When playing an acoustic piano, releasing the keys usually makes a subtle, dull thud as the key springs back up to neutral position, especially if this is done very quickly.
I've been trying out several different piano synths, plugins and samplers, and as far as I can tell none of them attempt to replicate this sound. I suppose that this is because the effect is not considered desirable, or maybe on the more expensive pianos that are usually modelled/sampled this effect is not so pronounced as on the cheap upright pianos I am used to.
However, I find myself missing it, and since there is a midi keyup event, I wonder if maybe there is such a plugin out there that I have simply missed. Can anybody enlighten me, or tell me what I should be searching for?
