But still no sound. OK, I did a "cat /proc/asound/card0/wavetableD1" and discovered that the soundfont wasn't actually loading! I hadn't installed the package containing sfxload, so my call to it was failing, and I didn't realize it...

[linux-audio-user] Debian 2.6.14 alsa problems

by David Baron

Still cannot get this to play. Kernel boots up fine loading of any alsa fails with a bunch of undefined symbols. I am using neither udev nor devfs (no longer in kernel)--based on an old knoppix hdinstall, upgraded to Debian Sid. Kernels through 2.6.11 worked fine. 2.6.12 --mpu401 fails, 2.6.14 alsa audio fails. Fun.

[linux-audio-user] keeping alsa stable

by Atte André Jensen

Hi I thinking about how to make the audio part of my debian/unstable as stable (stable as in "not affected by apt-get upgrades in a bad way") as possible. I'm using the realtime kernel from demudi which should provide ost of alsa. And csound5 is compiled in different dirs (not installed) so I can switch version simply by changing a symlink. To get that out of the equation I run directly on top of alsa without jack. Now what I'd like to know is how much of alsa is updated through apt-get update from unstable? And how key are these parts to my simple setup? Are there ways to keep the system more stable than what I have? Thanks in advance for any pointers... -- peace, love & harmony Atte http://www.atte.dk

Hi Steve, Arabesque is a miniature delight. I love the bitter-sweet, minor/major harmonies. Thanks for sharing some more of your work.

But still no sound. It's probably something ridiculously simple, since I'm new to this... Are there any utilities to check Midi status, etc. that would be helpful in troubleshooting this?

By hacking together, i assume you mean by using http://tranzport.sourceforge.net/ ? Can I suggest you a route to go about? Don't send keyboard events to ardour. That will make the software unreliable (focus changes, tranzport "dies"). There are better options: Ardour responds to MTC/MMC. You can make a piece of software which listens to the tranzport events, translates them into MTC/MMC and sends them to a alsa sequencer port. This means that you can use the tranzport to control ardour, any other software which uses MTC/MMC, _and_ all external equipment who support it. Of course, this way you can't get all the cool information like metering, track names, etc. which you would get with better ardour integration. Otoh, this way you get yourself acquainted with the device and it will help you when the time comes to write the "real" driver for ardour. Sampo

Just to verify: you loaded a valid soundfont into the wavetable synth, and you're sure you're sending the MIDI command sequence to the wavetable synth? -c

[linux-audio-user] Frontier Design Tranzport working

by Arthur Choung

Hello, I just got a Frontier Design Tranzport and after a little bit of work, I finally got it working with Linux. I was wondering if anyone was interested in knowing how it works and what not. If so, I will put together some documentation and source code and post it somewhere. -Art <arthur_choung(a)yahoo.com> Product Link: http://frontierdesign.com/Products/TranzPort __________________________________ Yahoo!

[linux-audio-user] Multi-port MIDI interface

by Ben Loftis

What are the good multi-port MIDI interface available for Linux? The ALSA matrix was some help, but without reading every entry it is hard to decipher how many ports each device has. So far I have found the M-Audio MidiSport 8x8. Is that the biggest/best interface available? Thanks in advance, Ben Loftis http://www.harrisonconsoles.com http://www.studiooutfitters.com

Re: Re: [linux-audio-user] Debian 2.6.14 alsa problems

Hello, I'm having exactly the same problem with my emu10k1 (SBLive 5.1) sound card. All the MIDI programs I try seem to _think_ they're working... but still no sound! (Other audio works fine, though.) I have used the SuSE and Fedora distros, but same thing.
