Blend two oscillators with sub and noise to build everything from a clean fundamental to a dense harmonic core
ONYX combines two flexible oscillators, analog-minded variation, nonlinear filters, deep modulation, sequencing, and a complete effects rack in an instrument that stays immediate under the hands.
A 1950s space-age vision of warm synthesis, expressive motion, and finished sound
Blend two oscillators with sub and noise to build everything from a clean fundamental to a dense harmonic core
Use PWM, drift, unison, hard sync, cross modulation, and ring modulation to keep a held note alive
Move from stable clarity to worn, animated weight with Condition, drive, and two nonlinear filter models
Shape how every note speaks through velocity, three envelopes, performance macros, and flexible voice modes
Turn chords and single notes into timed phrases with a 16-step arpeggiator, swing, latch, ties, and holds
Finish the patch with drive, chorus, phaser, delay, reverb, tone, compression, and limiting inside the instrument
A readable left-to-right architecture keeps sound generation, filtering, movement, performance, and finishing connected, while advanced routing remains available when the patch needs to go deeper.
ONYX keeps the primary voice path direct while giving modulation, sequencing, performance, and finishing enough range to turn a simple waveform into a complete playable patch.
Combine waveform blends, pulse width, tuning, sub, noise, sync, cross modulation, ring modulation, and unison before the signal reaches the filter
Create repeatable motion with two LFOs and three envelopes, or introduce controlled individuality through drift, voice-card variation, and the Condition macro
Choose poly, mono, legato, chord, or unison behavior, map eight performance macros, and audition across the persistent 88-key keyboard
The tested oscillator path uses band-limited wavetable generation and four-times oversampling for dynamic wave shaping, with smoothed click-safe transitions and allocation-free rendering after preparation
