E-mu XL7 Command Station (2001–?)
The E-mu XL7 Command Station is the flagship of E-mu's Command Station series. It was introduced in 2001 as a music production workstation for live performance. At its core it's a Proteus 2500 sound module with a hands-on control surface bolted on. The XL7 is basically the MP7 with more buttons and knobs, and it sits above the MP7 in the lineup.
The synth engine is ROM-based. It draws from 16 MB of preset ROM holding 1,320 sounds, with room for 128 user presets. Polyphony is murky. E-mu's own materials list both 32-voice and 128-voice figures, and the record doesn't cleanly resolve which is correct. The unit also carries 32 MB of sample RAM. The sequencer is 8-track and pattern-based, with 32,000 notes of capacity. There are two separate effects processors and a 4-band master EQ.
The front panel is where the XL7 sets itself apart. It has 16 velocity-sensitive MIDI pads and 8 assignable knobs, plus an LCD display, which gives it a groovebox feel. Connections include 8 audio outputs, 4 audio inputs, main unbalanced line outs, a headphone jack, and full MIDI In/Out/Thru. Power comes from an external 12V DC supply. The unit measures 17" x 12" x 4" and weighs 14.2 lbs (6.4 kg).
Period coverage is thin. The XL7 shows up mostly in classified ads rather than reviews. A classified in Sound on Sound (2005, p.266) described a used XL7 as expanded, basically a Proteus 2500, which confirms the lineage. Contemporary reception noted the pads are a bit small and the ROM sounds were already starting to date. The build quality is excellent and the sequencer is very user-friendly. The effects are usable but not spectacular.
The XL7 is now hard to find on the used market. It has a reputation as a classic - a solid, easy-to-use machine for live performance.
