Moldover intros his unique MIDI controller instruments, including The OctaMasher, SyncoMasher & MiniMasher:

Born from the union of a passion for controllerism, and the love of community-collaboration, Moldover’s jamboxes are some of the most radical and innovative instruments he’s ever created. The OctaMasher, The SyncoMasher, and The MiniMasher are completely unique designs; each explores a different realm within the multi-player universe. Like jukeboxes in the 1950s and boomboxes in the 1980s, jamboxes are now playing a crucial role in the new explosion of social music and culture.
