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.
