Specially noteworthy are the two Gretsch kits (900 MB of samples with 10 velocity layers per sample), as well as the drag 'n' drop ability for sequencers, the humanizing functions and the processing (reverb, limiter). And let's not forget that it is compatible with VST, AU and RTAS under Windows and OS X. Price: $119."
