ED... Yes i dissable MIDi program change messages.
Everything appears good, the JV don't interrupt the power...
whats going on ??
What kind off Midi message can break off the power in the JV ??

Im controlling a Motif ES rack and the JV with M-Audio Pro88 thru 2408 MK2..

This problem happend since i bought the M audio, before that, im controlling with Kurzweill and all works perfect.
You thing is a MIDI problem ?? Maybe M-AUDIO transmit some message to the JV ?

Thanks !!
