New thing posted in the Electronics section: a very basic square and triangle wave generator. Schematic and some notes can be found here.

After way too much time away from electronics, I finally have something new to share. NANDulator is a simple but fun noisemaker based around two CMOS chips. Check out the demo video below, and have a look at the dedicated page for more info and a schematic.
NANDulator: a wonky, lo-fi DIY noise synth
NANDulator is a simple, lo-fi, CMOS-based noisemaker synth. It uses two IC’s, a CD4093 (quad NAND gate) and a CD4046 (VCO/phase-locked loop), and a handful of passive components. I think it’s simpl…
Just added: 3 sets of multisamples in SFZ and Decent Sampler formats from a Casio CZ-1000, including two bass sounds and a sort of electric-piano-like kind of sound. Download below, or see the Samples page.
Cymbols is a percussion synthesizer specifically designed for electronic cymbal and hihat sounds. The methods it uses to synthesize sounds are derived mostly from old analog drum machines (with a few tweaks), though it is not designed to specifically emulate any one machine or series of machines.

Some 13 years later, I’ve done a little revision to the Modutronic Messmaker circuit schematic. The Messmaker was intended to be a “beginner” build, and this new revision removes some complexity (and cost). The original version is also still available here and from a link on the page.
The original version includes a direct output from the 555, as well as inputs for the LM567 AM and the 555 CV in. My original thought was that these would be cool features for a beginner’s circuit, giving one easy access to some modular-style interconnectivity. However, all these years later, even I have rarely used these features. The quick & dirty nature of this circuit also means they don’t work the way one might expect with other modular stuff, which has become more common.
Another fairly simple noisebox synth combining an AM/FM oscillator configuration with an Atari Punk Console-style triggered monostable.
Video demo:
FSA Latcher demo – VST3i noisebox synth
Latcher is a VST3i noisebox synth in the same vein as NANDroid and XORbot, and contains many of the same features as those previous synths. The sound-generating part is something of a cross between a circuit I built called the Modutronic Messmaker (an AM/FM noisebox), XORbot, and an Atari Punk Console.
Latcher is a noisebox synth in the same vein as NANDroid and XORbot, and contains many of the same features as those previous synths. The sound-generating part is something of a cross between my Modutronic Messmaker circuit and an Atari Punk Console, in that it combines the AM/FM oscillator configuration with the osc-triggered monostable of the APC. In keeping with the logic-based theme of the previous two noiseboxes, it also includes a switchable “mod osc” that is fed into an XOR gate with the APC-like signal on the other input (pre monostable).
Here’s a little audio demo:
NANDroid and XORBot have both been updated to V1.01, with the biggest change being that MIDI note value is now available as a modulation source in any of the assignable slots, including the Combiners. This change is largely thanks to a user request.
Another change is that these and other FSA plugins will now be available from Gumroad. They are still available for free if you like, just enter a price of “$0”.
Just for fun, some ultra-minimal technoid made with Giorgio Sancristoforo’s early electronic music studio simulation, Berna3. The video was made with TouchDesigner.
