Hi there!
I'm totally new to the multieffects rack world, and recently got a hold of one. I've read the user manual + previous topics and from that went with SPDIF routing. I tried the following:
Device routing = HD Pro X, both SPDIF ports -> Scarlett 8i6, both SPDIF ports -> Scarlett connected to PC. Studio monitors connected to monitor inputs of Scarlett.
Guitar routing = Guitar -> cable -> Input 1 of Scarlett (front side of audio interface).
Open focusrite control program = SPDIF synced at sample rate 44,100 Hz (does not sync at other values) Clock source = SPDIF. Input settings = Line (not Instrument)
HD Pro X in USB mode at the same time, to use HD Pro X Edit.
Result = Focusrite shows signal when strumming on the guitar. All volume knobs up. Neither signal nor sound coming from HD Pro X, Pro X Edit or even DAW (Nuendo 11).
DAW setup = Focusrite ASIO USB selected. When creating an audio track, I tried all the SPDIF inputs on the list. Still no signal/sound.
I'm obviously not doing it correctly, and would very much appreciate help.
