Yamaha Vintage Plugs

Does anyone else think that the Vintage Compressor 276 and the Vintage Open Deck are superb plugins?

Compressor 276 gives terrible distortions when attack is at minimum. Especially audible on electric piano, such as Neo Soul Keys. A bug, no less.
Exactly the same goes to AXR4’s Channel Strip’s Compressor. I doubt it should be like this. No other Steinberg compressor acts the same disastrous way.

Vintage Open Deck gives the kick fat bottom end when stacked at least 4 units.
