Hi Paul,
I totally agree with the people expressing dismay regarding the sympathetic feature. It only does a little bit up to about six and then it turns to mud. Nothing like the sound of actually having the pedal depressed when a note is played.
I have a very simple solution that should use no CPU and would make me at least extremely happy. The sound with the pedal down is definitely superior. Put in an option to use the pedal down samples instead of the pedal up samples (when the pedal is up). I actually did this with the 10-year-old Imperial by means of sample robot and then the Kontakt 4 sampler. Unfortunately the process degraded the sound.
I hope VSL will take this suggestion very seriously because it would truly make these superior pianos (I have both the Bösendorfer Imperial and the Steinway).
Best, Phil
