Neither does /dev/snd/midiC0D0. If by "Rosegarden-2", you mean the package named "rosegarden", version 2.1pl3-1, that's present in stable, testing, and unstable . . .I can't tell you what you need to do to make it work. However, I *can* tell you that you almost certainly don't want to be running that package. That Rosegarden, v.2, is dead upstream, has a lousy interface, and is very feature-poor. Instead, I encourage you to use what until recently was called "Rosegarden4" (and has the Debian package name of "rosegarden4") but is now simply called "Rosegarden" by its developers (who appear to be pretending that earlier incarnations didn't exist). The current Rosegarden is under *very* active development, has a great interface, and is feature-rich -- so much so that it's getting close to what you can do with Cubase. For more on the current incarnation of Rosegarden, see http://www.rosegardenmusic.com/ . . .I strongly suspect it's what you want to be using at this point. Note that it requires JACK for full functionality. But if you're doing serious audio work on Linux, you need JACK anyway. But I definitely haven't had any problems getting the current Rosegarden to use the right device. It's just worked. > Audacity: /dev/dsp doesn't work for recording. Audacity does not yet use ALSA natively. Instead, it's designed to use OSS, which means it has to go through ALSA's OSS emulation capability. This is sometimes problematic; I don't know why. I've noticed, though, that Audacity sometimes has problems with other running programs that want to talk to /dev/dsp. Run Audacity from the command line and see what errors you get. If on startup you see something like . . . } PaHost_OpenStream: could not open /dev/dsp for O_RDWR } PaHost_OpenStream: ERROR - result = -10000 } PaHost_OpenStream: could not open /dev/dsp for O_RDONLY } PaHost_OpenStream: ERROR - result = -10000 . . .my suspicion is that some other program you're running is hanging on to /dev/dsp in a way that's making it hard for Audacity to use. That said, I don't really use Audacity much anymore (I've moved on to Ardour for editing -- even stuff for which it's overkill, since that helps me learn how to use it), so someone else may be better equipped to help you here than I am. You might also check on the linux-audio-user and alsa-user mailing lists/archives. -c -- Chris Metzler cmetzler@speakeasy.snip-me.net (remove "snip-me." to email) "As a child I understood how to give; I have forgotten this grace since I have become civilized." - Chief Luther Standing Bear
