14. MIDI INTERFACE
14.1. Channel/Controller/Value setup
Gain adjustment is done via standard MIDI control commands:
The preamp (1, 2 or 3) is selected by the MIDI channel
The optocoupler (1 to 8) is selected by the controller number
The gain value is set by adjusting the controller's value
The raw MIDI bytes are indicated in [square brackets]
DIP Address
setting
MIDI Channel * Controller number * Gain value
OFF OFF 2 = Preamp 1 [0xB1]
3 = Preamp 2 [0xB2]
4 = Preamp 3 [0xB3]
24 = Optocoupler 1 [0x18]
25 = Optocoupler 2 [0x19]
26 = Optocoupler 3 [0x1A]
27 = Optocoupler 4 [0x1B]
28 = Optocoupler 5 [0x1C]
29 = Optocoupler 6 [0x1D]
30 = Optocoupler 7 [0x1E]
31 = Optocoupler 8 [0x1F]
0...127 [0x00...0x7F]
0 = minimum gain
127 = maximum gain
Resulting gain in dB depends
on preamp type, for ADA8000
0...127 means +10..+50dB
(approx 0.3dB steps)
OFF ON 5 = Preamp 1 [0xB4]
6 = Preamp 2 [0xB5]
7 = Preamp 3 [0xB6]
ON OFF 8 = Preamp 1 [0xB7]
9 = Preamp 2 [0xB8]
10 = Preamp 3 [0xB9]
ON ON 11 = Preamp 1 [0xBA]
12 = Preamp 2 [0xBB]
13 = Preamp 3 [0xBC]
* These values and mappings can further be changed using SYSEX commands (see Advanced Topics).
Examples
(The following examples assume that the “ADDR.” DIP switches are both “OFF”):
To set the gain on preamp 1, channel 1, to 63 (mid-scale):
On MIDI channel 2, set controller number 24 to value 63
[Raw byte sequence: 0xB1 0x18 0x3F]
To set the gain on preamp 3, channel 8, to 0 (minimum):
On MIDI channel 4, set controller number 31 to value 0
[Raw byte sequence: 0xB3 0x1F 0x00]
