The Rockband 2 Drum controller is a wireless velocity sensitive percussive instrument that is cheaper than its competitors (~$90 retail) and arguably as good as many medium quality drum controllers. With this software and a Linux computer, you can use the controller to compose your own music in real time.

I plan to do an analysis of the drum quality, but for now please download the midi files I have created to see for yourself if the below midi files generated by an impromptu outdoor session make sense.


libusb is a cross-platform userland driver abstraction library that uses kernel hooks to allow drivers to be written that do not require actual kernel drivers. In this way I able to create a driver without modifying your kernel with experimental code.

The following libusb functions are used to make this possible:
I plan to explain how they are used in a future version.

ALSA is a Linux platform specific driver library for audio (PCM and MIDI). My program becomes a client that emulates a MIDI sequencer.

The following ALSA functions are used to make this possible:
I plan to explain how they are used in a future version.

Instead of a while loop or some other high latency, low performance method, I found that it is possible to use libusb to call events when the usb device sends them. This makes my system as low latency as a userland system can get without setting up a real-time kernel (although I suspect that it will work if you are using a real-time kernel). Let me know if you'd like to test this or improve upon it.


$ make
$ cat /proc/usb/devices
$ ls -l /dev/usbdev*
$ ./rbdrum2 &
$ sleep 2
$ timidity -iA -B2,8 -Os -EFreverb=0 &
$ sleep 2
$ aconnect -lio
$ aconnect 128:0 129:0

Linux MIDI is an interesting beast, I wish you the best of luck.
