Just wondering if this is a common problem... upon switching banks of faders, sometimes a random fader will not move to the appropriate position, but the others will. MIOS 1.7 MBLC 1.4 1.6A 12V PSU... maybe not enough current for (2x) 40x2 LED backlit displays, and 8 panasonic MF's? Could that be the problem? (though the problem happens even when only 3 faders are moving at once) BTW, I've tried Soundblaster Vibra 128 midiport, as well as midisport 2x2 (yeah I know the midisport is not good) Anyway, at least with touch mode 2 the faders won't send any dodgy data while they are in the wrong spot! ...Thanks, from Steve
