That could be. Haven't had an SB card around for a long while - I think
the last one was an SB Live! 512 PCI, I never used that one with Linux.
It worked just fine with OS/2 and Windows95 ...

Hmmm, have used nothing but ASUS mobos here for several years, and never
had any sound problems using either on-board sound or add-on sound cards
of various kinds (no M-Audio ones, though). They just worked, without
any special trickery.

I've used Wacom tablets for over 10 years. Quite delightful, and it
would be a very new space as far as a music instrument interface goes.
But it wouldn't work like any of the instruments that humans have
developed centuries of expertise playing.
I hope someday to have the money for a Theremin. Humans have been
developing eye-hand control and dexterity for a million+ years - might
as well play to human strengths!

A digital glove idea would be interesting, especially if they get to the
point where you can wear one and play without any feeling that it's
there, coming between your skin and the instrument.
Then you'd need a "digital bow" to capture the variations in bowing
speed, angle, pressure and tension of the bow. Then you feed all that
into a synthesizer able to adjust the synthesized sound appropriately
(note by note and WITHIN individual notes) - and you have a synthesizer
that could be as expressive as a violin.
Then we can tackle the process of matching the expressiveness of a
well-played Blues Harp! ;-)

Hi peeps,
I've been away from the list for months now, busy with work and our
baby, but I've decided to start making more of an effort to see what
people are up to and also to do something myself.
Here's what I'm working on. The bass is just not going right for me
at all. I wish I had a bass guitar. And the ability to play it.
This is kinda the intro - although it won't be particularly
lyrically complex, it will have more than just this phrase repeated
throughout. Excuse my singing, it's my first go.

I've probably missed lots of other people's great stuff. If anyone
has any recommendations, please pass them on!

Any KeyKit users out there? I'm not familiar with this ALSA virmidi
business, but I'm getting the following error trying to run KeyKit
using the virmidi device:
[paul@boon doc]$ key
ALSA lib rawmidi.c:283:(snd_rawmidi_open_noupdate) Unknown RawMidi hw:1,0
Unable to open MIDI device 'hw:1,0', snd_rawmidi_open failed: err=No
such file or directory
key_alsa: conf.c:3075: snd_config_update_free: Assertion
`update->count > 0 && update->finfo' failed.
Here are the steps that led me to this error. First, I installed the
virmidi module:
[paul@boon doc]$ sudo /sbin/modprobe snd-virmidi
Then I check for the card number:
[paul@boon doc]$ cat /proc/asound/cards
0 [M66 ]: ICE1712 - M Audio Delta 66
M Audio Delta 66 at 0xc000, irq 19
1 [VirMIDI ]: VirMIDI - VirMIDI
Virtual MIDI Card 1
Card 1, no surprises. Check the device file:
[paul@boon doc]$ ll /dev/snd/midiC1*
crw------- 1 paul root 116, 40 Aug 23 22:10 /dev/snd/midiC1D0
crw------- 1 paul root 116, 41 Aug 23 22:10 /dev/snd/midiC1D1
crw------- 1 paul root 116, 42 Aug 23 22:10 /dev/snd/midiC1D2
crw------- 1 paul root 116, 43 Aug 23 22:10 /dev/snd/midiC1D3
Ok, sure. Set the environment variable telling KeyKit which device to use:
[paul@boon doc]$ export ALSA_RAWMIDI_DEVICE=hw:1,0
Then I ran the "key" command, and got the error above.
What am I doing wrong here? This is on FC5/PlanetCCRMA.
[paul@boon doc]$ rpm -qa | grep alsa
alsaplayer-0.99.76-2.rhfc5.ccrma

I'm now at the point where I can play midi files, and I have a midi
keyboard connected and can play sounds to and from that.
Timidity is rubbish, frankly, so I'm using fluidsynth, which works fine.
However, for some reason I can't get qsynth to work.
Qsynth1: Failed to create the MIDI driver (alsa_seq). No MIDI input will
be available.
No matter what settings I try, it always fails. The only useful message
I ever got was for alsa_raw, when it said that the device didn't exist.
For some reason I have /dev/snd/midiC1D0, but not /dev/snd/midiC0D0. So
I temporarily symlinked them, but that didn't help- it wasn't
complaining about a missing device any more, but it still couldn't
create the midi driver and still wouldn't tell me why not.
Also, both fluidsynth and timidity are too slow. Midi events are routed
around instantly (tested with vkeybd and the keyboard I have plugged
in), but there is a delay in playing anything sent to fluidsynth or
timidity- about half a second or so. I've tried running fluidsynth with
nice -9, but that just makes everything else less responsive and doesn't
really decrease the delay at all. Any suggestions? If I was to buy a
decent sound card with a hardware synth would this fix it? Would I be
able to load enough soundfonts into it? What about a pcmcia/cardbus
version for my laptop?
Thanks
Simon
Hi Everyone,
I'm looking for an inexpensive sound card for my laptop that will record
in stereo. My Dell D600 is crippled in that they didn't hook up both
wires, even though the chip used is a stereo chip. I want ALSA drivers.
USB would be best, but a firewire or PCMCIA card would also work. I
looked at the IndigoI/O but it requires hotplug, and Ubuntu has moved
away from the hotplug system. Please be as specific as possible. I
have found that manufacturers often change the chipsets even though the
card name is retained.
Thanks,
Rob

I have Ubuntu Studio and a Delta 1010 card... I'm up against a problem and I
am stumped, so I'm hoping someone can help.
The card is recognized, at least jackd can see it and start up just fine. It
shows hw:1 as the M-Audio Delta 1010LT and hw1.0 as the ICE1712 Multi. It
can start using qjackctl using either.
The Envy24 mixer also starts and appears to work fine.
Ardour (the goal) also starts and can map tracks to the various inputs.
Here's the problem. No sound. At all. Nothing. I tried all of the inputs and
the envy24 mixer sees nothing, Ardour sees nothing. I used the patchbay to
patch one of the inputs to one of the outputs and piped my mp3 player into
it - and got nothing on the output.
It's like the PCI interface to the card is just fine and the control backend
works, but the audio section is uninitialized or something.
Has anyone had any luck with this. FWIW, I installed the card after Ubuntu
was installed, so I don't know if the installation scripts would have done
anything differently had the card been there at installation.
Any help would be SO greatly appreciated...
Thanks in advance
Eric

Dear James,
Good to have you back! Your music is sounding great as ever. good singing
too. I just wondered if you are still using cheesetracker? You should check
out aldrin if you have not tried it already..
http://trac.zeitherrschaft.org/aldrin/
A buzz-tracker clone for Linux.. I have been hacking on it over the last
couple of months or so (it is written in Python), but it was written by
Leonard Ritter who remains as lead programmer for the project. I can
heartily recommend it (despite my efforts at "improvement")!
The other thing.. congrats on your baby! I had a look at your website. Was
he really born on Christmas day? That is the same as our daughter, although
she was born in 2003.. Amazing Christmas present huh?
All the best,
James
