Rx.NRPN = ON, or by receiving "GS RESET".
* 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 3. Supplementary material
"Examples of actual MIDI messages" <Example 4> (p. 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 MT-90s, 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

setting the value of the desired parameter.Refer to Section 3. "Examples of actual MIDI

The System Exclusive Messages received by the MT-90s 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 "GM1 System On" message should be
inserted at the beginning of a General MIDI 1 score, a "GM2 System On" message at the
beginning of a General MIDI 2 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.)
"GM System On" uses Universal Non-realtime Message format. "GS Reset" uses Roland
system Exclusive format "Data Set 1 (DT1)."
GM1 System On
This is a command message that resets the internal settings of the unit to the General MIDI 1
initial state. After receiving this message, the MT-90s will automatically be set to the proper
condition for correctly playing a General MIDI score.
