The E-mu MP7 Command Station is a sophisticated tabletop groovebox that combines the acclaimed Mo'Phatt sound module's urban/hip-hop sample library with hands-on sequencing and real-time control capabilities. This late-entry to the groovebox market represents EMU's return to their drum machine heritage while embracing modern dance music production needs.
Featuring a controller-rich front panel with a light-mauve/rich-purple color scheme, the MP7 emphasizes physicality in an era of software-based instruments. The unit can function as either a tabletop module or be rack-mounted in 6U space, making it versatile for studio and live performance applications.
At its core, the MP7 utilizes EMU's flagship Proteus 2000 synthesis engine combined with the complete Mo'Phatt sample set, delivering warm, rounded sounds with rich bass response and punchy character. The instrument offers 128-voice polyphony as standard, along with four additional analog audio outputs that would require expensive expansion boards on other EMU modules.
The pattern-based sequencer provides 16 tracks with up to 32 bars per pattern, supported by 128 factory patterns that showcase authentic urban and hip-hop styles. These professionally programmed patterns serve as both inspiration and learning tools, demonstrating the high-quality sounds and sophisticated programming capabilities of the instrument.
Live Performance Features
The MP7 excels in live performance scenarios with its comprehensive real-time control system. Thirteen velocity and aftertouch-sensitive rubber drum pads are laid out in keyboard formation, transposable across seven octaves. While ideal for rhythm programming, these pads can trigger any of the MP7's preset instruments.
Sixteen assignable knobs provide real-time parameter control in multiple modes:
- Quick Edit Mode: Controls predefined sound parameters including filter cutoff/resonance, amp envelope ADSR, LFO amount/rate, and arpeggiator settings
- Program Mode: User-assignable parameters with MIDI channel routing to any of 32 output channels
- Volume/Pan Mode: Direct control over all 16 sequencer tracks
Sixteen backlit buttons offer additional performance options:
- Track Enable/Mute: Live track dropping with visual feedback
- Triggers Mode: Configurable note triggers with velocity, channel, and latch settings
- Grid Recording: Step-sequencer style programming with visual step indication
Sound Generation & Effects
The MP7 employs EMU's advanced subtractive synthesis architecture with Oscillator-Filter-Amplifier design. Each preset supports up to four layers, with additional linked presets enabling 12-layer sounds or three-way keyboard/velocity splits.
The unique Z-plane morphing filter system offers 50 predefined filter types from 2nd to 12th order, including standard filters plus swept-octave EQ, phaser, flanger, vocal formant, and resonant types. Six-stage envelope generators, dual LFOs with 17 waveforms each, and a 24-slot modulation matrix provide extensive sound shaping capabilities.
Dual 24-bit stereo effects processors deliver 44 reverb and delay types (FXA) plus 32 chorus, flange, delay, and distortion effects (FXB), accessed via four effects send buses with dedicated modulation matrix.
Sequencing & Arpeggiator
The 16-track pattern sequencer supports real-time, step-time, and grid recording modes with automatic loop overdub and seamless mode switching. Song mode enables pattern chaining with an additional multi-channel song track for continuous recording and real-time controller overdubs.
The sophisticated multi-arpeggiator system provides traditional arpeggio modes plus 200 preset and 100 user patterns of up to 32 steps each. These function more like phrase sequencers, with up to 32 arpeggios running simultaneously, each with independent note values while maintaining master clock sync.
Expansion & Connectivity
Three internal ROM expansion sockets accommodate additional 16MB or 32MB sample sets, expandable to 128MB total. Compatible with EMU's extensive sample library including Techno Synth, World Expedition, Orchestral Sessions, and custom Flash SIMMs from E4 Ultra samplers.
Comprehensive connectivity includes main and two sub analog outputs, S/PDIF digital output, dual MIDI outputs, dual footswitch inputs, direct computer connection, and internal power supply. Optional gooseneck lamp connection and rack mounting hardware extend versatility.
