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
