I also just went with the SD-CS-MAN bag, it's reasonably priced. I then place it in a large Pelican with other gear for transport, it's fine if you aren't putting super heavy bricks in there with it and tossing the case around.

This bag is just a soft bag with thin padding. If you have rough conditions, you'll want something firmer like a Pelican. There's also an inner pocket/divider that I find useless - I cut it off.

I have the same bag for my mixer 10ii. It's too bad you cut out the divider, it works great for holding the power supply. Currently I'm using a small Orca bag, but I wouldn't want to put that bag in another one.

I use a soft briefcase for mine that was designed to carry a laptop so it has a little padding. Patagonia made briefcases for a short period (I almost wrote "a brief period") and the MixPre 10 fits nicely inside along with quite a bit of gear.

When I bought a Rode NT2 large diaphragm mic in the mid-90’s they came in a foam lined aluminium flight case, as pictured below. I’m going to get a block of correctly sized foam and cut it to suit the MixPre plus mains power supply and battery. Similar flight cases are now available for low cost, and will protect it as effectively as a Pelican…at least for my modest local travel purposes !

For those MixPre users who subsequently import into Reaper, there's a quick script within ReaClassical for handling the polywavs...see video in link below. It gives you a track naming table window, as well as the option to create a stereo wav out of the first two (main pair) iso mono files.

If ReaClassical isn't your regular DAW, it's probably best to engage with it as a portable install, to keep it separate from regular Reaper...I'll add install video guide links below for Windows/Mac/Linux portable installs (eg on a usb thumb drive), as well as the ReaClassical manual, which gives you the processes as text. Hope you find it helpful

'19.2 Multi-Channel Audio Import

If you use a portable recorder such as a MixPre, you might have a multi-channel com-
bined file. ReaClassical includes a special function for converting these into a stereo
pair + mono track set. Import your multi-channel media using a single regular track
(for a horizontal workflow) or multiple regular tracks (for a vertical workflow). Then,
simply press F10 (no need to select the items). Answer yes to the prompt that appears
if the first two channels should be treated as stereo interleaved (i.e. they represent
your main pair).

Depending on the choice made, the number of tracks in the resulting
folder(s) will adjust accordingly. If the user selects ‘no’ to keep all tracks mono, the
folder track is left empty so that the Prepare Takes T function is able to create a
muted guide track (more on this later!). Then you are given the opportunity to name
your tracks.

Obviously if you decide to move to a vertical workflow after exploding
using a single track, you can always use F8 to create your source folders then drag
the media to where you want them. If you need to bring in new takes after editing has
started, simply use the function on an empty project tab then copy or cut them into the
original project tab into the desired folder on the timeline'
