[linux-audio-dev] jack, low latency and IO

I'm a bit puzzled with this one thing about low latency and jack: real time bits can't do IO, but don't you get latency between say me pressing some button and sound doing click? there's no garanty the not realtime part of the application will run often enough to read the input device, no? just recently some heavy process started when i was fulling around with some soft synths [i know that shouldn't be happening, but i just recently switched distros and I haven't learned enough to write dont-bother-me script to switch all potential sources of disturbance] and the GUI of the soft synth became quite irresponsive, while audio went on without any glitches - that's I suppose because the audio part was running in realtime thread and decided itself when to yield cpu. is the only way to ensure the effects don't lag from control input to make sure I run as little processes as possible and hope the input thread will be scheduled often enough? -- Artem Baguinski: http://www.artm.org/ V2_Lab: http://lab.v2.nl/ V2_ Organisation for the Unstable Media: http://www.v2.nl/
