Will denon make backpacks specifically for the mc7000??
Nope, however… Namba Gear ( http://nambagear.com/products/juju-v2-magic-bag-effectsdj-bag/ ) make the JuJu case, which can be slung over the back - in fact, you could win one if you get lively and check out our Denon DJ Facebook page
Other manufacturers options are available too if you search the web
UDG have a number of options: https://www.udggear.com/by-device/denon/mc7000
Odyssey ‘Red’ makes a great bag/case for this, however it’s more of a shoulder bag than a backpack.
I use MAGMA DIGI CONTROL BACKPACK XXL . Fits perfect
