Designed from the ground up for DJs, the MC-307 Groovebox is an integrated electronic music workstation for pounding out serious grooves live or in the studio. Turntable Emulation controls make adjusting a pattern's pitch and tempo like mixing vinyl records, while a streamlined user interface makes operation easy, even for those having little or no experience with musical instruments. 

If you can spin records, you can make music with the MC-307 Groovebox. Designed from the ground up for DJ’s and live performance, this integrated groove music workstation makes it easy to pound out some serious grooves, live or in the studio. A new Turntable Emulation slider makes adjusting a pattern’s pitch and tempo just like mixing vinyl records, while a streamlined user interface makes operation easy—even for those having little experience with musical instruments. More sounds and all-new patterns make the MC-307 the hands-down Groove champion.

Turntable Emulation Captures the Feel of Vinyl To make playing the MC-307 more like mixing records, Roland created Turntable Emulation. Based on a turntablestyle slider design, this new controller allows DJ’s to adjust a pattern’s pitch and tempo (together or independently) on the fly, making it easy to integrate the Groovebox into live DJ sets. Using the Push and Hold buttons, you can instantly "nudge" a pattern to catch up with the beat of another source or "drag" it for perfect beat mixing—much like using your hands on a vinyl record. In fact, even those who have never played a musical instrument can use the MC- 307, thanks to its ultra-intuitive interface. Say "goodbye" to confusing layered menus and "hello" to a graphic LCD linked to four function buttons for quick navigation of all parameters. Slammin’ Patterns and Sounds At the heart of the MC-307 is a 64-voice sound engine with 16 MB of wave memory—twice that of the MC-505. In all, there are 800 Preset Patches and 40 rhythm kits covering the entire spectrum of dance music—from lo-fi hiphop to hardcore futuristic techno. All of these sounds can be tweaked in realtime using dedicated knobs for Cutoff, Resonance and LFO, or any of the four assignable control knobs and Grab switch. With 240 all-new Preset patterns— including techno, house, hip-hop, lounge, Latin, and drum ‘n’ bass—the MC-307 will sound fresh for years to come. Of course, there’s also plenty of room to program User Patches and patterns.

Innovative Effects and Killer Grab Switch The MC-307’s onboard effects processors are truly stunning. They include dozens of ways to spice up individual parts or tweak an entire mix, including flangers, choruses, Lo-fi, Slicer and much more—all of which can be sync’d to BPM. Borrowed from Roland’s popular DJ- 2000/1000 Professional DJ Mixers, the MC-307’s Grab switch allows DJ’s to tweak effect parameters in realtime much like a transform switch. When used in conjunction with the new Isolator effect, the Grab switch allows users to completely cut the low, mid, or high frequencies with rhythmic precision.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
