Q about reaper.StuffMIDIMessage in Lua

[J Reverb]

Is it possible to increment the value of prg every time a script is run ?
I would like to set up program changes for a particular vst synth from the tool bar. I am wondering if the current value in this case 'prg' would need to be written to an external file for storing and updating ? Or maybe it's much simpler ?



prg = 0

reaper.StuffMIDIMessage( mode, msg1, prg, msg3 )


Thanks,


J.

This isn't so much a question about StuffMIDIMessage() but about how to store state.

Take a look at the Get/SetProjExtState() and Get/SetExtState() APIs.

Thanks tack

That's sorted it using Has/Get/Set tonumber and tostring.
Nice one for the heads up.
