## What is Rotary Mod?

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.

Features:
- 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 and Standalone app.

- Independent rotor and horn speed control
- Frequency modulation with secondary LFO
- Selectable cabinet size (Standard/Giant)

### 4/5 — I Must Be Expecting A Rotary Simulacrum

*2021-03-28, version 1.0.9*

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?

### 4/5 — AUv3 not working...

*2020-07-09, version 1.0.6*

1/ I bought this app to use it as AUv3 inAUM because they describe their app as functioning in AUv3 mode but in fact I can’t see it in AUM Adio Units extensions... even in Audiobus3... is it a bug??? 

 2/ Correction : par avoir éteint et réinstaller l’App tout fonctionne très bien. 

3/ very good sounding but as for even tide spring reverb, when you switch off the app in AUM you can hear 2 electronic clicking in your sound that can be loud in some case... For the reverb is not a big problem because I turn off rarely but for the rotary it is because every times your turn off your effect you have this artefact...

### 5/5 — Surprise

*2020-05-03, version 1.0.3*

Très bon son! Super d’avoir la quaité Eventide sur nos appareils!

### 5/5 — Rotary

*2020-03-28, version 1.0.3*

My only criticism is that when 
Rotary is in standalone or IAA form
midi is set to omni and the auv3
doesn’t accept midi in or out.

Other than that it’s a lovely
sounding effect which I’ve already used on both organ and Rhodes sounds.

Thank you
