Fluctor Audio PhaseLock 2.5 | Realtime Kick & Bass Phase Alignment

One-line summary
Realtime kick and bass phase alignment for Ableton Live, with kick-triggered and low band volume shaping.

Description
Your kick and bass can be perfectly in tune and still cancel each other. The low end goes thin, the mix falls apart on club systems, and turning the bass up makes it worse, because the problem is timing and polarity, not level.

PhaseLock measures that relationship, shows you what is happening, and fixes it. Put it on your bass track, point it at your kick, and let it align every kick for you.

NEW IN 2.5

Realtime Auto-Align: PhaseLock measures every kick, and the bass that follows it, before you hear them. It then sets Rotation, Polarity and Delay for that kick just before it plays, so the alignment follows your bassline when the notes change. No clicks.

Low band ducking: the volume shaper can duck only the bass below a frequency you choose, 40 to 300 Hz, so the kick gets room in the sub while the body of the bass keeps playing. It has no crossover phase shift, and your signal is unchanged when it is not ducking. S solos the ducked band.

Rebuilt Align Score and a new Kick + Bass Sum panel that marks the clash areas in red.

Click-free Rotation, Polarity, Delay and shaper edits, and a scope locked to the kick.
