VIRUS MIDI SYSTEM EXCLUSIVE IMPLEMENTATION  


The Parameters of the VIRUS are organized in three so-called pages A, B and C.

Each page contents 128 parameters, addressed by numbers from 0 to 127.

Each parameter is repesented by one byte with a maximum value of 127.

All parameters are individually accessible by SysEx-Parameterchange.

The pages A and B represent a Single-Program, so a Single-Program contents 256 Bytes.

Page A (LowPage) contents Single parameters that are usefull for MIDI automation. The parameters
of this page are additionally controllable by MIDI Control Change. The sending and reception 
of MIDI Control Change can be enabled or disabled by MIDI CONTROL LowPage (CTRL menu). 
When disabled (LowPage=SysEx), the VIRUS only sends and receives SysEx Parameter Change on Page A.
When enabled (LowPage=Contr), the VIRUS sends MIDI Control Change on parameter movement, 
and receives both MIDI Control Change and SysEx-Parameterchange on Page A.
The default setting is LowPage=Contr.

The remaining Single parameters in Page B (HiPage) are additionally controllable by 
MIDI Polyphonic Pressure (!). The sending and reception of MIDI Poly Pressure can be enabled 
or disabled by MIDI CONTROL HiPage (CTRL menu). 
When disabled (LowPage=SysEx), the VIRUS only sends and receives SysEx Parameter Change on Page B.
When enabled (LowPage=PolyPrs), the VIRUS sends MIDI Poly Pressure on parameter movement, 
and receives both MIDI Poly Pressure and SysEx Parameter Change on Page B.
This feature should not be used in connection with a keyboard that sends Polyphonic Pressure.
The default setting is LowPage=SysEx.

Page C contents Multi parameters and Global parameters. These parameters are sent and received 
only by SysEx Parameter Change.


In the following, all bytes are shown in hexadecimal representation.


Control Change message (only Page A)

Bc	:Status byte, c=MIDI channel
nn	:Parameter Number 		0..127	(see parameter list Page A)
vv	:Parameter Value  		0..127	(see parameter list Page A)

Note:
The Control Change messages are defined as Performance Controller (e.g. Modulation Wheel or 
Hold Pedal) or Sound Parameters (e.g. Cutoff or Patch Volume).
The Performance Controllers are not stored with a Single-Sound. If more than one Multi Part is
set to the same MIDI channel, all Parts on this MIDI channel receive the same Performance
Controllers.
The Sound Parameters are stored with a Single Sound. If more than one Multi Part is set to the
same MIDI channel, the Sound Parameter is receiced only by the Multi Part with the lowest part 
number.

Example: B0,21,40
Set oscillator balance (21 hex = 33 dec) on MIDI channel 1 to the middle position (40 hex =64 dec).



Polyphonic Pressure message (only Page B)

Ac	:Status byte, c=MIDI channel
nn	:Parameter Number		0..127	(see parameter list Page B)
vv	:Parameter Value  		0..127	(see parameter list Page B)

Example: A2,07,25
Control LFO3 Rate on MIDI channel 3 (!).

SysEx Parameterchange:

[message]=
7x	:Parameterchange 		70:page A; 71:page B; 72:page C
pp	:Part number			00..0F: Multi part 1..16; 40: Single 
nn	:Parameter Number		0..127	(see parameter list)
vv	:Parameter Value		0..127	(see parameter list)

{F0,00,20,33,01,dd,7x,pp,nn,vv,F7}

Note:
The SysEx Parameterchange affects one of the sixteen single edit buffer in Multi Mode addressed 
by the part number (00..0F) or the Single buffer in Single Mode (part number 40).
If a global parameter or a Multi parameter is accessed, which is not part-sensitive 
(e.g. Input Boost or Multi Delay Time), the part number is ignored.

Example: F0,00,20,33,01,10,70,05,28,5F,F7
Set Cutoff on Part 6 to decimal value 95.
(10: device ID omni; 70: page A, 05: part 6; 28: parameter Cutoff, 5F: decimal value 95)



Single Dump

[message]=
10	:Single Dump
bb	:Bank Number 			00: Single Edit buffer; 01..04: Single Bank A..D
ss	:Program Number			0..127
[256 single bytes]
cs	;Checksum			optional

{F0,00,20,33,01,dd,10,bb,ss,[256 single bytes],cs,F7}

Note:
When bank number is set to 00, the program number is the part number that addresses one of the 
sixteen Single Edit buffer in Multi Mode (00..0F) or the Single buffer in Single Mode (40).

