Salut.
I’d choose an MKII UW for samples, and +Drive for more than 128 patterns.
With UW you can sample and resample incoming sound and mangle it on the fly.
Triggering MD is easy, but beware sounds are triggered out of phase. If you use MD sequencer and external midi some phase opposition phase may occur.
Confirmed: Machinedrum MIDI in phase problem
Control parameters is not easy, Control Change numbers depending on track numbers.

I’m not the best ambassador, I traded my MD UW MKII +DRIVE with an AR MKI.
DT + DN doesn’t seem a bad combo.
