Hi. I use jackd as follows: /usr/bin/jackd -v -R -P70 -dalsa -r48000 -p128 -n2 -D -Chw:0 -Phw:0 -Xraw Here's my output from alsa-info script: http://www.alsa-project.org/db/?f=8b1149c838d952854b79008a7a9b1980bd3ba0ff I notice that when I record MIDI from my vDrums, the playback is never quite right. It doesn't matter what sequencer (e.g. qtractor, rosegarden, etc.) I use to play a midi file. I tried a little experiment: 0) record some midi of my drumming 1) use qtractor to send MIDI through my Midiman 1x1 USB midi interface to the vDrum brain 2) use ardour to record the audio output of the vDrum brain 3) repeat steps 1 & 2 4) compare the waveforms of the resulting audio tracks I get notes that vary between the files by 30-40 ms. Incidentally, if I bypass alsa and create a WAV file with timidity, it's spot-on perfect. So I don't know if alsa sequencer is just broken or if there's some configuration/tuning that I could do to improve this. Any input appreciated (helpful input preferred :) Thanks, Steve ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
