Hello Jan, I've been busy for a while, but I will soon release a new version of the driver, and patches to mixxx as well as the midi mapping file for the DM2. I am currently able to use mixxx with the DM2, it works good, some small bugs remain, and there are some featurs missing...
Status: - wheels are woring in playback and pause mode - middle button and buttons A, B to sync left/right - buttons A and B for headphones left/right - middle button and wheels for speed control Problems: - the wheels generate signed midi control messages, and mixxx understands only unsinged midi - I think this is wrong and wrote a patch for it, just to test it - I gonna try other midi devices and see what messages they produce - I gonna try other midi apps with my DM2 driver - then I'll ask on the mailing list, if maybe this should be changed in mixxx, if I'm sure my device is producing correct messages :) Please try the newest version on: http://prophet.homelinux.org/usbdm2/ -> usbdm2-2007-12-04.tar.gz > I'm not sure whether you're following the mixxx-devel list.

I looked into your > driver and have tried it, but setting the LEDs doesn't seem to work. the problem is, that the DM2 is a non standard USB device, since it uses USB BULK transfer (for setting the LEDs) and it is a low-speed usb device. This is not compilant to the USB standard, and the linux kernel does not allow to send BULK messages to low-speed USB devices. The newest version of the patch includes a patch to the linux kernel, making the LEDs working happily :) > First of all, my aim is to build a minimal DM2 driver which will give > access to all the functions of the DM2 via MIDI, and that includes the > LEDs. Is there any standard way to transmit LED settings by MIDI? why do you want to create a new driver ? just send me patches ! I'm planning to use the LEDs as vu-meter in mixxx using a midi control object (0: no LED, 16: one LED, 32: two LEDs, ...). As well as some note on/note off events for accessing the LEDs directely. regards andré -- Andre Roth | <[EMAIL PROTECTED]> GPG: FADF988E| 0959 4D7C F8ED DF4B 90A6 CF71 9EDF 52D1 FADF 988E
