Here’s what TipTop Audio say:
ZVERB is a collection of all new reverb algorithms developed by Tiptop ranging from typical reverbs to more complex effects that combine delay and pitch shifting with reverb.
The effects are grouped by decades based on either the era an algorithm was introduced or the time when the effect was most popular. This variety of reverbs covers small to epic size spaces with the addition of shimmering, feedback tunneled pitch shifting, tape delay drivers, gated reverbs and a lot more.
Analog clocking of the DSP chip and CV over the parameters enables even more experimentation. This is a collection inspired by the best from the past right at your fingertips.
