trigger question & pro-2000 fun

2000-02-13 by J. Larry Hendry

I have spent a large portion of today exploring the vast capabilities of my
Kenton pro-2000 and getting it tweeked up for a multiple voice MOTM system
(I need more VCAs Paul).  As a part of the process, I realized that I can
control the amplitude of the trigger pulse, gate or whatever else assigned
to the aux outputs.  I have all my gates set for +  5 volts.  However, the
trigger is just a scaling thing rather than voltage.  So, I am about to
pull my scope out to measure the amplitude of the trigger pulse, and then
realized, "I don't know what it should be."

So, I have a generic trigger question and one specific to the Kenton
pro-2000.

The first one is easy.  What voltage is correct for a trigger pulse?  I
know gate signals seem to vary from 5 to 15 VDC, with 5 being appropriate
for MOTM.  What about those pesky triggers?  What is right for MOTM?  Do
other synth EGs require different voltage triggers?

The second question is only for pro-2000 users who have programmed more
than 2 voices from a pro-2000.  I have successfully programmed the third
voice from aux outputs, but can find no way to get a trigger out for the
third voice.  I can get the CV and gate, but no trigger (except the ones
for voice A or B).

Lastly, it seems that once I get my MOTM-800s modified to work with gate
only, the pro-2000 is capable of supporting 5 basic voices if you do not
need any extra aux voltages for anything.  Aux 1 through 6 can be assigned
for 3 more gates and 3 more V/oct outputs. Cool.  I have been having a
blast today with aux outputs 3 through 6 assigned to various controllers
and plugged here and there.  My expression pedal has turned into a quasi
wah-wah routed into that crazy 420 FM input.
