hello everybody,

i’m on a journey for debugging a more complex MIDI Presets program and i’m getting closer to the problem.
`outic` and `outkc` is not sending every value how i expect. it’s only sending values that changed in some kind of way.

i wrote a little .csd for showing the problem and a PD patch for printing these values. i expect that 30 values are printed in pd, but only 14 are printed.

maybe it has something to do with the MIDI protocol?

i hope someone with more knowledge about the MIDI protocol can test this.

i’m on MaxcOS, sending MIDI ouput from Csound over IAC to PD receiving on IAC and printing there.

Ahhh, yes. The problem was that outic and outkc were not the right opcodes for my purpose.
i needed the midiout opcode…

this was quite a hustle.
now back to loving csound.

thanks all!
