format. For example, 'F04GAINI*ÄÄÄÄÄÄÄÄääää ' sets the input gain of channels 1-8 to 10 dB and the input
gain of channels A-D to 0 dB. (10 + 132 = 142 = 0x8E (hex) = Ä (ASCII), 0 + 132 = 132 = 0x84 (hex) = ä
(ASCII))
As an interesting example, consider sending 'F04GAINI*>3 ' after the above example. This will result in all the
input gains being incremented by 3 dB so that channels 1-8 are at 13 dB and channels A-D are at 3 dB. The
Vortex will respond with a status message of 'F04GAINI*ææææææææçççç '. (13 + 132 = 145 = 0x91 (hex) = æ
(ASCII), 3 + 132 = 135 = 0x87 (hex) = ç (ASCII))
Queries using the '?' character are straightforward. For example, 'F04GAINI1? ' might return 'F04GAINI110 ',
while 'F04GAINI*? ' might return 'F04GAINI*ÄÄÄÄÄÄÄÄääää '.
6.4. Matrix Commands
Matrix commands are used for controlling parameters that exist at the crosspoints of the mixing matrices. Typical
parameters include gating (for automixed signals), gain and mute. Before describing the matrix commands, it is
necessary to give a description of the matrices involved. During the following discussion, it will be helpful to refer
to the figure below, which shows all the matrices with their input and output labels.
