Step-by-Step Descriptions of the Routing Process Flow
The audio source from the hard drive is sent to Audio 1. Once it is received, it encounters
the I/O plug-in insert, a plug-in that routes the audio to an external audio device.
The insert outputs the audio to channels 3 and 4 of the aggregate audio device, since
channels 1 and 2 are reserved for final speaker output.
The aggregate audio device subsequently sends the output from its channels 3 and 4 to the
H8000FW’s input channels 1 and 2. As the aggregate audio device’s first two channels are
internal audio, its input channels 3 and 4 correlate to the H8000FW’s channels 1 and 2, its
channels 5 and 6 with the H8000FW’s channels 3 and 4, and so on. As defined in its
Routing Preset 20, the H8000FW’s DSP machine A processes channels 1-4; its DSP
machine B process channels 5-8.
Processing is performed to the audio on the H8000FW, and the processed audio is output
from its channels 1 and 2 to the aggregate audio devices input channels 3 and 4.
The audio is now input back to I/O plug-in on Audio 1 . The audio now proceeds to
encounter the bus we inserted.
The bus routes the audio and sends one stream to the Audio 1 output and a second stream
to the Bus 1 input.
The bus audio is subsequently sent to the aggregate audio device’s channels 7 and 8
outputs, as defined in the Logic Pro session.
From here, it is routed to the H8000FW’s input channels 5 and 6.
Processing is performed on the audio using the H8000FW’s machine B, after which it is
sent through the H8000FW’s output channels 5 and 6 back to the aggregate audio device
input channels 7 and 8.
This audio stream now is routed to Audio 2, as defined in the Logic Pro session.
Finally, outputs from Audio 1 and Audio 2 are mixed, as defined in the Logic Pro session,
and returned to the aggregate audio devices output channels 1 and 2, which are in fact the
speakers. All that’s now left to do is listen.
