PSP Nexcellence provides two different spring set processors and can use one or both of its processing engines simultaneously. The algorithm has improved on the original hardware by providing a handy set of parameters to let a user control inherent aspects of the spring reverb.
To see PSP Nexcellence in action you can try it on your own material using the fully featured 30 day demo version available on their download page or watch the short promo movie on their YouTube channel
