https://drive.google.com/file/d/1hAeJr1...sp=sharing - brighter mez hammer

Using PT 8.30 (a historical subversion) I made 2 presets for limited range MIDI sources. After discovering supra.stanford.edu via
"Paderewski in your living room - pianoteq 8 - welte mignon" by williwow I thought I would share a couple of results. The brighter mezzo hammer is closest to the presets I've been working with the past week. On an impulse, I also thought to try a softer mez hammer. Even though my impulse came as a secondary reaction (after overcompensating for the resonance changes in 8.31),  I liked the results enough to try it on my standing favorite custom preset branch.
