Hi Newly built box, running bootloader 1.2 and mios 1.9c with midibox64 2.4 I know many are going to say its a connection or wiring problem. But ive checked the connections and wiring 4 times with a beep meter. All unused pins are grounded. When i plug in the box to the pc, its quite, i get only one upload request(normal).\ Once i turn the pot, then the jitter starts, in midi-ox in the port activity window, input ports 1-16 flash at random but very fast. How can this be, if unused pins are ground and i checked the ground with the beep meter, it beeps when i touch the pins and ground on the other end of the board. Im only using one pot to debug this. When the pot is in the middle and i use the beep meter on its center leg and on a grounded pin, it wont beep. If i put the pot value to min, the meter beeps. So wiring checks out. Just a reminder, I dont know if this is normal, but the jitter only starts once i turn the pot. So if i put turn on the box, it comes on as i get the one upload request, then it sits quite. Once I turn the pot, its endless jitter, all different midi events. So wiring/connection fault or something else? Just abit more info,when i connect the ain module and ground the proper pins and so on, same as above, only, the jitter comes from potwhich i turn. So if i turn only one pot, the jitter comes from there, if i continue to turn other pots, the jitter comes from thos aswell. This is according to the port activity monitor in midi-ox. The jitter is only reverb depth. Ive tried the box with fruity loops. The jitters cause some bad play back. But if i turn the box off and on while im in fruity loops, it works. I set the pot to control the volume. Works perfect. Then I tried traktor dj studio. The box works fine, no problems and I dont need to off/on the box. Even when I use the learn function, more than once, it all seems fine. So i removed the entire ain module and im using one pot to check if its a problem with the ain or core module. Seems like a core problem. The software only works with the ain module in, but when i use the unmuxed one pot with the software, i get jitter problems. Offcourse, when i removed the ain module and connected one pot directly to the core, i ground the proper pins.
