"these modules are the next in the "dot series." i'm ordering the first rev PCBs this week (one is done, the other just needs its jacks shifted around) and if they check out i'll get the front panels.

this is .MIX. it's a mixer with a transistor makeup gain stage copied from the Moog CP3, including the rail voltages (a regulator is used to provide the -6V rail).

there are no opamps in this thing at all, and it will be driven into distortion easily. alot of the tones on Redshift records are multiple oscillators being distorted by the CP3s.

the output attenuator is bipolar.

the .COM is a comparator/divider optimised for audio and based on the SH-101's suboctave circuit. a fourth output which ANDs the main output and the first suboctave is provided in addition to the original 3. the signal input is at the top and the other input jack is for voltage control of the threshold for PWM.

by "optimised for audio" what i mean is that its output swing isn't 0-5V, but -5V to 5V.

i might change the text from "threshold" to "pulse width". i don't know.

"what would i need this for?" you might ask, i would answer that maybe you want to use a filter as an oscillator, or perhaps you'd like suboctaves on your sawtooth oscillator."

BugBrand Weevil07 Prototype One-off Noise Synth

"BugBrand Weevil07 Prototype
This is a one-off prototype for the Weevil07 - you can see a YouTube vid of the actual unit here: [LINK]

Info on the Weevil07 is given here.
..although that doesn't give much detail! But there is a PDF instruction sheet here

Note that I changed the layout of the dials compared with the PDF document! The Low-Power dial is top-left on this proto unit whereas in production versions it was central in the bottom row.

There were a couple of changes between the Weevil06 and the Weevil07:
- I added a pulse-width control to the two oscillators taking the wave from 50/50 squarewave up to a narrow pulse
- and the filter was changed to a much more powerful version with resonance control
At that time I was experimenting with routed PCB front panels so this unit has.
Note that there are no LED indicators on this prototype, nor is there an internal mini-speaker as was found on many other Weevils.
This unit is housed in a compact and strong metal box with mono 1/4" jack output.


This comes with a fresh 9v battery.

korg prophecy with black keys and white leds


via this auction

"The keys have been painted flat black which is very sexy looking for a synth. White l.e.d.'s are intalled by the mod wheels and ribbon controller/3rd mod wheel and under the keys to give the keys back light and to create a mood in the studio or on stage. It's really incredible for performance b/c of all the 3 assignable mod wheels and the assignable ribbon controller and the programmable arpeggiator and the knobs on top."

I added a spunkytoofers label. Click on it below for more. You'll find details on this unit including video in a previous post as well as the auction of course. I also updated the Ebay store link on the right from d3park to spunkytoofers.

For all the burly dudes out there.

What's Synth Amp?

Update: a keytar would be cool.

moog taurus II synth

via this auction

"It's basically the same thing as a moog rogue, but without the keyboard.

This synth has a great moog sound and a beautiful filter, with the relatively rare (for a vintage moog) ability to sync the VCOs. It's very easy to use, and very hard to make sound bad. I've made up two special cables for the gate(positive) and CV(linear) ins, and these will be supplied with the synth. Then you can plug in any CV/gate source you have to drive it."

black korg poly 800 II synthesizer keytar blue l.e.d.s

via this auction

"All buttons and the pitch bender/joystick work perfect. The synthesizer has guitar pegs and guitar strap and can be run off C batteries and used as a keytar. Keys have been modified and painted black with blue l.e.d.'s under the keys to give it a really cool polished look. The l.e.d.'s kinda give the keys a blue backlit look. You will look awesome with this on stage or it would look great in a studio."
