Thanks for answers.
Is the only way to get control of the mic gain from the physical pots by operating in Custom Mode? Can't see how to do it in Advanced mode. I like to be able to adjust the input level easily and don't really like doing this in menus on the tiny but nonetheless very good touch screen.

Yes, You can use channel knobs to adjust your ISO levels. To do this, you would select Custom mode and set Record to Advanced and leave Channel set to Basic. When Channel is set to Basic, ISO levels are post channel knob and when Record is set to Advanced, ISOs can be armed. This has been covered in these threads many times. You can set it and it will hold the setting, or if you use the deck in multiple applications and have a poor memory, you can set up a pre-set.
When I just record a pair of linked (1&2) ISOs and don't record anything else under the record options then I get a stereo file that imports into Logic Pro fine as an interleaved file - in other words it sets up a stereo channel on one track.
If I opt to record the L,R to the card then when you import into Logic it comes in as separate audio files onto sep tracks which you can then pan hard L&R etc. bit of a pain.
I'm running latest release of the firmware and Logic pro X
I am not understanding at all what you are explaining. When you say "interleaved", are you talking about a polyfile? That is how these decks save your files, but it is easy to break them down to the recorded tracks in any way you desire, stereo, mono , single tracks , dual tracks, mix tack etc. I use soundforge and the polyfiles are great, because I can track everything and then break them down to the files I want.
Apple describe interleaved as this: "You can store multi-channel audio as interleaved or split channel audio files. An interleaved audio file contains all channel information, stored in an alternating single “stream.”For stereo files, this would be left channel, right channel, left, right, and so on."
When bringing files from the MixPre into Logic, if you have only recorded a linked pair of ISOs then that comes into Logic as I would expect as a single stream stereo track - as opposed to split mono tracks which you could then pair and pan L&R as desired. If you record say 2 ISOs and a Linked L&R when you bring that into Logic everything comes in as split channel separate files. It's no big deal, I was just wondering if it was a quirk of Logic.
