Sorry if this is stupid question, but is there a way of muting channels on the fly using number keys like you could on Octamed?
There is a shortcut for muting the channel that the cursor is currently positioned on (also works with a selection spanning multiple channels), but no shortcuts for muting specific channels - as OpenMPT supports many more channels than OctaMED, that approach simply wouldn't work (you could only apply it to the first 10 channels assuming that you have something like Ctrl+Number keys for muting, making it pretty useless in the general case).
I just a thought about a 'workaround'
MIDI Device (keyboard or pad controler) into MIDI Interface
PureData patch to transform a range of NoteOn (lets say C3-C5) into CC Messages
Send this CC via a loopbackMIDI to OpenMPT
use PlugIn slots (lets say 100-123) each with its own instance of a mute plugin (moot by DLM provide a midilearn button but I havn't tried it yet)
route the channels 1-24 to the plugin slots 100-123
connect the incoming CC via the MIDImapper to the mute plugins
a bit messy I know :) What is your thought on this Saga?
I mean sure, it could probably work... but is it worth the effort? :) It might also cause problems with existing plugin chains.
