hello! I bought a new midi controller Hercules DJ Console RMX2. This device uses MIDI protocol to send commands to Mixxx(not Bulk as vendor`s previous devices ). I connect the device to the PC, start Mixxx 1.11(compiled from trunk), the device is detected as midi-compatible, but there is no layout for this controller. I tryed to do this manuality, using Learning Wizard, but the mapping I got is not full. Nevertheless when I tryed to play on it in Mixxx, I got kernel panic(I use Archlinux x86_64, linux kernel 3.6.10). When I reboot my laptop, and try to work ith Mixxx again, so Kernel panic may be appear sometimes again. But there is also the following problem. It seems that buildin high quality sound card doesn`t support. I use ALSA (v.1.0.25) to work with audio devices in my system. The sound card is detected by UDEV and described in the system. It is detected as "Rmx2". It seems it uses Xmos DSP chip to work with audio. When I try to admine the sound card I get the error from ALSAMIXER: "Protocol error". I tryed to search the solving of that problem, I found that problem may be connected with such item that there is no full support of UAC2 in alsa. The problem may be resolved by adding such support in alsa-driver or may be firmware from Xmos(if used chip is Xmos made really) to alsa-firmware. Anyway if somebody can help me (it seems not only me) please, give your recommendetions how to resolve the problem with the soundcard and may be anybody of developers has mapping for RMX2 . I don`t want to use Windows and such software as Traktor and etc, I prefer quickly working linux OS and optimized for my laptop fresh Mixxx release from the sources. I even don`t know where I can write about this problem to and get support. Please help me.(((
My Laptop CPU: Turion64x2 TL-62, 2GB RAM, VPU: Radeon 2600Pro 512mb, build in Audio Card Realtec ALC268.
DJ midi-controller: Hercules DJ Console RMX2 with buildin audio card(it seems on the base of Xmos chip)
Software: Archlinux x86-64, stock 3.6.10 and manually compiled 3.7.1 kernels, ALSA 1.0.25
None of us have an RMX2 (yet). It's good to hear that it's a standard MIDI device but unfortunately we don't have the expertise to remotely debug your ALSA issue. I think maybe you should join the #alsa channel on Freenode IRC and request help there or maybe email the ALSA mailing lists.
