[PD] MIDI Latency!!!

[matohawk]

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
