Fleer
Waiting for Godot (aka Play Pro).
No kidding. I remember when they called it "Play 2" which, as one might expect, means that Play 1 was current then. Then I remember them actually putting it on sale for a time for preorder... that was about, I dunno 6 years ago at least. Since then? Nothing.
I just got tired of it. With Play I always felt like I was walking on eggshells and had to bounce individual tracks as soon as they were ready, then immediately check for glitches. With Kontakt I just do whatever I want, don't bounch anything, and render the final project when ready.
