When we create a multitimbral plugin, say Falcon, we have the facility to automatically create MIDI input and audio output tracks. These are regular Reaper tracks like any other. What would be convenient is to have these extra tracks considered part of the main track, rather than individual tracks. This is just a workflow thing: at present the tracks must be manually organised into folders, when the common case is that the MIDI and audio channels are a logical part of the multitimbral synth's track.
