I just had my first really long play on the Steinway yesterday, and was amazed by the 'realness' of the sympathetic resonance.
I'd like to write some pieces using the technique of depressing chords silently, and then using their resonances to reinforce what the other hand plays. The problem is I know absolutely nothing about velocity curves and the like. No matter how slowly I squeeze down a key I can't get it to play a note silently, or even close (I haven't checked what velocity value it's outputting, but it's miles off being quiet enough to ignore). I dare say I could alter the velocity curve to achieve a near silence, but it would have to be quite an extreme curve, and probably ruin the feel of the instrument for other purposes.
Is there any way to have a 'velocity offset' so that, say, the first 20 velocity values don't trigger a sound, but ARIA is still aware of those notes being held down?
