[linux-audio-user] rosegarden-4-1.0: can't seem to get any MIDI out ...

Hello ... (as an aside, please count me in as another Slackware-10.2 user, installing packages that don't ship with Slackware from source; I've been off the list for a while, but just browsed the recent archives and spotted that thread while looking for a solution to what follows ...) After my partially crippled music workstation workstation finally stopped booting altogether, I finally replaced it about a month ago (in fact, the hardware itself was replaced just about exactly a month ago, though I salvaged the audio interface from the previous system). The system is an AMD Athlon64, with a Cirrus Logic CS 4624 sound card ("Hercules Fortissimo Game Surround"), and an onboard ATI SB400 AC'97 Audio Controller. It seems that the ATI sound interface may be better than the CS 4624 for some things, though it doesn't appear to have any MIDI support, which the CS 4624 does, and which I consider quite important for my purposes. Drivers for both sound devices are compiled into a custom monolithic kernel. I haven't decided yet whether I'm going to try using them together (for example to provide additional outputs while processing sound files and mixing), or whether I'll use one in favour of the other, but whichever I do, I'm going to need to to use the CS46xx card for MIDI input and output. I recently installed Rosegarden-4-1.0, after having last tried Rosegarden in late 2003 (rosegarden-4.0.9.1), and previously having successfully used Rosegarden-2.1 to some extent. Before I go on, I have to take a moment to say thank you to the folks who worked on that (and frankly on the couple dozen or so other audio applications I've installed that are turning this system into a very respectable music workstation: from Audacity and LinuxSampler, to Ardour and JAMin, and all the support applications, gui frontends, and libraries that make them all tick). You guys have (all!) done really great work. Now the problem I'm having, I imagine is due more to my own lack of understanding than to any failure in the software or (I hope) an error in installation. Most things I use seem to be working fine: I can control LinuxSampler (and FLUIDSynth, with which I've also tested Rosegarden) from a MIDI keyboard plugged into the computer's MIDI input (through a MIDI patchbay, but it isn't configured to apply any sort of filtering on the MIDI stream). I can play MIDI files with aplaymidi through a synthesizer plugged into the computer's MIDI output (through the same MIDI patchbay). However, I can't seem to get any MIDI output from Rosegarden, either through the softsynths (LinuxSampler or FLUIDsynth) or out the computer's MIDI out port. I've tried various configurations with JACK, but still no progress. Can someone suggest where I should be looking for more information about this? I'll certainly provide more information if I've overlooked anything important. I've not tried Rosegarden's audio support (yet), though I was relieved to find that it seems to import Rosegarden-2.x files apparently flawlessly. Audio out works fine from other applications I've tried, though (Ardour, Audacity, FluidSynth and LinuxSampler), so I'm not expecting to have any problems with this function in Rosegarden. Any help with my MIDI problem would be greatly appreciated ... -- ---------------------------------------------------------------------- Sylvain Robitaille syl(a)alcor.concordia.ca Major in Electroacoustic Studies Concordia University Faculty of Fine Arts / Music Department Montreal, Quebec, Canada ----------------------------------------------------------------------
