<< SO I have this Sequential Circuits Tom Drum Machine.  I just got a new 
power supply for it,  The unit will turn on a perform all functions except 
the drum pads do not trigger any sounds.  So I squeezed in the contemporary 
cartridge and still nothing, no sound.  I am ssuming my power supply is 
working(otherwise unit would not turn on)  So then I thought is was my 
outputs, but the Metronome function works great and I hear a steady click.  
So I opened the unit up everything is there, no missing chips no cut bridges 
and no fried parts.  Has anybody ever had a similar problem?  Any ideas? >>

Have you tried playing the sounds from MIDI?  Maybe the machine has a MIDI 
"Local On/Off" function that needs to be toggled.  You could also try sending 
it some MIDI Volume control messages (controller #7 at a value of 127) - 
maybe someone previously the set volume to zero.
