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.
