Hi venomous, i’m a longtime mpc user (used an mpc1000 as my centerpiece since 2006) who switched to the dt 2 years ago, mainly doing samplebased hiphop, so i’ll give you my take on this:
The mpc is a very playable device, you can chop samples and play them with the pads, which is a very intuitive way of working. It also has a song mode, which the dt doesnt have, so you can easily make intro’s and b parts to a song. Its a great sequencer, and sampler. The mpc can do most of the things you need, even today, but it doesn’t really excel at anything, nor does it have features that make you go ‘wow this is awesome/unexpected’. To me the mpc 1000 still feels like a reliable old allround workhorse that kept its power after allmost 15 years of service, and still makes for a great companion.
The DT lacks some very basic things (like stereo sampling, a songmode, or chopping samples), but it is a device that has a lot of functions and quirks that make it both very easy and enjoyable to use, and very inspiring/deep at the same time. Instead of being very capable at making what i want it to make, like the mpc is, it challenges me and inspires me to make music that is different from what i planned, and sounds unexpected and original. It is far superior to the mpc in aspects like its synth capabilities, sequencer options and sound shaping abilities. Also its basic sound is way better then the mpc, as well as its effects.
In conclusion: if you want a reliable all rounder which is very playable- go with the mpc. If you want a device which is more like a very inspiring mad labratory which might lack some functions a daw can compensate for, but gives you options you never even thought of: go with the dt. I use it to make sample based hiphop and its great.
