Troubleshooting
First apply power to the box, then connect a midi keyboard. When you press a key or move a
pitchbend/modulation wheel, the LED should flicker. If this is not happening, you either have:
1.
The midi wires around the wrong way
2.
The power wires around the wrong way
3.
The 6N183 optocoupler IC installed the wrong way around
Midi is working but there is no audio?
–
check the wires on the audio socket, maybe you have them
around the wrong way?
If its still not working, check the wires AGAIN. Check that all IC’s are the
right way around. If its still not
working, remove the knobs and remove the nuts from the switches so the PCB can come out. Double
check the PCB for dry joints. Look for things that you forgot to solder. Look for blobs of solder you
accidentally dropped on
the board that is “bridging” pads.
