Topic: Latency on Hardware Loopback
I am wondering if there is any latency if I use a hardware loopback (a wire) on an ADAT port.
For example: I have a route in TotalMix from:
AN 7/8 IN to AN 1/2 OUT
... that should have the latency of the ADC and the DAC - around 5+7 samples on the UCX II.
If I add an intervening route ... making it:
AN 7/8 IN to ADAT 7/8 OUT to ADAT cable to ADAT 7/8 IN to AN 1/2 OUT
... would the latency increase?
Motivation: the reason I'm looking to do this is because I need to control the level of one AN 7/8 input going to two different outputs from a MIDI Source. The MIDI sequence to select the two outputs is quite slow (around 100ms) and constantly selecting the two output channels and changing the level of the input channel for that output as the knob is turning is far too slow / laggy. With the setup I'm describing using the physical loopback cable, I could (hopefully) control both target outputs by selecting affecting just the single output fader for ADAT 7/8.
This scheme would only be useful if there is no added latency ...
