"It's hard to really judge audio critically because of all the background noise from nearby booths at NAMM."

No worries and completely understandable.

"But the analog modeling and modulation control sounded very natural. Alesis have done a great job on it."

Yeah have an Ion so was hopeful the VA was gonna be nice on the Fusion.

" Also the FM and physical modeling sounded very convincing as well. I have always been a big fan of FM so that is a big plus for me. And all the synth engines can be combined so some serious patches can be created on this machine."

Hahahah Fusion.
