It's not really done that way. The "notes" are standard note frequencies. The program stores 21 "notes" as decimal values that are loaded into a DAC to produce the required voltage to cause the VCO to oscillate at the required frequency. This version is in the key of C major. The data is below. If you look at the list of values for tone data the first is "G1" the next is "A1" and the next is "B1" then "C2" and so on. Given that, the notes of the song are: C3, C4, B3, G3, A3, B3, C4,C3, A3, G3, A2, F3, E3, C3, D3, E3, F3, D3, B2, C3, D3, E3, C3. In any case, if you can read music just google "over the rainbow sheet music". You will find many versions. The version up on Musescore is in C major and likely you can downlead it for free. : Tone data : Value to send to DAC : 1000 DATA 34, 38, 42, 44, 50, 55, 59, 66, 74, 82, 87 1010 DATA 99, 112, 118, 131, 149, 166, 174, 199, 226 1020 DATA 239 : Song Data : In Pairs.

You stole my copyrighted ray-gun sound! I'm gonna sue! :) BTW, I'm building a full Piia synth kit for a friend. I still have a couple of weeks of 6 hour days left on it.
Pretty cool. Thanks.
Glad you liked it!
Great fun !...cheers
Thank you! Cheers!
I think the white solder mask with black ink makes PCB assembly easier.
Yes, it really does. Every component just pops out.
do you have over the rainbow notes/freqs where you can post it or whatever? Thats my favorite song

Very cool! Do a video on it and show it to us .. please!
