In this case, as advised by Modartt, the black notes in the MIDI file no longer are voiced; instead, they shift the key signature of the white notes.

I love this one enough to make it the default video on my YouTube channel.

MIDI didn't exist when I was a tween but I have long forgotten what I called it then, if anything. I now call it Untitled Concerto for MIDI.

Now that I have Pianoteq, I have created four new versions, all with the same MIDI data and using only Pianoteq voices. Here they are for, hopefully, your listening pleasure:

Untitled Concerto for MIDI NY Steinway D Classical 0.3 Worn
Uses:
NY Steinway D Classical preset
Wear set to approximately 0.3

This would be the closest to my original Logic Pro release, with the added richness of the Pianoteq technology. It might be interesting to compare the two for the differences.

Untitled Concerto for MIDI NY Steinway D Classical in Bohlen-Pierce Tuning
Uses:
NY Steinway D Classical preset
Tuning set to Bohlen-Pierce

Interesting to hear how Bohlen-Pierce reduces the dissonance in the piece. That's reduce, not eliminate. Makes me want to hook up a keyboard and mess around with this tuning and learn more about it.

Untitled Concerto for MIDI with Celtic Harp Sweet in Diatonic
Uses:
Celtic Harp Sweet preset
Diatonic setting
https://www.youtube.com/watch?v=t_6ABOc-xr4
In this case, as advised by Modartt, the black notes in the MIDI file no longer are voiced; instead, they shift the key signature of the white notes.

and finally:

Untitled Concerto for MIDI with Cimbalom Voice
Uses:
Cimbalom 392 preset
https://www.youtube.com/watch?v=aGUPKJMPYpI

I particularly love the last two; the voices apply a beauty to the dissonance of the piece.
