- Preface
-
-
- This document describes the program MCZ. It is assumed that
- the reader is reasonably familiar with the operation of the
- CZ series sythesizers, and PC-DOS or MS-DOS.
-
-
- Overview
-
- MCZ is a basic MIDI support program for the CZ series of
- digital synthesizers. MCZ enables you to:
-
- - create, edit, and manage patches and patch libraries.
-
- - download into the CZ a single patch or a list of
- patches.
-
- - upload a patch from any CZ memory.
-
- - Record and play back up to sixteen MIDI tracks.
- Individual tracks can be saved and retrieved from
- disk.
-
- - Trace all MIDI data received by the MIDI interface
- card.
-
- Most MCZ functions are tailored for use with the CZ.
- However, the non-CZ specific functions should work with any
- MIDI device.

-
- Summary of Changes in Version 1.1
-
- A bug in the modulation setting code was fixed.
-
- A directory and index function was added to the opening
- screen of the patch editor. Using the DIR function key shows
- you all of the patch libraries in the designated DOS
- directory/subdirectory. The INDX function key shows you the
- index of patches in a designated patch library.
-
- Patches can be printed from the patch index screen by using
- the PRNT function key. The printed result can be directed to
- a printer or any DOS file. The new Administration option on
- the main screen can be used to designate an output device or
- file. The format of the printed patch is very suitable for
- machine processing by C programs.
-
- An autoload function is added to the patch editor. Selecting
- the autoload function toggles it ON and OFF. When ON, the
- patch you are editing will be downloaded every time you make
- a change to it.
-
- The GET function is added to the envelope editor. It lets
- you "get" an envelope from another patch or the current
- patch. Using GET, you can do things like copy DCA-1 from
- patch X to DCW-2 of patch Y.
-
- System Requirements
-
- MCZ was designed to run an an IBM PC, XT, AT, or compatible.
- Approximately 128K of memory is required for basic operation.
- Both monochrome and color displays are supported. MCZ
- supports the MIDI interface designed by Jay Kubicky. This
- board is described in the June 1986 issue of BYTE magazine,
- p.199. It can be built for about $75.
- Getting Started
-
- MCZ can be started by entering the command MCZ at the DOS
- prompt:
-
- d> MCZ
-
- This example assumes that MCZ is on the current disk, or that
- is is accessible through the current path.

- Keyboard Usage
-
-
- This section describes how the keyboard is used to interact
- with MCZ.
-
- MENUS/SELECTION LISTS
-
- When a menu or selection list is displayed, the following
- keys work as described:
-
- Down arrow - move to selection below.
- Up arrow - move to selection above.
- Enter - take the default action on the current
- selection.
- Tab right - next selection to right.
- Tab left - next selection to left.
- Right arrow - next selection to right.
- Left arrow - next selection to left.
- Function keys - designate actions as shown at the bottom
- of the screen.
- Escape - abort and return to previous screen.
- Enter - take the default action on the current
- selection.
-
- Like many PC programs, selections can also be made by typing
- the first character of the desired choice. When more than
- one selection starts with the same character, the first one
- from the top of the list will be chosen.
-
- FORMS/DATA ENTRY SCREENS
-
- When a form is displayed, the following keys work as
- described:
-
- Down arrow - move to field below.
- Up arrow - move to field above.
- Enter - act on the data.
- Tab right - next field to right.
- Tab left - next field to left.
- Insert - insert keystrokes in field.
- Delete - delete character at cursor.
- Right arrow - move cursor right one character.
- Left arrow - move cursor left one character.
- Ctrl-End - delete to end of field.
- Function keys - designate actions as shown at the bottom
- of the screen.
- Escape - abort and return to previous screen.
- Enter - data entry complete.

