VSL Horizon Acoustic Guitar is a fave right now. It sounds so great on rhythm section parts, such a nice perfect room setting and very intimate.
Larry Seyer Acoustic Drums are really fun, and are unbelievably expressive and perfect sounding.
Black Grand, ambient version, is a great jazz piano.
Notre Dame de Budapest Organ Samples are KILLER.
Scarbee Rhodes and Wurlie...sweet.
Sonic Implants Brass
Dan Dean Woodwinds, combined with GigaPulse.
Giga 3.0 and Gigapulse...just loving it.
