No I didn't create an /.asoundrc. Am reading about that now. Its
part of the Alsa-Wiki. There is also a blurb about connecting midi to Pd in the same Wiki. I
hope this works out The idea of building a new kernel is I must say daunting. Anyway if I
know with a bit of work I can get this up and running then okay. In response to the other
email the card is working fine for basic things playing back wavefiles at different sample
rates etc and is listed named in alsa.conf etc. The only thing that doesn't work is midi I
can open pd with the -alsa commnand running in advanced mode at 44100hz no higher.(fine by me) but the
alsa midi won't connect (client 128) I'll look at that today.

moin Ede, moin list,

Well, I'm successfully running both MIDI and audio off the UA-25, also on debian (mostly) etch, and a ThinkPad T42...

First of all, don't use OSS (emulation) -- I've had no luck here with the UA-25 in "advance mode" and Pd; as you say, probably due to 24- bititude.

Do you have an ~/.asoundrc defined, and if so, what's in it? If
you're choosing from the pd "Audio Settings" menu, grab the "UA-25 (plug-in)" entries, rather than one of the "hardware" entries. Also, I've had to run pd with the "-rt" switch (which required getting realtime capabilities patches working: urgh) when using ALSA directly,
otherwise I get audio pops and eventual "tried but could not sync" errors.
fyi, I run pd here with:

moocow@binky:~$ cat which pd-ua25.sh #!/bin/sh ( pd -rt -r 48000 -alsa -channels 2 -audiodev 6 "$@" & ) ( sleep 5 ; aconnect-usb2pd.perl; jack-chrt.sh )

... where "aconnect-usb2pd.perl" does some magic with 'aconnect', and the (badly named) 'jack-chrt.sh' messes around with some scheduling priorities.

Important to note:

• pd's sample rate should probably match whatever you've chosen on

the ua-25

• use alsa.
• for me, "-audiodev 6" is the 6th entry in the drop-down list of

audio devices I get with the ua-25 plugged in (under normal circumstances), labelles "UA-25 (plugin)".

good luck, Bryan

After reading on the list about Edirol UA-25 I went out and got one on run on Debian. I can get sound when running in standard mode or midi in advanced but can't get both. I read on the list that some- one is running both midi and sound. Problem is the UA-25 seems to force 24bit in advanced mode which Pd won't run at or is there a way to get around this. Debian Etch Power Book 1.5 Edirol UA-25?

Okay. That works thanks a million!!

sorry if i am totally off topic, but i haven't read the entire thread. (esp. sorry if i am saying something obvious here)

you have to enable pd's alsamidi support in order to use it
(default is OSS/midi); use the "-alsamidi" flag to do so.

furthermore, pd does NOT autoconnect to the available hardware
devices. you have to do so by hand (aconnect, [aconnect], or qjackctl (which is handy as it comes with a gui)

and you have to switch your ua-25 into "advance" mode (there is a
switch at the back of the device)

i just tried this and it works:

• switch UA-25 to advance mode
• start "pd -alsamidi -mididev 1"
• start qjackctl
• in connections/MIDI you should now see "UA-25" and "Pure Data" and

connect them: voila

I don't quite follow: are you using JACK or the ALSA connection from pd? Or you mean jack-chrt is badly named because it's not actually doing anythign wth JACK?

I was about to get a UA 25 so am quite interested in how this works. With the builtin (intel HDA) I get pops when using JACK but not when I use the ALSA output . I did not get the pops with a different application, when using JACK, but just when using PD and JACK .. Though I've not exhaustively tested all applciations yet. But, I really want to get the sound stream from PD into another application and via JACK seems like the simplest way.

I also used to get subtle but audible pops every 30 sec or so using jack, and I never figured out why... maybe it's gone now ;-)

Interesting, that's kind of like what I was getting, I thought it was due to the Intel soundchip driver not-quite-there problem.

...

priority 89, frames/period 256, rate 48k, periods/buffer=3

I had to do periods/buffer=3 to get anythign to work without constant xrns with this intel. I'm surprised it's needed with the Edirol, or is it somehow to do with PD? Not that I know what 'periods/buffer' actually does...

So I went out and got one Edirol UA-25, and I definitely have fewer problems than with the builtin soundcard. On my debian - sid installation it worked straight out of the box for playback (havent' tried capture yet)

There's some remaining issues when using JACK with pd, it sometimes causes a timeout and then JACK gets mangled and does not recover; increasing the frames/buffer so far seems to solves it at an acceptable latency level for me, however. It does not seem to require 3 periods setting though I have not accumulated enough evidence to know if the time-out occurs more or less easily with different settings like that. I beilieve this is completely unrelated to which soundcard is used.

Whereas the other probems I had , continuios clicks no matter what settings, are gone when using the UA-25 (and supposedly the sound quality shoudl be better though I have not compared objectively).
