GyroVibe is an Audio Unit, or AU, for iOS. This application is simply a container for the Audio Unit and also serves as the documentation for the AU. GyroVibe must be used in some sort of Audio Unit host or DAW application.

GyroVibe evokes the sound and textures of a classic vibrato chorus. It also contains multi-stage driven filters that will swirl and swoosh your instrument all over the stereo field. GyroVibe is perfect for adding depth and color to keyboards. It's equally adept at adding some psychedelic soul to guitars and bass. GyroVibe can be used in mono-to-mono, mono-to-stereo, or stereo-to-stereo settings. Several of the features work best with a stereo output.

GyroVibe has three sections – a Filter with LFO, a Vibrato/Chorus section, and the Mix section. The Filter section is based on our multi-stage driven filter. It is an active filter with up to four sections. Each section of the filter can be heavily driven. This can result in a large degree of distortion. But, the distortion is very smooth. The LFO has several different waveforms. The vibrato/chorus section is a multi-voice, vibrato chorus that can generate modulation effects from vibrato to chorus and flanger and phaser-like. The mix section provides basic control for wet/dry effect levels and the final output volume for GyroVibe.

Free & Functional

Chorus/vibe effect w/ all parameters adjustable for creating presets. More parameters than I need to get unique sounds but happy to have the options.
Sound quality is 3.5-4 out of 5 (it may be I don’t know how to adjust it to get the best sound), fully adjustable & free = 5 out of 5.
I use this often for rotating speaker effect & tone modulation. There is a wide spectrum of attainable sounds possible. It is free but I would be happy even if I had paid for it.
Thank you for this!

Very stable too, haven’t had a crash from it & use it a bunch. Neon Silicon effects are psychedelia personified. I only wish it had some kind of tempo sync, but the interface is so clean it’s pretty easy to dial those rates in manually.
