E-mu’s drum-centred PX-7 Command Station appeared in 2003. A June shipping announcement described a new drum sound set, a pattern sequencer and Version 2.0 software in the Command Station format.

The machine in the record

Modal Plane / the machine to keep.

Modal Plane identifies a loaded E-MU PX-7 as the machine they would choose first if starting again. It is an ownership-and-preference account, not a named recording credit, and it makes a good case for the obscure expander as a lasting creative companion.

Drums under thirteen pads

Play a rhythm on thirteen velocity-sensitive pads, then build it into a pattern. The PX-7 puts acoustic and electric drums and percussion into a 32 MB ROM sound set, with a 128-voice synthesizer behind them. Its starting material is the installed sound library: the player edits and sequences those sounds rather than recording an incoming drum hit.

Keep the pattern moving

The sixteen-track sequencer offers real-time, grid and step recording. E-mu’s manual says the player can move between those methods without stopping. Sixteen Mute/Select buttons bring tracks in and out or select a part for work, so a running pattern can become the place where an arrangement is made.

A sound set, not a fixed kit

Presets can contain four synthesis layers, switched or crossfaded by velocity, key position or a controller. Filters and envelopes reshape the installed sounds. Three additional ROM sockets let the player add other sound libraries; this is expansion through sound modules, not extra time for recording samples.

Sixteen knobs for the wider setup

The sixteen programmable knobs can edit internal sound parameters or address other MIDI equipment. They also serve as volume and pan controls for the sixteen MIDI channels. The PX-7 can therefore work on its own sounds while acting as a sequencer and control surface for a larger setup.

The drum-centred Command Station

E-mu showed a pre-production PX-7 at the March 2003 Musikmesse. The June announcement reported shipping with Version 2.0 software at £699 including VAT in the UK and $995 in the US. Later announcement and dealer coverage continued the drum-centred description. Its drum library joined the shared Command Station operating system, whose Version 2.00 changes E-mu documented in a separate addendum.
