Hmmm… I can’t say there’s anything essential between the two that I’ve come across, but they both can perform a lot of ultility functions that certainly can work together.
I will say quantizing the morphing LFO shapes can be rewarding. I was using that for my sequencing for a while, but that isn’t O_C specific.
Stages is less literal in the sense that O_C goes into a mode/modes with clear labeling and really only one purpose; where as each channel of Stages can be combined with others to do a big laundry list of things depending on your creativity? So I’d say the the important thing is to spend time figuring out the segment types and how you can sort of treat it as a “sub modular” enviroment in and of itself. I can get pretty stuck in my ways with it; it’s easy to get stuck using it for its most basic purposes.
I occasionally consider getting rid of it, but the modules I’d need to replace it just take up a lot more space. I will add that despite the fact the manual spends a lot of space explaining how to make every envelope under the sun, envelopes are my least favorite part of the module. They’re painfully unintuitive to me, and adjustments never feel like they do what I expect, despite having used the module for that purpose extensively. They’re just not super… musical? It can also be very difficult to repatch live because of the way the left to right gating behaviour works.
That said, the synced LFO’s are killer – which is also clock dividing! Having lots of sample and hold with slew is nice. You get a bunch of offsets if you want 'em. It’s also handy for tiny sequences. One or more of those things end up in most all of my patches. Despite my criticisms, it’s an indespensible module that seems underappreciated.
