Rui,
Thanks for your reply. I am trying to build Jack first
just to see if it'll work with the CCRMA Alsa I've
already got. So far I've done:
[root@localhost
jack-audio-connection-kit-0.99.35.3usx2y]# aclocal
[root@localhost
jack-audio-connection-kit-0.99.35.3usx2y]# autoheader
[root@localhost
jack-audio-connection-kit-0.99.35.3usx2y]# automake
configure.ac: required file `config/mkinstalldirs' not
found
I can't find anything about this file, not even in
configure.ac, and I really don't have a clue about
this kind of thing (sorry if it's something really
obvious). It certainly seems to stop the rest of the
build working though. Any ideas?
Thanks
Stefan Turner

The first patent should expire soon as their software Labview
was launched 1986. It contains some essential items.
I collected papers on this topic recently. In Labview user creates
the circuit editor and the control panel. Both existed alone
earlier. Labview includes special GUI elements in the circuit
(see Reaktor, for example). I'm in belief that this connection
can be done slightly differently without violating the patent.
When Csound type software was first written? 1960? 70?
There are other Labview patents. One patent patents what I have
invented prior them. I remember posting it to a mailing list, but
have not yet found it. I have not read the patent but my idea
was that when the module is a subgraph, a click on the module
opens up a graph editor; and when the module is a script, a click
on the module opens up a text editor. Obvious?

Ok, if it can get 2x128 that's quite tempting: I'd
always assumed the crackling was a USB1 thing... I'd
be grateful if you could give me a little help with it
though please. I'm running PlanetCCRMA Fedora Core 1
at the moment. From your page I gather that I need
jack-0.99.35.3usx2y.tar.gz. Am I right in thinking
that the 'linux' section is kernel patches? Is there
no way I can use this with the CCRMA 2.4.26-1 kernel
(with low latency, givecaps, preempt etc)?

Sorry I don't understand this at all. I can't find
anything about sand-usb-usx2y, but do you mean if I
installed latest alsa I could use sand-usb-usx2y in
place of snd-usb-audio in modules.conf?
Apologies for newbieness.

Hi all,
sorry for crossposting, just wanted to let everybody know:
The official statement is that there will be no support for ALSA (Linux)
FireWire drivers from RME. In other words there will be no such drivers,
as it is impossible to write them without tons of hardware and software
documentation from RME. And we won't share these information with
anyone.
Regards
Matthias Carstens
RME
No further explanations.
The moral of this story is:
Never buy a product that isn't already supported in ALSA, such as i did.
:( There's no guarantee even if pretty much every other card from the
same manufacturer *is* already supported.
Me and Benno talked to Matthias personally during Musikmesse, he was
friendly and seemed to be open with regards to future cooperation with
oss developers.
Seems like things have changed dramatically since then.

Hello,
have now figured out how to drive my audio and midi with tascam us-122 on SuSE
9.2 -- and (after disabling all tv thingies) it works very reliable and with
very few xruns.
The following software seems to be involved:
- linux-2.6.8-24.3 (SuSE Standard kernel -- heavily patched)
patched with linux-2.6.8-24-usx2y-0.8.6.patch from rncbc
(CONFIG_HPET_RTC_IRQ=n)
- realtime-lsm-0.8.5
- ruis jack
jack-0.99.21.1usx2y-17.suse92
- qjackctl-0.2.13-1
- rosegarden4-0.9.9-2
- ZynAddSubFX-1.4.3-141
With this configuration I have found a weird problem:
When starting jack with driver 'alsa' (from qjackctl) I am able to play my
alsa instruments (for example ZynAddSubFX) from within rosegarden:
- start ZynAddSubFX
- start rosegarden
- choose ZynAddSubFX for the active track
- play the keyboard an listen to nice ZynAddSubFX sounds ...
But when starting jack with driver 'usx2y' the midi seems not to arrive at
ZynAddSubFX (or Hydrogen or fluidsynth or ...) Even ASeqView doesn't show any
incoming events if chosen as instrument in rosegarden.
Restarting jack with driver alsa -- and all went well ...
What is the problem? And what can I do to help with this problem?
Are there any missing facts?
Yours
Uwe Koloska
(Somewhat related to recent threads.)
I see that the new Mackie mixers (the Onyx series) have the possibility
to put in a card with D/A converters and a FireWire connection to a
computer. I have bought one of these mixers, and might be interested in
bying such a card for recording purposes. But it will need to have
Linux drivers. How probable is it that Mackie will produce such
drivers, or release the necessary specs? And, if given specs, can
someone be persuaded to do a driver?
(According to what I have read, the the card works just "out of the box"
with Mac OsX's Core Audio drivers. While for MS Windows, drivers are
needed.)

Since this has been mentioned, my US-122 doesn't work
AT ALL using usx2y, but is fine with alsa. I am using
qjackctl 0.2.13 and Jack 0.99.0 (the most recent
versions AFAIK). All I get is:
17:47:12.866 JACK is starting...
17:47:12.867 /usr/bin/jackstart -R -dusx2y -dhw:1
-r44100 -p512 -n3 -H -M
17:47:12.873 JACK was started with PID=6369 (0x18e1).
back from read, ret = 1 errno == Success
jackd: unknown driver 'usx2y'
17:47:12.885 JACK was stopped with exit status=1.
17:47:14.885 Could not connect to JACK server as
client.
This doesn't bother me, unless there are meant to be
advantages of using usx2y?
