File : README.TXT 10 July 90
for SBK V1.03


This file contains the latest information which was not yet
available when the manual was printed.


1. Disk Contents


\BIN : executable utilities and drivers
\QBASIC : include files, quick library and example
programs for QuickBasic
\CMF : sample CMF files

In the QBASIC directory, the following sub-directories
are set up :

INCLUDE : include files
LIB : libraries
VOICE : examples for using CT-VOICE drivers
MUSIC : examples for using the SBFMDRV driver
SPEECH : example for using the SBTALKER driver



3. SBK Version


To assist you in determining the version of the SBK library that
you are using, the following files are supplied in the QBASIC
directory. When they are compiled and run, the SBK library
version will be displayed. This will be very useful when you
contact us for technical support.

QBASIC\SBKVER.BAS



4. Voice and Music Files


The voice and music files, viz DEMO.VOC and FFARES.CMF, used in
the QuickBasic example programs are to be found in the root
directory. They are fairly big files and this is done to save
disk space.




5. For QuickBasic Programmers


In the example programs for handling voice I/O, large memory
buffers are required and they are created as Dynamic INTEGER
arrays. If any of the arrays takes more than 64KB of space or it
has more than 16384 elements (since each integer takes 4 bytes),
then you must invoke QuickBasic with the /ah command option as
follows :

QB /ah
or
BC /ah .......



6. New MIDI Control Change Events.


With SBFMDRV Driver Version 1.02 and above, 2 new MIDI Control
Change Events are added. Also refer to page 4-8 in the SBK
Manual.

Control Number Control Data

68 hex 0 - 127

change the pitch of all following notes
upward by the specified number of 1/128
semitone.

69 hex 0 - 127

change the pitch of all following notes
downward by the specified number of 1/128
semitone.

For instance, if the Control Data is 64, the pitch is changed
by half a semitone. If the data is 0, then the pitch change is
cancelled.
