'Virtual' Sound Canvas is likely not going to work anymore. (Question 1 & 4 of OP)
At least not the one PGMusic supplied in years gone by.

There are others out there, and Sonar/Cakewalk comes with a nice one that *can work in other DAWS. Some people have installed Sonar/Cakewalk just to have the synth, and that's not a terrible option so far, given it's free.



I do not work here, but the benefits are still awesome
