1.1 Configuration
The MZ-2000 is made up of a Performance Block and a Sound Source Block as shown below.
The Performance Block includes the keyboard, wheels, and other real-time controllers, as well as
auto accompaniment, the sequencer, the control panel, etc.
The Sound Source Block consists of a Common Sub-block that includes tone generator settings,
effector, and mixer, and a Parts Sub-block that includes a 32-tone tone generator.
* Performance Block
o Keyboard
o Wheels and other real-time controllers
o Auto accompaniment
o Sequencer
* Sound Source Block
o Common Sub-block
+ Tone generator settings
+ Effector
+ Mixer
o Parts Sub-block
+ Parts that cannot be received by the tone generator (Parts 1 to 16)
+ Parts that can be received by the tone generator (Parts 17 to 32)
1.2 messages and Channels
1.2.1 Performance Block
The Performance Block generates messages for keyboard, wheel, pedal and other real-time controller operations, and for the sequencer, auto accompaniment, the control panel, etc. messages for
each type of operation are sent both to the sound source and to the MIDI OUT terminal. Though
the Performance Block has only send functions, it also performs chord recognitions when note
data is received.
Send message channel numbers are in accordance with the MZ-2000 send (Tx) channel settings.
Accompaniment part send messages are sent when the MZ-2000 Accomp MIDI Out parameter is
turned on.
1.2.2 Sound Source Common Sub-block
The Common Sub-block consists of a tone generator for tones that do not depend on in the sound
source, an effector, a mixer, etc. The settings of these items can be changed by system exclusive
messages or by channel messages with channel numbers set by the MIDI Global Channel.
1.2.3 Parts Sub-block
Operation and setting changes of the Parts Sub-block of the Sound Source Block can be controlled
using system exclusive messages and channel messages. Channel messages used for such control
are limited to those with channel numbers set by the MIDI channel assigned to the applicable part.
Also note that Parts 17 through 32 only can receive channel messages.
2 Channel messages
The channel numbers of the channel messages received by each part are in accordance with the
MZ-2000 receive (Rx) channel settingfor each part. Channel messages are not received for any
part whose receive channel setting is off.
When the MZ-2000 MIDI In Chord Judge option is turned on, MZ-2000 auto accompaniment
chords can be specified using note messages within the chord judge keyboard range specified by
the MZ-2000 by sending the note messages over the channel that is specified as the receive channel for Part 1.

System exclusive messages received by the MZ-2000 sound source start with the following data.
Format
F0H 44H 7EH 02H 00H .... 7FH
Though the purpose of system exclusive messages is mainly to assign parameters, the MZ-2000
also sends system exclusive messages whenever an operation that changes the setting of a parameter is performed.
A system exclusive message also includes a Device ID value, which corresponds to the channel
number of a channel message. A Device ID is used when a system exclusive message is sent.
You can change the Device ID value on the MZ-2000.
See "4 MZ-2000 Sound Source System Exclusive Messages" for full details on MZ-2000 sound
source system exclusive messages.
4 MZ-2000 Sound Source System Exclusive Messages
4.1 MZ-2000 Sound Source Common System Exclusive Format
4.1.1 General
The MZ-2000 sound source consists of audio signal processor sections for the tone generator,
effects, mixer, etc.
The MZ-2000 sound source sends and receives sound source-related system information, parameters, and parameter sets, using the format described later in this chapter.
The format consists of a header block and data block. The same header block is always used
within the MZ-2000, but the format of the data block is determined by the data being communicated.
The data content, in turn, depends on the MS-2000 function. The following sections of this chapter provide detailed information about the data content for each function.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Header Block (Hexadecimal)

03 02 [Model ID LSB] MZ-2000 Sound Source Model-ID LSB
04 00 [Message Version]
05 ** [SysEx Dev ID] SysEx Device ID 00H to 1FH,7FH (Default: 16)
Even with system exclusive messages, channel numbers can be specified within the
range of 00H to 1FH for use as a Device ID number.
Messages are ignored if their ID Device ID number does not match that of the MZ-
2000.
A Universal Device ID of 7FH is provided, which means that the MZ-2000 always
recognizes any SysExc message with a Device ID of 7FH.

