continuous variable .wav sound

Artelius,

Yes, please do modify QB64 to eliminate the delay-per-change.
That would be GREAT! The basis for a truly exciting music prog.

But I am still not sure if we are talking at cross-purposes, for your prog, under mouse control, changes the ENTIRE sound (from one waveform to another): a kind of static change - once per mouse click.

In CONTRAST the numbers generated by my QBASIC are continuously added "at the front end" and get to be played dynamically as part of the changing sound after a small delay (say 1/4 second)

I don't know HOW the various progs that let you copy a sound CD do this - but you can play the music WHILE the copy is being made.

Many thanks for your help and ideas on this
John
