Thanks for the answer,
Looks pretty complicated as I never did any scripting
Could I use any of already existing presets? (maybe i could map some of the knobs then?)
and another, probably pretty dumb question - how could I control VST instrument parameters using knobs of MidiKeyboard?
I could not find it in midimapping options when checking Available & Active Mappings
That’s cool. However, one of the first things written on the Duplex tool page is “Duplex is optional”.
Duplex can do clever things like allowing you to roam between effects and mixer channels, but I think you could do most of things you want without it -
Maybe your setup doesn’t need to be any more complicated than this:
For the VST instrument, use the MIDI Input settings to select your keyboard. This will make the notes from the Keylab arrive into the instrument, no matter which instrument you have selected in Renoise
For the parameters, create a Instr. Automation device and MIDI-map the parameters you want. Then save this DSP chain to disk (right-click, “save as”)so you can reuse it later on.
Obviously, it would be nice to have Duplex support for the Keylab too. But it’s mostly a traditional one-to-one controller and not some fancy modern grid controller that would need to be told what to do before being useful.
