Short answer: no, you can’t use something like Silent Way with crow (to my knowledge), but you don’t have to use any monome software either.
Long answer:
Expert Sleepers devices appear as USB audio devices, a somewhat complex protocol that’s necessary for real-time streaming at the frequencies ES modules are designed for. This means that lots of DAWs and so forth can send CV or audio data out to an ES-8 or ES-9 and it will spit it out as-is.
crow does not have quite the same design in mind. crow is not a DC-coupled audio interface, just a Lua evaluator behind a plain ol’ serial port: you send it some Lua, it executes it and sends back results. Maybe running some of that code interacts with crow’s CV jacks. This is a really old-school communication mechanism that is comparatively slow, but also dirt simple to talk to, so it’s straightforward to add crow support to lots of other software environments (Max, pd, anything that can talk to a serial port, which is more or less any programming environment made in the last 40 years).
You can manually set crow’s output voltages by sending it a chunk of Lua code like output[2].volts = 2.5, but you can’t really stream voltage values to/from crow at audio rates. Instead, you can script crow to generate LFOs on its own, or react in some way when an input CV crosses some threshold voltage, or whatever. To my knowledge ES devices don’t act autonomously like this, they need to be tethered to a computer, whereas you can upload a script to crow and then use it on its own as just another Eurorack module - a module where you get to define whatever CV processing / generating functionality you want.
