Real-Time Quantum Bass Synthesis

BUILT FOR BASS

The OG Intelligent Sub Generator

Sub Generator Pro is a Max4Live device that transforms any audio source into deep, intelligent sub-bass perfectly locked to your track's key and rhythm. Forget static sine wave generators—this is a living, breathing bass synthesis system with real-time pitch tracking, scale-aware quantization, and dual-oscillator architecture.

Watch "The Architect" materialize your audio into quantized reality at 60fps and monitors the pitch tracking, envelope following and harmonic richness of your bass.

BUILT FOR HEAVY BASS WORKFLOWS

PITCH TRACKING THAT ACTUALLY WORKS ON BASS MUSIC

Sub Generator Pro's custom pitch follower outperforms standard pitch detection by combining Ableton's Pitch Estimator DSP engine with advanced signal processing:

• Sub-10ms latency pitch estimation with confidence-based weighting
• Vibrato detection removes micro-fluctuations for rock-solid tracking
• Adaptive dead zones prevent jitter without sacrificing responsiveness
• Exponential confidence filtering emphasizes accurate readings, suppresses uncertainty

SCALE-AWARE QUANTIZATION

The quantizer doesn't just snap to the nearest note—it understands music theory:

• Tonal gravity modeling based on Krumhansl-Kessler profiles (roots and fifths pull harder than passing tones)
• Directional momentum favors upward/downward melodic motion for natural phrases
• Hysteresis prevents rapid switching between adjacent notes
• Maximum jump limiting rejects octave errors from pitch tracking glitches

Zero-latency processing means the quantized output responds instantly to pitch changes while remaining musically intelligent.

Precision Envelope Follower

The compander-based envelope tracker shapes your sub's dynamics to match the input source:

• Expand mode for exaggerated attack/release
• Compress mode for tight, controlled dynamics
• Minimal signal loss Smoothing prevents harsh transients without giving up dynamics

FROM STUDIO TO STAGE

Sub Generator Pro isn’t just for heavy bass music producers in the studio; it’s also a valuable tool for any artist performing on stage.  It employs time-domain signal processing optimized for sub-10ms latency.  While spectral analysis tools introduce 50-200ms of lag, making them "unsuitable for live environments" (their words, not ours), Sub Generator Pro provides instant response.

Thee Operating Modes

SET Mode: Manual note selection with octave transpose (-36 to +36 semitones) Perfect for: Static sub drones, manual bassline construction

FOLLOW Mode: Automatic pitch tracking with scale quantization via Ableton Live API Perfect for: Melodic content, vocals, instruments - locks to your session's key

MIDI Mode: Play the sub generator like an instrument via MIDI clip or controller Perfect for: Live performance, precise bassline programming
