zynscreen.

When you select '''NEW Synth/Effect/Generator Layer''', you create a new root-layer (first of a chain), choosing a free MIDI channel for it. You can create up to 16 layers (as many as MIDI channels), each one having an independent effect-chain.
When you select '''NEW Synth/Effect/Generator/Special Layer''', you create a new root-layer (first of a chain), choosing a free MIDI channel for it. You can create up to 16 layers (as many as MIDI channels), each one having an independent effect-chain.
Having several layers in the same MIDI channel is not allowed. If you want two or more layers playing unison (like being in the same MIDI channel), you should use the "Clone" feature, that allows you to bind several layers while keeping MIDI CCs and other MIDI messages (Program Change, Channel Pressure, etc.) independent.

[[File:Zynthian_ui_admin_02.png|400px|right]]
MIDI-learning allows you to easily bind specific MIDI events with Zynthian-UI actions. There are 2 types of MIDI events you can learn:
====MIDI CC====
[[File:Zynthian_ui_midi_cc_learn_01.png|400px|right]]
[[File:Zynthian_ui_midi_cc_learn_02.png|400px|right]]
You can map any parameter in the Zynthian UI to a CC knob/slider on your external MIDI controller. I intend to extend this feature to other MIDI messages, but currently only CC messages are supported. Until then, MIDI-filter rules can be used instead.
Learning a MIDI-CC is quite easy:
'''1.''' From the control screen, you click the snapshot button. You will be in CC MIDI-learn screen. It’s identical to the Control screen except that all the controllers have a tiny yellow “???” in the bottom.
'''2.''' Move a zynthian controller. Its tiny “???” will change to green while the other 3 will go back to normal state.
'''3.''' Finally, move a knob/fader in your MIDI keyboard/controller and the binding is done. The new CC number should appear in the bottom of the learned controller, replacing the tiny "???".
Of course, MIDI-learning configuration, including CC mappings, is stored and restored with snapshots.
'''Technical Note:''' MIDI-CC learning works with all the engines. It uses the engine’s native MIDI-learning capabilities when available. Zynthian’s MIDI-filter mappings are used for the rest. To be more explicit, native MIDI-learning is used for MOD-UI and ZynAddSubFX OSC parameters. All the other parameters are managed by Zynthian’s MIDI-filter mapping.
<br clear=all>
====MIDI Program Change & ZS3 (SubSnapShots)====
[[File:Zynthian_ui_midi_zs3_learn.png|400px|right]]
A ZS3 (SubSnapShot) saves the state of the active layer in the context of the current snapshot (layer layout). When recalled, the saved state is restored and the active layer is changed.
Every ZS3 includes:
- Layer ID
- Bank Name
- Preset Name
- Controller Values
Once a set of layers has been created (i.e. loading a snapshot), ZS3 loading is very fast in comparison with loading snapshots, as no engine have to be started. It take less than 1 second in most of cases, and you can map ZS3s to MIDI programs very easily using MIDI learning.
The idea behind this feature is to have a fast preset-change mechanism that can be used on stage. In combination with the “Stage Mode” feature, it turns Zynthian into a “Stage-Beast”. You can prepare a snapshot for the full performance, and use ZS3s for fast changes from a song to another, or between parts inside the same song.
Learning to create a SubSnapShot is obscenely easy:
'''0.''' Ensure "Program Change ZS3" is enabled in the admin menu.
'''1.''' From the Control screen, short click the snapshot button to enter MIDI control learn mode then short click the snapshot button. You will see the current list of ZS3s (initially empty) and a message: “Waiting for Program Change…”
'''2.''' Push a “Program Change” button in your keyboard/controller and the ZS3 will be stored in memory, associated with the Program Number you pushed on your keyboard/controller.
After that, you can recall the stored ZS3 by pushing the same Program Change button again. Of course, stored ZS3s will be saved with your snapshot and restored on load.
You can update and delete stored ZS3s by bold-clicking on the list.
ZS3 behavior depends of the mode your zynthian is working on:
* Network Info - displays the IP address (ifconfig inet addr)
* '''Stage Mode''': ZS3 list shows all the ZS3s stored, no matter the layer. Recalling a ZS3 changes the active layer, so the layer associated with the recalled ZS3 will receive *ALL* the MIDI input. Only 127 ZS3s can be stored.
* Start WIFI - Starts or Stops WIFI (toggle)
* '''Multi-timbral Mode''': ZS3 list shows the ZS3 of the currently active layer only. Recalling a ZS3 changes the active layer, but every layer receives MIDI input from its channel. You can use several keyboards on different channels and store 127 ZS3s by MIDI channel.
* Start Audio Recording
* Test MIDI - plays the test.mid file

===Overview===
These simple tools allow you to record Audio & MIDI tracks easily, using the internal SD-card or an USB memory stick for storing the files.
It's also used when you want a quick way to upload sound samples to websites via the webconf component detailed below...
Most sites would prefer you to upload compressed files and oggs are perhaps the way forward . . .
For accessing the Audio & MIDI recording tools:
* From the '''Main menu''', select Audio Recorder
* From any place, '''long-snapshot'''
When you are in, '''short-snapshot''' for switching between Audio & MIDI Recorder.
'''WARNING!''' Using the internal SD card for storing the captured files increase the risk of corruption. You should avoid it by simply plugging an USB memory stick instead.

