Introduction

Product Description

Upgradable Sounds

The PX-7 Command Station is a hybrid drum machine featuring a powerful
sequencer and 128-voice synthesizer. The E-MU sound engineers spent six
months meticulously sampling acoustic drum kits in professional studios
around the U.S. to build this diverse collection of drum sounds. These drum
kits have been optimized for the PX-7's advanced synthesis architecture,
with multiple cross-switch layers built into each instrument. PX-7 also
contains three additional, user-upgradable sound SIMM sockets, allowing
you to mix and match sound sets according to your needs. New sounds can
be added as easily as plugging in a new 16MB or 32MB SIMM module.

1024 Presets & more

PX-7 contains 512 user presets and 512 factory ROM presets, but it can be
expanded with literally thousands of ROM presets. (ROM presets are

automatically added when sound SIMMs are installed. As an example, a 32 MB
SIMM may contain up to 1024 ROM presets.) PX-7’s Sound Navigator makes it

easy to find the exact sound you want. It’s powerful, yet simple to use.

Multi-Function Controllers

Multi-function buttons allow you to trigger sequences, arpeggiators and
loops internally or on any of your other MIDI devices. They can act as Note
Inputs for Grid or Step recording, Track Select, Mute or MIDI Trigger
buttons (latched or unlatched).

Sixteen real-time controller knobs are also multi-function controls. These
knobs make it a snap to edit and modify internal preset parameters.
Another useful mode allows the knobs to control volume and pan for all
sixteen MIDI channels. These controllers are fully programmable and can
control internal preset or other MIDI equipment on multiple MIDI
channels. They can be programmed to adjust multiple internal parameters
at once, allowing complex levels of control. For example, a single knob can
simultaneously turn up filter cutoff, while detuning one sample, and
adjusting the release time of the volume envelope. Virtually every synth
parameter in the PX-7 is controllable using the real-time knobs or by any
internal or external control source.

PX-7 Owners Manual 1

Introduction

2

Super Sequencer

PX-7 contains a powerful, yet simple to use 16-track interactive sequencer.
You can record in real-time, step and grid modes and can switch modes
without ever stopping your creative flow. Sixteen dedicated Mute/Select
buttons allow you to add, monitor and modify parts on the fly without
cumbersome menu scrolling. It’s never been this easy to lay down your
ideas. The PX-7 Command Station can store over 300,000 notes and you
can import and export standard MIDI files (SMF) to and from your Mac or
PC using E-MU’s E-Loader program.

Multi-Channel Arpeggiators

PX-7’s Rhythmic Pattern Generator/Arpeggiator can play up to 32 synchro­nized arpeggiator patterns at once using a different sound for each! Arpeg­giators are yet another way to create unique and unusual drum patterns.
Patterns can be edited using pattern flow commands such as: delay for 2
bars, play for 4 bars, hold for 2 beats and repeat. You can program or
download 100 user patterns in addition to the 200 factory patterns.

Ultra Powerful Synthesizer

The extremely flexible yet easy to use 4-layer synthesizer voices make it
easy to build sounds of any kind. Layers can be switched or crossfaded
using key position, velocity, real-time controllers or any modulation source.
128 voice polyphony ensures that you can play and sequence the most
complex material. PX-7 also contains 50 different 2nd to 12th order
resonant & modeling filters.

Sixty four modulation sources include three multistage envelopes and two
LFOs per layer, as well as full MIDI control over virtually every parameter.
The digital patch bay, with 24 cords per layer, (and 12 more cords per
preset) lets you connect modulation sources to 64 destinations in any
imaginable way. Synth parameters as well as arpeggiator and BEAT tempos
can be controlled from PX-7 internal clock (or an external MIDI clock). Up
to 8 LFOs and 12 envelopes can be perfectly synchronized at different rates.

24-bit Effects

Once you have created your preset, you can add richness to your sound
using PX-7’s 24-bit stereo effects. You can choose a different effects setup
for each preset from over 60 algorithms. PX-7’s effects section is actually
two separate effects processors with control over each wet/dry mix level on
four effects sends. Effects Processor “A” contains primarily ambiance
algorithms like reverb and delays, while effects processor “B” contains
primarily spectral algorithms such as chorus, flange, phase, distortion, and
delay. Effects can be linked to each preset or used globally to further
enhance your sound.

Other features include multiple solo, voice assignment and performance
modes for expressive control, 12 user-definable alternate tunings, and, of
course, an extensive MIDI implementation.

Audio Outputs

The Sub 1 and Sub 2 output jacks are stereo jacks. The tip of each jack
(accessed when a standard phone plug is inserted) connects to the left or

If you insert a stereo plug into one of the Sub Outputs, the ring of the plug
serves as a signal Return which sums into the Main outputs.

Therefore, the Sub 1 and Sub 2 jacks can serve as effect sends and
returns in order to further process selected instruments and then
return them to the main mix.
