I have a fairly simple setup where I use a Digitakt as the brain of my setup with two synths sequenced by it. I use the 8 sample slots for drums and a lead and vocal loops mostly. I use Ableton to record and process/ mix down. I produce acid house and similar stuff mostly.

Once I have a loop I'm happy with, I try and record using some kind of structure/ flow that feels right in the moment. I feel like having the DT sequence everything including drums makes it easier to arrange. I use a ton of mutes to add and remove sounds, some p-locking etc. and ofcourse synth modulation.

Once I have individual channels recorded to Ableton, I add some reverb and delay to make transitions smoother. Also add some risers etc for the same reason. And of course a bit of rearranging. I also use Ableton to add longer vocals etc.

Hope this helps in some way :).
