Hello all, somes questions here about midi process optimization :
the midi setup : a korg electribe send midi message (noteon and controlchanges) to an usb soundcard (umc204hd) connect by USB to puredata/gem to finally draw things on screen (3d objects, videos textures, shaders etc) (nvidia hardware and drivers)
all I want is to optimize midi latency and be able to draw things as fast as possible (considering this hardware) ie reduce the time between the midi event and the generated graphics
what I've done : reduce pd audio buffer to 3 use a 'delay line controler' to delay audio (something like 60ms is needed) and so retreive an 'good' A/V sync
I know that :
screen (nyquist)
soundcard I get around 2ms, which is very good ! (tested with pd and also with alsa-midi-latency-test)
any experience or advice on theses questions ? what are yours best setup/experiences to acheive really fast sync ? thanks you all
Pierre
