Layers are a key concept on Zynthian-UI: the first thing you do when you power-on your zynthian is create a layer ;-)
+
+
A layer is an '''Audio Processing Chain''', normally assigned to a MIDI channel, that can be composed of one or several Audio Processing Units. This units are chained by default, although you can customize the audio routing. The first unit in a layer is the '''root''' and determines the layer's type:
* FX Layer => Receives audio-input and generates audio-output.
+
* Generator Layer => Auto-generate audio output using some algorithm.
+
* Special Layer => MOD-UI pedalboard, Pure Data patch, etc.
+
+
The rest of units in a layer normally are FX units that process the audio coming-out from the first unit (root).
+
+
All units in a layer receive all the MIDI events coming from the assigned channel. Special layers don't have an assigned MIDI channel and receive all MIDI channels.
