Today I have something very special to show. In this video you can see and hear synth made from Syntaxis Micromodular set. Instrument is assembled from basic set of micromodules (uVCO, uVCF, uVCA, uLFO and uADSR), but it sounds quite versatile. User is able to assemble synthesizer on it's own, in modular way, but much cheaper and without necessity of use dedicated multipliers - breadboard does it already! Usually building subassemblies of synths on breadboard makes circuit unreliable in longer term. But with Micromodules it works like it was soldered together - you can assemble you own synth, get plywood, drill holes for potentiometers, screw them in place and carry your own synth around for gigs."

"This is a set of components for building a basic but complete analog synthesizer on a breadboard. Although it might not have professional look, you will be surprised with its professional sound.

The set includes:

μPSU·112·A
μVCO·3340·A
μVCF·3320·LP4·A
μVCA·3360·LIN·A
μADSR·3310·A
μLFO·3340·A

(breadboards, wires, potentiometers, switches, laptop charger are not included)

An example synthesizer circuit is shown in photos 2 and 3. Potentiometers and switches from left to right, from top to bottom:
- oscillator frequency coarse tuning (pot)
- oscillator frequency fine tuning (pot)
- wave shape selection: triangle, saw, pulse (switch)
- PWM control (pot)
- oscillator signal amplitude control (pot)
- cut-off control (pot)

All typical connections, including those used in the setup above, are described in micromodule's datasheets.

μVCA

μVCA·3360·LIN·A is a voltage controlled amplifier micromodule based on AS3360 integrated circuit,
configured for linear response. It is designed for final amplification stage in a signal path, prior
directly to the sound output in a basic synthesizer setup. However, DC coupled inputs allow
to use the module also as an attenuator or mixer for slow modulation signals. Up to 4 signal sources
(either audio or CV) may be connected to the unit. The amplifier’s gain may be controlled by
up to 4 CV sources.