==Step Sequencer==
Zynthian has a step sequencer which provides methods to create patterns and arrange them into sequences.
The step sequencer may be accessed from the main screen or by clicking long-LAYER.
* There may be up to 999 patterns, each with as many simultaneous notes (polphonic) as required over a set of steps and beats that are configurable for each pattern.
* Patterns are arranged into tracks within sequences.
* Sequences may be configured to loop or play once and may be grouped so that starting one sequence stops another. Sequences may start and stop at the start of each bar.
* Note entry can be performed from the Zynthian user interface or using an external MIDI controller.
* Sequences can be started and stopped from the Zynthian user interface or using an external MIDI controller.

===Touchscreen Calibration===
Zynthian supports touchscreen operation for most operations. To ensure good alignment of the touch interface there is a calibration screen that is accessed from the Admin menu.
[[File:Touchscreen_calibration_1.png|400px|right]]
When the screen opens it shows a target crosshair in the center of the screen and a countdown timer. If the timer expires the screen will close without applying any calibration. Touch the target to detect the screen and begin calibration.
<br clear=all>
<br clear=all>
[[File:Touchscreen_calibration_2.png|400px|right]]
[[File:Zynthian_ui_midi_zs3_learn.png|400px|right]]
The name of the detected display is shown at the bottom of the screen. Further targets will appear. Touch the screen, drag to centre of target and release.
When the screen is pressed the target will show red. When released the measurement is taken and the next crosshair target appears white.
<br clear=all>
[[File:Touchscreen_calibration_3.png|400px|right]]
After releasing the last target, calibration is applied and the screen closes. Touch is ignored if too close to previous touch.
Use BACK button or wait for timeout to cancel calibration. Timer is reset to 15s when screen is touched and paused until released. The purpose of the timeout is to avoid users of Zynthians without back button being stuck in calibration screen view.
{{NoteBox| The resistive touchscreen works better with a stylus. Finger is too coarse. It's strongly recommended to run the calibration using a stylus. }}

====MIDI-CC Learning with touch interface====
= Touch Screen UI=
[[File:Zynthian_ui_top_bar.png|400px|right]]
You can navigate and control the Zynthian UI without knobs/encoders/switches at all, using only the touchscreen (or mouse).
You can "emulate" the switches by tapping the controller widgets (squares in the 4 corners of the screen). There are short, bold and long actions, same behaviour than rotary encoders work-flow. The only screen having the 4 controller widgets is the "Instrument Control" screen. Most of screens are selectors, which only have 1 controller widget. On those screens you can click the '''zynthian logo''' (top-right) to emulate the "snapshot" switch, and you can go back by tapping the '''top-bar''' area.
You can change the controller values by "sliding" up/down over the widgets. (see the green arrow in the figure) This is the same as turning the knob. If you are using a mouse, the mouse wheel also can be used to change the controller value.

These actions are available using MIDI messages on the Master Channel (default 16, but configurable with the webconf tool), specifically, note-on messages (0x9) are used so you can use a MIDI keyboard for controlling the Zynthian UI. For instance, to Power Off the zynthian, you send this message:
These actions are available using MIDI messages on the Master Channel (default 16, but configurable with the webconf tool), specifically, note-on messages (0x9) are used so you can use a MIDI keyboard for controlling the Zynthian UI. For instance, to Power Off the zynthian, you send this message:
0x9F ( Channel 16 Note ON)
0x9F (Channel 16 Note ON)
0x00 ( Note code for POWER_OFF as below )
0x00 (Note code for POWER_OFF as below)
0x00 (Velocity/parameter)
0x00 (Velocity/parameter)
or play the A-3 key, if your keyboard have it ;-)
or play the C-1 key, if your keyboard has it.
Note that you can use the velocity for sending the CUIA parameter when it's required by the action (SELECT & LAYER_CONTROL).

==Controlling the UI with OSC messages==
The same CUIA calls are available using OSC on UDP 1370, with the base prefix "/cuia". Take a look to "[[Accessing_Zynthian_from_your_computer#OSC|Calling CUIA with OSC]]".
