Sonoma Wire Works (, makers of
RiffWorks recording software and the FourTrack and InstantDrummer
iPhone Apps, has acquired the entire Submersible Music product line,
including the DrumCore and KitCore software and drum content.

Submersible was created by Paul Allen, the philanthropist and
Microsoft co-founder, to help him in his own songwriting. DrumCore
( gives songwriters and composers access to
grooves and instrument sounds of over a dozen famous drummers and
percussionists. It includes a groove library of both audio loops and
MIDI files plus a VST/AU/RTAS software instrument loaded with the
drummers’ sounds for Mac and PC systems. KitCore and KitCore Deluxe
offer most of the features found in DrumCore, but include only the
MIDI content (grooves and a drum instrument).

Content is arranged into song-like GrooveSets, that group related
loops, fills and variations together and supports typical song
variations for verse/chorus/etc. It supports searching via metadata
that includes drummer, musical style and “Feel,” including shuffle,
swing, 1/8th, 1/16th, etc. Grooves and instrument sounds can be used
in most popular music/recording applications.
