Alright, so, "back in the day" I programmed a lovely music player in BASIC, which later upgraded to QBASIC, and was eventually compiled with Quick BASIC. Because of the way the sound was produced (using the BASIC "play" command), I was able to control the music tempo, key, etc. using some fairly simple subroutines. My music program would play any one of several hundred hymns that I programmed into it, and each was user-selectable for any key or tempo within a certain range. So, if "Amazing Grace" were written in the key of C but a bass singer wanted it transposed to E
b, no problem. Want that song a little faster? Can do!
I've never seen any "modern" music player match that. Can an mp3 player, for example, transpose the key for you?
Like you, dbw, I question if this is even possible on the modern hardware and software. I know for a fact that Visual Basic (the logical upgrade for Quick BASIC), does NOT have music capability. That has frustrated me to no end. All it can do is a pitiful beep. But then, is Perl any better?
