Hi Michal, > http://www.evolution.co.uk/pub/manuals/mk-425c_449c_461c_advanced_use >r_guide.pdf thanks a bunch for your efforts! Unfortunately, it's only about how to set up the device to send GS sysex commands, not about the sysex format of the device itself. m-audio really makes a top secret about their sysex commands :( . Best regards ce
