nABC: creative programmable sidechain compressor
The nABC idea: transforming sidechain compression into a creative tool
The nABC is capable of “classic” stereo compression, thanks to its transparent VCA-based analog circuit. But what makes it unique is the flexibility to combine analog and digital sidechain triggers, enabling new creative possibilities. Attack and release times can be controlled with millisecond precision, compression depth is adjusted to fractions of dB and all parameters can be MIDI-controlled in real time.
The nABC is capable of classic off-beat ducking/pumping, as commonly used in electronic music, as well as more creative dynamic sidechain patterns, not necessarily in sync with the kick drum. Use it on a bus, on a synth, on a pre-amplified bass, guitar or voice or on any instruments/tracks.
Supported sidechain triggers: USB/MIDI, Gate/CV, Line Audio, External (S/C) Audio, Pedal.
Design sidechain patterns in your DAW and use USB/MIDI for millisecond-level-adjustable attack/release envelope control.
The nABC is easily connected to any sequencer/modular synth with its MIDI, gate and CV sidechain controls. You may connect it to a sequencer for new compression patterns and use the CV to dynamically adjust the sidechain compression depth .
Sidechain compression is relatively uncommon in small live setups, mostly because of the required cable routing and lack of battery-powered portable compressors. The nABC solves these problems and gives new creative opportunities for live musicians.
