[sdiy] oberheim matrix6

[Nate Reeves]

how do test the voltages at J03 for the power board on the matrix 6?

i dont see any test pads with the voltages labeled on them....

i found 3 pads around the DAC, +12, -12, and ground....

i am getting close values close to those so that is good

i tested another connection by pressing the DVM probes onto the little  
metal "cubes" on the side of the connector end plugs (where the wires  
are crimped in)


is this the normal waY to area to test voltages coming off the power  
board?


i want to make sure all my voltages are correct before looking into  
anything else!

  i get power sometimes and i even got a patch to make sound!

  but when i switched to another patch, it didnt output any audio  
again.....B^(

how can i load the sysex into the unit?  just MIDI handshake and dump  
with sysex librarian or some such utility?

how can i upgrade my software if needed?

cheers
