You can change the controller values by "sliding" up/down over the widgets. (see the green arrow in the figure here) This is the same as turning the knob. If you are using a mouse, the mouse wheel also can be used for changing the controller value.

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.

====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 must be started.

====MIDI-CC Learning with touch interface====
 +
 +
First, you need a working touch interface in your display. If you don't have a touchscreen, you could use a mouse ...
 +
 +
[[File:Zynthian_ui_midi_learning.png|400px|right]]
 +
'''Learning:'''
 +
1. In the "Instrument Control" screen, navigate through the parameter screen list to get to the parameter you want to learn.
 +
2. In the parameter/controller area, slide with your fingernail from '''left to right'''. A green "??" should appear at the bottom.
 +
3. On your MIDI controller, move the desired knob/slider (or a CC-assigned pad).  The green "??" should be replaced by a tiny number, and the parameter should change when you move the knob/slider or push the pad. CC-assigned pads can be very useful for on/off parameters.

'''Unlearning:'''
 +
1. In the "Instrument Control" screen, navigate through the parameter screen list until you get to the parameter you want to unlearn.
 +
2. In the parameter/controller area, slide with your fingernail from '''right to left'''. The tiny number, indicating the current CC assignment, should disappear or change. If the parameter is an engine-specific controlled engine, the number will disappear. If the parameter is a hardcoded MIDI-mapped parameter, then the number will change.
