Thats my personal experience and may vary for others:
I purchased the Deluge for my Digitone as sequencer. I tried to get around with the non existent kits on the Digitone with it. Plan was: Use empty pattern on the Digitone as Kits, and Sequence it with Deluge. Well, didn’t worked out: Hanging notes?
Elektron stuff and Midi is something that does not work for me. I really don’t want to invest any more time in it. Also my Octatrack is bad at midi sequencing. If I try to sequence my Sledge it drones away. I don’t want to invest more time into it, i want to make music and not a technical fix it degree.
Deluge is imho perfect for sequencing - it’s small, you can drive it with battery, and you can change synth tracks easy into midi tracks to drive other synths with it (if it’s not an Elektron). It’s perfect to sketch ideas, and then decide what synth you want for bassline, etc.
But if you just learn the elektron sequencer - that means you want to have that sound of this elektron device and don’t need to sequence other stuff, than elektron is perfect. Those boxes really, really have good internal sequencers!
Just sync those boxes and ignore other midi stuff if you want to avoid issues with elektron.
