# Making a vibrato/chorus patch

{% embed url="<https://www.youtube.com/watch?v=2j6Uy3hlrC4>" %}

In this video, I show you:&#x20;

* a vibrato
* a single voice chorus (mono)
* expanding the single voice chorus to stereo
* using a Scale/Offset block to reduce the number of pots used for the chorus
* how to fine tune the patch parameters to suit your tastes
* a 4-voice chorus (no dry) in stereo
* double checking the 4-voice chorus in mono

Here's a link to download the [SpinCAD patch file](https://github.com/HolyCityAudio/SpinCAD-Designer/raw/master/patches/4-voice-chorus-again.spcd).
