What is Beebsynth? Having played with it for hours, I can safely say I think it's two programs
for the price of one - a rare event these days.
The first part is a utility to help you design sounds for inclusion in games, or for use in the
second part of the program. You can change all the parameters of the sound envelope either singly
or in steps of ten, and when you've got the effect you want, see the command to produce it
displayed at the top of the screen.
The second part turns your micro into a music keyboard. I spent many happy hours trying it out
and annoying the dog with a selection of high-pitched discordant musical sounds. As for a
more musical friend of mine, his reaction to the wildly varying possible sound combinations was
only tempered by the restrictions of the keyboard layout.
