Requires an Apple IIgs
AmperSound GS is a set of
ampersand (&) commands for Applesoft BASIC that you
can use to access and control the Ensoniq 5503 Digital
Oscillator Chip (DOC) that is the core of the great sound
capabilities of the Apple IIgs. You can create and play
back sound waves at any frequency you choose, even make
music!
AmperSound GS is a fairly simple suite of commands; it
provides individual control over each of the 30 available
oscillators on the Apple IIgs. Normally these oscillators
are paired for finer and more vibrant sound, but
AmperSound GS doesn't do this, so the sounds you can
create are fairly simple waveforms. However, you can
still do quite a bit with it.
Included are several BASIC sample programs, including one
with a reusable subroutine you can use that can play
music using strings representing the musical notes you
wish to play. Documentation on how to use the commands is
included as well.
This program was published by Nibble
magazine back in 1993, some four years after I
submitted it to them. I thought they'd decided not to run
it, and let my subscription lapse literally the month
before it finally got printed. Talk about
timing!
