AudCalc, Zeptocore, Phantasmal Force, GREAT CONJUNCTION Micro Synth Coordination


video upload by Arman Bohn

"Let's get these little NOT-calculator devices together and see what happens!

The Phantasmal Force is just providing MIDI clock - which I'm feeding into the Zeptocore, GREAT CONJUNCTION and AudCalc to keep them all in sync.

The Zeptocore provides the chopped up drum breaks/loops. It can be found here: https://zeptocore.com/

GREAT CONJUNCTION adds melodic and percussive chaos.

AudCalc is providing the underlying sequence (simple kick/snare, bass, and some melodic percussion and plucked string sounds).

I'll be posting just the AudCalc track later - for those curious about what it can do.

Audcalc is a pocket synthesizer and sequencer. It has 8 voices which can switch between synthesis (using mutable instruments braids cores) and sampling. The sequencer supports parameter locks, conditional triggers, and various time signatures and loop lengths. There are also two built in effects sends for building a full track. Its fun to jam with by itself, and can link into your larger portable music setup via midi or cv clock. Features: - 8 simultaneous synth or sampler voices, 16 midi outs - 16 sequencer channels - 16 patterns, supports pattern chaining for songs - channels can send to synthesizer, sampler or midi out - each voice has 2 assignable envelopes, LFO & filter - reverb & delay sends - sequencer supports midi clock sync or CV sync, both in and out - assembled by me & open source (open firmware, hardware, and enclosure)

Novation Bass Station II Swifty


video upload by MKustomAudio

"The Bass Station II was the first Novation synth I purchased and, with my original unit wearing out, I decided to swap it with the new limited Swifty edition. Except for the end bass guitar and vocal elements, all sounds are from the Bass Station II with additional processing added in post. For the bass guitar and vocals, these were processed through the external in on the synth with the oscillators also being played alongside the vocal element."

I beleive this might be the first still / pic of the original box on the site.
