The virtual thing	And the real one

Notes:

I have added a trimmer on the panel to set the input level,. It is an option like to add more controls to the fast ADC input, another input jack summed with the first one, attenuator or bias pots pots, etc, etc ...

MIDI DIN plugs :

There is no MIDI plugs on the real panel because MIDI is internaly wired into my modular cabinet... It is also possible to use only one DIN plug for In and Out : Wire a normal MIDI IN on pins 4&5 and a MIDI OUT wire to pins 1&3 ...2 still go to ground. Make an Y wire the same way, to adapt to normal two plugs MIDI I/Os.
