THE MUSIC CORNER by Frank Lemmen
Hi, Music freaks, here I am again with The Music Corner, the
easiest way to get into touch with the professional world of
computer-driven music synthesis.
Remember me promising you a program to manipulate the Casio CZ-
230S built in drum computer in the previous issue of ST NEWS? I
know some of you expected a full-sized drumcomputer with editing
possibilities, mixing and the whole riff-raff, but I do not seem
to remember having promised you anything like that (I was
cautious, you know). I had a good look at the MIDI software
possibilities of controlling the drum computer in my synth, but
alas! I found out that the whole goddamn thing could not be
controlled by means of software only...Imagine the buttons going
up and down on the CZ by using a PEEK or POKE (or even an OUT or
INP)?!?!
So the program that I hereby offer only allows very basic
(speed) manipulation of the drumcomputer in the synth (sorry, but
I couldn't make more of it due to the sheer lack of software
possibilities of the CZ).....
Here, you will find the program, which is also added on the ST
NEWS disk in the PROGRAMS folder with the name "DRUMCOMP.BAS". I
am very sorry that I couldn't make more of it, but by means of
this article and the accompanying program I hope to have given
you at least some small tips & tricks on using MIDI synthesizers
and their built-in possibilities on the Atari ST using GfA Basic.

That's all folks! Next time, I hope to offer you another more or
less useful routine (and, if I get awfully bored sometime, maybe
several routines!) for working with the ST and MIDI. If you
happen to have any interesting routines up your sleeve, on some
partition of your hard drive or some clusters on a forgotten
floppy, please do not hesitate to contact me at my address which
is revealed to you in the "Pro Sound Designer" review, elsewhere
in this issue of ST NEWS. See you later (alligator)!
