Puremagnetik has just released Bluejay - a VST plugin designed to give you supersaw synth action. Its inspired by the Roland JP8000 and includes supersaw and super-square algorithm. The shape of the saw and square wave is also morphable via a dedicated macro.
Bluejay is part of Puremagnetik's Spark subscription for $8 per month. After one month it will become back-cataloged for a la carte purchase at $20 USD.
