Hey Len, thanks for the insight. I never used OSC this way so far. I also did not know that there are existing RFCs for MIDI over RTP, which is very nice! So, yeah, lets do that. I will take a closer look at the code repos you posted. I definitly want to give this a try! But I am rather busy at the moment, so don't expect too fast progress in this matter ;-) BR, Ck Mittwoch, 29 August 2018, 09:00nachm. +01:00 von Len Ovens l...@ovenwerks.net :
