RatRiser

Overview

RatRiser is transitions without the sample pack. Drop it on a track, draw one automation ramp on the Rise knob, and it does two jobs at once: generates the riser itself — noise sweeps, Shepard-style infinite pitch rises, accelerating tempo-synced rolls, sub drops, impact hits — and works over your track audio with filter sweeps, reverb wash, shimmer, stutter, and ducking. Four preset categories cover the whole arc: Riser builds, Downlifter falls, Impact fires a one-shot hit, and Combo does the full build-hit-washout from a single ramp. Any preset can fire an impact at the top of the ramp, and you pick the hit — boom, crash wash, sub drop, thump, noise slam. Presets define the deep internals; a small set of macros scales and colors them, so there's no wall of knobs. At 0% rise it's bit-transparent — completely out of the way until the transition starts. Because the automation lane is the transition, every render is deterministic: no internal clock, no trigger guesswork.

Features

• One automatable Rise knob drives the entire transition
• Riser, Downlifter, Impact, and Combo preset categories, one click apart
• Impact at the top of any ramp, with seven selectable impact sounds
• Generates noise sweeps, Shepard risers, rolls, sub drops, and impacts
• Simultaneously sweeps your track: filter, wash, shimmer, stutter, ducking
• Tempo-synced roll acceleration from the host BPM
• Bit-transparent at rest — zero coloration until the ramp starts
• Preset-driven with macro controls, not a wall of knobs
