MOTM

That's one of my 'always-used' modules.  The power switch is lighted 
and controls a 2U panel on the rear that has AC mains in and switched 
AC mains out.  That way I can control all of my cabinets from a
single 
switch.  I also added DC out with fuses on these power panels for 
powering remote devices if needed.  The headphone amp is nice and the 
cable tester was built after frustration with a batch of bad cables.  
It tests continuity for low ohms and shorts.

I have designed or borrowd and modified a number of circuits to add
to 
my modules.  Other modules in the parent directory include:

Spring reverb, 3 input mixer, output attenuator, and an A-440 
reference generator.  This is always used as I like a bit of spring 
reverb on all my patches.  The A-440 is also nice and often used.

Mixer-Comparator-FWR.  This is basically the Richard Brewster module 
but I added a Full Wave Rectifier with either AC or DC coupling.  I 
use the comparator a lot and the FWR is nice for sharpening up some 
mellow sounds.

Dual LED voltage monitor.  This allows me to visually see waveforms 
such as LFOs and envelopes.  It has dual channels and is similar to 
the one that Scott Juskiw also designed.

Analogic is my favorite.  I wanted a OR, AND, NOR, NAND circuit for 
gates and designed a 3 input analog version.  It will take the
greater 
or lesser of three signals and also has an invertor.  For logic
levels 
it functions as an OR or AND with an invertor.  For analog or audio 
signals the output follows the greater or lesser voltage.  Mixing two 
distinct waveforms like a sine and saw at slightly off frequencies 
outputs some distinctive sounds.

Quantizer and lag.  This is a dual quantizer followed by a lag 
circuit.  It is similar to the Arp-style quantizer and works quite 
nicely.

Tape Output.  This is a level convertor for -10 dB outputs and inputs 
for my analog reel to reel.  It includes a polarity reverse as my 
Otari outputs are opposite sense from the inputs.  It also includes a 
mixer between line out and line in with a feedback control so I can 
easily do tape delays and echoes.

Ribbon interface.  This is a repackaged PAiA MIDI2CV with an analog 
offset and mixer for the Kurzweil Expressionmate ribbon.

Attenuators are just three 100K potentiometers for attenuation.  Also 
nice for driving -10 dB levels.

Output is a dual VCA and output level control for driving my Carver 
power amp.  It has remote power so my single switch also controls the 
power amp.  The VCA is typically driven with my MOTM-850 pedal 
interface so I have an overall pedal volume.

The Sound Canvas is a repackaged SC-7 full GM synth that I can drive 
with the MIDI out from my PSIM.  I really like this module and the 
PSIM combination.

The level shift module is also used with my PSIM to be able to
convert 
the inputs and outputs to +/- 5 volt levels.

The last is my keyboard interface which is really just multiples and 
power designed to interface with the Hendry 822 VC Switcher and I use 
it with my Arp 3604 CV keyboard.

Enjoy. - Dave
