Alesis QuadraVerb MIDI OPCODES

QUADRAVERB PLUS MIDI IMPLEMENTATION

SYSTEM EXCLUSIVE FORMAT

The QuadraVerb MIDI System Exclusive message format is as follows:

F0 System exclusive status 00 00 0E Alesis manufacturer id# 02 Quadraverb id# cc Opcode dd Data : : : : F7 End-Of-Exclusive

OPCODES:

01 - MIDI Editting

F0 00 00 0E 02 01<function#><page#>< value1>< value2>< value3>F7

<function#> = 1=reverb, 2=delay, 3=pitch, 4=eq, 7=config, 8=mix, 9=mod,

10=name

<page#> = 0..n where n is the maximum page # for the selected function

<value1-3> = new parameter value in the following format:

Data: B7 B6 B5 B4 B3 B2 B1 B0 (MSB) A7 A6 A5 A4 A3 A2 A1 A0 (LSB)

Sent: 0 A7 A6 A5 A4 A3 A2 A1 <value1> 0 A0 B7 B6 B5 B4 B3 B2 <value2> 0 B1 B0 0 0 0 0 0 <value3>

All parameters to be edited must be sent in this format (12 MIDI bytes), regardless of the number of bits required to transmit the value of the parameter. When the QuadraVerb receives this message, it will edit the specified parameter to the new value and display it. If the function and page selected does not exist in the current configuration, the command will be ignored. If the value received is out of range for the

parameter selected, the range will be limited to a legal value. The function and page numbers for each parameter are shown in the next section.

02 - MIDI Data Dump F0 00 00 0E 02 02 <program#> <data> F7

<program#> = 0..99 selects individual programs = 100 selects the edit buffer = > 100 selects all 100 programs

<data> is in a packed format in order to optimize data transfer. Eight MIDI bytes are used to transmit each block of 7 QuadraVerb data bytes. If the 7 data bytes are looked at as one 56-bit word, the format for transmission is eight 7-bit words beginning with the most significant bit of the first byte, as follows:

SEVEN QUADRAVERB BYTES: 0: A7 A6 A5 A4 A3 A2 A1 A0 1: B7 B6 B5 B4 B3 B2 B1 B0 2: C7 C6 C5 C4 C3 C2 C1 C0 3: D7 D6 D5 D4 D3 D2 D1 D0 4: E7 E6 E5 E4 E3 E2 E1 E0 5: F7 F6 F5 F4 F3 F2 F1 F0 6: G7 G6 G5 G4 G3 G2 G1 G0

TRANSMITTED AS: 0: 0 A7 A6 A5 A4 A3 A2 A1 1: 0 A0 B7 B6 B5 B4 B3 B2 2: 0 B1 B0 C7 C6 C5 C4 C3 3: 0 C2 C1 C0 D7 D6 D5 D4 4: 0 D3 D2 D1 D0 E7 E6 E5 5: 0 E4 E3 E2 E1 E0 F7 F6 6: 0 F5 F4 F3 F2 F1 F0 G7 7: 0 G6 G5 G4 G3 G2 G1 G0

There are 147 bytes sent for a single data dump, which corresponds to 128 bytes of program data. There are 14,629 bytes sent for a 100 program dump, which corresponds to 12,800 bytes of program data. The location of each parameter within a program is shown in the next section.

When the QuadraVerb receives a data dump message, the display reads:

MIDI DATA ...

Should the Quadraverb's MIDI input buffer overflow, the display will read:

MIDI INPUT BUFFER OVERFLOW

This message will remain on the display until any button is pressed.

03 - MIDI Dump Request

F0 00 00 0E 02 03 <program#> F7

<program#> = 0..99 selects individual programs = 100 selects the edit buffer = > 100 selects all 100 programs

When this message is received, a MIDI data dump will be initiated, and the display will read:

MIDI DATA DUMP IN PROGRESS

Upon completion of the dump, the display will return to its previously displayed page.

INDIVIDUAL PARAMETER LOCATION FUNCTION AND PAGE VALUES

The following lists give the parameter locations and ranges for each of the effects in each of the configurations. The parameter associated with a particular function and page may be dependent on both the current configuration, and the current mode of the effect (e.g., chorus, phase, etc.). In conditions where a page relates to different parameters depending on the mode of the effect, the parameters are listed in tables under each mode. All parameters are offset binary values. This means that a signed parameter with a range of

-99 to +99 in the display is actually stored as 0 for -99, 99 for 0, and 198 for +99.
