==The Zynthian UI Workflow==
 +
Zynthian workflow is based around chains of audio/MIDI generators & processors feeding an audio summing mixer.

===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
 +
* '''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 chain's type can't be changed. Depending of the chain's type, MIDI effects can be added to the start of the chain and audio effects can be added to the end of the chain. These can be arranged as serial or parallel paths.
 +
 +
All audio effects in a chain receive all the MIDI events on the assigned channel (this should be improved!).
 +
 +
When you select '''NEW Chain''', you create a new chain, choosing its root engine, a free MIDI channel and if available, bank & preset. You can create up to 16<sup>*</sup> chains, one per MIDI channel.
 +
 +
(*) If Master Channel is enabled then only 15 chains can be created.
 +
 +
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.

===Stage and Multitimbral Modes===
 +
 +
By default Zynthian starts in '''stage mode'''. Stage mode is a kind of ''Omni-On'' mode, what means all MIDI messages are sent to the selected chain in your zynthian. You don't need to worry about the MIDI channel your keyboard/controller is using. You can change the instrument you play by selecting it in your zynthian or using ZS3's Programs Change feature (see below).
 +
 +
In the other hand, '''multitimbral mode''' allows receiving and managing separately every MIDI channel. Each external MIDI controller will drive the chain that is assigned to that controller's MIDI channel, e.g. a chain assigned to MIDI channel 1 will listen for MIDI messages on MIDI channel 1 only<sup>*</sup>. 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 setting.
 +
 +
(*) MIDI Continuous Controllers are handled differently. See section on [[#MIDI-learning_.2F_binding|MIDI Learning & binding]].
