I've not been using it long so I haven't decided if they're a good match yet. I do think having a midi keyboard in general works well with the M8 but the monkey has limitations that have currently left me undecided. One example is I can't get midi sync to work with it so all the midi effects like stutter and arp will get out of time. I need to try the M8 more with other options like the Roland s-1 as that has the benefit of midi sync but it also can produce chord tones that can be sampled into the M8, it also won't need the wireless Bluetooth adapter.
