I built jack and ssm (and rebuilt my 2.4.22 kernel with caps, lowlat,
preempt) and I'm having problems getting the plugin to work.
First, there was a function pointer type mismatch in the sample
rate change callback function, which I fixed. Now, recent cvs
ssm builds with jack-0.80.0 (well, for me... I could send my
patch...)
I get the jack plugin gui rect on the canvas of ssm without
problem, it does switch back and forth between detailed and
simple GUI.
When I have the jack plugin without connecting it to anything
and not attached to the jack server, output to the oss output
works fine, but when I tell the jack plugin to attach, I get
a buzz sound whose pitch is the same as the rate the Process
callback is being called; if I have a mixer before the output
plugin, the volume of the pitch is scaled by the volume sliders.
When I have any jack plugin input connected from any ssm plugin
output, -and- the plugin is attached to jackd -and- the jack
plugin's input is routed to an alsa output, I get a different-
sounding buzz that is also the same rate as the Process callback
invocations. This buzzing sound is -not- scaled by any volume
sliders in ssm.
At the moment, I'm not sure what to do... but I'm looking into
the possibility that the samples as represented by jack are
not of the same data type (-and- don't get converted) as the
samples as represented by ssm.
Comments? Help? :)

hi all - I'm trying to understand the concept of Jack Transport, so I can
understand what's not working, and what I'm just missing...
here's an example I crossing my fingers on, but figured wouldn't work: run
jack, run ardour, run rosegarden. set ardour to "jack transport master" and
rosegarden to "jack transport slave" - play ardour, hope that rosegarden
starts up - of course this didn't happen, but I can hope! :)
I knew it wouldn't happen, because the sync capabilities in both programs
aren't done, I know that part - but I was curious if it would try at least,
or what
but then it occurred to me that even with everything working, there may be
something more to do, perhaps with Jack (what? I dunno maybe
jackd --enablethedamntransport or something :) ) - so I thought I'd try and
find this out - and as always, I look around a bit, and if I don't start
finding mention of it pretty quick, I ask this list...

yeah yeah I'm workin' hard, sendin lotso questions - sorry if I yack too
much :)
Cheesetracker - maybe cool - can't tell - very unintuitive for me - are
there any tutorials, step by steps, how-to's, or demo/example files (the
last because if I can hear it do it's job with something already made I'll
start to understand really fast)

Hi All,
I'm considering buying a secondhand M-Audio Quattro. There are plenty of
them popping up on ebay all the time. The problem is I live in Australia
and the quattro uses an external power supply - does anyone know if a
Quattro bought in the US can be made to work on Australia's 240V mains
power - either through an adaptor or a different power supply?
Cheers,
- Adam

Hi once again all,
I have installed rezound (succesfully I hope! ). But it seems to hang if I try to use jaskd.
Here's what happens:
I fire up an xterm and type:
jackd -d alsa -d hw:0
Then I see this:
jackd 0.80.0
---notices---
jack compiled with System V SHM support
loading driver ..
hw:0|hw:0|1024|2|4800|nomon|swmeter|rt
open
starting engine
Then I fire up another xterm and type: rezound
the second I do that in the first xterm (jackd's) I see this:
alsa_pcm:xrun of at least 8.834msecs
Then (or at the same time) a dialog box pops up on the screen:
Choose port for output Chose 1
I choose: alsa_pcm:playback.1
and I click on ok (green check mark)
Then everything stops
when I get tired of waiting and ^c the rezound window, this pops up in the jackd term:
subgraph starting at rezound timed out (subgraph_with_fd=11, status = 1086326156, state = Triggered)
subgraph starting at rezound timed out (subgraph_with_fd = 11, status = 1088326156, state = Triggered)
I am using the latest rezound :0.8.3beta
and jack is 0.80.0
alsa is version 9.rc2
sblive 5.1
850mHz stick of Celery
256mBram
lfs-4.0 distro
Hope this is enough info =)
thanks again for al the help guys

Hi all,
I have been able to record guitar parts in audacity. It weems to work real fine so far. However I still can't get anything to come through stompboxes2 other than a hissing sound. I guess it just wasn't meant to be.
What I intended to do with stompboxes2 was to just play through them at first, with the option of recording through them later. The way I usually record guitars is to tun them through an amp, and mike the amp, the mike going to a mixer, or more preferable the br-008.
I'm not too heartbroken over the stompboxes2 being broken because I still have the br-008, and I can always record through audacity ( pretty good ladspa effects there too!).
Thanks all who tried to help.
This is one "Kick Butt" forum!
later,
james

Hi guys, I don't konw if you can help me out here, but I could not
find anywhere to ask this, so here I go.
I recently downloaded an compiled OpenAL on my system via CVS. Every
thing was OK, except when I tried to compile with support for my
SB-Live! card (emu10k1 chipset, running through ALSA). I went trhough
the instructions and the package did configure correctly, here's what I
asked of it:
./configure --help (just to see what options did I have)
./configure --enable-arch-asm=yes --enable-alsa=yes --enable-sdl=yes
--enable-emu10k1=yes --enable-vorbis=yes --enable-smpeg=yes\
--enable-capture=yes
make
Here's the error I get:

Sorry if some of the messages are misspelled, since the output was
originally in Spanish I had to translate the best I could. Any ideas?
Thanks!

Low Latency patch: http://www.zip.com.au/~akpm/linux/schedlat.html
Preemptive patch: http://www.tech9.net/rml/linux/
Capabilities: It's only four lines, just do it manually. JACK website has the info.
