## What is Spinn?

Spinn is a 4 band rotating modulation effect. It’s a bit similar to a Leslie but not aiming to replicate this character. 4 rotors with individual speed controls, acceleration and deceleration times, adjustable size and modulation. Each band also has a velocity control, which will adjust the speed according to the bands input level. Spinn features custom amp modelling (clean or hot) and room simulation.

Global features:
* Speed mode - (Slow, Fast, Off).
* Room - (Small, Medium, Big) with mix control.
* Amp - Clean or hot with 3 band equaliser and a drive control.
* Stereo width control.
* Crossover points
* Input and output controls.

And for each band:
* Size - The rotor size
* Mod - Modulation amount
* Slow and fast speed control
* Acceleration and deceleration times
* Velocity - makes the speed change with input level
* Level - Band level

Spinn works both as a standalone app and as an AUv3 plugin.

### 5/5 — Learning curve

*2020-11-02*

It took me a while to learn this app...which is fine...but  once grasped it is a super .. subtle  ...or not so subtle effect....it’s a keeper 👏👏👏🙏🎶🎩🦄 Limbic Parsnip Lesion

### 3/5 — Sorry thought I updated this

*2020-05-23*

It is compatible as my second edit of my previous review didn’t post. Only the star rating made it? The only issue I have is that I thought it was a stand alone. The fault here was user issue.

**Developer response:** Spinn works fine in Garageband as a AUv3 effect plugin. Here's a link to a video tutorial how to add AUv3 effects on a track in GB: https://www.youtube.com/watch?v=K2o-THwOnFY
