About
BassForge listens to every note you play, tracks the pitch using YIN detection, and generates an octave-down bass voice that follows your playing — note by note. It's not a pitch divider. It's a pitch-aware instrument engine, tuned for the low end.
Signal Chain
INPUT COMP
A FET-style gain stage before pitch detection. Levels your playing so the pitch engine tracks cleanly whether you're picking lightly or digging in hard.
PITCH ENGINE
YIN pitch detection tracks your exact played note. Granular/PSOLA shifting moves it down an octave with the texture and feel of a real bass — not a frequency divider.
FUZZ
Phone and tablet speakers can't physically reproduce 40 Hz — but they can reproduce its harmonics. The fuzz adds overtones above the fundamental so the bass registers on any speaker, even when the fundamental itself is below what the driver can move.
VOICING EQ
HPF at 35 Hz cuts rumble. Body boost at 100 Hz. Mud notch at 300 Hz. High-shelf tame at 3 kHz. Four points dialed in for sub-bass output.
SPECTRUM
A 2048-point real-time spectrum view with a pitch indicator line so you can see exactly what BassForge is tracking and outputting, moment to moment.
HPF / LPF HANDLES
Drag the HPF and LPF triangle handles directly on the spectrum to sculpt the band BassForge listens to — without touching a separate controls panel.
IN / BYPASS
A slide switch in the header takes BassForge completely out of the signal path — useful for A/B comparisons or silencing the bass voice mid-session.
DRY THRU
Bass on the left channel. Dry guitar on the right. Loop them independently in LoopyPro without extra routing setup.
Activate DRY THRU and BassForge splits its stereo output: processed bass on the left channel, your original dry guitar on the right. In LoopyPro, route those channels to separate loop tracks and record bass and guitar in a single take — no second pass, no overdub.
