Kemper Profiler OS 12: New Tremolo, Slicer, and Auto-Pan Effects

Kemper’s Profiler OS 12, released in November 2024 as a free update, adds 7 new amplitude modulation effects to the platform: 3 vintage tremolo models (including Tube Bias and Harmonic Tremolo), 2 slicer effects (Pulse and Saw), and 2 stereo auto-panner effects (Pulse and Saw). These tempo-syncable effects include unique morphing capabilities that allow seamless transitions between note values without audio glitching.

Tempo Morphing

The standout feature of the OS 12 effects is tempo morphing, which allows players to smoothly transition between different note value subdivisions (eighth notes to triplets, for example) without any glitching or audio artifacts. Combined with TAP tempo sync and retriggering capability, these effects provide rhythmic precision that integrates seamlessly with live performance.

Who Should Buy the Kemper Profiler OS 12 Update

Every Kemper Profiler owner should install OS 12. The new tremolo, slicer, and auto-pan effects add creative modulation options that were previously missing from the platform. If you play styles that lean on rhythmic effects — from country tremolo to electronic-influenced slicing — this update fills a real gap. It’s free, it’s easy to install, and it adds genuinely useful tools to your Kemper without requiring any additional hardware.
