Registered Parameter Number (RPN)
Changes parameter values for each tone generator part.
Normally three types of control change data are sent: RPN
MSB (101), RPN LSB (100), and Data Entry MSB (6). In the
MOTIF XF, Data Entry LSB (38) is added to this and the
resulting group of control change events is handled as one.
Once an RPN is specified, the following data entry
message received on the same channel is processed as
the value of that RPN. Prevent operational errors by
transmitting a Null message (7FH, 7FH) after using these
messages to perform a control operation. The MOTIF XF
tone generator block allows control of the 4 following
parameters:
RPN Parameter List
Non-Registered Parameter Number (NRPN)
Changes parameter values for each tone generator Part.
There is no compatibility between different manufacturers.
Numerous parameters specific to each tone generator can
be controlled to produce tonal changes. Normally three
types of control change data are sent: NRPN MSB (99),
NRPN LSB (98), and Data Entry MSB (6). In the MOTIF XF,
this group of control change events is handled as one.
Once an NRPN is specified, the following data entry
message received on the same channel is processed as
the value of that NRPN. Prevent operational errors by
transmitting an RPN Null message (7FH, 7FH) after using
these messages to perform a control operation. For filter
cutoff frequency, resonance, and other independent
control change parameters, it is normal to use the
independent control change parameters rather than the
NRPN.
n This MIDI event cannot be handled by the tone generator
block, although it can be recorded to a Song/Pattern track.
System Exclusive
Changes internal tone generator settings such as Voice
and effect settings, remote switch control, tone generator
mode switching, and others via MIDI. The 2nd byte is a
manufacturer ID number, and there is no data compatibility
between manufacturers. This type of event is used to
control MOTIF XF-specific functions. The cursor can be
used to scroll through the data if the data size is greater
than 17 bytes.

000 000 Pitch Bend Sensitivity 000 – 024 — 024 Specifies the amount of pitch bend produced in response to pitch
bend data in semitone increments.

000 002 Coarse Tune -24 – +24 — +00 Adjusts the tuning in semitone increments.
127 127 Null — — — Voids the RPN and NRPN settings so no tone generator settings are
changed when subsequent Data Entry messages are received.
