"Well there are some things that a lot of computer software VSTs cannot do unless they are specifically programmed to do so"

That describes every problem that a computer might be called upon to solve.

The state of analog synthesizer modeling is very, very good, including emulating modular synths (Arturia, Native Instruments, and many others produce competent modular emulators). I say this as someone that has owned a number of analog synths, and, if I had the space for them (I live in a travel trailer) would still own them. Nonetheless, the notion that there are sounds unique to analog synths is mostly superstition at this point.

It is fun to play with it in hardware. But, it is not necessary to play with it in hardware.
