You don't actually want an infinite reverb, it eventually gets too mushed up. Here is one set close enough for most purposes, and if you want infinite hold on a voice hit Ctl 1. Adjust the blend to your purposes, I have it set for an exp pedal.
It's a verb kind of night, I wanted to show that the SY can hang in there with the Ocean Machine, BigSky and pretty much everything else of that genre.
With the ability to pass the the guitar input to the filters and add V oscs, and then stack fx, the sy is in a class of it's own.
