Hi all,
Does anyone use an M-audio device like MobilePre or FastTrack with success?
I've read in some archives that some peoples have try to use them, but i have
not find any clear feedback.
Some talks about firmware loading, others talks about usb compliance problem...
I plan to use it with a laptop shipped with Debian/DeMudi with custom recent
kernel (>2.6.9).
So if there is anybody outhere that is happy with its M-audio MobilePre or
FastTrack, please let me know.
regards,
Christian
PS: I am looking for a "cheap" USB audio interface in which i can plug a guitar
or a bass and a stereo microphone (for percussion or acoustic guitar).
I can easily buy m-audio devices, but the vendor doesn't have (many) edirol
devices...

No, But I can remember wanting to gice up on alsa due to the crappy
m-audio quattro.

hello,
i've just bought the mobilepre; it is "usb audio class" compliant and
works on linux 2.6 and BSD.
i didn't have enough time to test everything. This evening i'll have more
time to play with it. Feel free to contact me if you have specific questions
and/or if you want me to check something for you.

Great! thanks.
What i want to know is if it is "well supported", i mean all input/ouput are
usable, the sound quality is good (no noise), latency is OK (no large delay in
audio path and control path).
Do you know if it is an USB1 or USB2 compliant device?

i'm not a professional, but imo the sound quality is correct. There isn't
much noise, i've tried to plug the output of my synthesizer to the input of the
sound card and then i've run:
arecord -f cd | aplay -f cd
and imo, the result is good;
The mixer works, it's very simple; there are few controls (input gain,
output gain, dac gain, and direct monitor gain). The only feature that i
couldn't get to work on linux is the "direct monitor" (it controls the
amount of the input signal that is routed directly to the output).
i don't expect low latency from such USB hardware; i just plan to use it as
a simple full-duplex player/recorder. Do you want me to do some other tests?

This seems quite good.
Concerning the direct monitor, by default have you some input sound
routed to output? I mean without playing it back again with a software.

Have you some noticable output delay when playing an instrument on input?
I want to use it to record music from my band. Recording each track
separatly, while playing other tracks. So i need no audible latency, no
delay between the moment a note is played on the instrument and this
note is heared on speakers.

i'm planning to use this sound card for the same purpose (ie playing
multiple tracks while recording a single track). Imho, we don't need
low-latency hardware/software to do this; we only need to synchronize
playback to record and this can be easily achieved with large block sizes
even on a slow machine without preemtive kernel.
(on the other hand, softsynths and real-time effects need fast and
low-latency hardware/software)
i just tried to play a sample (44.1kHz, 16bit, stereo) and to record the
output of the sound card (by wiring its "line-out" to its "line-in").
On a
pentium 200Mhz running openbsd (sorry couldn't get to work my crappy
software on linux) the shift between playback and record is 6ms. this is the
time that the sound takes to propagate 2 meters. While this is enough for
me, i think that the shift will be much smaller on linux, especialy on a
better hardware/software.

i'm using linux v. 2.8.6 and alsa v. 1.0.4. (debian sarge)

Still with linux 2.6.8 but i have updated alsa to 1.0.10 (to get my UA25
working), i have also already updated ardour, jamin and jack (but have
switched back to original jack since i cant get it working).
Do you use these packages from debian, demudi or from manual install?

Christian

Hi Alex,
I finally buy an Edirol UA25. It seems to be similar in term of feature,
and i have read this type of card was well supported, unfortunately i am
facing some issue. However i can use it for my purpose, except for one
thing: i get jack/ardour/jamin crash when putting jamin as insert on
master track. This is under investigation....

How do you measure this delay? Are you using special software?
I am interesting to know the delay i have with my HW. (recent but
"cheap" laptop)

You would probably get fewer xruns with a more recent kernel like 2.6.14
- there has been a lot of work on the kernel to support low latency
audio since then.

OK, i have tried more recent kernel but my mother board is quite

I will make a mini-conference tomorow at Toulouse, France, the subject
is "musical creation with GNU/Linux", (for whom understanding french:
www.toulibre.org). But now it's too late to try again to get a newer
kernel (it's 2 AM!). I will discard the jamin demo.... :(
I will try in the coming days to get a working 2.6.14 kernel.
Thanks,
