Spinn now works entirely standalone! Import your audio, tweak to taste, then export the result. You can of course still use it as an AUv3 plugin if you wish!

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.

Sorry thought I updated this

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
