You can navigate and control the Zynthian UI without knobs/encoders/switches at all, using only the touchscreen.

You can "emulate" the switches by tapping the controller widgets (squares in the 4 corners of a Controller screen). There are short, bold and long actions. Exactly the same workflow as with hardware knobs. The only screen that currently shows the 4 controller is the "Instrument Control" screen, so some features are only accessible from there. When the "back" widget is not available, you can go back by tapping the top bar.

You can change the values of the controllers by "sliding" over the widgets. This is the same as turning the knob. If you are using a mouse, the mouse wheel also modifies the parameter.

When clicking (tapping/touching) the topbar, a "back" event is triggered. It's a quick & dirty fix and probably it will change in the future, but meanwhile it will enable you to fully control Zynthian using the touchscreen if you don't have knobs hardware.

It allows to easily bind any parameter from the Zynthian UI to any CC knob/slider from an external MIDI controller. I intend to extend the feature to other MIDI messages, but currently only CC messages are supported. Anyway, MIDI filter rules can handle these special cases, so it’s not an urgent task.

This allows you to easily connect any parameter in the Zynthian UI to any CC knob/slider on an external MIDI controller. (I intend to extend this feature to other MIDI messages, but currently only CC messages are supported.) Anyway, MIDI filter rules can handle any special cases, so it’s not an urgent task.

It works with ALL the engines, using the engine’s native MIDI-learning when available (and convenient) or the Zynthian’s MIDI-learning mechanism, based in the MIDI filter. To be more explicit, native MIDI-learning is used for MOD-UI and for ZynAddSubFX OSC parameters. All the MIDI-mapped parameters are managed by the Zynthian’s MIDI-learning mechanism.

You get on-screen feedback during the learning process. When you enable the MIDI-learning for a parameter, a small green text with the string "??" appears on the botton side of the controller/parameter area in the Zynthian UI. When the parameter is bond, the number of the linked CC is shown in the same place.

  3. In 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 "boolean" parameters (i.e. on/off).
