Helping a friend with his newly acquired (used) A/G Leipzig (model) organ. Powers up, lighted draw knobs, c/a and pistons (thumb and toe) work, at least light up properly. Has MIDI in/out connectors. MIDI out to a MIDISport sends MIDI to the H/W computer using Auto Detect (okay so far).. Problem keys play an octave lower than they should. Keyboards are 8 X 8 matrix. Pedal board works as a 8 X 4 matrix. Can't get any output via (2) built-in power amps.Nothing smoked or apparently missing. Listening via Hauptwerk installed on my laptop with extension powered spkrs..See a small (plastic cased) relay between the power amp's output transistor's heat sinks that doesn't seem to do anything
Looks to be in good condition, just a little dusty inside. Probably early 90's vintage, as in early digital. Would like to use the original MIDI setup and, if possible, the original electronics in addition to Hauptwerk.
No hiss, hum, snap, crackle or pops from output or headphone jacks and then there's this manuals playing an 8' stop sounding an octave low as if it were a 16'. Haven't found a manual or any other (Leipzig) info on the net. As expected, Hauptwerk doesn't respond to stops, c/a or expression peds.
Ideas?
