The more I work with Pianissimo, it isn't suiting my needs so still considering GAS Basic. I won't be using it to record, only as a practice tool so I can hopefully hear a more natural acoustic piano sound than the grand piano samples in my keyboard, although they're pretty good. For practice, I either use good headphones or my Altec Lansing speaker system via computer.
Since you've been using GAS Basic, how does it sound through headphones? Good balance with good highs and lows? Good character? The problem with Pianissimo is it's too warm for my taste and bass notes in particular can sound muddy and indistinct. Playing a piece like Liszt's "Un Sospiro" with the constant flowing bass runs which is the basis of the piece, sounds rather muddy in Pianissimo even with the high EQ set to max. So just curious to get your opinion regarding overall sound and playability of GAS Basic from bottom to top.
I'm also trying TruePiano and overall sounds very good except for a few notes in the low end that sound more like an upright than a 9' grand. Disappointing for the price. You'd mentioned IvoryII before but it's just more than I want to spend for my needs and I want to use a stand alone.
