tried swapping round the diode and the optocoupler, no change. the caps should be fine, i have no way of checking the crystal, but being as it came with the kit i shouldn't have any reason to think that its damaged or wrong.

well i don't have a pic programmer, and i couldn't find instructions on how to make one for an 18f452. all the other tests indicated everything was normal, voltages, midi works on computer end, proper componets and soldering is fine. So the only thing i can think of is the pic needing reprogramming.

well, i hooked it back up and tried to upload a few things with MIOS studio but it didn't work, the only message that comes from the midibox is "system reset" on power on, i don't acctually get any other response from it. I'm pretty sure regardless of having mios on it or not its supposed to send an upload request on power on. Any suggestions?

ok, i tried uploading something and it failed, perhaps just a bad midi connection, will recheck and try again. Thanks

I ordered all the parts for a Midibox SID and after putting them together, all i get is a steady 5v from the output of the PIC, which is labeled "BSL v1.2B mios v1.9D". i checked all the powered pins, and they're all fine. any suggestions?