(nn < 256) Indicates there are 256 data bytes or less from F0H to F7H.
4.1.2 MZ-2000 Sound Source Common System Exclusive Data Blocks
The MZ-2000 sound source system exclusive data block always starts with the message type,
which indicates the type of communication is being performed. Messages can be broadly classified into the types listed below.
* Individual Parameter Send/Receive
* Individual Parameter Send Request Send/Receive
* One-Way Parameter Set Bulk Send/Receive
* One-Way Parameter Set Bulk Send Request Send/Receive
* Handshake Parameter Set Bulk Send/Receive
* Handshake Parameter Set Bulk Send Request/Receive Rejection/ Error Report Send/Receive
With one-way communication, the sender sends the data and immediately ends the session without any response from the receiver. This type of communication is best for one-way data transfer
from a sequencer, etc.
With handshake protocol, the sender sends the data but does not advance to the next session until
it receives a response from the receiver. This type of communication helps to reduce time wasted
waiting for the receiver to become ready.

4.1.3 Parameter Configuration
A parameter is a variable for making sound source operational settings, while a parameter set is a
group of multiple parameters.
When using the MZ-2000 sound source system exclusive messages to access parameters and
parameter sets, you must specify the location of data you are trying to access. The following
shows the location of each type of data.
* Category (4 bits) ....Parameter set category
* Type ID (7 bits - 7 bits).....ID number inside parameter set category
* Mdev ID (7 bits - 7 bits) ..... ID number of memory where parameter set is stored
* Section Number (14 bits) ..... Section number indicating where a parameter set is stored in
memory
* PS (Parameter Set) Number (14 bits)....Number indicating where inside a section a parameter
set is stored
* Parameter ID (For parameter specification only)(16 bits) ....ID number of a parameter inside a
parameter set
* Parameter Block Number (For parameter specification only) (7 bits* 1 to 16)
....Block number to which a parameter is attached inside a parameter set
In a structure where parameters with the same parameter ID are assigned to multiple blocks
within the same parameter set, the block numbers must be specified specified using at least one
as as many as 16 array data items.
The parameter blocks of the sound source parts and key numbers are a typical example of this.
When there are parameters with the same ID for the key numbers in each part, a single parameter can be specified to substitute the part number and key number for at least one of the Block
Number arrays.
Exactly how many of these values there are is covered within the explanations for each parameter.
There are two parameter formats, depending on the parameter ID: single data and array data.
Array data is sent by specifying the starting element and the number of elements to be sent.

4.1.4 Individual Parameter Operations
This section describes parameter operation formats.
IPR Communication Flow
A session consists of an IPC being sent in reply to an IPR request, or an IPC being sent and the
session being terminated with without a request.
When the MZ-2000 receives an IPR, it returns the corresponding parameter IPR.
When the MZ-2000 receives an IPC, it changes the value of the corresponding parameter.

4.1.5 Parameter Set Bulk Dump
This section describes the bulk format for parameter set transfers.
How parameter sets are actually allocated depends on the MZ-2000 sound source specifications.
See sections 4.2 thorugh 4.11 for more information.
Unlike the data format for individual parameter changes, a memory image is sent in order to
increase the speed of the parameter set bulk dump. Pre- and post-processing required for each
parameter is performed after bulk dump of all the data is complete.
You can transfer multiple parameter sets during a session. When a single parameter set is very
large, it can be divided and transferred as multiple packets. In such a case, and address offset is
included as part of the data.
Transferring multiple small-size parameter sets using a single packet is not allowed. Each parameter set must always be transferred as a separate packet.
One-Way Communication Flow
A session starts with a BDR request by the data receiver or a BDS data send by the data sender.
The session ends after the data sender transfers the required amount of data for the number of
parameter sets.
When the MZ-2000 receives a BDR, it uses a BDS to return the corresponding parameter set.
When the MZ-2000 receives a BDS, it modifies the setting of the applicable parameter set.
Data is divided into packets of 256 bytes or less and transferred at fixed intervals (20 msec).

HDJ is sent whenever the session is terminated for any reason. HDJ can be sent from either the
sender or receiver. Receipt of HDJ immediately terminates a bulk dump.

A session starts with the data receiving sending an HDR request or an HDS data send from the
data sender.
The data sender does not send the next packet until it receives an acknowledgement (ACK) from
the data receiver. Be sure to reserve at least 100msec as the maximum wait time. If no response is
received within the prescribed time, a time out error occurs and communication is terminated.
If the data receiver returns an HDE (error) due to a checksum error, illegal data format, or any
other reason, the data sender resends the data. Resend the data at least one time.
The session ends after the data sender transfers the correct amount of data for the number of
parameter sets, and is terminated when an ACK is returned.
