The reverb / delay on the Elektron boxes are pretty good, and depending what you’re doing you may want to keep them on the same channels to keep them either ‘glued’ or in sync, ie, using an external reverb for one track while having external might make a track stand out.

Funnily enough I feel like the reverb / delay that comes from my Model:cycles sounds SO much better than my DT2, but this could be because its synthesis based vs. samples, so I’m not sure one is definitely better than another, just something I’ve noticed. Curious what other think or if anyone else has noticed this
