In the Kernel32 decls, there is a command called api_Beep, which allows pesiospeaker access. I need some tunes for the pesio. I'm thinking of eventually making a pesio media player for the C64 junkies out there. I would really like the pesio frequencies for the Star Spangled Banner, which google cannot find. Also, is there a way to translate MIDI to frequencies?

If you are still looking, I can post frequencies to notes and then you can simply transpose the sheet music of the star spangled banner.

I've heard mps/mod/wav and midi played thru the speaker before so I know it can be done. the thing I wonder about is that I think the pc speaker can only output a single voice and the c64 had 3 voices. I am not sure what type of speaker is in new pc, pc/jr and tandy1000 had a 3 voice speaker original pc speakers only had a single voice.
