Rotary is a rotating cabinet effect that simulates a Leslie speaker. It produces a pulse-like vibrato effect depending on the speed of rotation. Rotary offers precise control to dial in the exact amount of movement you need. This classic, swirly effect has been used on countless hit records to drastically transform guitars, bass, synths and even vocals.

- Change the speed of the rotor and horn independently and adjust the mix of the two to produce pulsing effects and special vibratos
- Add frequency modulation to the rotor and horn speed using secondary LFO with selectable modulation source
- Choose cabinet size (Standard or Giant) to alter the sweetness of your tone
- Craft the exact sound you need with included Hicut control
- Use Tap Tempo to sync effect to the BPM of your song
- Incredibly easy to use with included presets
- Innovative Ribbon control allows for changing any combination of parameters simultaneously
- Use Mix Lock to scroll through presets while keeping the wet-dry mix constant
Available as an Audio Units AUv3 plug-in, Inter-App Audio, and Standalone app

I Must Be Expecting A Rotary Simulacrum

Not a Rotary Simulation ... which is not a fair expectation. Wanting or expecting something that is better than the original is a good goal to set, but depending on your audio set up, you probably won’t be blown away by drifting separated stereo sources. It does what it does very well, but if you are applying the effect in an iPad and listening to the onboard speakers or equivalent, expect it to be more like a ramping tremolo. I haven’t yet hooked up to better monitors to find that rotation that should be there, but even without my unfair ideal (thinking more like WAVES stereo Doppler effect where the farther the sound the slower the ramp, etc) it’s still a great effect.

Soooo ... when am I going to get a Doppler effect, Mr Eventide?
