Hi, I'd like to use Pd for midi processing, and I'm trying to find the flags to have the best "Pd for midi" possible. For me midi latency is an extremely important factor, so all my efforts were in the way to optimize it. I did some experiments, playing with flags and seeing what happens (I use Pd 0.43.1 on Debian Wheezy, with jack 44.100 - 128 frames):
With -rt -jack -audiobuf 1 -alsamidi I get 2.9 ms of midi latency
Adding -noaudio I get two possible values: 1.45 or 2.9 ms
Adding -r 192000 I get 1.33 ms
I don't know why I have to modify the sample rate (-r) to affects the midi latency. Feedbacks are appreciated :-)
thanks
