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
P.S.: my o.s. is Mandriva 2010.0
