I have read some device manuals, and it seems that it'll be a midisport 8x8. I already have installed the firmware loader (thanks to the author, BTW ;-), and even if the handling on linux is a bit difficult, I liked the midisport due to the fact that it can act as a real merge bay in offline mode. The only thing that still keeps me without the device is the price - I have no problem paying lots of money for synths, but a MIDI device is somehow a piece of hardware I do not like to spend money for ;-) .
