activating tracks via Midi

E30 Stu · Messages: 75 Registration: 12.06.2002

Hi experts, Is it possible to activate / deactivate tracks (including the embedded VSTs) via Midi "Program Change" messages (e.g. according to a list defining which tracks to be activate with any selected program) ? With that, (ab)using Reaper as a VST host for live performance would be a really good option. If such feature is not included in Reaper itself, maybe a Midi-only VST plugin could do the job, provided Reaper offers an API to allow a VST to enable/disable tracks (e.g. modify the Midi and Audio Routing appropriately and (optionally) power on/off the VSTs of a track. -Michael

Did really nobody consider this, yet ? -Michael

Could be done through Mackie MCU Protocol , you just need a midi input (not a channel) that can be defined as a control surface. ... And of course deliver the corresponding midi messages. See Or

Especially if you're a programmer, I figure you could also relatively easily build your custom setup using something like OSCII-bot used as a (virtual) OSC Control Surface. You'd make a script for OSCII-bot to convert the appropriate MIDI Program Change events into the appropriate OSC messages for REAPER's OSC Control Surface feature, which supports bypassing plug-ins in its default configuration (cf. the "FX_BYPASS" OSC action description in the Default.ReaperOSC file).

Thanks for the tip. I never heard of OSCII-bot, yet. I'll try to find out about same.... .... (later: ) According to the docs there is no dedicated WIN64 version, just Win32. Will the Win32 version be usable on Win64 out of the box ? Looking around from the starting point you provided, I also found the "JSFX Programming Reference". JSFX seems to be available with Reaper out of the box. So why do you recommend OSCII-bot, and how are the interpreters related / comparable with each other ? -Michael

The mcu protocol is nothing else than a well-defined set of midi messages. The description is linked in my post. The challenge will be to "mask" the midi provider that reaper will accept it as a remote control . Btw : just use an iPad , if you have.

I thought of using a virtual midi cable
