## `invert split index`
> A utility plugin that inverts the signal, also (wrongly) known as a 180 degree phase shift.
## `tapedelay split index`
**TODO:** gives 0 output
> Correctly models the tape motion and some of the smear effect, there is no simulation fo the head saturation yet, as I don't have a good model of it. When I get one I will add it.
> The way the tape accelerates and decelerates gives a nicer delay effect for many purposes.
