I use OpenBSD to record music (audio and midi, combined), with the following hardware: - a Roland XV-2020 syth module (umidi) - a Behringer BCF-2000 control surface (umidi) - a Studiologic SL-900 midi keyboard - a ESI Julia card (envy) - a 1.8GHz Pentium 4 with 256MB of RAM - an analog mixer with mic-preamp and reverb I use midish as the main sequencer. MIDI parts (ie the syth) are recorded/played as simple tracks in midish. Audio tracks are simple wav files handled by an aucat slave process controlled by midish. I.e. midish issues all start/stop/relocate commands while sndiod keeps the whole thing synchronized using MTC/MMC. Additionnaly, I create a dedicated "mixer" track in midish where I record volume automation for the audio tracks played with aucat. Once everything sounds ok, I record the mix of synth tracks into a single wav file and I mix all audio tracks together to get the final mix into a single wav file that I compress with oggenc or lame. I don't use softsynths very often, but if I do, I use a midi thru box (additional -M option to sndiod) to make it look like a midi device so midish can use it. I record the softsynth output with "-mmon" option of sndiod. I don't edit & tweak the music off-line too much since I consider that I should at least be able to properly play the music I'm trying to record... To summarize: # the server setup sndiod_flags="-M -z480 -b960 -frsnd/0 -r48000 -sdefault -tslave -smmc" # command to play/record audio tracks aucat -fsnd/0.mmc -qmidithru/0 -tslave -r48000 -i track1.wav ... # midish configuration dnew 0 "rmidi:3" rw # synth dnew 1 "rmidi:2" ro # keyboard dnew 2 "rmidi:1" rw # control surface dnew 3 "midithru/0" wo # slave aucat wav player dnew 4 "snd/0" rw # sndiod dmtcrx 4 # use dev. 4 as MTC clock source Ah.. last point, not necessary, but I build sndiod with COPTS='-DADATA_BITS=24' to get end-to-end 24-bit precision.
