BO-1
BASS OCTAVER
Press LEARN once, and BO-1 tunes itself to your bass.
v1.0.1
Bass-First Design
Dual -1 oct / -2 oct subs that track your bass down to about 25 Hz
One-Button LEARN
8 seconds of playing sets SENS / GATE automatically, and the knobs glide to target
Product Description
BO-1 is a dedicated bass octaver that generates -1 oct and -2 oct subs from your bass.
Adaptive pitch detection and period-synchronous resynthesis reduce the glitches and octave errors common to analog octavers, tracking your playing cleanly.
It has 9 knobs and a LEARN button, and delivers consistent octave-down sounds in the studio or on stage.
Features
01
One-Button Setup
Press LEARN and play bass for 8 seconds. BO-1 analyzes the noise floor and harmonic character, then smoothly sets SENS and GATE automatically.
02
Dual Octave Down
Independently control level and tone for SUB 1 (-1 oct) and SUB 2 (-2 oct). Design anything from a simple octaver to a deep synth-bass texture.
03
Shape Your Tone
Sculpt the character with 4 knobs: TONE / GROWL / TONE 2 / BODY. From clean subs to gritty synth-bass, pick the voicing you want.
