Biquad internal channel loop-through (0x28)

Each internal processing channel can receive two possible inputs at the input to the biquad

block. The input can come either from the output of that channel’s MIX#1 engine or from the

output of the bass/treble (biquad #10) of the previous channel. In this scenario, channel 1

receives channel 8. This enables the use of more than 10 biquads on any given channel at

the loss of the number of separate internal processing channels.
