If you do a lead library, what types of articulations do you plan to include?
Personally, I would like these features (other than the obvious sustains):
RR (of course
Ability to be double-tracked (a lot of metal bands DT their leads)
Vibrato, harmonics and pinch harmonics
Palm mutes, slides, hammer-ons/pull-offs and Wah-wah
I would also like to see pitch-bends as well.
Vibrato could be controlled by modwheel CC1, wah with CC2, and pitch bends controlled by either CC3 or a pitch controller (not a MIDI expert, so yeah). Harmonics and Pinch harmonics could be controlled as part of the velocity layers: 110-127 = pinch, 95-109 = harmonic, 65-94 = sustain, 35-64 = hammer/pull, which alternates, 20-34 = light palm mutes, and 1-19 = hard palm mutes.
Or something like that, but 6 velocity layers divided about evenly should be awesome for leads. Slides could be like how it currently is with Shreddage X, where you can choose whether to have slides or not, and pick the slide time. Maybe, just maybe, a keyswitch so you can go quickly from slides to being able to play chords and such (no slides).
Just a thought...
Oh and I got most of my ideas from this Yamaha Pacifica free lead guitar library. The only problem is that it doesn't sound too superb and its tremolo picking sounds a bit machine-like because it lacks sufficient RR.
