1) I think the Kemper conversion is quite good. What do you find wrong with it?
2) The Stage allows external clocking, if that's important to you. There's also the option to get an audio interface that allows you to do this with the regular toaster or rack (the Universal Audio Apollo stuff does)
3) I'd be really happy to get a VST that would allow me to recall settings in my DAW. That would be killer. As far as a full-fledged VST though, I hope they never do it. If for no other reason than the fact that it would bring down the value of my hardware Kemper.
Has Helix Native devalued the Helix hardware?
