New free plugin: Damper resonance for sampled pianos (Win only for now)

[JeffLearman]

I just released the alpha version of a new open-source plugin that adds the resonance of the harp to sampled pianos. The plugin responds to the pedal up/down to mute or engage the resonance. It uses an IR file created by summing all the notes, and sounds remarkably realistic -- more so than other methods often used with sampled pianos (like pedal-down samples.)

The plugin is available at https://github.com/jlearman/PianoRes/releases/tag/0.1.0 . The zip contains a README on installation, and the repo's README explains usage. Usage is a little fiddly because software instruments usually don't pass on the MIDI.

The plugin comes with IR files for Accurate SalamanderGrand 6.2beta2, available at https://www.ir.isas.jaxa.jp/~cyamauch/A ... /#download . The default is a short (4 second) IR to avoid CPU usage, which didn't turn out to be an issue. There's also a 10 second IR that sounds better (but only if you hold the sustain pedal down that long!)

The controls are organized to make it easy to compare with/without effect using the bypass button, or to hear the effect alone by turning the dry level down. I find it's handy to use MIDI learn to map mod wheel to the "wet" control to see just how much effect is best, and to even more easily compare with/without effect.

Any feedback welcome! This is my first nontrivial plugin, so expect issues.

PS: old-timers may remember me as the author of the jRhodes sampleset.
