Like the MC-808, 909, 505, 307 and 303 (phew) before them, the MC-707 and 101 are self-contained loop-based music production boxes. That means there's no need to connect to a computer or plug in any additional instruments. They're synthesizers, drum machines and sequencers all in one.

The larger, and more expensive, MC-707 can not only emulate sounds from Roland classics like the TR-808, TB-303 and Juno (yes, Roland's love of certain numbers is unnecessarily confusing), it also has sampling capabilities for expanding your sonic palette. All told there are eight sequencer tracks for building melodies, drum patterns and basslines. Plus a host of integrated effects for filling out your sound.

The MC-101 has all of the same built-in sounds, but scales things back to just four sequencer tracks. But, unlike its big brother, it's portable and can be powered by four AA batteries, for beat making on the go.

Both instruments have plenty of knobs and faders for hands-on control. Plus they have 16 pads for finger drumming and programming the sequencer. Their design is definitely reminiscent of Roland's recent drum machines, like the TR-8S, but slightly less garish, which is nice. (Don't worry, they're still kinda garish.) The MC-707 and MC-101 will be available later this month for $1,000 and $500 respectively.
