[LAU] Mackie C4 & ESI RoMI/O II

Hello. I'd like to take a stab at spying the protocol between the Mackie C4 and the Mackie "C4 Commander" control software. The plan is to put my Linux laptop between a Winmac running C4 Commander and the C4, start a MIDI capture and try to upload a known .c4i layout to the C4. ____________ _______________ ________ | | | | | | | OUT |--->| IN1----> OUT1 |--->| IN | | Winmac | | Linux | | C4 | | IN |<---| OUT2 <--- IN2 |<---| OUT | |____________| |_______________| |________| I need a small, light, 2-input, 2-output MIDI USB interface. Does anyone have experience with the ESI RoMI/O II ? -- André Majorel http://www.teaser.fr/~amajorel/
