I'm very pleased to announce the upcoming release of Lemonstrum 3: Acoustic Guitar Strummer this October 1, 2009. The feature set will be posted soon.
Lemonstrum 3 turns your keyboard into a trigger board, in the sense that the chord does not have to represent the key trigger (eg. you can assign chord F to key trigger C). It has 12 triggers (C-B), and comes with a complete set of power-chords assigned to each key.
You can also use your own guitar samples. It's easy to load samples directly into Lemonstrum 3 and transpose them. Listen to the audio samples below.
