Hi All:
I'm an analog muso (30 years+) and a Linux user (5 years+), but am totally
new to doing audio on Linux (or any other OS).
I've got heaps of stuff installed on a laptop running Fedora 3 (ALSA,
JACK, Hydrogen, Muse, Rosegarden, SooperLooper,
CheeseTracker and a lot more) but unfortunately most of it doesn't work
yet. This is almost certainly because I don't
understand ALSA and/or JACK properly. Also MIDI, I'm really in the dark as
to what it is, what it does and how it works.
I know sound works because I can play .wav samples in XMMS. Without
starting JACK, Hydrogen runs and plays demos just
fine as well.
But as for Muse, Rosegarden, SooperLooper and CheeseTracker, no go. With
SooperLooper and CheeseTracker, I can load
samples/instruments and "play" patterns and everything appears to work (I
can see things such as level meters etc moving
as expected) except no sound ever emanates from the speakers.
For example, SooperLooper. First I create a virtual soundcard (hw:1) and
start JACK with 'jackd -d alsa'. JACK starts
ands runs fine. Then I start SooperLooper, load a sample (.wav file) and
off it goes apparently just fine but without
sound.
I have tried to connect SooperLooper and CheeseTracker (both on port 128)
to JACK as follows but to no effect. The examples below show what I did
for SooperLooper
What am I doing wrong? I know the answer will probably be simple!
TIA, Mick

Hi Mick,
You appear to be running Jack in a terminal? Give qjackctl a try.
It will give you a visual patch bay where you can hook the app up to
the sound card. I suspect that the audio output of your app is not
driving the sound card.
In a terminal I think you could do some jack command, like
jack_lsp, to see what's hooked to what, but QJC is much more useful.
Good luck,
Mark

Hi Mick,

Yes, most of my Linux experience has been configuring servers by fiddling
on the command line, or writing web code. Old habits die hard!
I grabbed Qjackctl and it sure makes a difference. I'm now getting sound
out of CheeseTracker and Rosegarden. The fact that some of these
programs connect themselves is pretty cool.
Rosegarden looks like a phenomenal piece of work, that is what I've been
looking for I think. Big learning curve with all the MIDI stuff, but
that's what life is for!
I'm also looking for a lighter "live" solution for playing with samples
etc (bass and percussion and effects) along with "real" musos.
Great stuff.
Thanks all for the tips

linuxsampler (with its frontend qsampler) does wavetablesynthesis
based on the famous gig-format of GigaSampler.
zynaddsubfx does synthesis with oscillators/etc.
fluidsynth (gui: qsynth) does wavetablesynthesis using the
sf2-soundfonts created by / for creative's soundblaster chips.
aeolus is an organ synth that sound like a real organ and even better
than some real organs thanks to the great work of fons adriansen.
hydrogen does drumloops and drum synthesis. PD, AMS, OmSynth and many
more do synthesis with pluggable modules...
You should also take a look at jackit.sf.net, they also list software
that uses jack...

Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklich
verhindern könnte, würde ich mir noch heute einen Stapel Brenner und
einen Sack Rohlinge kaufen.

For ALSA and Jack, I would like to suggest the following:

There is a MIDI how-to here, among other things:

Hopt that helps!