[256 single bytes] contents the Single parameter pages A and B, each 128 bytes long.

Checksum is the sum 
(DeviceID + 10 + BankNumber + ProgramNumber + [256 single bytes]) AND 7F.
A dump with a wrong checksum will be received, but an error message will appear on the display.



Multi Dump

[message]=
11	:Multi Dump
bb	:Bank Number 			00:Multi Edit buffer; 01:multi bank
mm	:Program Number			0..127
[256 multi bytes]
cs	;Checksum			optional

{F0,00,20,33,01,dd,11,bb,mm,[256 multi bytes],cs,F7}

Note:
When bank number 00, the dump destination is the Multi Edit buffer. In this case the program
number is ignored.

[256 multi bytes] contents the Multi parameters in a special succession. See Multi Dump Table.

Checksum is the sum 
(DeviceID + 11 + BankNumber + ProgramNumber + [256 multi bytes]) AND 7F.
A dump with a wrong checksum will be received, but an error message will appear on the display.



Single Request

[message]=
30	:Single Request

ss	:Program Number			0..127

Note:
When bank number is set to 00, the program number is the part number that addresses one of the 
sixteen Single Edit buffer in Multi Mode (00..0F) or the Single buffer in Single Mode (40).



Multi Request

[message]=
31	:Multi Request
bb	:Bank Number 			00:Multi Edit buffer; 01:multi bank
mm	:Program Number			0..127

{F0,00,20,33,01,dd,31,bb,mm,F7}

Note:
When bank number 00, the dump destination is the Multi Edit buffer. In this case the program
number is ignored.

Classes:

p: Performance Controller
Accessible by Control message.
Performance Controllers are not stored with a Single-Sound.
If more than one Multi Part is set to the same MIDI channel, all Parts on this MIDI channel 
receive the same Performance Controllers.


a: Sound Parameter of Bank A
Accessible by Control message, SysEx-Parameterchange and Single-Dump.
The Sound Parameters are stored with a Single Sound. 
When received as Control Message, the Sound Parameter is received only by the Multi Part with 
the lowest part number, if more than one Multi Part is set to the same MIDI channel.
When received as SysEx-Parameterchange or Single-Dump, the part is addressed by the part number
irrespective of the actual MIDI channel setting.


b: Sound Parameter of Bank B
Accessible by MIDI Polyphonic Pressure, SysEx-Parameterchange and Single-Dump.
The Sound Parameters are stored with a Single Sound. 
When received as Polyphonic Pressure, the Sound Parameter is received only by the Multi Part 
with the lowest part number, if more than one Multi Part is set to the same MIDI channel.
When received as SysEx-Parameterchange or Single-Dump, the part is addressed by the part number
irrespective of the actual MIDI channel setting.


m: Multi Parameter
Accessible by SysEx-Parameterchange and Multi-Dump
The Multi Parameters are stored with a Multi Patch.


ms: Multi/Single Parameter
When in Single Mode, the parameter is received and stored with the Single Sound.
When in Multi Mode, the parameter is received and stored with the Multi Patch.
In Multi Mode the Single Sound settings are ignored while the corresponding Multi Patch 
settings are active.


np: Non-part-sensitive Sound Parameter
When in Multi Mode, the parameter affects all Multi Parts.


bpc: Bank/Program-Change Parameter
Bank Select selects the Single bank accessed by a subsequent Program Change, similar to
the regular Bank Select.
Bank Change directly changes the Single program to the requested bank, without changing
the program number.
Program Change directly changes the Single program to the requested program number, without
changing the bank number; similar to the regular Program Change.
Part number $40 will address the Single buffer in Single Mode.


g: Global Parameter
The Global Parameters are independend of Single Sounds or Multi Patches and non-part sensitive.




Notes:
On non-part-sensitive parameters the part number is ignored, but must still be sent as any value.

The Virus can be switched between Multi Mode and Single Mode by parameter C123 Part Number.

Remarks for editor/librarian programs
Not all 256 bytes of a Single or Multi Dump are defined as a parameter. Some of them are defined
for internal use or reserved for future applications. In a bulk dump these byte should not be
changed, they should be sent to the Virus on the same value as they were received in the dump.

One of the internal parameter (A 0) is the sound version number. On future Virus system updates 
new parameters will be defined. When the Virus receives an older sound, the new parameters will
be set to default values in the edit buffer and the version number will be updated automatically. 
The Virus update algorithm can be used from outside just by sending a dump and requesting it 
back.
