I like this idea! If there is a single multi-pin connector
coming off of a panel it could provide power for the remote control box
as well as carry the return signals to the system, whatever they may
be. Then the panel could have several 1/4" jacks on it so one could
patch the remote control signals to modules. This would work great for
me.

In the last few days I made ( with Paul's assistance) an
external box running on a 9v battery that has one momentary switch and
one pot. It has 2 1/4" jacks for output. One is a fixed +5v trigger and
the other is variable via the pot. There is also a high/low switch that
sets the width of the pot from either 0-2v or 0-5v. The pot is activated
by the momentary as well. This assures that the battery does not drain
unless the momentary is pressed. It also allows for some cool effects. I
had a sustained vocal sound going through the VCA modulated by the LFO
for a very fast 1/8th note stuttering type tremolo. By connecting the
variable output of my box into the 1V/oct jack on the LFO I was able to
slow down the the LFO to 1/4 notes, triplets or whatever and then let go
of the momentary and slide right back to the 1/8th notes! This may seem
rudimentary to some but it was very cool to me. It is nice to do this
from a remote so you are not tied down to keyboard controllers or the
front panel. You can sit in the sweet spot of your monitoring system and
go crazy.


I would also like to experiment with larger swings of
control voltages. I found that, in the same scenario as above, if the
LFO is running slow the +5V swing does not speed up the LFO as much as I
would like. Also when controlling filter cutoff points it would be nice
to go from very low to very high. I am looking for extreme sounds here.
Any ideas? Negative voltages too.


So I definitely cast my vote for a controller panel with a
multi-pin connector. In that way there is only one cable extending to
the controller box (very neat) and power from the system can be used (no
batteries to change). This cable could be standardized MOTM pin out but
could be used by various people for their particular needs ( Joysticks,
Triggers, Variable pots etc.)
