i think i gave some info in another treath on this forum. anyway the great Tablehooter will take you by the hand : http://weltenschule.de/TableHooters/Casio_CT-410V.html (CT-410V is simmilar to mt400v) i recomment the arpeggiator mod, and also the enveloppe mod.... and individual outs... first thing to do-in my opinion- is to put a (polarity) diode at the dc inlet. o yes and the bass decay/cut off/reso trimpot adjust... anyways.. very wicked keyboardsynth. one of the best casio's around.
