Toggle REC Button via Midi?

Is it possible to adress the state of the REC Button on Hermod Via Midi?
And where can I find a Midi Implementation chart? (remember those? right? : )
So that I could dedicate one Button on the Midi controller keyboard to toggle REC directly from where I play the Notes, rather than going back and forth between my keyboard and my modular case?

Thanks for any help : )
