=The Zynthian UI Workflow=
The following flowcharts show the different "screens" or "menus" and how to reach each one using the 4 switches.
It would be a good idea to print these flowcharts and keep them near your Zynthian Box until you memorize the workflow.

This is the first screen you would see when you power on your zynthian for first time and no default snapshot or last-state snapshot has been saved yet.
The Main menu gives easy and intuitive access to the Zynthian-UI's main features:

You can access this menu by '''Bold-clicking the Back knob (CTRL-2)'''.
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 on this way, but until you learn the shortcuts and feel comfortable with them, you will find this menu very useful.

Layers are a key concept on Zynthian-UI: the first thing you do when you power-on your zynthian is, probably, create a layer.

All units in a layer 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.

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, which allow you to bind several layers while keeping MIDI CCs and other MIDI messages (Program Change, Channel Pressure, etc.) independent.

When you create a new layer, you are asked which engine/plugin you want to use for it. A list of engines to choose from is displayed. They can be synthesizers, effects, generators or special engines, depending on the type of layer you are creating. When you select an element from the list, the zynthian logo on the top-right will be animated while the engine is being started.

====Tips====
==MIDI-learning==
You can press the Layer switch to step over the layer list. If you bold-press, the layer list screen will be shown.
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>
<br clear=all>
==Snapshots==
====MIDI Program Change====
[[File:Zynthian_ui_midi_zs3_learn.png|400px|right]]
You can map "SubSnapshots" (ZS3) to MIDI programs. The idea behind this feature is to have a fast preset-change mechanism that can be used on stage. In combination with the “Single Layer” feature, it turns Zynthian in a “Stage-Beast”. You can prepare a snapshot for the full performance, and use ZS3 for fast changing from a song to another, or between parts inside the same song.
Learning a SubSnapShot is obscenely easy:
'''1.''' From the control screen, you click the snapshot button '''twice'''. You will see the current list of ZS3s and a message: “Waiting for Program Change…”
'''2.''' Simply push a “Program Change” button in your keyboard/controller and the ZS3 will be stored in memory, associated with the Program number you send.
After that, you can recall any stored ZS3 by simply pushing the same PC button again. Of course, the memory-stored zs3s will be saved with your snapshot and restored when loaded again.
Every zs3 includes:
- Layer ID
- Bank
- Preset
- Controller values
As you can see, it has sense in a SnapShot context, where a set of layers are defined. Zs3 changing is very fast, as no engine have to be started.

==Load/Save Snapshot==

[[File:Zynthian_ui_snapshot_save.png|400px|right]]

Snapshots are used for saving and restoring the status of Zynthian. A snapshot includes the full state, including layers, effects, parameter values, MIDI-learning, etc.
Snapshots are used for saving and restoring the status of Zynthian. A snapshot includes the full state, including layers, effects, parameter values, MIDI-learning, etc.
You can enter the ''Load Snapshot'' screen by clicking the snapshot switch. From the control screen you have to use bold-click. A second click and you will be at the ''Save Snapshot'' screen. You can also use bold-click to go directly to the Save Snapshot screen (not from control screen!).
You can enter the ''Load Snapshot'' screen with '''bold-snapshot'''. It works from any place. A second click and you will be at the ''Save Snapshot'' screen.
Before loading any snapshot, you should save one, and to save a snapshot, you should create some layers, etc. The Zynthian UI will use numbers for naming the banks and snapshots. You can rename the snapshots to something more specific using the webconf tool.

====Restore Last State====
====Restore Last State====
If "Restore last state on startup" option is enabled on webconf (it's enabled by default), then the state will be saved when powering off (using long-click select or from Admin Menu) and restored on next boot. This option has priority over the "Default Snapshot".

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 to store the captured files will increase the risk of corruption. You should use a USB memory stick instead.

* Selecting "ALSA-Mixer" option from the Main menu

'''1.''' From the control screen, you click the snapshot button '''twice'''. You will see the current list of ZS3s and a message: “Waiting for Program Change…”
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.
