Endless Vsti Instrument Loop

The guy with problems here :)

Maybe I’ve done to many changes to config. but I found that all VST instruments and some samples (but this may depend on loop setting in sample editor and instr. env.) have endless sustain-like effect. I can’t figure out what’s wrong with my configuration. It’s not about Sound driver version (Asio/Direct X) but may depend on driver version, dunno yet, and this happen with every VSTi.

Sondcard: Delta 24/96 with driver v 5.10.00.0027

Anyone with the same problem or idea how to disable this bonus feature? :)
