Both M:S and DT are solid boxes that have their own strengths and weaknesses. I know DT is the more advanced machine but it comes at a cost of complexity and it could be argued that the M:S is more immediate and easy to use. Even though they share the same Elektron sequencer DNA there are some differences that are more than skin deep.
For example, the sample management is different, With the DT you need to load samples into the “pool” of a project to be able to do sample locking (switch samples on different steps, a key part of Elektron workflow) whereas the M:S can lock any sample on the unit onto any step on any project so you don’t need to plan ahead. Also, the knob-per-function design on the M:S can makes things more immediate as you don’t have to switch pages to reach different behaviours. It has more simple sound design tools for sure but they are right in front of you. So with the filter you have a dual LP/HP filter on a single knob (much like some DJ mixers) and it’s always there. Same with delay and reverb send, sample start and length, pitch, LFO speed etc so as a performance/jamming tool I think it’s probably better in many ways. The DT has the more advanced tools but you have to navigate through different pages of controls for the 8 knobs. It’s not a criticism as such, but it’s a different workflow.
If the ability to stream each track into your DAW is a vital feature for you then the DT wins by default but don’t overlook the M:S if you want a cheap, fun tools to make beats - it’s a great little box. I think we can all agree that the joy of Elektron boxes is that they can do a hell of a lot more than the features might suggest.
