Lady and Gents,

For those of you who may own some of this gear, I have published a sort list
of extremely easy modifications for some of them which can be seen by going
to:

http://www.allegrobikes.com/synth.html

Click on 'Son of Frankensynth", scroll down the page until you see a text
link marked 'modifications', click there.

All list functional descriptions, show faceplate pictures of the mods and
schematics (diagrams to some of you - you know who you are!).  As a
precaution I did not include the schematic of the entire circuit, but only
the mods for each.

And the mods  are:

1) Adding a Range Switch and End-Of-Cycle Pulse out to an Analogue Systems
ADSR

2) Adding a VC input for the delay time of an Analgue Systems Gate Delay

3) Adding a Pulse Wave output to a Doepfer LFO (will work for any LFO that
does not have such a jack).

4)  VC input for a DOD Flanger (this won't be up for a couple of weeks)

Soon, I will be posting descriptions (and some schematics) of my homebrew
modules,  incuding my sequencer, voltage adder, voltage inverter, noise,
AND/NAND gate, and the world's all time WORST design:  my CEM 3374 based LFO
with programmable pulse outputs (allows you to start/stop the pulsing via
buttons or trigger inputs).  So, if any of that interests you,  keep your
eyes on the site as I am making updates for these real real soon.

As Chuck would say "chow',

best,

P
