[Brent Busby] > Is there anything you can do on Linux to transmit a sysex file more slowly? > I'm not sure, but I think it may help if the data wasn't coming in so fast. sysex files being raw data dumps and ALSA devices being accessible through a raw file interface, this works for me: #! /usr/bin/env python import time,sys midi = open(sys.argv[1],'w') data = sys.stdin.read() for c in data[:-1]: midi.write(c) midi.flush() # sleep 2 seconds after EOX, 1 ms otherwise time.sleep (c == "\xf7" and 2 or .001) midi.write(data[-1]) # EOF $ cat file.syx | theabovescript.py /dev/snd/midiCxDy Obviously, midiCxDy needs to be replaced with the proper device path, x and y being card number and subdevice, and you may need or want to adjust the delay constants. Some devices need extra time to process complete sysex bulks before being ready for the next so an extra delay is triggered by interspersed EOX markers. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
