individual parameter, and Parameter Set type for bulk send and receive of a set of
parameters.
These SysEx types can be further broken down into parameter categories according
to the item being transferred.

The operation type of a message is determined in accordance with the value of the
"Action" field of the CTK-671 SysEx message. The basic format for all operation type
messages is described in "2.1.2 Message Structure," below.
2.1.2 Message Structure
The CTK-671 System Exclusive Message Format is formed using the 14 fields described
below.
Whether or not a particular field is included in a message and the length of each field
depends on the message.
SYSEX MAN MOD dev act/cat prm ilen/dlen ps <index> <data> <sum> EOX
---------- ------ ------- ----- ---- ---- ----- ---- ----- ---- ---------- --------- --------- ------
1 2 3 4 56 78910 11 12 1314
The act field describes the action that the message performs. The meanings of the <index>
and <data> fields differ according to the value of the act field. The following describes
each of the fields in detail.
1 .......SYSEX : System Exclusive message Status
Format : 11110000
System Exclusive message Status = F0H
2 .......MAN : Manufacturer's ID
Format : 01000100
CASIO Manufacturer's ID = 44H
3 .......MOD : Model ID
Format : 00010001, 00000001 (MSB, LSB)
This field contains a two-byte value (MSB, LSB) that indicates the keyboard model ID.
CTK-671 Model ID MSB = 11H
LSB = 01H
4 .......dev : MIDI DeviceID 00H - 1FH,7FH
Format : 0ddddddd
The contents of this field in a received message are compared with the CTK-671
MIDI Device ID, and the incoming message is recognized only when the two IDs
match.
The default value for this field is 10H.
When a message containing 7FH is received, the message is always recognized
regardless of the CTK-671 ID setting.
MIDI Device ID is a Patch Parameter data item, and it can be changed using a
System Exclusive Message. In such a case, the Device ID of the MIDI System
Exclusive Message must be set to 7FH before it is sent.
5/6 ....act/cat : Action/Category
Format : 0aaacccc
aaa = Action (3bit)
This field indicates the action being performed by the System Exclusive Message.
0H.....IPC Individual Parameter Change
1H.....IPR Individual Parameter Request
2H.....BDS Oneway Parameter Set Bulk Send
3H.....BDR Oneway Parameter Set Bulk Request
4H.....HDS Handshake Parameter Set Bulk Send
5H.....HDR Handshake Parameter Set Bulk Request
6H.....Reserved
7H.....HDA,HDJ,HDE,NOP Communication Control (for Handshake)
cccc = Category (4bit)
Categories indicate the type of data handled by the System Exclusive Message.
The Model ID numbers on the left correspond to the categories, and the applicable
communication operation (Action) is shown on the right.
ID Action
c Category act = 0 1 2 3 4 5 6 7

BH.... Rhythm Pattern - - A A A A - A
CH ...Registration - - A A A A - A
A ......Available
- ....... Not Available
7 .......prm : Parameter ID
Format : 0ppppppp
The Parameter ID field indicates the parameter type.
See the "Parameter List" below for details about parameter types.
When transferring individual parameters individually (as opposed to bulk transfer),
this field is used to identify the parameter by its parameter ID.
In any other case, this field is filled with the value 00H.
8/9 ....ilen/dlen : index length / data length
Format : 0iiddddd
This field indicates the size of the subsequent <index> field (11) and <data> field
(12).
The index length (ii) indicates the index field length, which is always the following,
regardless of the act (action) value.
ii : index byte size - 1 (3 when index is 4 bytes)
ddddd indicates the size of each data unit (parameter) of the <data> field.
In the case of the Request and Control messages, which do not contain any data,
this value becomes 0.
• When act = 3(BDR), 5(HDR), or 7(Control)
ddddd .... 0
• When act = 0 (Individual Parameter Change)
ddddd: data bit size - 1 (00000 when data is 1 bit; 11111 when data is 32 bits)
• When act = 2 or 4 (Parameter Set Bulk Send)
16-bit unit transfer, always as shown below.
ddddd .... data bit size - 1 = 01111

