Division 6 Filtare SEIII for Eurorack

via Division 6
"The Filtare SEIII is a multimode, state-variable voltage-controlled filter that gives you low-pass, band-pass and high-pass outputs which are all simultaneously available. It also includes a notch output which allows you to change the balance between low-pass and high-pass. The SEIII uses discrete components but is based on SSM2040 architechture, giving you a very musical sounding filter. There are CV inputs for frequency and notch balance. The 1 V/O CV input for frequency tracks over several octaves so you can have the filter follow what you're playing on the keyboard or just crank up the resonance and use it as a sine-wave oscillator.

Specifications:
* Modes: LP, BP, HP
* All modes are 4-Pole (24dB/Octave)
* Notch: Change balance between LP and HP (total drop with balance at center is 3.4dB)
* Power supply: +/12 VDC
* Width: 8HP

Inputs:
* CV (for frequency control): 1V/O fixed
* CV (for frequency control): Adjustable
* CV (for notch balance)
* Audio

Outputs:
* Low-Pass
* Band-Pass
* High-Pass
* Notch

Controls:
* Frequency
* Resonance
* CV Level (frequency)
* Notch Balance"

Note: the big news is this is Division 6's first eurorack module!!!

SFH DIY Polyphonic Synthesizer

This one in via André. You can find full details and more images on Elektronik-Projekte in German. The following is a translation of part of the description in Googlish:

"This synthesizer is my largest project so far. I have built good 3 years out (1989-1992) and in fact the device has never been properly finished. The basic functions are, however, almost completely, ie You can elicit this synth sounds absolutely fantastic.
The programming of sounds is a bit cumbersome: About the control keyboard 48 parameters can be set by the oscillator, filter, affecting the amplifier and the envelopes. Here are some pots were really served well, but that would have been too costly.

Here are a few technical details are the synthesizer:
* Keypad: 4 octaves (not velocity sensitive)
* Tone Generation: 6x DCO, 6x DCA, DCF 1x, 1x Noise
* Polyphony: 6-coherent or 3-consistent when using 2 DCO per voice
* 4 FX buttons: pitch up, pitch down, modulation, chord memory
* Operation over 12 buttons and 4-digit LED display
* Direct Sound for an additional keyboard with 32 keys
* Interfaces: MIDI In, MIDI Out, MIDI Through, Tape, Audio Out, Headphone "

Cross modulation patch - Hardcore modular - Synthesizers.com + Yusynth


YouTube via Thalassa77
"Just a patch that I've been experiment with this afternoon. Two VCOs that they are modulating each other. A LFO is used as clock signal. The result is weird sounds that when you speed up the time sounds like techno-hardcore ( more or less ).

Sumarizing ... just me having fun with the synth. No midi or keyboard are involved on this patch is a self-running patch."

Clock 2 CV


YouTube via wonkythomas
"Main Clock goes to Odd Divider (D)Mux, /2 goes to Even Div. (D)Mux. Control inputs are from /16 & /32 of the main clock.

2 outs from each of the Div. Muxes are fed into mixers, combined & drive a VCOs CV input.

In addition to straight clock divisions being mixed together, 2 of the demultiplexed Odd Divisions are being OR'd together, this combination is being slewed by an Oakley Lag & a VCS with the former controlling timbre & the latter being mixed into the Pitch CVs.. this is where the bendy notes come from.

The timbral modulation is just the Volatage Controlled Waveform of the Blacet VCO."

Clock 2 Seq

"Same as before, but now Odd & Even Divider (D)Muxes are being controlled by seperate sets of divisions of the main clock & the CV created by mixing the various pulses together is being quantized by a Miniwave.

Its much like a Binary Zone... but with a differant feel because of the odd divisions.

The cam. is sitting in front of the breadboarded output / LED buffers for the Odd Divisions; the green & red are straight off the demultiplexer, the purple is the OR of two of the other outputs."

Clock Seq CV Reset

" Another VCO is added, both are getting the same Quantized Pitch CV.

After about 30secs I don't alter the mix of pulses, but, there is one important addition to this patch, in fact one of my favourite techniques at the moment.

I tap off the Pitch CV & feed that into a 2 Bit ADC which takes a 0-10V signal & outputs two digital signals depending on the voltage. These two digital outs control the Reset Inputs on the Divider (D)Mux modules. So:

CV = 0V; neither Divider is reset,
CV = ~2.5V; the Even Divider is reset,
CV = ~5V; the Odd Divider is reset,
CV = ~7.5V & Both are reset.

After about 45secs into this vid I start altering the Offset voltage for the ADC, this voltage is combined with the incoming CV (our mixed down & quantized clock pulses) so the CV sequence changes the CV sequence = hours of fun for the whole family... so long as your family likes poppers & wigging out to squiggly voltages XD"

Clock Seq End Drum

"On & On... bass drum being triggered by the VCS End Out Pulse.

Shows the CV to Digital module in action; the Red & Green LEDs which flash more or less depending on whats happening with the sequence. Everything interacts with everything now. Change one of the amounts of Divided / Multiplexed / DeMultiplexed clocks being mixed into the quantizer & the divisions change, which changes what gets mixed in... happy mediums are arriveed at, iterations occur, wobble & drum are interlinked....

.... sometimes it might even sound musical!"
