I'm finishing my custom A-100 cabinet and installing all the modules in it.



I have problems with the MIDI Interface.

I built a home mad bus for the modules, which has all the +12/-12 + Volts,
and also rails for CV and GATE Signals



I have a A-190 connected but the A-190 doesn't show any activity if I press
a key on my MIDI Keyboard.



Also, If I press the GROUP, MENU buttons on the A-190 nothing happens.



Is it broken or am I doing something wrong Could it be a problem in the
power supply (I'm using computer power supplies at the moment, waiting to
buy a suitable one once all is finished.)



Please help me if you can..
