I had a fully functioning, cased Midibox Seq V4. Everything was fine for about a week, but then I had a weird message pop up.
Everything is fully functional, until I plug in any midi device to any of the out ports. Then, I'll press play, and the step 1 led turns red, and I get a message on the LCD screen that reads "Midi Timeout Error". I've re-soldered both IO Modules, and even picked up a new set of midi IO boards. I soldered one together with all new parts, without the activity indicator LED section (Only the collection of resistors 2 diodes that run the In and out circuit), and still have the same error.
What's weirder, is that when I make the same circuit from the schematic on a breadboard, and just plug it into only MidiOut1, everything works great.
has anyone else experienced anything similar to this problem? All my solder joints on the new module are good, and with the output portion, I'm only dealing with 3 components. It's very strange.
