Figure 13 - Corrected CV Input Logic, Preferred Method, Front Side of Main Board
Behavior
An internal pitch CV source (MIDImplant CV 1 out) is connected to the CV header. The internal CV source
is the default source, and may be defeated by introduction of an alternative CV to the KBD CV Output
panel jack. If no internal CV source exists, a shorting jumper is placed on the header, to normal the KBD
CV bus to 0V, and prevent VCO motorboating.
Gate Connection
The MIDImplant gate connection is much simpler than the CV connection. Just bring the GATE 1 output
of the MIDImplant to the Gate header in the EG section. From here, the signal goes to the tip-switched
contact of the Gate jack.
Behavior
When the Gate Select switch is in the up position, the MIDImplant will be the default gate source, and
may be defeated by introducing an alternate gate signal to the gate jack. Either signal will be processed
by the Gate Booster.
Do not connect anything to the Trig header.
Suggested MIDImplant Mounting
My preferred method to support the MIDImplant is to build a small receiver from strip-board. You will
need ten lanes, and there are no lane cuts. The receiver is cut from the corner of a prototype strip board,
so as to include a screw hole. You can also drill a screw hole so long as you
don’t drill through any of the
ten lanes. The receiver board has a ten point female pin header, and 2P Molex type disconnect headers,
in this case using IDC termination. A ten-point male pin header stick is soldered to the MIDImplant. See
the picture.
