For a while, the only software I would use as a synthesizer was VCV Rack. I’ve expanded my horizons a bit since Bitwig came out with the Grid in 3.0, but generally I’ve used Bitwig for recording, mixing, and mastering (rather than arrangement or performance). I haven’t used Bitwig with VCV for a little while now, but generally I use them together, which is handy since I tend to rely on the DAW for multitracking as well as hosting and capturing MIDI and routing CV between hardware (through MIDI as well as CV via the ES-8) and VCV or other pieces of standalone software (often through loopMIDI) and then recording that as well. As far as I’m concerned, it’s all fair game, but a proper DAW is probably good to have in the middle of everything in order to capture as much information as possible, but it can be fun and interesting just to fire up VCV on its own in order to better approximate actual modular synthesis.
By the way, Bridge in VCV does still work and, according to the documentation, should stick around until 2.0 when a VST version of VCV is supposed to be released (albeit without support, so I suppose it could hypothetically run into problems before then).
