[PD] MIDI latency problem
Hi, I have a little *problem* with *MIDI latency* (linux Mandriva 2010.0): - if I make a patch to generate midi notes repeated, with a metro (for example [metro 200]) I listen the rithm irregular (instead in Windows -on the same pc- the rithm is perfect..) -if in the same patch I change [metro 200] in [metro 10] the midi notes output goes in crash, is'n possible play midi notes speadily (instead in Windows -on the same pc- this is possible). -instead if I make an oscillator with a slide, the pitch of sound change *perfectly in realtime*. So the problem is only of MIDI. __ My settings: -in "/etc/security/limits.conf": * - rtprio 0 * - nice 0 @audio - rtprio 89 @audio - memlock 288000#My RAM = 576MB @audio - nice -10 -in "/etc/modprobe.preload": realtime mlock=1 gid=81#My user is in the "audio" group. ___ -in "qjackctl": realtime: on priority=89 frames/period=128 sample rate=44100 periods/buffer=2 port maximum=256 timeout=200 output latency=6 latency: 5.8msecmidi: seq _ in "puredata": -I run pd with: pd -rt -jack -channels 2 -In "media" I set "jack" and "ALSA MIDI"._ Any suggestion for this problem?

With this jack run correctly! ..sound is clean, without noise. Thank you! :)

When I run pd, in "media" I see: "jack" and "default midi" already setted. I
change only "default midi" in "alsa midi".
Then I open "qjackctl" panel, and I found 3 windows:
- in the first ("audio") I must connect manually "pure_data_0" with "system".
-in the second window (midi) I don't set anything.
-in the thrd window ("Alsa") I found already all connected.

Now I listen also MIDI notes, and this is due to a connection between
"puredata" and "timididy" in "Alsa" window of qjackctl.
But I have a little *problem*:
- if I make a patch to generate midi notes repeated, with a metro (for example
[metro 200]) I listen the rithm irregular (instead in Windows -on the same pc-
the rithm is perfect..)
-if in the same patch I change [metro 200] in [metro 10] the midi notes output
goes in crash, is'n possible play midi notes speadily (instead in Windows this
is possible).
Any suggestion for this problem?
Thanks,
c

Thanks.. I've resolved the problem of "user" adding (as root) those rows in /etc/security/limits.conf: @audio - rtprio 80 @audio - memlock 288000 #288000 because my RAM is 576 MB @audio - nice -10 and I set user in "audio" member group. ___ In JACK setup I set: realtime, priority 80 midi driver: seq ___ So now I can open qjackctl and start JACK correctly (play), but give me this error: cannot use real-time scheduling (FIFO at priority 90) [for thread -1238557840, from thread -1238557840] (1: Operation not permitted) Now I open pd, and in "media" I select: JACK, and ALSA-MIDI. Then I open JACK connections: I see 2 windows: AUDIO and MIDI. Here, in both windows, I connect pd with my SB LIVE! sound card.

[PD] problem with MIDI (linux)
Hi, I have a problem with pd 0.41.4 on Linux Mandriva 2010. I run JACK (qjackctl from terminal as root), and then I open pd. If in "media" I set: ALSA, ALSA-MIDI, in "testtone" audio is ok, MIDI is mute! If in "media" I set "jack", audio and midi in testtone are mute. (In jack connections, pure data is connect with snd_emu10k1...) My sound card use "snd_emu10k1" driver. I can listen correctly MIDI with Timidity...,sound from cd or YT..) sound card is ok) Any suggestions? thanks _ Carica e scarica in un clic.
