Notes Command Station
In 2001 the Proteus line of modules was repackaged in the form of a line of tabletop units, the XL7 and MP7 Command Stations, broadly similar to the rack-mounted 2500 in features but featuring touch-sensitive pads suitable for recording drum patterns.

The hot new XL-7 is a desktop sequencer module version of E-mu's Xtreme Lead-1 Electronica and Dance oriented sound module. You may recall that the Xtreme Lead-1 module itself was a new and improved Techno synth based on the popular Audity 2000 module. Like the Xtreme Lead-1, the XL-7 uses the same sample-playback synthesis engine as E-mu's Proteus 2000 sound module. The XL-7 and all its Electronica synth sounds and beats can also be found in a sleek keyboard version called the XK-6 Xtreme Keys.
