I have been looking over Ken Stone's neat version of Electronotes VCO
Option #1. I was thinking how it could be put behind a MOTM style
panel. As Ken's note says, "This is one of those PCBs than can be
assembled in a number of different ways to suit the builder's panel
space or "maximum knobs" requirements." With this panel version the
waveshapers (1 chip) are omitted in favor of packing a nice VCO into a
1U panel space. The features are somewhat like the MOTM-310 VCO, but
there are two different frequency control inputs, both attenuated. The
FM input can be switched between the exponential FM DC input and the
linear FM AC input. One of the Serge-like reversible attenuators is
used for the CV input. Finally, one input jack serves a dual purpose,
being switched between SYNC and PWM. This panel is almost identical in
layout to my Mixer-Comparator, with 3 pots, two switches, and 6 jacks.
Not sure when I may get around to building these (I want two), but I'm
pretty keen on the concept. Just wanted to share my idea.

I finally finished building the combination dual Little LFO, dual Little
EG module. It came out quite well. I plan to take photos and post
them. The most unusual aspect of the panel design is the placement of
LEDs and switches to the lower right corner of each pot. These are not
labelled on the panel with the benefit that you can choose different
placements. Each module (LFO or EG) has two pots, one switch and one
LED. On the EG the switch selects AD/AR output. I had planned to use
the LFO switch for TRI/SQU output selection, but changed it to a range
switch.
This panel idea lets you have 4 of these modules in a 2U panel. I gave
up the SQU output on the LFO and the separate AD and AR outputs on the EG.
With the Little LFOs on the top there is no clearance problem with
mounting rails, because of the smaller board size. If the EG boards
were put on top, there would be a clearance problem and the boards would
have to be milled down a tad. If you put switches in the lowest
positions (which I did), they have to operate side-to-side and there is
a tight fit next to the jack. The switch has to be installed before the
jack. It's not an optimal location for switches, so near to the jacks,
but it works and I opted over putting LEDs there, so low on the panel.
The extra PC pads for power jumpering makes it easy to daisy-chain power
across all four modules, so you only need one power connector.
The only problem with my original panel FPD is that it had 3/8" holes
for the pots. The Oakley pots have a slightly larger diameter. I
updated the FPD file for 13/32" hole size, which is what I drilled out to.
If you are planning to get Little LFOs, check out my panel design. You
can edit it for four of them. You can choose SYNC inputs vs. SQU
outputs, maybe having two of each. You only need to edit labels. The
same could be done for 4 EGs, with the caveat about top clearance.

I've been looking pretty hard at the Cynthia Sawtooth Animator myself.
I actually built one of the original Electronotes Multiphase Waveform
Animators for my 1980's era synth. Would appreciate more comments on
your experience converting the Cynthina module to MOTM panel format.

I have done only one (quad low pass gate). The PCB fit quite nicely
on one of my 3 pot long brackets. I ran the PCB deep. Now that I
have my modular brackets I might have oriented the PCb up and down.
But, the process was fairly easy as all the pots and such are planned
for off board mounting, like CGS stuff.

hey everyone
to find my panel and module waiting for
me.
have not started actual
dissassembly/reassembly
or even power up. but when i do i'll let you know. the quad low pass gate was a breeze to convert. i have a stock pile of
larry's
mounting bracets which i use for
everything.
a note for people cynthia's module has 4 lfo outs
for
each module - she chose to have the last two mixed
into one.
you cuold if you wanted add 2 more jacks for 2 more
lfo outs.
i went ahead with her idea - but if you look at my
panel youll
see theres plenty of space to add two more jacks if
you want.
all the best to everyone

