I missed that the 6->2 mixer was a 2hp model already
I think my advice about disting still stands - you are correct about it saving the last setting, using the favourites feature greatly improves the usability too - but it's better I think to use the disting to guide you on what modules you should buy, very very occaisionally that might be an actual disting!! - but always keep at least 1 in the rack for emergencies
I think it would be very very frustrating playing back midi files from a disting - no interaction - turing machine might work though!
EDIT - I actually just looked at the info for the PolendPreset and it would appear that it may be usable as a CV sequencer too - which would cover you for that - but it looks really complicated to me! good luck with that!
I'd also consider mixing outside the box as slumberjack suggests, it would free up quite a lot of rack space, or you could just add an extra case when you need it, I really like the performance mixer and I want one (maybe this year), but it is a bit big for this size case

Utility modules are the dull polish that makes the shiny modules actually shine!!!
