Erica Synths x Hexinverter Mutant BD9 sound demo

video upload by Erica Synths

"Hexinverter’s BD9 is a modular take on the classic TR-909 kick, enhanced with voltage-controlled distortion and added flexibility. Its analog VCO delivers sine or square wave bassdrums, with pitch ranging from 30Hz to 240Hz and full CV control.

Timeline:
00:02 - Take 1 / Going through the controls of the Mutant BD9
01:31 - Take 2 / Jam with Perkons Voice
03:06 - Take 3 / Exploring the square ewave core with SUB
04:51 - Take 4 / Jam with Sample Drum
06:06 - Take 5 / Fully open Decay with SUB on, sent through the Black LPG, which is being triggered with extra triggers separate from the main bass drum trigger"

Minimal Ambient w/ KORG NTS-1, OP-1 field, Tape Loop | Isle in the sky 2025-04-11 by atnr

video upload by atnr

"A piece created with the ‪@KORG_INC‬ NTS‑1, ‪@teenageengineering‬ OP‑1 field, and tape loops—a minimal ambient work where repeating arpeggios blend with tape‑sourced piano and melodic fragments.

KORG NTS‑1: Controlled via MIDI from the DAW. Its audio output runs through ‪@strymon‬ NIGHTSKY for reverb, filtering, and pitch modulation.

Tape loop: Routed through ‪@ChaseBlissAudio‬ LOSSY, which applies filtering and packet‑loss effects while fading the sound in and out.

OP‑1 field: Also driven by MIDI from the DAW. Bit reduction is applied with the built‑in TERMINAL effect, and the signal is further shaped with reverb and micro‑loops via the MOOD MK II.

Strings and additional layers: Overdubbed in the DAW."
