DisCover 5 MIDI Implementation

DisCover 5 MIDI Implementation
The DisCover 5 implements additional functionality and parameters over and above
previous Roland Instruments, which itself was an expansion of the GS sound generator
format. These functions and parameters are marked by a [DisCover 5] symbol. If MIDI
messages marked by a [DisCover 5] symbol are transmitted to another GS-format
sound generator, those messages may not be recognized.
The Vocal Harmonizer parameters cannot be controlled via MIDI.
1. Receive data
Channel Voice Messages
Note off
For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each
Instrument.
The velocity values of Note Off messages are ignored.
Note on
Not received when Rx.NOTE MESSAGE = OFF. (Initial value is ON)
For Drum Parts, these messages are not received when Rx.NOTE ON = OFF for
each Instrument.
Polyphonic Key Pressure
Not received when Rx.POLY PRESSURE (PAf) = OFF. (Initial value is ON)
The resulting effect is determined by System Exclusive messages. With the initial
settings, there will be no effect.
Control Change
When Rx.CONTROL CHANGE = OFF, all control change messages except for
Channel Mode messages will be ignored.
The value specified by a Control Change message will not be reset even by a Pro-
gram Change, etc.
Bank Select (Controller number 0, 32)
Not received when Rx.BANK SELECT = OFF.
“Rx.BANK SELECT” is set to OFF by “GM1 System On,” and Bank Select messages
will be ignored.
Rx.BANK SELECT is set to ON by “GM2 System On.
Rx.BANK SELECT is set to ON by power-on reset or by receiving “GS Reset.”
When Rx.BANK SELECT LSB = OFF, Bank number LSB (llH) will be handled as 00H
regardless of the received value. However, when sending Bank Select messages,
you have to send both the MSB (mmH) and LSB (llH, the value should be 00H) to-
gether.
Bank Select processing will be suspended until a Program Change message is re-
ceived.
The GS format “Variation number” is the value of the Bank Select MSB (Controller
number 0) expressed in decimal.
Some other GS devices do not recognize the Bank Select LSB (CC32).
Modulation (Controller number 1)
Not received when Rx.MODULATION = OFF (Initial value is ON)
The resulting effect is determined by System Exclusive messages. With the initial
settings, this is Pitch Modulation Depth.
Portamento Time (Controller number 5)
This adjusts the rate of pitch change when Portamento is ON or when using the Por-
tamento Control. A value of 0 results in the fastest change.
Data Entry (Controller number 6, 38)
Volume (Controller number 7)
Volume messages are used to adjust the volume balance of each Part.
Not received when Rx.VOLUME = OFF. (Initial value is ON)
Pan (Controller number 10)
The stereo position can be adjusted over 127 steps.
For Rhythm Parts, this is a relative adjustment of each Instrument’s pan setting.
Not received when Rx.PANPOT = OFF. (Initial value is ON)
Expression (Controller number 11)
This adjusts the volume of a Part. It can be used independently from Volume mes-
sages. Expression messages are used for musical expression within a performance;
e.g., expression pedal movements, crescendo and decrescendo.
Not received when Rx.EXPRESSION = OFF. (Initial value is ON)
Hold 1 (Controller number 64)
Not received when Rx.HOLD1 = OFF. (Initial value is ON)
Portamento (Controller number 65)
Not received when Rx.PORTAMENTO = OFF. (Initial value is ON)
Sostenuto (Controller number 66)
Not received when Rx.SOSTENUTO = OFF. (Initial value is ON)
Soft (Controller number 67)
Not received when Rx.SOFT = OFF. (Initial value is ON)
Filter Resonance (Timbre/Harmonic Intensity) (Controller number 71) [DisCover 5]

NRPN MSB/LSB (Controller number 99, 98)
n = MIDI channel number: 0H~FH (Ch.1~16)
mm = upper byte (MSB) of the parameter number specified by NRPN
ll = lower byte (LSB) of the parameter number specified by NRPN
Rx.NRPN is set to OFF by power-on reset or by receiving “GM1 System On” or “GM2
System On,” and NRPN message will be ignored. NRPN message will be received
when Rx.NRPN= ON, or by receiving “GS RESET.”
The value set by NRPN will not be reset even if Program Change or Reset All Con-
trollers is received.
**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended range
of control changes to be used. On the DisCover 5, NRPN messages can be used to
modify sound parameters, etc.
To use these messages, you must first use NRPN messages (Controller number 98
and 99, their order does not matter) to specify the parameter to be controlled, 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. Refer to “5. Supplementary mate-
rial”, Examples of actual MIDI messages, [Example 4] (page 20). On the DisCover 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 DisCover 5, NRPN can be used to modify the following parameters.
Parameters marked “relative change” will change relatively to the preset value(40H).
Even among different GS devices, “relative change” parameters may sometimes dif-
fer in the way the sound changes or in the range of change.
Parameters marked “absolute changewill be set to the absolute value of the param-
eter, regardless of the preset value.
Data entry LSB (llH) is ignored.
Part On/Off NRPN are received and transmitted through the Basic MIDI Channel.
RPN MSB/LSB (Controller number 101, 100)
n = MIDI channel number: 0H~FH (Ch.1~16)
mm = upper byte (MSB) of parameter number specified by RPN
ll = lower byte (LSB) of parameter number specified by RPN
Not received when Rx.RPN = OFF.
The value specified by RPN will not be reset even by messages such as Program
Change or Reset All Controller.
**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 (Controller number 101 and 100, their
order does not matter) to specify the parameter to be controlled, and then use Data
Entry messages (Controller number 6, 38) to specify the value of the specified param-
eter. 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 rec-
ommended that you set RPN Null (RPN Number = 7FH 7FH) when you have finished
setting the value of the desired parameter. Refer to “5. Supplementary material”,
Examples of actual MIDI messages, [Example 4] (page 20).
On the DisCover 5, RPN can be used to modify the following parameters.
