I'm a bit late to the party on this one, as it was released awhile back, but if you missed it as I did, this is the latest product from Sugar Bytes, who are known for their unconventional effects. Guitarist claims to be a complete solution for emulating electric guitar on your Mac or PC. Sounds kind of interesting. Here's what they have to say about it:
" Absolutely convincing guitar riffs, combined with amps, wah pedals and effects. The actual guitar player has been transformed into a step sequencer system that allows control about playing styles, chord progressions and song structures. Guitarist can be played live as well, with just two fingers you can combine chords and patterns easily. You can choose from factory chords or just create your own chords on the fingerboard. The Action Section allows you to tweak the sequence in realtime and apply timestretch, looper or other crazy effects. Guitar players, keyboarders, producers, Guitarist is the new solution when guitar tracks are needed."
