In the April 1984 Issue of RUN mag.
there was an article about using the
SID on the C-64. There was also a small
article called "Playing with SID" that
gave some details about how to go about using a HES Sound Box connected to the
A/v Port (so you can access pin#5) to
to get SID to accept external signal input.
From Page 50 of April 1984 issue of RUN:
"The following program tells you how to access the SID chip to read external
input. These are only opening values,
though, so you'll still have to do some book work
to find out how to set the filters up
and how different values will affect the
sounds you produce. But it's a start,
and a good one at that.
10 SID=54272
20 POKE SID+23, 128+8
30 POKE SID+24, 32+15
40 POKE SID+22, 128+2 "
If anyone has done this or can provide
with more information about inputing
from an external to SID, please reply by mail.
Thanks in advance.
