This is the source code for Lost N' Found Piano, a virtual instrument plug-in that combines updated versions of the classic mda Piano and mda EPiano VSTs and gives them a new coat of paint.
mdaPiano is a sampled acoustic piano, mdaEPiano is a Rhodes electric piano. Both were quite popular free virtual instruments back in the early 2000s. The reverb effect is from mda Ambience.
Lost N' Found Piano mostly exists for nostalgic reasons and because the old VSTs don't work very well on modern computers anymore. It may not be the best sounding piano in the world, but it's still fun to play!

- The window size is not remembered when you close the plug-in.
