This is designed to provide the Reason user with a full-bodied acoustic guitar sound - and it succeeds.
By taking a premium quality guitar and sampling every note of every chord, AudioWarrior have created one of the best sample-based guitars we've heard.
Because the chords are sampled note-by-note, truly realistic strumming is possible. This 600MB ReFill uses 24-bit samples and includes most chord voicings, mutes, harmonics, hammer-ons, slaps and thumps.
Combinator patches enable you to map chords across the keyboard and also easily apply effects. Excellent.
