Hi Danny,
Thanks for your input here, I really appreciate it.
I doubt if I'll be able to play my own guitar too well to be honest. It's more of an ornament I'm afraid, which is embarrassing, but there you go. That's why I thought I try to use my MIDI programming skills to try and emulate what I want to hear instead, but so far I am failing in that too.
I've watched some of the vids and listened to the mp3 files and SC Guitar is very good indeed. But I bet even that takes some patient programming to get the best out of it. I didn't really want to go down the sample route, only because I had invested in the physical modelling route, and if that fails I will probably give up and keep to doing what I know best. I just thought I could produce a kind of electro/djent fusion, no vocals, perhaps just a token vocoder vocal here and there.
But I won't give up just yet. The Strum VST is not in the same league as SC, by the looks of it, but you can still use a certain amount of articulations. I'll experiment some more and, if I manage to create something half decent I will post it on my soundcloud page :-)
