Thanks Miller ! > -nosound -udiobuf 5 -slepgrain 1 Definitely academic :)
But I run intense audio on this PD instance, together with midi driving lights in real time. here are the flags : -rt -noadc -midioutdev 1,2 -audiooutdev 2 -outchannels 8 phasor~ would not do it ? or clipped cos~ ? maybe simply change MIDI interface to without-driver model.
