The Mimetic isn't all that difficult to use once you crack the manual or follow a couple of Youtube tutorials. The "O" input stands for "Origin" which takes the sequencer back to the very first of 16 steps. The "N" input stands for "Next" which will advance the sequencer to the next step. What I find nice is sending it a rhythmic pattern as well as a reset. There are additional inputs that control which step to advance to or even randomly. Connect Steppy to a few of its inputs and have a good play. I'd try one CV out for pitch info, another to control the cutoff on your filter, and a third to modulate something different. It could even go to a secondary VCA to give you an accented note if your envelope can take modulation (even raising the volume of a VCA is a good trick if you put a second VCA after your main VCA controlling amplitude).
In my experience, there are some modules that seem like duds on your first or second play with them. Then you find yourself really exploring them later on and finding "that's not half bad... wait... this is fantastic!" So give yourself a few weeks to get into the workflow.
I'm not a big fan of the Disting and the six double-sided print outs I have to keep around to remember what each function does. I like everything about it except the interface. Maybe it's the PTSD from working with an Ensoniq Mirage in my late teens. :)
Once you get the fever for some new modules, check out the micro version of Ornaments & Crime. Also, take note of anything you're using a lot in the Disting. That might give you some fodder as to what dedicated module(s) you might want to include in the future. Example: you find yourself using the quantizer program a lot.
