Speaking of which...
Can the tech guys here enlighten me regarding the program selector
switches? I _guess_ the four switches end up at the same IC which opens
the selected path... My hihat card works great upon startup if I stay
with the factory preset. If I choose anything else it turns weird.
Sometimes it plays some odd form of mix of all the presets but mostly
it's just a lame and dull sound coming out. The LEDs either light up all
or none. After fiften minutes or so it works as it should. It might be a
bad soldering joint since heat might help...
I dug out the schematics and looking at that crappy copy it looks as if
the IC2 (14556) might be the culprit. IC1 is a 4013 btw. Any input from
you soldering guys?
