I guess we could add the option of a slew limiter for each ouput. If you want, populate the
board and wire you jacks to a differnt set of ouputs. That will add 4 more pots and
possibly 4 more jacks if you want both.
At this point we are up to 12 knobs, 19 jacks, 6 LEDs, three 5 pin DIN connectors and a
DB9 connector.
With 1/4" connectors, that is like half a 19 "rack. Same with Frac-Rac, a very big faceplate.
Then if you add a LCD display somewhere...
Any more stuff and the faceplate will be so expensive it will be too expensive for students
and beginning hobbiests.
For those who want to begin laying out faceplates, the faceplate component list is:
Jacks:
1 v/oct in 1-4
Variable CV in 1-4
CV out 1-4
Run Pulse in
Stop Pulse in
Speech out jack
Gate out jack
Trig out jack
Gate in jack
Trig in jack = 19
Pushbuttons:
Run / Stop = 2
Knobs:
CV offset 1-4
CV attenuator 1-4
Ouput slew 1-4 = 12
5 pin DIN:
MIDI in
MIDI out
DIN in or out = 3
DB9 for programing interface
LEDs:
CV indicators 1-4
Run / Stop LEDs = 6 total
Who is going to volunteer to do layouts in .fpd fromat?
One for MOTM and one for Frac-Rac. That will give us some idea of PC board dimensions
to work with.
I think we can use the Metalbox style 1900H knobs and Alpha pots for Frac-Rac.
The jack spacing should accept either Switchcraft (Blacet) or 16PJ135 (Wiard) jacks.
The 16PJ135 jacks wire up very neatly because of the ground tangs being in-line.
The knurled nuts are designed to be assembled with fingernails, so that is one less tool
you need.
