i know all of that, let me elaborate on the issue a bit more
got a Steinberg MR816x which works fine
i can connect a mic to input 1 and record vocals in mono, stereo no problem, with direct monitoring enabled and the MR reverb for the performer on the Studio1 mix.
Now… I’ve also got a SSL Alpha channel, this unit has analogue and spdif out, analogue again no issue, plug in in the MR 1/2 insert (to bypass the MR per-amp) and record away, all configs work.
however, the MR also has an spdif input.
since spdif is always 2 channel the SSL sends out the processed signal on spdif L and an unprocessed signal on spdif R
Now, if things were easy, one would map MR spdif L to a mono input and just do the same stuff as with an anlogue input right? WRONG! if you don;t map the right channel the spdif will not lock
Ok, you think then create 2 mono inputs (1 for spdif L and one for R) WRONG! 2 mono’s won’t lock either.
ok, you think so the the input needs to be stereo, sort of makes sense. I’ll sort it out on the channel side.
so you create a mono channel and map stereo L in to that channel, guess what? direct monitoring will not work
ok let’s map to stereo in R, same issue
ok let’s make a stereo channel then, so stereo IN stereo OUT et voilla! direct monitoring works, however, every recording is left channel processed sound, right channel unprocessed sound.
mixdown works to split these, but i.e. routing the stereo WAV to a mono subgroup just creates a summed mix even with the panning all to the left. So it’s not as easy as its sounds, Steinberg just needs to test this and fix whatever is broken with a spdif discrete L or R CH support.
