"This is a simple vid that i slapped together to show you how to get some good glitchy speak and spell sounds without having to circuit bend it."

DotCom, MFM and Doepfer MAQ16/3

YouTube via attorks
"Rhythm sequence with an 8 step sequence on row 1 of the MAQ16/3. Row 3 controls the dynamics of row 1 which results in a switch on/off for each step. The Synthesizers.com Modular on top produces the high RM type sound, the MFM below produces the low noisy sound."

JH. Subtle Chorus

via JH on AH:
"Hi, just wanted to give you a quick update of my upcoming (fall 2008) "Subtle Chorus" PCB project, which, among other things, will be able to emulate a Dimension D, (using original ICs and all), plus "Dim T" (Same topology but with two 20-stage phasers instead of BBDs), plus generic true-stereo, dual-BBD chorus. Depending on what configuration you want, this will use one, or up to four PCBs. (Dim D emulation needs two PCBs.)

The "Subtle Chorus" is a variable project consisting of 3 different PCBs that can be combined for various functions.

a.. You can build a rather simple, true-stereo, dual-BBD Chorus with voltage controlled Chorus Rate and voltage controlled Chorus Depth, using a single PCB.
b.. You can emulate the famous "Dimension D" (Trademark of Roland / Boss) sound with it's unique filtering and presets, using two PCBs, the "Dim D" (You even have the choice between vintage HA1457W opamps, or more common TL071 / TL072 opamps.)
c.. You can build a similar effect that uses 20-pole all pass filters instead of BBDs, using three PCBs, the "Dim T".
d.. And you can build an overkill effect device that allows to choose between the Dim D and Dim T effect, using 4 PCBs, the "Dim TD" version. So far, the BBD board design is finished; main board will be the next.

Documentation is here:
http://www.jhaible.de/subtle_chorus/jh_subtle_chorus.html

The BBD board needs 2 x MN3007 and 2 x MN3101. These are quite easy to get, compared to other vintage BBDs. The Dim T version doesn't need any BBDs, of course...

Forgot to mention:
BBD board also needs 2 x NE570 (or NE571, or SA571) companders."

The Solar Module MIDI Demo ElectroKraft.com

YouTube via orphiusflux. via sendling
"This is a demo of some of the MIDI functions of the Solar Module. The Solar Module is an 8 bit synth and a MIDI controller. You can plu the Solar Module into any MIDI device, such as a drum machine, keyboard, synth module, or PC/Mac MIDI software. Anything that accepts MIDI input!

ElectroKraft.com"

Solar Module by ElectroKraft.com
"The Solar Module is a combination MIDI controller and 8 Bit synthesizer.

Moving your hand above the photocell sensor, the Solar Module behaves like a Theremin. MIDI output and synth output, it's 2 instruments in one.

Notice how the synth can sound very much like an 80's video game? That's called the 8 bit sound.

Enjoy.

via electro-music.com where you will find more info and other people's designs of this DIY sequencer by Ken Stone's Catgirl Synth.

"An 8-step analogue sequencer/programmer, newly-built, not quite working 100% as yet. It's an iteration of Ken Stone's excellent design, and a set of PCBs is available here, if you want to build one yourself. Recommended, but not for a first electro-music DIY project, there's a lot of wiring up involved."