9
CTK-671 MIDI Implementation
10 .....ps : Parameter Set Number
Format : 0nnnnnnn, 0mmmmmmm (LSB, MSB)
This field is a 2-byte (LSB, MSB) value indicating the Parameter Set number
(00mmmmmmmnnnnnnn) being transferred.
11 .....<index> Parameter Index Number (option)
• When act = 0 (IPC) or 1 (IPR)
This field contains a supplementary number that points to data when parameters
are arrayed.
An <index> can be anywhere from one to four bytes long, and its role is defined on
a case-by-case basis in accordance with the category indicated by cat and the
song number indicated by Parameter ID.
In the case of preset number, part number, and key number parameters that all
have the same ID, for example, these <index> values would be used to specify
each of the parameters.
• When act = 2 (BDS) or 4 (HDS)
In this case, <index> is a 3-byte fixed field that shows a packet number (sequential
number starting from 00) identifying the packet into which the Parameter Set is
divided for transfer, and the size of the <data> field that follows the <index> field.
i[0] ... 0nnnnnnn Packet Number LSB (NNNNNNNnnnnnnn = Packet Number)
i[1] ... 0NNNNNNN Packet Number MSB
As explained in the <data> field section, 128 bytes can be send per
packet, so received data can contain <Parameter Set start address> +
<Packet Number> * 128.
i[2] ... 0LLLLLLL data length / 3
As mentioned in the explanation of the <data> field, the length of the
<data> field is always a multiple of 3, so the length value is divided by 3.
• When act = 3 (BDR) or 5 (HDR)
This field is always empty.
• When act = 7 (HDA, HDJ, HDE, NOP)
In this case, the <index> field length is fixed at 1 byte, and it indicates the control
messages used for handshaking as shown below.
See "Bulk Dump" for information about this operation.
i[0] = 0000cccc
cccc Control Message
------
0000 EOD Oneway/Handshake Bulk Dump End of Data (End of Data)
0001 HDA Handshake Bulk Dump Acknowledge (Handshake Data Receive
Successful)
0010 HDR Handshake Bulk Dump Reject (Handshake Data Rejected)
0011 HDE Handshake Bulk Dump Error (Handshake Data Error)
:
1111 NOP (No Operation)
12 .....<data> Parameter Data (when action = Parameter Change/Send)
• When act = 1 (IPR), 3 (BDR), 5 (HDR), or 7 (HDA, HDJ, HDE, NOP)
This field is always empty.
• When act = 0 (IPC)
Indicates the parameter itself. The length varies in accordance with the data size
indicated by the dlen field, as shown below.
This field is not included in a parameter request.
ddddd + 1 <data> fields
-----------------------------------+---------------------------
1 - 7 1
8 - 14 2
15 - 21 3
22 - 28 4
29 - 32 5
Each block of data is packed from the lowest order byte first. In the case of multiple-
byte data, the lowest weighted bit is the LSB of the first <data> block, and the
highest weighted bit is the MSB of the final <data> block. The following shows an
example of how data would be divided for transfer in the case of 32-bit data.
7 6543210
----------------------------------------------------------------------------------
data0: 0 [bit06] [bit05] [bit04] [bit03] [bit02] [bit01] [bit00]
data1: 0 [bit13] [bit12] [bit11] [bit10] [bit09] [bit08] [bit07]
data2: 0 [bit20] [bit19] [bit18] [bit17] [bit16] [bit15] [bit14]
data3: 0 [bit27] [bit26] [bit25] [bit24] [bit23] [bit22] [bit21]
data4: 0 0 0 0 [bit31] [bit30] [bit29] [bit28]
• When act = 2 (BDS) or 4 (HDS)
When a bulk data transfer operation is performed, the Parameter Set data to be
transferred is read sequentially in 16-bit units starting from the top address. Read
valuesare divided into 3-byte segments as shownbelow, and thensent in sequence.
The following is the conversion format, which is the same as individual parameter
16-bit transfer explained above.
Memory Image 16 bits
MSB: abcccccc
LSB: cddddddd
<data> Field 3 bytes
data0: 0ddddddd
data1: 0ccccccc
data2: 000000ab
Note, however, that a Parameter Set of 128 bytes or less can be sent using a
single packet, and anything greater than 128 bytes is divided among multiple
packets.
This means the maximum length of a <data> field is as shown below.
128/2 * 3 = 192 bytes
Only one Parameter Set can be transferred per session, and data from different
Parameter Sets cannot be mixed within a single packet, even when sending multiple
Parameter Sets.
Different Parameter Sets are always divided into separate packets.
13 .....<sum> Check Sum
• When act = 0 (IPC), 1 (IPR), 3 (BDR), 5 (HDR), or 7 (HDA, HDJ, HDE, NOP)
This field is always empty.
• When act = 2 (BDS) or 4 (HDS)
In this case, the <sum> field contains a value, which, when added to the total
value of the <data> field, makes the lower seven bits 0.
The receiving side checks if this is true, and performs error handling (re-request,
etc.) if it is not.
14 .....EOX : End of System Exclusive Message
Format : 11110111
End of System Exclusive message Status = F7H
2.2 Individual Parameter Operations
There are two individual parameter operations: Individual Parameter Transfer and
Individual Parameter Request.
During a single session, an Individual Parameter Request (IPR) can be responded to by
returning an Individual Parameter Change (IPC) or by simply sending an IPC.
Receipt of an IPR causes the corresponding parameter IPC to be sent back.
Receipt of an IPC causes a change of the corresponding parameter value.
An Individual Parameter Change can also be used to issue some command to the CTK-
671, and the Individual Parameter Request can be used to check CTK-671 status
information.

