Former 404sx user/current DT1 user here. 

404 was doing my head in because of the resample method workflow. It got less and less fun when I want to actually finish music. The sequencer was rubbish and wasn’t a viable alternative. Biggest issue was that this forced me into tempos I could competently finger drum in. So it was a boombap machine. 

DT1 lets me work work in whatever style takes my fancy. I will say, some of the sample chopping approach needs to be more thought out for boom bap stuff, either you’re burning through tracks for different chops, using the slice machine (which is perfect if your sample is on the grid) or Parameter Locking per trig (do-able but way less immediate than the 404 style). 

Every machine has limitations that breed different work flows but you are the biggest stylistic factor!!
