I bought a used MTM Radio Music and it functioned a bit strange. The CV in for Reset did not respond to any type of control voltage. The CV start did not seem to respond either. The only CV in that seems to respond is the station. The start position Knob also does not seem to respond and I can't select the banks holding the reset button down.
I updated the firmware to the 2017.2 hex file on a teensy 3.2 board and loaded the standard settings.txt. Unfortunately I still get the same behaviour.
Could it be a build issue and where would I be best approaching it. The only odd solder points are for the pins on the teensy. The other solder work on the 2 boards looks professionally done.
Any advice as to where I should best probe with a multimeter be mich appreciated.
