I've got three A-190-2 (MIDI->CV converters) chained together so that the out from one goes to the 'in' on the other. I'm using the PCB pins for MIDI IN/OUT to do this as per the manual.

I've set the key mode to 'stack', and set all the 190-2's so that they receive on midi channel 1.

The three units all work, and as I press keys, the appropriate 190-2 triggers (ie the third unit triggers if 2 keys are already held down).

However, while the pitch on the first unit is fine (its connected to a A110), on the second and third units the pitch is 2 or 3 octaves lower. In fact its just clicks.

Any ideas what I've done wrong? For the three A110 modules, the range and tune settings are all identical.
