When I first got into Eurorack in fall 2016, I saw the Teletype and thought it was kind of goofy – a computer to put in one’s rack, for those who don’t like computers? I realize now that I missed the point. 
My project in the last few months has been to explore different sequencing types. When I write melodic stuff I do most of my sequencing in MIDI – basic step sequencer and standard tracker stuff in hardware doesn’t really appeal to me that much. But I do like working with unquantized sequences, gate manipulation (Euclidean patterns, dividers, logic etc.), combining multiple gates in a mixer to create CV patterns, etc.
I had an Ornament + Crime fairly early in my modular journey, but was using it just for envelopes and wasn’t entirely happy with it, so I sold it. Lately I’ve been thinking about getting one again to do quantization or Euclidean sequences – but I don’t much like the “or” part of that, the apps aren’t exactly what I need, and while I am a coder I don’t really want to get deep into modifying firmware.
Enter Teletype… I realize I could set up scenes that have multiple channels of Euclidean patterns, stored patterns, shift registers, dividers, multipliers, logic etc. and simultaneously quantize a pitch CV (or multiple CVs with TELEXi). And then also issue some commands to W/ for probably all kinds of fantastic fun – hopefully synchronizing cues to tempo and switching between them, etc.
I think I have talked myself into it at this point.
