Subject: Re: Any Libraries for AY-3-8910 (MUSIC!)

I have developed and someday soon (hopefully) will market a S-100 card
with two AY-3-8910s, joysticks, tracballs, clock/calander w/battery
backup, and SSI-263 high tech Speech Synthesizer.  I have demo programs
in ZBASIC (Zenith Z-100) to drive all the sounds (these came from the
AY.. Data Sheets) and MUSIC (I wrote a sheet music hand encoded data
cruncher to AY.. program to pump the AYs with mindblowing music.
I hand encoded Star Wars and the rest I converted from the SIG/M Music-
Composer Data (device used CP/M CPU intensive 4 D/A converters) to
my more humanlly readable data format.  I think they are SIG/M volumes
66-69 (3 disks) +/- a number.  You can get it by FTP from SIMTEL-20.

Unfortunately, I can not release my programs (they are not the greatest
anyway as I know very little about Music) until my device comes to
market and copyrights are canned.

The AY-3-8910 Data Manual is a must if you are to do anything worthwhile
with them.   It also contains equations for register values for a wanted
frequency, wave form stuff and most important a table of all the notes
on a piano and the freq to several places.  I can upload this for you
as I'd hate to have another person on earth have to type it in again.

If you or anyone has any other info on using the AY-3-8910, have any
interesting noises, and/or any computer format music/song data for
any computer music devices please let me in on it.   Thanx

Cheers,
Gern
