[Techno-Double8] Unity

I was thinking of making a 16-panel chart for this song and making it impossible like the piano in this video, but it would be hard to do since there are not enough keys on the keyboard to add the last 6 notes:
1 - P1 DownLeft
2 - P1 Left
3 - P1 UpLeft
4 - P1 Down
5 - P1 Up
6 - P1 UpRight
7 - P1 Right
8 - P1 DownRight
9 - P2 DownLeft
0 - P2 Left

I don't know if these work:
- - P2 UpLeft
= - P2 Down

Techno-double8 is available in SM5 only. And to make all 16 panels visible a mod like 25% mini would have to be used...

Also here is proof 16 panel exists:
