@cogsy: Just run some plucky/rhythmic synth part with space in between notes into Mozaic 3/4 on triangle wave. You should get something like a musician playing along with you, it’s the thing that Microcosm does best imo. Build a track on that foundation, not that much else needed.
Haze 3/4 are good for pads/more atmospheric structures, to give it a bit more of a vibe.
For a more classic delay, pattern delay is really useful and has georgeous stereo panning. Set it to square.
In general, keeping activity and repeats at around 9 o clock always delivers the best results for me. Avoid the reverb. Tame Microcosm with mix and filter.
Great for transitions: Record a loop by just holding down the most right foot switch, increase mix to max, then crank the reverb and then slowly let the sound fade out by closing the filter.
Always record when exploring. You might not be able to reproduce stuff. If you have something nice going, take pictures of the pedal. And record variations that you could use for snippets, also a fullly wet version. It can be good at giving you textures that are in the background of a track and filtered out via a DAW, that really fit the track without giving away its origin from one of the actual track elements. You could also use the sample and play it on a keyboard, I‘ve made a few pads this way from more ethereal sounds.
I’ve posted some examples in this thread, so you can judge yourself if my results are something that you like. Here’s also something from another thread that shows the Mozaic as playing along with you:
