Embarrassed to admit I bought it, but Sampletank 3 and the lower end Miro 2. I had picked up a ton of ST2 / Miro 1 stuff dirt cheap years ago and had fun with it. Thought ST3 / M2 would be on par with say mid tier modern stuff. Boy was I wrong. Terrible sound, terrible interface.
Heavyocity Intimate Textures
The textures are a cool idea, but these recordings are scratchy in a harsh and unpleasing way for my ears. Many of them are also on the busy side for me. The other stuff, the whole processing strings through distortion, compression, gating and sequencing just sounds awful to to me. It just sounds so gimmicky. While I can get some use out of the basic texture patches (so long as I EQ them), I do regret the purchase
8Dio Agitato Legato Arpeggio (What good are the ostinato phrases if they don't loop. Useless library and waste of money)
8Dio Aura Guitars (Poor interface and usability)
Spitfire Phobos (I don't really resonate with it so far and doubt I'll use it much)
Sample Logic Rhythmology
too many others not worth mentioning
