and so on.
If the I/O Identifier is not visible, this means
either
that the program has no inputs or
outputs (unlikely, except for a small number of information-only presets) or that the
program file does not contain I/O Identifier information - this will usually only apply to
presets obtained from a DSP4000 or other earlier system.
Be mindful of the "I/O Identifiers" when you select your programs and routing
configurations. You won’t want to make connections to dead inputs or outputs
unless you
plan not to use those dead inputs or outputs ! You may find yourself frequently ignoring dead
inputs or outputs, especially if you load quad or octal routing configurations but only
process stereo signals. As long as you don’t fool yourself into thinking the dead inputs or
outputs are passing audio, everything is OK! Let’s look at a few examples of routing
configurations that
rely on connections to dead inputs and outputs and, because of that
reliance, fail to do any business.
For example, the setup shown to the right is bad news. The
inputs to DSP A will never be heard because the program
"
VocalVerb 2
" doesn’t use DSP inputs 3 and 4!
Remember, the first digit in its "I/O Identifier," "
2,
"
means that only inputs 1 and 2 are live. Inputs 3 through 8
are dead
(they’re shown as dotted circles in the diagram).
You won’t hurt the H8000FW by hooking things up this
way, but you won’t pass audio!
To the right, we have another bad scene. The program "
Big Voice
" has an "I/O
Identifier" of "
22.
" That means that only DSP outputs 1
and 2 are live. Outputs 3 through 8 are dead, but in the
block diagram to the right, it is these dead outputs that are
being used. Again, you won’t hurt the H8000FW by
hooking things up this way, but you won’t pass audio!
Of course, making a connection to a dead input or output is
not necessarily a bad thing. You can make "dead
connections" as long as you don’t fool yourself into
thinking that they’re actually passing signals. For
example, you might want to filter a simple stereo
signal. You’ll use digital inputs 1 and 2 and digital
outputs 1 and 2. You don’t care what’s happening
on the rest of the digital inputs and outputs. You
load the program "
Stereo Filter
" with an "I/O
