Hi I have Roland AIRA TR-8 which seems very close to working with the ALSA driver . . . I'm guessing the driver may need some tweaking (an entry in usbquirks.h?). It is a drum machine with a sequencer and drum synthesiser. In addition to standard analogue audio out and MIDI out ports, it has a USB port for MIDI in/out and digital audio (mostly for input). It has 4 audio outputs and 14 audio inputs, the inputs are for sending each drum sound in for DSP on a separate channel. Its fixed to 96 kHz. The Roland AIRA are new devices (this year) and lots of fun so I'm sure they're worth a go for other users if there's a dev with enough time to spare :-) The recording is the most useful feature to get working (drum sounds into the computer). Thanks!
