via this eBay listing

"This listing is for a vintage 1980's Ensoniq ESQ-1 Analog/Digital Polyphonic Synthesizer Workstation that comes with an Ensoniq Sequencer Expander Cartridge and power cord. This synthesizer is in good physical and working condition. The winning bidder will receive exactly what is pictured.

The Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but is actually an early music workstation. Although its voice generation is typically subtrative in much the same fashion as most analog synthesizer that preceded it, its oscillators are neither voltage nor digitally controlled, but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.

Sunset Ambient on a DIY synth


video upload by KellerDev

"Generative sequence on DIY eurorack analog synthesizer. The sequence is quantized to major scale. It has 16 steps, each of which can have up to 8 subdivisions. The sequencer plays them with some random variations. 4 LFOs control filter cutoff, PWM of the oscillator and feedback of the reverb. The delay module that uses the Daisy Seed board is the only digital effect."

This little beauty packs up a lot of cool tricks in a rather small package with drive and audio control inputs on each channel. The audio control inputs is an envelope follower that will allow you to compress, gate, duck your VCA output from any audio sources.

Roland MC-303 | 160BPM DNB


video upload by Akihiko Matsumoto

"In modern production, the most interesting results often come not from layers of weight and power but from the spaces in between. The Roland MC-303, released in the late 1990s, carried this idea into the hands of producers worldwide. Its tones are not always fat or saturated. Instead, they are brittle, sometimes almost hollow. Yet when placed inside today’s dense arrangements, these sounds can cut through with surprising precision and rhythmic character.
