Roland • MC-307 Groovebox

The new MC-307 is the Groovebox aimed at DJs. Like the other MC's, it is a robust pattern-based sequencer/sound module with 800 patches, 40 rhythm sets and 33 effects. However there's a new "Turntable Emulation" mode which affects the pattern tempo and pitch in much the same way as a turntable's speed fader. There are even Hold and Push buttons which let you emulate the slowing, speeding, stopping or flicking of a record by hand. This lets you control and 'beat-mix' your Groovebox just as if it were a vinyl record!
The MC-307 has all the familiar sounds of a Roland Groove product, plus many new sounds, patterns and effects. There is also a new Grab switch with multi-effects (including Isolator) for creating interesting rhythmic effects. It does not, however, have the D-beam controller as the MC-505. But it does have a nice big backlit LCD display unlike any previous Groovebox.
The sequencer comprises of 7 instrument parts plus one rhythm track. Each is mute-able for dropping sounds in and out of loops on the fly! Perfect for DJs working the energy on the dance floor! The Real-time Phrase Sequencer (RPS) offers 470 instant patterns in all sorts of dance music styles!
For DJs, the MC-307 gets 5-stars. It's the ultimate performance tool for any dance music DJ! However, as a for the rest of the synth-community the MC-307 is nothing we haven't already heard before and will be of little use, especially when compared to the MC-505. The MC-307 has already been used by BT.
I love it. At first it seems impossible to overcome the complexity of programming it but once you get used to ie (and read 10x that goddamn thick manual) you can get some freakin awesome tunes out of it.
House, Techno, Electroclash, EBM and even ambient. You can get make it all.
