If not using the laptop compartment for an actual laptop, there’s another way to get the 4 mentioned Elektrons in if putting one MK1 in the laptop compartment, short edge down.
The other MK1 in the bigger compartment.
And both models on the sides, all with their respective short edges going down into the bag. first.
I like this mode better, and I don’t bring my laptop to gigs anyway, so this works well.
Just imagine my M:C on the left:
Tightening the straps on the side keeps the deck savers all tight too. No need for additional fastening of deck savers.
And I forgot about the rear padded pocket that touches your back. That’ll be nice for audio leads.
