I wanted to post an example of this piano expansion technique, and I'm sure I have many to choose from, but the trouble is that without the actual settings of the C4 in the mix for me to look at, going through the archives is futile. I think most of those settings are long since erased by upgrades to Waves, DP, and the Mac OS. (most of the big piano/ensemble recordings I did were in OS 7, 8, and 9, DP 2.73, and who knows what version of Waves) So, it's hard for me to say for sure which of my recordings use the technique and which do not. However I do remember one that definitely uses it. It's the one I was mixing when I figured it out.
Chicago: Hard to Say I'm Sorry. Five Piano arrangement by Ariel and Shooshie with a tiny bit of help from David Foster, who loved the arrangement and wrote the original song.
This is a piano ensemble recording. There are 5 pianos. One is the solo piano; the rest are analogous to an orchestra. I wanted the solo to sparkle like Peter Cetera's vocals. Instead, I was mostly hearing attacks that hammered like little pin points. My friend Ariel, a Soviet Moldavian by birth, was also disappointed that we couldn't get that melodic flow from the solo piano, even though we knew it was there. (Just solo the track, and we'd hear that beautiful 7-foot Yamaha singing like we wanted)
So, I spent an evening playing with C4 techniques, looking for a way to slow down the decay after each attack. I think you'll agree that in this final version from the album the solo piano is singing very mellifluously. I went back and remixed most of the album with this new technique, but I can't remember for sure which songs I did or didn't remix.
