Automation using midi keyboard

[nirospring]

I want to be able to mute and unmute tracks while the song is playing and be able to save these using automation.

Ideally I would want the track to play (unmute) only if I'm holding an assigned note down on the keyboard.

Is this possible?

In Reaper, close to everything is possible (when using certain Add-Ons or script programming).

I am not sure if ReaScripts can be triggered by Note-on / Note off events, but I think they can be triggered by certain Midi events, and they can mute/unmute tracks.

If they can't accept Note-on / Note off events, you would need to convert Note-on / Note off events to CC events in a track FX (using some JSFX script) and then send the CC events to the Reaper control stream by "MidiToReaControlPath".

If there is no "built-In" way to trigger ReaScripts or use other Actions for the track activation, you can use SWS LiveConfigs to run arbitrary actions triggered by Midi CC events.
