Hi, I just tested the Trigger Finger (link below) by m-audio at the local dealer's shop, and it worked immediately when I plugged it in thanks to the snd_usb_audio module. Thanks to all devels! The only thing I miss is the possibility to make backups. m-audio has a tool called Enigma (available for Mac OS and Windows) to make backups of the settings (and even programming the device). The device itself has no option to make it send a sysex dump of its memory contents to the computer. I asked m-audio for the request string to do a backup, but I was told that this is only possible using the Enigma software and the special usb-audio-driver by m-audio. I doubt that. Can anyone provide request strings for any evolution/midiman/m-audio products (UC33, m-audio keyboards)? If so, I could likely derive the requests for the Trigger Finger from it. Even Enigma (nomen est omen?) can handle a large scale of m-audio devices, and I guess that all devices work in a similar manner internally. Any hint, even to a PDF doc or similar which contains sysex documentation for any similar device would be helpful. Thanks in advance, ce Product Link: http://www.thomann.de/thoiw2_maudio_trigger_finger_midi_drumcontroller_prodinfo.html
