Seeing Kristian Røstøen posting a remix preview here kinda motivated me to get back to work on my own first try. I left it because I couldn't find a good lead instrument, and now I'm hoping someone can get me back on track

I'm doing a simple tune by Link/Vibrants in Renoise, and I guess something like a jazzy organ / vibraphone / guitar thing would suit it pretty well. Some filtering effect, etc. would probably be nice, but I should probably add that in mixing?
What sort of instruments or plug-ins do people recommend, and do you use default sounds, or spend heaps of time on tweaking your own, optimized instruments?
Any good examples out there?
