In the ever-evolving world of audio effects, few plugins manage to blur the lines between creativity, precision, and performance like REEV-R. Built on the highly efficient KlangFalter FFT convolution library, REEV-R takes convolution reverb into a new dimension by adding powerful modulation features—without crushing your CPU.
Where many reverbs choke under complex IR manipulation or modulation routing, REEV-R thrives. This free plugin is a testament to what’s possible when clever design meets modern audio development.
A Reverb Engine Reimagined
At its core, REEV-R is a convolution reverb. But unlike traditional plugins, it’s powered by KlangFalter FFT, avoiding the high CPU hit associated with JUCE’s stock convolution engine. In debug builds, the standard engine consumed up to 20% CPU—KlangFalter? Less than 1%. That efficiency opens the door to advanced real-time processing.
Beyond just loading impulse responses (IRs), REEV-R lets users manipulate them: stretching, reversing, trimming, and sculpting attack and decay curves. But IR loading is CPU-intensive—so REEV-R uses a smart system with two reverb instances: one active, one idle. The modified IR is loaded in the background, warmed up with a second of buffered audio, and crossfaded for a seamless transition.
Modulation That Rivals the Best
Let’s be clear: REEV-R’s modulation features are reminiscent of ShaperBox, and the developer acknowledges this—without denying that many of those features were simply too good to ignore. While ShaperBox Reverb remains a polished, studio-grade product, REEV-R offers a strikingly complete and free alternative.
From MIDI-triggered patterns to audio-based envelope restarts, REEV-R boasts flexibility:
- Paint Mode 2.0 lets you draw modulation with custom patterns, rescale them, and insert them into the sequence window.
- With 32 editable patterns, user-defined rhythm is only a click away.
- Point types (s-curve, curve, stairs, hold…) bring GrossBeat-style expressiveness.
- Multi-point selections allow fast manipulation—perfect for creating build-ups, glitches, or risers in seconds.
- Self-repeating patterns rotate seamlessly, offering endless rhythmic variation.
Trigger, Modulate, Sculpt
Whether using audio transients, MIDI notes, or a built-in sequencer, REEV-R is all about dynamic reverb control:
- Audio Trigger mode uses envelope following or energy detection to re-trigger modulation, great for drums and vocals.
- MIDI Trigger works on channel 10 by default, letting you map different patterns or restart the envelope in sync with your DAW.
- The sequencer and randomizer bring an experimental edge for real-time sound design.
Visual and Functional Feedback
REEV-R includes pre and post waveform displays, giving clear insight into how the reverb and modulation are affecting your audio. Combine this with tempo-sync, smooth attack/release envelopes, and MSEG modulation before and after the reverb chain, and you’ve got a tool that blends musicality and control.
