This sofsynth dethroned the B4 as my alltime favorite softsynth so far. Infinitely playable, and *very* easy on the CPU. The Tremolo is on the money and really helps the e-piano show some character in the Mix. My one complaint? Emagic currently has no plans to update it with the other e-pianos in it's proprietary big brother (the EVP88) which only works in Logic Audio.
I use the EVP73 in SONAR through FXPansion's VST Adapter.
