Hi Mario, In qjackctl my config is (my parameters names are in French so maybe my translation is not the exactly same) : Samples/Period: 4096 Sample rate: 44100 Period/Buffer: 2
Midi Driver: None I call ChucK (Jack version) with parameter --bufsize8192 What is the specific setup your are talking about ? Thanks!
