Re: [PD] MIDI Latency!!!

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

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 :

Someone can you explain why?
Is that possible to reduce this?

Cheers Thomas Thiery
