The four sensors are working like a binary encoder. But sometimes the mechanical "bits" are not activated at the exact same time. Therefore some of the notes starts with the wrong frequency but after a few milliseconds it switches to the right one. "E" has the code 0101 but it will often start as 0001 - which is "C" - untill the key is fully depressed. That's a common problem with mechanical encoders: They are only right when the movement is completed. Halfway down the keys are unpredictable.
De fire bjælker nedenunder "tangenterne" bliver nedtrykket af et antal klodser under den enkelte tangent. Hver bjælke er forbundet til en lyssensor som registrerer om bjælken er trykket ned. Hvis bjælkerne nummereres 1-2-3-4 kan man udtrykke det således: - C = 1 - C# = 2 - D = 2+1 - D# = 3 - E = 3+1 - F = 3+2 - F# = 3+2+1 - G = 4 - G# = 4+1 - A = 4+2 - Bb = 4+2+1 - B = 4+3 - c = 4+3+1 - 4+3+2 og 4+3+2+1 bruges ikke
Så forstod jeg det rigtigt :D C= 1000 C#= 0100 D= 1100 D#= 0010 E= 1010 F= 0110 F#= 1110 G= 0001 G#= 1001 A= 0101 Bb= 1101 B= 0011 c= 1011 0111 og 1111 bruger du ikke. Hvilket betyder at du kan lave to tangenter mere eller?
Jeg overvejede at lave de to ekstra tangenter der var muligt. Det kneb bare med pladsen, og desuden virkede en hel oktav som et rart afsluttet tal - måske fordi jeg er vant til at se på en afsluttet oktav i orglets pedaler.
That's awesome. I love it.

with 12 NXTs you can also make a polyphonic keyboard of one octave for example

is it the way the light sensors are doubled up per key that give it the "hammond percussion" like attack sound?

This is way too cool. Damn, you made your own keyboard out of lego parts. Keep doing unique stuff like this. Really cool. 5/5 stars

this is pretty cool! i love it. i dont know how exactly it works, but you could do 2 octaves with you 2. one, which is enough for almost anything

Det er godt arbejde! Det virker lidt indviklet, men jeg forstår vist hvordan det virker :)
