Line 262: − − <br clear=all> − − ==Chains== − − Chains are a key concept of the Zynthian. The first thing you do after powering on your Zynthian is probably to create a chain. (It does little without any chains.) − − A chain is one or more interconnected engines capable of generating or processing audio or MIDI. Each chain is normally assigned to a MIDI channel. These engines are chained in the same order they are created, but you can change the order from the '''Chain Options''' menu. The first engine in a chain is the '''root''' and it determines the chain's type: − − * '''Synth Chain''' => Receives MIDI note-events and generate audio output − * '''Audio Chain''' => Receives audio-input and generates audio-output − * '''MIDI Chain''' => Receives MIDI-input and generates MIDI-output − * '''Generator Chain''' => Generate audio output using an algorithm − * '''Special Chain''' => Does not fit any other chain type, e.g. MOD-UI pedalboard, Pure Data patch, etc. − − The root engine can't be re-arranged or changed. MIDI effects can be added to the start of a chain and audio effects can be added to the end of a chain. These can be arranged as serial or parallel paths. − − All engines in a chain receive all the MIDI events on the assigned channel. Some special chains (MOD-UI) don't have an assigned MIDI channel and receive all MIDI channels. − − <br clear=all> − − When you select '''NEW Chain''', you create a new chain, choosing its root engine (first engine of the chain), a free MIDI channel and if available, a preset from a bank of presets. You can create up to 16<sup>*</sup> chains, one per MIDI channel, each having an independent MIDI chain and audio effect chain. − − <sup>*</sup> If '''Master Channel''' is enabled then only 15 chains can be created. − − Having several chains on the same MIDI channel is not allowed. If you want two or more chains to play in unison (like being on the same MIDI channel), you can use the "Clone" feature, which allow you to bind several chains while keeping MIDI CCs and other MIDI messages (Program Change, Channel Pressure, etc.) independent.

→Controlling the UI with OSC messages
=General Concepts=
=General Concepts=
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 core Zynthian UI consists of a display and four knobs with push switches. You can also control the UI with a touchscreen, a mouse or a keyboard (computer keyboard or MIDI keyboard, both!)
The four 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.
The four knobs with switches are the primary control mechanism to navigate the UI:
* '''Accessing the different screens'''
* '''Selecting options on menus and lists'''
* '''Adjusting parameters'''
Most operations may be performed with the touchscreen but some may not be intuitive. See the section on [[#Touch_Screen_UI|touchscreen]] and comments throughout this documentation.

===Chains===
Chains are a key concept of the Zynthian. The first thing you will do after powering-on your Zynthian is probably to create a chain. (It does little without any chains!)
A chain is composed of one or more interconnected blocks, capable of generating or processing audio & MIDI. Each chain is normally assigned to a MIDI channel. These blocks are chained in the same order they are created, but you can change this order from the '''Chain Options''' menu. The first block created in a chain is the '''root''' and it determines the chain's type:
* '''Synth Chain''' => Receives MIDI note-events and generate 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.
<!--* (Oram) '''MIDI + Audio Chain''' => Receives MIDI + Audio input and generates MIDI + Audio output. It has MIDI and audio-FX processors.-->
* '''Generator Chain''' => Generate audio output using an algorithm. The first processor is an audio generator.
* '''Special Chain''' => It can contains special processors, like an AudioPlayer (sampler), a MOD-UI pedalboard or a Pure Data patch, etc.
<br>
The chain's type can't be changed. Depending of the chain's type, MIDI processors can be added to the start of the chain and audio processors can be added to the end of the chain. Chain processors can be re-sorted and arranged as serial or parallel paths.
<!--
(Oram) All chain types, except Audio and Generator chains, have a MIDI channel assigned. MIDI channels are not exclusive anymore and you can assign the same MIDI channel to several chains. MIDI and MIDI+Audio chains can receive '''all MIDI channels'''.
(Oram) In MIDI+Audio chains, all audio processors in the chain receive all the MIDI events on the assigned channel (this should be improved!).
-->
(*) If Master Channel is enabled, this is excluded from the MIDI channels available for chain assignment.
Having several chains on the same MIDI channel is not allowed currently. If you want two or more chains to play in unison (like being on the same MIDI channel), you can use the "Clone" feature, which allows you to bind several chains while keeping MIDI CCs and other MIDI messages (Program Change, Channel Pressure, etc.) independent.
<br clear=all>
===MIDI input===
Each chain receive MIDI input from selected devices (keyboards and other MIDI controllers). You can configure the MIDI input devices from the chain's option menu. Use short-push for selecting the devices and bold-push for changing the input mode. All input devices are selected by default when creating a new chain.
Each input device can work in 3 different modes:
* '''ACTI:''' only the active chain receives all MIDI input from the device and all MIDI events are translated to the active chain's MIDI channel. It's the default mode.
* '''OMNI:''' each chain receives all MIDI input from the device and all MIDI events are translated to each chain's MIDI channel.
* '''MULTI:''' each chain receives MIDI from the input device in the configured MIDI channel. No MIDI channel translation is done.
When using ACTI mode you don't need to worry about the MIDI channel your keyboard/controller is using. You change the instrument you play by changing the active chain in your zynthian. You can change the active chain by simply rotating the select knob (#4) in the Mixer view or using the the left/right arrows.
In the other hand, MULTI mode allows receiving and managing separately every MIDI channel. Each MIDI controller will drive the chains assigned to the controller's MIDI channel. If you are using a MIDI controller that can sequence multiple tracks (Beatstep Pro, Keystep Pro, Novation Circuit etc.) then you will generally want to use this mode.
Finally, OMNI mode allows one or several chains to receive all MIDI input from your device translated to chain's MIDI channel. This can be useful for some use-cases. Be warned that this mode will be dropped in the near future so you should avoid it.
Note that MIDI CC (Continuous Controllers) events are handled differently and they are not routed to chains. See section on [[#MIDI-learning_.2F_binding|MIDI Learning & binding]].

The home screen is the Mixer and it's always reachable by pressing bold-Back. Navigation between views is performed by pressing buttons or using the touchscreen. Most destructive changes, e.g. removing chains, will request confirmation. Operations that take time to complete may show an animated zynthian logo representing progress.

A ZS3 (SubSnapShot) saves the zynthian state in the context of the current snapshot. When recalled, the saved state is restored. The chains are defined in the snapshot but their selected preset, parameters and mixer settings are defined in the ZS3. Snapshots can be slow to load as each engine needs to be started. ZS3 is much faster as the presets are restored and parameters adjusted. Some ZS3 may be slower due to the way some engines load presets, e.g. changing instrument within Pianoteq is slower than recalling a preset of the same instrument.
A ZS3 (SubSnapShot) saves the Zynthian state in the context of the current snapshot. When recalled from the UI or by MIDI Program Change, the saved state is restored. The chain's layout is defined for the snapshot and it can't be changed across ZS3s, but the rest of state is saved in ZS3: bank/preset, engine parameters, mixer settings, clone & key range settings, etc. Snapshots can be slow to load as each engine needs to be started. ZS3 is much faster as the presets are restored and parameters adjusted. Some ZS3 may be slower due to the way some engines load presets, e.g. changing instrument within Pianoteq is slower than recalling a preset of the same instrument.
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 between songs or even within a song.

The audio player shows transport and other configuration controls and draws a waveform image. Start playback by changing the transport from "stopped" to "playing". Playback position is indicated by a vertical line on the waveform and the "position" controller value (in seconds). Playback position can be adjusted. One-shot or loop playback is available. Selection of which channel in the audio file (or a mix of all odd / even channels) is sent to each output, e.g. for a 4 track audio file you may select any of the four tracks to feed left or right output or select mixdown to mix tracks 1 & 3 to left output and 2 & 4 to right output. There is also a gain control.

The settings vary between sound cards. The official V4 soundcard has these settings enabled in webconf by default:
* ADC Left - Level adjustment of the left input
* ADC Right - Level adjustment of the right input
* ADC Left Input - Configure left input connector:
** No Select - Disconnect input
** VINL1[SE] - Tip & sleeve single ended/unbalanced
** VINL2[SE] - Ring & sleeve single ended/unbalanced
** VINL2[SE] + VINL1[SE] - Tip, ring & sleeve single ended/unbalanced
** [VIN1P, VIN1M][DIFF] - TRS differential/balanced
* ADC Right Input - Configure left input connector:
** Same options as ADC Left Input
* Digital Left - Level adjustment of left output
* Digital Right - Level adjustment of right output
* PGA Gain Left - Gain adjustment of left input
* PGA Gain Right - Gain adjustment of right input
Note that the gain adjustment allows coarse control of the overal gain of an input, allowing configuration for line, mic, etc. The level adjustment is an overal 0…100% level.
The input connector configuration can be useful for a few variations:
* Balanced signals on TSR - [VIN1P, VIN1M][DIFF]
* Unbalanced mono on TS - VINL1[SE]
* Two unbalanced (e.g. stereo) on TSR mixed to mono - VINL2[SE] + VINL1[SE]