Sounds fabulous Richard, can you explain the patch? Is it just a saw into MPWA?
> File : /Richard Brewster Designs/Mpwa.mp3
2004-01-31 by Richard Brewster
The main idea of "waveform animation" is to impart dynamism to the sound
that is independent of pitch. The MPWA accomplishes this by sawtooth
phase shifting, which sounds something like pulse width modulation but
different because the harmonic series is different for sawtooths. (I
also built a complex pulse modulator from Electronotes, all those years
ago.) Here is an MP3 I just made, a 2-minute excerpt from a very
ancient recording over 20 years ago on cassette tape. The recording
quality leaves much to be desired, but it will serve to get the idea
across. This was done with one VCO, droning on the same pitch
throughout -- yes I was a rabid minimalist and the piece is 30 minutes
long -- and driving the Multiphase Waveform Animator (Lester Ludwig
design) with its sawtooth. The MPWA contained eight LFOs and eight
sawtooth phase shifters. It had one input and one output and had no
controls. The output was a mix of the original plus all eight phase
shifts. In this patch result was processed through a Low Pass VCF with
a moderate Q setting. There is some modulation of the stereo field. I
can't remember all the details. Most of the richess of the sound comes
from the animation.
The MPWA would track any frequency changes of the VCO, but the LFO
frequencies were fixed. Read Mark Barton's discussion about the MPWA on
http://www.cyndustries.com/
A problem with the MPWA was that it worked best with low frequencies,
such as in my example MP3. Cynthia's Sawtooth Animator's LFOs can track
the incoming frequency. "Low input frequencies mean slower LFOs and
high frequencies mean faster LFOs - all of them." And the LFO
frequencies can be voltage controlled. Other features include LFO
outputs (nice for making correlated filter patches), and a pulse
output. All intriguing features, to be sure!.
One question I have is about the input level being 5V p-p, which I
gather is Modcan standard for audio signals. No doubt it will not be
difficult to modify the input for 10V p-p MOTM sawtooths. Likewise I
wonder if the output level needs boosting as well. I am very interested
to see how Dave Wright's conversion goes.

I got around to taking some pictures today of one of my recent
projects: 2 Oakley Little LFOs and 2 Oakley Little EGs in one 2U
panel. There are two pictures of the completed module, one front and
one back. This worked out nicely and demonstrated another possible
switch placement: to the lower right of a pot. It's not an optimal
spot, because you tend to hit the switch when adjusting the pot. But if
you really need to cram a panel full, such a placement can help. All
switches are in the same relative position to the pot, but the EG
switches (selecting AD/AR output) are horizontally positioned.

scott/richard/group:
i just put an mouser order in for some switchcraft jacks and the needed
pots for the sawtooth animator so it will be prob be a week till I'll have
it up
and running - but you all will be the first to know. i hadn't even thought
about
the 5v/10v situation - all vcos in my system except my thomas henry 566 and
darkstar are 10v - i'll let you know about that.
scott how dare you - i'm trying to drive myself homeless onto the streets
buying parts
for my modular - how dare you help me sell records! ;) - any folks on the
west coast we'll be hitting the road in march - and yes i am bringing my
modular.
i know i shouldnt but i am. why not come out and see it in person
dave wright
ps - if you folks want to hear some of the demos i've done with alot of
motm/cgs/
oakley/cyndustries and blacet modules exclusivly (i.e. no midi, no
multitracking)
check out
http://www.carrionsound.com/gallery/sounds/sounds.htm you can surf around
there
to find more info on the modules in my system if you care. you may have
designed some
of them.or their panels ;)

This is a 1U panel for four passive devices: 1 potentiometer
(Resistor), 1 Capacitor (1 of 11 values, selected by a rotary switch), 1
Vactrol, and 1 Diode. Note that all three terminals of the pot are
available, with the BOTTOM terminal normalized to ground. This allows
it to be used as a 2-terminal rheostat, as for example in a low-pass
filter configuration with the capacitor. (Signal into Wiper, with
Bottom tied to one end of Capacitor through a multiple which provides
the output.) Both ends of Capacitor are normally connected to ground.
Each of the four devices can be used independently. And they can be
patched together to make various high and low-pass filters. The Vactrol
provides a voltage-controlled resistor. (I am thinking to add a 470 ohm
series resistor to the Vactrol LED to limit current.) I had room for
two more jacks, so I included a Diode.
I think I will make one of these and try it out. Unfortunately the FPD
panel costs $60 US!

works fine for me.
i went to -
http://launch.groups.yahoo.com/group/ModularSynthPanels/files/
opened Richard's folder, and then downloaded passives.fpd. depending
on the browser this can be accomplished either by option-click, or
control-click then Save File As..., or right-click then Save as...
etc.
clicking on the passives.fpd link, rather than downloading it,
results in a blank screen in Safari, but quite possibly utter chaos
on other browser configurations.

