I am working on a plugin to tune setBFree using MIDI.
Everything is working well except the back notifications.
Basically setBFree can be controller using MIDI, and can notify back the state of the synthesizer using MIDI. For example you can ask to apply a preset, and it will answer to location of each drawbars, and other stuffs. It’s fine. That’s a common design.
But i am stuck with the notifications, and i have no idea what to do with. It looks like that is no way to update programmatically a LV2 control port. Then no way to update the GUI. Is that right? Sounds crazy to me.
I just found https://github.com/drobilla/lv2/tree/master/plugins/eg-params.lv2 but it is not really what i want. Or is there a tutorial or an explaining how to use “Parameters” within the Mod GUI?
Or if somebody knows a plugin which can display MIDI input, there is maybe the recipe inside.
