Using a sample provided by Kevin Hobby I used Dimension Pro to model a hyperpiano – a much more satisfying experience all around. (see attempt 1 which used pianoteq and other details) An obvious path forward is to implement filtering based on the keyboard slope. This would help the matching to the real instrument as heard in the video.
Melodyne finds this sample to be three notes, A result I am assuming due to the inharmonic nature of the sound.

The next step in the analysis is to look at the audio spectrum of the sample and the isolate partials Melodyne found. (The notes in Melodyne can be deleted separately.)
