Great little sequencer the DOT, pairs well with a Robaux LL8, I like that the DOT lets you program ratchets and you can control Euclidean sequences with CV for a constantly moving set of rhythm. Programming it can be a little boring but its great for little fills and background percussion, I also use one channel as an Accent pattern on the Patching Panda Hatz.
If I was going to give a negative about the DOT it would be that the Trigger outputs could be a bit stronger, and the Channel mutes should come up first on the Long Press Encoder knob.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
