My first program on HP-50g - Music.

[CMarangon]

Hello!

In HP48 I used to do something like store all notes in vars and so recall it from a program.
I think that it also works in HP50.


I store all notes as a var, so recall it from a main program.

For example:

<<440 .1 BEEP>>
STO it in the var "LA"

and do the same for "Re", "Mi", "Fa", "Sol", "La", "Si", sharp, flat and so on.

Exemple of the main program:

<<LA DO DO RE MI FA FA SOL SOL SI SI>>
store it as MUSIC and and so run it.

This avoid you to type everytime the musical note time and frequency, makig the program shorter:-)

Kind regards,

Carlos

1 10 START DUP 0.08 BEEP NEXT DROP »

That makes it run quite a bit faster, it's now better to change the note length to 0.1 to slow it down a little. I guess it will leave less time between beeps, which has to help.
hanks for sharing that trick.