See "Parameter List" in this document for information about which parameters can
actually be sent.
2.3 Parameter Set Transfer Modes
2.3.1 Communication Modes
Parameter Sets can be transferred by bulk dump, using the types of message exchanges
described below.
• One-way mode Parameter Set send/receive
• One-way mode Parameter Set send request send/receive
• Handshake mode Parameter Set send/receive
• Handshake mode Parameter Set send request, receive rejected, error notification send/
receive
With the One-way mode, the sending device sends data and ends the session without
paying any attention to the response of the receiving device. This mode is best for one-
way transfers from a sequencer or similar device.
With the Handshake mode, after the sending device sends the data, it confirms response
from the receiving device and then advances to the next session. This is a high-speed
mode in which there is no time wasted waiting.
See "Parameter Set" in this document for information about how Parameter Sets are
actually allocated.
In order to ensure maximum speed for bulk dumping of a Parameter Set, the data format
used is different from that used for Individual Parameter Change. Data is transferred as-
is, using the CTK-671 memory image.
One Parameter Set can be transferred per session.
A large Parameter Set can be divided into multiple packets for transfer. In this case,
<index> field packet numbers are used.
When transferring multiple groups of small Parameter Sets, each Parameter Set must be
allocated to its own packet. Multiple Parameter Sets cannot be included within the same
packet.
2.3.2 One-way Mode Communication Flow
A session starts with the receiving device sending a request using a BDR, or with the
sending device sending BDS data. The session ends after transfer of all of the data in
the Parameter Set being transferred by the sending device is complete.
When the CTK-671 receives a BDR, it sends back the applicable Set as a BDS. When
the CTK-671 receives a BDS, it changes the corresponding Parameter Set value.
Data is divided into multiple packets of 256 bytes or less each, and transfers them at
fixed intervals (20 msec).
A final EOD informs the receiving device that the session is ended.

:EOD Data Transfer
2.3.3 Handshake Mode Communication Flow
A session starts with the receiving device sending a request using an HDR, or with the
sending device sending HDS data.
The sending device does not send the next packet until it receives an ACK from the
receiving device. The maximum wait time is at least 100 msec. Failure of a response to
arrive within the wait time (at least 100 msec) is treated as a timeout error, and data
communication is terminated.
The sending device resends the last data if the receiving device returns an HDE (error)
due to checksum mismatch, incompatible data structure, or some other reason. If an
error repeats a number of times (undefined), either the sending device or the receiving
device sends an HDJ to terminate the session.
A session ends after the sending device sends all the Parameter Sets, and sends a final
EOD in response to an HAD (ACK) from the sending device.

3. Parameter List
This list shows the parameters that can be transferred individually using System Exclusive
Messages.
• Note 1
Any parameter that has "r" to the right of its Parameter ID number is a read-only
parameter that can be used for obtaining status information only.A parameter with "w"
next to its Parameter ID is a write-only parameter, which is used for commands, etc.
• Note 2
All values in the Parameter List are hexadecimal, unless specifically noted otherwise.
• Note 3
Receipt of a value outside a specified range causes the value marked "Default" to
be used instead.

This is a request to look up and cancel the tone status of parts whose bits are set. It does
this by canceling the DSP Line selection of the parts whose corresponding bit is 1.
If the selected tone is an Advanced Tone, receipt of a DSP Line Cancel changes the
tone to its corresponding Normal Tone and then turns off the DSP Line.
When a NormalTone or User Tone is selected, the tone is not changed, but if the DSP
Line is on the DSP side, it is changed to Thru.

DSP Type Independent Parameters
The eight parameters listed below are DSP User Parameters that can be set from the
control panel, while the next 16 parameters are Internal Parameters that cannot be
edited on the control panel. The range of these parameter values is 0 to 127, regardless
of the DSPalgorithm. However, the parameters that are available depend on the DSP
algorithm, which means that not all User Parameters and Internal Parameters are
necessarily available as a particular DSP's parameters.
See the "DSP Parameter List" for details about parameters and their contents.

• About the Part Mode
Each of the CTK-671' parts has a parameter called "Part Mode," which can be set to
either Melody mode or Rhythm mode. Melody tones must be set to the Melody mode,
while drum maps used for rhythm tones must be set to the Rhythm mode.
The Part Mode parameter can be changed using a System Exclusive message (see the
section of this document titled "CTK-671 System Exclusive Format"). The Part Mode
parameter can also be changed by receipt of a Program Change message in accordance
with the Bank number specified by a Bank Select message.
Operation at this time depends on the receiving MIDI channel, as indicated below.
Operation when Bank Select/Program change is received over channel other than
Channel 10
If the Bank Select MSB is 78H, 7EH, or 7FH, receipt of Program Change switches to
the Rhythm mode.
For any other Bank Select MSB, receipt of the Program Change message changes to
the Melody mode.
Operation when Bank Select/Program change is received over Channel 10
If the Bank Select MSB is 78H, 7EH, or 7FH, receipt of Program Change message
switches to the Rhythm mode.
If the Bank Select MSB is 41H, 42H, 43H, 44H, 45H, 46H, or 79H, receipt of Program
Change changes to the Melody mode.
For any other Bank Select MSB, receipt of the Program Change message does not
change the Play Mode.