-
- Patch Library Names
-
- Patch library names may be up to 8 characters in length. MCZ
- arbitrarily appends a ".LIB" to a library name to form a full
- DOS file name. For example, the library "CZLIB" will appear
- as the DOS file "CZLIB.LIB". The format of a library file is
- described in an appendix.
-
- Whenever a library name is required, it may be entered with
- leading directory information. Continuing with the above
- example, assume that CZLIB is in the directory "A:\CZ". Then
- the specification "A:\CZ\CZLIB" correctly designates the
- location of CZLIB. Generally, 32 characters are allowed for
- the specification of a library name.
-
-
- Patch Names
-
- Patch names may consist of any characters on the keyboard.
- MCZ does not check a patch name for validity. Up to 28
- characters may be used to name a patch.
-
-
- Patch List Names
-
- Patch list file names are given just like patch library
- names. MCZ appends a ".TL" to a patch list name to form a
- full file name. For example, creation of a pathc list named
- INTERNAL will produce a file named INTERNAL.TL.
-
-
- The Main Menu
-
- The main menu is where the action starts. From it, you can
- select patch management, patch list management, MIDI
- recording, and other MCZ functions.
-
-
- Managing Patches and Patch Libraries
-
- MCZ provides all of the functions that you will need to
- create and maintain libraries of patches. You can:
-
- - create a new patch library
- - view the table of contents of a library and select a
- patch for action.
- - create a new patch, from scratch or from an existing
- patch.
- - delete a patch from a library.
- - rename a patch.
- - edit patch data.
-
- To access patch management functions, select "Patch
- Management" from the main menu. You will be asked to enter a
-
-
-
-
- MCZ 1.1

-
-
-
-
- patch library name. If the library exists, MCZ will display
- its index (table on contents). If the library is new, MCZ
- will ask you for a patch name and you will be placed in the
- patch editor. From the library index, you take management
- actions by pointing/selecting a patch and designating the
- action via PF keys. The ENTER key takes the default action,
- which is to edit the patch.
-
-
- MCZ comes with a patch library named CZ1. It contains many
- patches found in the Casio "Sound Data Book."
-
- Using Patch Lists
-
- A patch list is a convenient way to deal with the CZ's patch
- memories. A patch list identifies up to 16 patches. Each
- entry in a patch list names a library and a patch from that
- library. You can download a patch list into a CZ memory
- area. For example, on the CZ-101, you can load a cartridge
- by making a patch list and downloading the list to the
- cartridge.
-
- You enter the list editor by selecting "List of Patches" from
- the main menu. MCZ will ask you for list name. After you
- enter the name, MCZ will show you the list and allow you to
- change it. A patch library name need not be repeated for
- each memory. An "=" indicates the last explicitly named
- library. List creation is simplified by using the "Indx"
- action. This action shows you the library index for a
- library. When you "Pick" a patch from a library, MCZ copies
- its name into the list. This allows you to have meaningful
- patch names without the tedium of having to re-type them.
-
- MCZ comes with a patch list file named INTERNAL. It
- illustrates how to set up a patch list.
-
- A patch list can be loaded by selecting "DownLoad" from the
- main menu. You will be prompted for a patch list name.
- After you enter the name, the list will be loaded into the
- designated CZ memory.
-
- MIDI Recording and Playback
-
- MCZ includes a basic MIDI track recorder, specifically
- designed for recording CZ MIDI data. Using the
- recording/playback facilities, you can:

-
-
-
-
- - set the size of a track, within the limits of
- available memory.
- - designate a single record track and multiple playback
- tracks.
- - record/playback designated tracks.
- - save recorded tracks in a file.
- - load a designated track from a saved file.
- - set the record/playback tempo.
-
- Digital recording functions can be accessed by choosing
- "Record/Playback" from the main menu.
-
-
- MIDI Tracing
-
- If you are interested in seeing the raw data that comes from
- a MIDI device, you can use the trace facility. It displays
- each data byte, in hex, as it is received over the MIDI
- interface. This function is extremely useful for
- understanding what kind of data your MIDI device produces
- when you interact with the device.
-
-
- Appendix 1: Patch Library Format
-
-
- The first 32 bytes of a LIB file are used by MCZ and are not
- of general use. The rest of a LIB file consists of one or
- more patches with a very simple format. Each patch consists
- of a name and patch data. The patch data can be loaded into
- the CZ by simply "nibblizing" it. Nibblizing is the process
- of sending a byte of data as two bytes, so data bytes don't
- conflict with MIDI status message bytes. For example, the
- data byte ABh is sent as the two bytes 0Bh, 0Ah.
-
- Patch format:
-
- Offset Length Data
-
- 0 32 Patch name, zero terminated
- 32 128 Patch data
