*If a voice is already sounding for a note number identical to the Source Note Number, this voice will continue sounding (i.e., legato) and will, when the next Note-on is received, smoothly change to the pitch of that Note-on.
*The rate of the pitch change caused by Portamento Control is determined by the Portamento Time value.

*The value set by NRPN will not be reset even if Program Change or Reset All Controllers is received.
**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended range of control changes to be used.
To use these messages, you must first use NRPN MSB and NRPN LSB messages to specify the parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an NRPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter. Refer to Section 4. Supplementary material “Examples of actual MIDI messages” <Example 4> (page 12). On the GS devices, Data entry LSB (llH) of NRPN is ignored, so it is no problem to send Data entry MSB (mmH) only (without Data entry LSB).
On the KR375, NRPN can be used to modify the following parameters.

**RPN**
The RPN (Registered Parameter Number) messages are expanded control changes, and each function of an RPN is described by the MIDI Standard.
To use these messages, you must first use RPN MSB and RPN LSB messages to specify the parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an RPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter.Refer to Section 4. “Examples of actual MIDI messages” <Example 4> (page 12).
On the KR375, RPN can be used to modify the following parameters.

The System Exclusive Messages received by the KR375 are; messages related to mode settings, Universal Realtime System Exclusive messages and Data Set (DT1).
● System exclusive messages related to mode settings
These messages are used to initialize a device to GS or General MIDI mode, or change the operating mode. When creating performance data, a “Turn General MIDI System On” message should be inserted at the beginning of a General MIDI score, and a “GS Reset” message at the beginning of a GS music data. Each song should contain only one mode message as appropriate for the type of data. (Do not insert two or more mode setting messages in a single song.)
“Turn General MIDI System On and “Turn General MIDI System Off” use Universal Nonrealtime Message format. “GS Reset” use Roland system exclusive format “Data Set 1 (DT1).”
Turn General MIDI System On
This is a command message that resets the internal settings of the unit to the General MIDI initial state (General MIDI System-Level 1). After receiving this message KR375, will automatically be set to the proper condition for correctly playing a General MIDI score.

● Data transmission
KR375 can receive the various parameters using System Exclusive messages.
The exclusive message of GS format data has a model ID of 42H and a device ID of 10H (17), and it is common to all the GS devices.
Data set 1 DT1
This is the message that actually performs data transmission, and is used when you wish to transmit the data.

*The amount of data that can be transmitted at one time depends on the type of data, and data can be received only from the specified starting address and size. Refer to the Address and Size given in Section 3 (page 6).
*Data larger than 128 bytes must be divided into packets of 128 bytes or less. If “Data Set 1” is transmitted successively, there must be an interval of at least 40 ms between packets.
*Regarding the checksum please refer to section 4 (page 12).

■ Individual Parameters
Individual Parameter Transmission transmits data (or requests data) for one parameter as one exclusive message (one packet of “F0 ..... F7”).
In Individual Parameter Transmission, you must use the Address and Size listed in the following “Parameter Address Map.” Addresses marked at “#” cannot be used as starting addresses.
● System Parameters
Parameters related to the system of the device are called System Parameters.

*REVERB MACRO is a macro parameter that allows global setting of reverb parameters. When you select the reverb type with REVERB MACRO, each reverb parameter will be set to the most suitable value.
*REVERB CHARACTER is a parameter that changes the reverb algorithm. The value of REVERB CHARACTER corresponds to the REVERB MACRO of the same number.
