I've now turned off all the ADAT digital outs, and Main Out and Phones are set to mirror Analog Outputs 1/2.
I've also turned off all the ADAT ins.
This means the driver should now only have:
In 1/2 = Mic/Instrument In 1/2
In 3/4 = Analog TRS In 1/2
In 5/6 = Analog TRS In 3/4
In 7/8 = Analog TRS In 5/6
In 9/10 = Analog TRS In 7/8
In 11/12 = Reverb Returns
In 13/14 = Return Assign (for bouncing mixes via the 828mk3)
In 15/16 = SPDIF In L/R
Out 1/2 = Analog Outs 1/2 + Main Outs + Phones 1/2
Out 3/4 = Analog Outs 3/4
Out 5/6 = Analog Outs 5/6
Out 7/8 = Analog Outs 7/8
Out 9/10 = SPDIF Outs L/R
I still seem to have 14 outs though! The MOTU manual says SPDIF should normally be 14, but if Mains and Phones are set to mirror they disappear and the list should shrink by two for each. Huh? I should only have 10 outs now! FFS.
On I brighter note I should be getting my APC tomorrow!
