Orra Pump
Key Features
- Drawable curve editor lets you place, move, and bend control points instead of relying on fixed LFO shapes
- Six modulation targets cover low-pass, high-pass, band-pass, notch, volume, and pan movement from the same curve
- Loop, one-shot, and triggered loop modes make the modulation work as a synced groove tool or a sidechain-reactive effect
- Stereo, mid, and side routing can process the full signal, only the center, or only the width for more controlled motion
- Swing grid and snap-to-grid drawing help rhythmic filter and volume shapes sit naturally against shuffled beats
- Live visual overlays show playheads, smoothing, output ghosting, and trigger activity while the effect is running
- Zero-latency processing makes it practical for real-time monitoring and tracking workflows
Description
Orra Pump is a tempo-synced modulation filter for macOS and Windows that turns a drawn curve into rhythmic movement. The curve can drive resonant filter sweeps, tremolo-style volume motion, or auto-pan movement, with looped, one-shot, and sidechain-triggered modes for matching the effect to the groove.
The interface is built around direct curve editing instead of preset LFO shapes. You can place and bend control points, snap them to a swung grid, then aim the result at low-pass, high-pass, band-pass, notch, volume, or pan targets.
Its routing makes it more flexible than a basic pump effect. Stereo, mid, and side modes let you move only the center or width of a sound, while the stereo control can split the left and right playheads for wider motion from one shape.
Because the download runs through Orra's secure free/pay-what-you-can checkout, it is best treated as an external product-page download rather than a hostable direct installer. The launch coverage also confirms the permanent pay-what-you-can positioning and highlights it as another useful Orra freebie rather than a short promo.

Frequently Asked Questions
What can Orra Pump modulate?
The drawn curve can target four filter modes, volume, or pan. That makes it useful for pumping ducking-style movement, rhythmic filter sweeps, tremolo gates, and tempo-locked stereo motion from the same interface.
Can Orra Pump react to a sidechain?
Yes. Orra lists loop, one-shot, and loop-triggered modes, and the trigger source can come from the track itself or the host sidechain bus. That lets the curve restart from incoming hits instead of only following the DAW timeline.
Does Orra Pump work for mid-side movement?
Yes. The channel selector can aim the processing at stereo, mid, or side content, so you can filter the center while leaving the sides alone or add movement only to the width of a sound.
Does Orra Pump add latency?
No. Orra states that Pump is zero latency, which makes it suitable for monitoring through the effect while recording or playing live parts.
