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!
