Seismic

A clean sub-bass synth that key-tracks an input signal — or stands alone as a sub MIDI synth. Optional harmonic enhancement gives you the low end that still translates on a phone speaker.

What it does

The low end
that translates.

Seismic lives in the bottom octave. Play it as a MIDI sub synth, or feed it audio and let it key-track to add a sub layer under anything tonal. A separate harmonic fader buys you perceived bass on small speakers without touching the real sub content.

Pure sine sub

Clean sine-based sub with optional 2nd-harmonic blend — controlled at the source, not corrected after.

Key-tracking

Feed an input signal and Seismic tracks its pitch — layer a sub under a vocal, a synth, or a bassline.

Harmonic enhancement

An independent harmonic-only output for small-speaker translation that never changes the sub bus.
