NuSofting has released DR-660 Kits, a DK+ Library extension featuring the default kit for the internal DK+ 21 Styles, plus 28 ".dk+" kits based on the DR-660 factory settings.
The original Boss DR-660 featured the usual 78, 808 and 909 and Linn type sounds along with other electronic kicks and snares, a number of "acoustic" sounds, congas and bongos, and of course those 80's gated snares.
The DR-660 sample collection for DK+ features all 255 hits from the Boss DR-660, a selection of which are grouped into 28 ".dk+" kits based on the DR-660 factory settings. In total, you will find 51 bass-drum samples, 76 snares, 18 cymbals and hi-hats, 71 percussive and ambient hits, and 40 toms.
