•A Note-on received immediately after a Portamento Control message will
change continuously in pitch, starting from the pitch of the Source Note
Number.
•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.

❍
•This message adjusts the Reverb Send Level of each Part.
•Not received when “Reverb” RX Event is Off.
❍
•This message adjusts the Chorus Send Level of each Part.
•Not received when “Chorus” RX Event is Off.
❍
•The value set by NRPN will not be reset even if Program Change or Reset
All Controllers is received.
•Not received when “NRPN” RX Event is Off.
**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended
range of control changes to be used. On the JM-5, NRPN messages can be
used to modify sound parameters, etc.
To use these messages, you must first use NRPN messages (Controller num-
ber 98 and 99, their order does not matter) to specify the parameter to be con-
trolled, and then use Data Entry messages (Controller number 6) 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.
On the JM-5, Data entry LSB (Controller number 38) of NRPN is ignored, so it
is no problem to send Data entry MSB (Controller number 6) only (without Data
entry LSB).
On the JM-5, NRPN can be used to modify the following parameters:
