Oh, Audacity...I have fond memories of that DAW, if you can even call it that. That is a very interesting and weird VST you've found. It's actually quite believable and has pretty convincing articulations that an actual guitarist would use -- not sure if you or the plugin does that, but it sounds cool! Either way, you did a great job with playing your midi controller like a guitar! Nothing stood out as being "unplayable" :D
Very interesting piece overall. This would actually make a great backdrop to a scene in an old western film or game!
