Hello guys. Like many of you i feel a bit let down with the fact that there is no SPDIF output on the Quadcortex. I’m using the Apollo Duo Twin (USB 3, on windows) as an interface and am not interested in switching back and forth between the QC and the UA as my audio interface. I want to keep the set-up i currently have with my AX8 which is :
Guitar straight into the UA apollo input
Dry signal is now on my DAW and i can do whatever i want
Dry signal goes back out immediately on output 3 and goes into my ax8
AX8 goes back in the Apollo via SPDIF
That way i can switch between plug-ins and AX8 very easily, always capturing the dry signal, re-amping on the fly, no latency, no feedback it works like a charm
How could i reproduce that beautiful workflow with the QC ?
I don’t wanna send the QC mono signal back into the Apollo, i’d miss out on too many amazing delays
I’ve been looking around and there are plenty of USB to coaxial / SPDIF converters, would that do the trick ?
I see your problem as the optical input on the Twin provides 2 extra channels to the interface, while being stuck with he 2 inputs with analog. The USB audio interface of the QC is 8 channels and idk if it can be set to a plain 2 channel interface (to use with a converter as you suggest).
One solution is to aggretage the twin and the QC with asio4all to one large interface. Another would be to get a analog-to-ADAT interface for your twin and go all analog from the QC. Neither is as elegant as is would with a QC S/PDIF out…
I have had mixed like using aggregate devices in macOS, it works, but can be quirky depending on the actual devices. I use Loopback to integrate and map physical devices and apps into a virtual device. Its expensive, but works very well. I’ll try that with Quad Cortex when it ships.
When tracking guitars, I run USB from the modeler directly into the DAW (wet and dry) while monitoring the analog inputs into the interface. All playback is through the interface. No aggregate interfaces, no excess A/D conversions.
