"Dual Low Pass Gate - pretty standard except it uses the black box vactrol method seen in the Shat-noir Phaser and Noiro-ze VCF/VCA. DG analogue switches are used for changing between filter and gate modes."
Dual Low Pass Gate - pretty standard except it uses the black box vactrol method seen in the Shat-noir Phaser and Noiro-ze VCF/VCA. DG analogue switches are used for changing between filter and gate modes.
"This module uses the same blackbox technique as the Shat-noir Phaser.
The VCF is based on the Steiner diode VCF but this one uses LDRs rather than diodes and a CV control system to suit. The nice thing about this filter is you can feed different signals to the LP, BP & HP inputs then surf between them with your CV, quite different from regular filters.
The VCA is really there to use up a spare op amp and is based on the Korg PS3100 VCA, works very well for what it is.
"The core of the Shat-noir phaser is based on classic LDR based phaser designs, notably the Carlin, Compact Phasing A, Morely Phaser and ADA final Phase. The CV drive is an anti-log circuit, it works a little differently as both the CV and phase pots must be adjusted to find the sweet spots. The In2 pot is 0 at centre, the incoming signal is inverted below that. it is intended as a feedback input for one of the stage outputs, but shove in whatever you want of course.
Please note the build pictures below when constructing to make the box fairly light-proof. A little bit of leakage does not seem to matter much but you could add a bit of black silastic sealant around the edges if you really want to. When soldering the connector pins, use the SIP connectors, jumped across 1 or 2 pins (see pics) to ensure they are nicely perpendicular to the PCB. When soldering the PCB to PCB connectors, I press lightly on the PCB to help keep the connectors tight against the board.
The PCBs are 2mm thick with black soldermask to prevent light getting in. Also, please note the pots go on the side of the PCB that has the pot symbol screenprinted, this is different to previous NLC PCBs……I try to conform, its hard, really hard. Anyway look at the pics to make sure.
"This module turns any incoming signal into a series of 5 pulses. Each pulse can be inverted or positive and have its amplitude set. the Pulse width can be controlled by CV. A different kind of resonator.
Each has CV and pot controlled pulse width and the pulse for each can be set to be negative going or positive at any desired amplitude. The circuit is supposed to be driven by a signal from a VCO, but noise or chaos sorces are fun too. It creates five pulses that can be individually manipulated to create a complex and harmonically rich waveform. A slower clock signal will give clicks and glitches (so, a voltage controlled glitch module).
As the pulse widths can be individually controlled (or controlled en masse by “CV all”), this waveform can be continually morphed to get new sounds. When the 5 pulses are quite thin the effect is that of a resonator. The controls allow a wide pulse width, so fatter, thicker sounds can also be created.
"This is a re-boot of the bindubba3 sequencer, tho there have been a few changes.
It is designed to be used with the Divide & Conquer.
This sequencer has 6 inputs to control the stepping. Two clock inputs control the count in horizontal and vertical directions. The two jump inputs send the next step somewhere else that depends on the 2^2 and 2^3 counts of the chips of both step directions......ie somewhat uncontrollable but it enables more complex patterns to be created. The two direction inputs change the direction of the count.
There are two voltage controlled slewed outputs, two CV outputs giving the same CV, 1 inverted CV output and 16 gate outputs.
"SLY GROGAN is an envelope generator based on the design in Electronotes #86. It can produce a wide variety of different envelopes and bursts, perhaps most interesting is the ability to have the envelopes ringing after the attack stage. It also works well as a voltage controlled LFO, tho the module is neither a LFO nor a regular ADSR.
Please note: it no longer contains a VCA, this was dropped in favour of tapping the extra outputs (2&3)."
"Hyperchaos module - can be built to run at a variety of rates. The versions in this vid use 1uF capacitors and then from approx 2:25 slow right down with 10uF"
"1st play with the NULL-A. It has 2 VCOs, state variable VCF, ladder VCF, S&H, 2 LFOs, frequency divider, 3 VCAs, Sloth chaos, ADSR, 4 stage sequencer with direction control, mixer, VC Delay and a headphone amp"
"A short demo of the bong0. The one on the left has its raw signal patched to the mixer, the one on the right is patched to a Timbre! and then to the mixer. Both Bong0s are fed gates and CVs from a 4SEQ.
Bong0s can be set to self-oscillate and then be used as a VCO. Their sounds are quite rubbery and unusual.
Feeding triggers or gates to both inputs allows the creation of poly-rhythmical structures, where it sounds like 2-3 drum modules running at once.
"1st half of vid has 2x CEM3340 VCOs fed to a Timbre! and a FK1T VCF. In the 2nd half the VCOs are sync'd and just the raw outputs are fed to the mixer. The controlling patch from a dual LFO and 4SEQ is the same throughout."
"8bit Cipher being used as the timing & CV source for a patch involving Doofs, bong0s, badum Tisss, CEM33400 VCO, timbre! & LPG.
The 8bit Cipher is getting its clock and data signals from 2 LFOs.

"This is a proto-type of a CEM3340 based VCO. Just pleased it was working well so recorded a minute of it.
The production version will have a 2mm white panel with ENIG gold labelling."
The core sound of the circuit comes from the ring mod. Usually it will process the noise source and the VCO, but feel free to plug in the output from another VCO and get some nice sounds. You can use CV to modulate the VCO frequency (NOT 1/oct) and control the decay time."
"The squid Axon is fed a fast clock from a VCO and samples a tri-wave from an LFO, 2 CV outputs are to VCOs and 2 outputs to a 'scope in X-Y mode. It makes a nice lightshow."
