Cool. Just to check, this just plays a note 3 times for 2 seconds each right, almost the same as playing it for 6 seconds?

PLAYQB "T120MLO2L1Eee"

I liked the other sound strings.
To me they sound better as square waves than sine waves though.

Nice work Jim
I had been looking at the QBasic PLAY command and wondering how to port something similar

Yes
It was a test to make sure that there was no audible gap between notes.
I also think that there was a maximum play time for individual notes.

I wrote these functions 10 months ago and forget some of the sources.
Most of the QB ones come from "Gorilla", something that I started converting and will get back to sometime.

"GORILLA.BAS" classic QBasic game. I was looking at doing Reversi/Othello

Good work with the sounds stuff Jim
