MIDI is shareware. This means that you may copy it and give the copies to
anyone you want. It also means that you are requested to send a contribution
if you, or anyone you give it to, uses it. If you give MIDI to a friend, be
sure you give him/her this text file with the program.
Remember - if you're using it, then it is obviously worth something to you,
and a contribution should be made.

If you have any comments or suggestions I'm EDDYR on PAN and BDQ855 on the
Source.
Oh, and how much? Whatever you think is appropriate.
And we thank you for your support...
MIDI
Note: In order to write to the screen as fast as possible, MIDI writes data
directly to the screen memory. This works fine with monochrome and color
display adapters in all Compaq & compatible computers except the old IBM CGA
color card. If you have one of these, the screen will "snow" badly. Sorry -
I can only suggest upgrading to an EGA, VGA, or another brand of CGA card.
Except for the Real Time Commands page in Send Mode, MIDI uses the hex
numbering system. All midi data displayed on the screen is in hex, and all
midi data entered at the keyboard must be done in hex. Most information in
synth manuals about sys-ex messages is given in hex but be careful, SOME of it
is not. At the end of this file is a conversion chart for your convenience.
A memory resident program by Borland International called "Sidekick" has a
calculator that converts numbers from decimal to hex or binary. Be sure to
note the warnings for it's use in the following information about MIDI.
MONITOR MODE
Monitor Mode is used to look at the midi data coming from an instrument. The
Mask Bytes option enables you to have the program ignore and not display bytes
you don't want to see. To remove or enter a mask, press the "?" key - you do
not have to press Shift when doing this. The arrow keys can be used to move
around in the mask display area. Delete a mask by pressing "X" when the
cursor is at the desired byte. You can mask up to five different bytes. When
the masked byte is received, it is not displayed, and all following data bytes
are also masked. When the next status byte is received, if it is not masked,
it and it's associated data bytes will be displayed. Pressing "E" or "8" is a
shorthand way of entering "FE" or "F8". If you make a mistake in entering the
first digit of the byte, the Backspace key can be used to start again. If the
mistake is made on the second digit, you will have to press the "?" key, arrow
over to the byte, and then reenter it. To clear all masks, press "C".
To make the display of data more readable, any byte higher than 7F is
displayed in reverse video (to identify it as a status byte), and 2 spaces are
inserted before it. Pressing "L" will display a list of MIDI status bytes and
what they mean. The "K" key clears the screen and also clears the history
buffer. Pressing "H" calls up the history buffer, which holds 30,000 bytes
max. After the buffer shows 30,000, it is still being updated - so it will
always contain the last 30K received. The History Buffer can be written to
disk as an ASCII file which can then be printed. Don't call up any memory
resident programs like Sidekick while in the monitor screen. If you need to
do so, press "L" to call up the MIDI list, or "H" for the history buffer
display, and THEN call up Sidekick.
SEND MODE
Send Mode is used to find out how equipment will respond to various midi data.
The loop repeat can be used to constantly send a small sequence for trouble
shooting and testing. Use spaces for delays. You can enter up to two lines
of data. The "G" key retypes the last line(s) that were entered. The "U" key
allows you to send a "dump request" and then view the response in Monitor
Mode. Just type in the request, complete with F0 at the beginning and F7 at
the end, and then press "U". The request will be sent and you will be
immediately put in Monitor Mode to view the response, with FE and F8 masked.
Of course the response can then be viewed in the history buffer and printed if
desired. Some synths will respond to a dump request without the F7 at the
end.
It takes two hex characters to make a complete byte. If an odd number of hex
characters is entered, the last single character won't be sent. If you press
"U", the entry area will be blanked and you won't be put in Monitor Mode. If
this happens, press "G" to retype the entry, correct it, and then try again.
Don't call up any memory resident programs while in this screen either. Press
"L" first.
The Real Time Commands screen has more options for sending data, including
MIDI clock and associated commands. The only time the MPU is allowed to send
MIDI clock bytes is when you are in this screen.
PATCH MODE
Patch Mode consists of several subsections for dealing with saving and
transmitting bulk patch or sequence data that is in the standard "System
Exclusive" format.
When you first enter Patch Mode the screen shows an alphabetical listing of
all the files on the disk or current subdirectory. The maximum number of
files that can be displayed is 114. If there are more, they will not be
displayed and a message will appear to inform you of this condition. As files
are added, deleted, or renamed, the directory will be updated. You will
notice that the name of this program (MIDI.EXE) is not displayed. This is
done on purpose to save space for voice bank listings. DO NOT use this name
for any bank names. Memory resident programs can be called up when in Patch
Mode except when receiving or transmitting data.
The "Receive" option will save System Exclusive dumps from midi instruments.
When you press "R", you are given the choice of initiating the dump from the
instrument or sending a "dump request". Some common dump requests are listed
on the screen along with instructions for entering the request. If you elect
not to send a dump request, the computer is immediately put in sys-ex receive
mode and is waiting for data. As data comes in, small musical notes will
appear between the braces in the upper left portion of the screen. When the
notes are gone, the "W" key should be pressed to write the data to the disk.
This is a separate operation so that separate bulk dumps from one or more
instruments can be saved to one file. Just keep initiating bulk dumps until
you are done, then press the "W" key. The buffer in memory that holds the
data before writing to disk can hold 131,070 bytes. A switch in the SPX-90
has to be changed which makes the thru jack an out jack in order to use the
special SPX-90 dump request.
The "Transmit" option transmits the system exclusive files back to the
instruments. You have a "block-at-a-time" choice here in case you have saved
several instruments to one file and need time between each "send" to connect
the proper instrument to the computer. If the instruments are all different,
they can be fed the file non stop. Each instrument will respond only to it's
particular sys-ex message.
The "Rename" and "Delete" options are self explanatory. Delete does not ask
if you are sure before deleting so be careful.
The "File Size" command lists sizes of sys-ex dumps of various instruments.
This is for checking data integrity after a patch dump is received.
The "Echo ->" toggle turns the "thru" function of the midi interface on or off
for the patch mode only. Whenever you enter this screen, it is initially
turned off.
Enjoy !!
