Space Brain Circuits has released a small batch of its first publicly available instrument, the DarkSky-4 stereophonic analog polysynth, selling on Etsy and looking really interesting, as well as picking up some decent user reviews. Currently it is limited edition simply because it’s handmade in small batches and is currently (at time of writing) sold out.
DarkSky-4 is a four-voice stereophonic analog synth, consisting of four independent oscillators that can be played monophonically, paraphonically or polyphonically.
Each oscillator is equipped with a dedicated VCA and Envelope, which allows for better musicality and the ability to sound each note as it is pressed. Each oscillator contains a sawtooth and square wave, which can be mixed to generate various timbres and sounds.
The square waveform can be gradually adjusted from a square waveform to a narrow pulse width waveform to further expand the sonic characteristics of the oscillators.
The synthesizer also features two 24dB low pass filters with dedicated controls for cutoff frequency and resonance peak.
DarkSky-4 provides several ways to add modulation to the audio signal, including frequency modulation, pulse width modulation, and filter modulation.
The unit was designed to create a more expansive soundscape for studio and performance settings. The filter adjustments, along with filter modulation, provide a wide range of stereo effects when in stereo mode. Additionally, the semi-modular patch bay can be used to further modulate multiple sources of controls.
Connections include 1/4 inch TRS jacks for audio output, a standard MIDI in port, 1/8 inch TRS MIDI out port, audio in, fine tune knob, USB mini port for firmware upgrades, and DC 12V power jack.
DarkSky-4 has been in development for over two years by Austin Luberda. Check out the video below for an introduction to the synth.
