Fran, not sure I know which was the 'sticky' E. Piano.

The A11 main piano is no longer in the G70, but, IMO, the GrandX works in a similar sonic space, but with MUCH greater dynamic timbral range. In fact, IMO, the rest of the pianos in the G70 are a total waste of space. GrandX is SO good, the only other one I use for anything is the Honkey-Tonks...

BTW, if the GrandX is a little dark at times (for rock or pop tunes), try reducing the Resonance by 5, and increasing the Filter Cutoff by 5 in the Tone Edit. It beats (IMO) EQ-ing it brighter, or the MFX Enhancer...
