Hello Pd-list,
Do you have the same problem with midi and Pure Data, 50 or 60 miliseconds of latency?
I test it on windows and linux Ubuntu 2.6.24.
My test on windows is : Edirol UM-1SX with a midi cable out -> in and a small patch .
I made the same test on MAX/MSP with the same patch and I have 0 or 1 milisecond of latency
And on linux is pd midi alsa out -> pd alsa midi in (virtual connection).
Here, you can find snapshot of the pd test : Pd patch http://www.th-th.fr/DOCS/Images/BlankPages/PD-Test-MIDI.png Jack midi connection http://www.th-th.fr/DOCS/Images/BlankPages/Connections-%20JACK-Audio-Connect...
Someone can you explain why? Is that possible to reduce this?
Cheers Thomas Thiery
Hi friend: in windows install asio4all in linux install a kernel with low latency.Assign in the audio device... Best Regards

Hello Jose, Thanks for your answer, I have a debian lenny with the kernet rt (Pure dyne) 2.6.24.4 rt4 and pure data vanilla 0.41.4
Midi Latency = 58 - 62 millisecondes
I think asioforall it's only for audio and for MIDI latency.
But I don't know why Max/MSP is better than Pure Data with the MIDI latency?
Cheers Thomas
