I forgot to tell you that I also have the +5V on my custom bus.

 

I have used a 7805 Voltage Regulator and managed to get the current to
exactly +5.08 Volts

 

Now the A190 sends some strange CV to the VCOs, (like a LFO set to a down
ramp)

The "clock" and the "gate" LEDs are always on. If I press a note on the MIDI
Keyboard nothing happens.

 

Pressing the Group or Menu buttons seems to have no effect.

 

What can be causing this problem? Does the +12 and -12 Volts need to be very
precise like the +5V?

 

I hope the Interface is not broken.