I have a couple of questions about tolerances on FracRack panels
I want to send to Schafer.
1.
What tolerance is typically specified for width, holes, etc.?
2.
How much smaller should I make the board to allow assembly?
I saw some specs. on a FracRack panel:
Deburr outside edges, do not round corners
Light grain, black anodize
tolerances: +/- 0.010 in
Holes +/- 0.005 in
Are these reasonable?
Should I just design the panel to be 0.010 inches smaller in
width?
Thanks

WOW, looks fantastic. I'm a bit unclear as to whether some of the
green circles are for LEDs, or switches, or pushbuttons along the left
edge (RANDOM INPUT down through CLOCK THRU RATE). Also, I noticed that
the CLOCK THRU and CLOCK IN labels are centered above the jack, but
EXT LOAD, EXT RANGE, and RANDOM INPUT are not. Is that because some
are switches and some are LEDs?

Yeah, that's just the CAD I send to the metal guys (dimensions on
another layer), so green is .25" and tiger print is .375". Doesn't
really help, huh?
The Ext Load, Range and Random Input have associated switches (LED for
Random Input, I think). I figured that legending is more obvious than
the on/off legending. I'm thinking the switched would be left/ right,
or _towards_ the jack if you want that jack enabled. Is that OK w/
everyone? I can add on/ off if you want. I still haven't decided
whether to do MOTM boxes for the standalone switches or not. I think
not in this case, as it would make a graphic mess of it.

Thanks for the clarification. I prefer switches that go up/down, not
left/right. I generally assume (thinking digitally) HIGH = UP = ON,
LOW = DOWN = OFF. I don't think you need to labels, or boxes, for the
switches, I think that would just make it look cluttered. I say leave
it as is.

i agree. i too think they look fine as is and the boxes arent needed.
gates & triggers
would it make more sense to swap the positions of the GATE and TRIGGER outputs so the associated hi-low led indicator sits next to the GATE output instead?

Is the CLOCK THRU jack simply connected to the CLOCK IN jack? If so,
this jack could instead be used as an output for shift register B
(after the INVERT switch), call it SRB OUT. This would allow cascading
the output from one Klee to the input of another Klee (connect KIee #1
SRB OUT to Klee #2 RANDOM INPUT) to achieve 32 step sequences. Does
anybody else think this is a good idea? If you are worried about
connecting a CMOS output to a jack, there is an unused op-amp that
could be used as a buffer.
Even if you don't change the legend on the panel, I will likely wire
mine up this way. I came up with a dozen Klee modifications, but
implementing them all would require a ridiculous amount of hardware
changes (I would have to make all new PCBs) and a panel 3 times the
size of the one you've got. I think I'll stick with the official Klee
for now.

I like your idea. That's what I'll do on mine, I think. I think I'll
keep all legending non-mod, though, as I've found that most people
don't do mods.
Super-Klee? Wow, and I thought this one was confusing enough! : )

I have some photos on my web site www.xmission.com/~dingebre
I’d be happy to cobble some video together. I have the PCB art
available if you want it for the A440/beat freq/Headphone amp, too.
I think I might have an extra PCB, too.
I’ll try to get some video up on the web site tonight.

Hello, got a question for you all.
I am trying to draw out a panel in inkscape for planning purposes and was wondering if anyone had some kind of graphics library they could share with me. For example I'm looking for pictures of knobs, slider caps, jacks, switches, led's etc, that I can use to help plan this thing out. I'm a COMPLETE newbie when it comes to graphic design so I am totally stumbling around as I'm trying to piece this together. I am going to DIY this panel myself and am using a mac with no dual boot stuff loaded - so no FPE. Also it would help if pictures were to scale with dimensions included (or part numbers so I can look up the dimensions :) I've been able to pull some pictures off the internet however, as I can't figure out how to trim images & use fills appropriately I am
getting this crazy patchwork quilt looking panel that is doing nothing but driving me crazy!
Seriously, any help/pointers would be greatly appreciated.

I’d be happy to cobble some video together. I have the PCB art available if you want it for the A440/beat freq/Headphone amp, too.
I think I might have an extra PCB, too.
I’ll try to get some video up on the web site tonight.

I've made some changes to my JH Interpolating Scanner(s) and have put a new FPD file up on my website. There was an empty spot on my previous panel (what was I thinking?) which I've filled in with an LFO output jack. I also tackled the thorny issue of how to use MOTM-standard Lumex LEDs and get them bright enough to actually see them. The solution isn't simple but it works great.
Look here for full details including schematic, 3U FPD file and lots of construction photos.
