Local OSC Latency

Post by bla »

Hi Jesse,

building a RPi looper and went to the trouble of looking into kernel modules to keep the gpio switch latency low. Would this be completely negated by system OSC latency and are there other feasible bindings (sysfs, mmap) without rewriting too much code? Great software dude.

P.

How will you be controlling it in practice, OSC or MIDI? Realistically, I don't think control latency is going to be an issue for you... as there is audio latency compensation for the important parts of loop timing. But I haven't personally tried RPi to see how things are there.

Finally got round to take some measurements (tinyosc, liblo might be higher): around a third millisecond. So yes, probably doesn't matter much even when latency compensation doesn't apply (first start/restart of loops with content at the very beginning, as I understand it).
