Until now, the piano sound source has been "Synthogy Ivory II Italian Piano" or the same
I used "Amreican Concert D."
The Vienna Symphonic Library recently announced a new piano sound source. "Vienna Synchron Concert D-274". I listened to the demo and found it to be quite good sounding. I had been paying attention to the Yamaha CFX, but I decided to take the plunge and get the D-274. I compared it with Ivory in various ways, but decided to switch to this one because of its ease of use for me, sound quality, etc.
I will need to rework some of the songs I have typed before switching from Ivory to VSC D-274, but I will continue to make corrections as I go along.
