Okay, so I picked up a VFX that had supposedly been repaired and had the keyboard problem and some other stuff fixed, and it’s been a huge pain. I ended up REfixing the keyboard connection, replacing a slider, and fixing up a bunch of random careless reassembly mistakes.
At this point it plays nicely, keyboard is all good, display is good, controls are good, and it’s just great until I try to load in sounds from cartridge or sysex.
If I drop in a cart and try to select sounds, I get garbled patch names, blank patch names, and just odd behavior. They usually don’t actually play. Same with sysex-- I can dump a bank to it, but the memory gets filled with random junk. You can see some parts of the patch names, but it’s like maybe a third of the data actually gets there.
Resetting memory works, though. The presets are there and play nicely.
Does anyone have any idea what’s up here? I assume there’s a bad trace I didn’t spot or an IC that’s hosed. I’m not afraid to bring out the desoldering gun and replace parts if I need to.
Thanks.
