PX-7 Owners Manual 169
Programming Basics
This chapter explains how PX-7 sounds are constructed and contains
important background information on how to create your own custom
presets.
Your initial involvement with PX-7 will most likely be using the existing
presets and selecting MIDI channels. While the factory presets are very
good, there are some things you will probably want to change eventually,
perhaps the LFO speed, the filter frequency or the attack time. You may also
want to make your own custom presets using complex modulation
routings. This instrument will do far more than you can imagine and whole
new classes of sound are just waiting for you to discover them.
Each preset can consist of up to four instrument layers. Each of the four
layers can be placed anywhere on the keyboard and can be crossfaded or
switched according to key position, velocity, or by using a real-time control
such as a wheel, slider, pedal, LFO or envelope generator. A preset can also
be “linked” with up to 2 more presets creating additional layering or splits.
PX-7 has an extensive modulation implementation using two multi-wave
LFO’s (Low Frequency Oscillators), three multi-stage envelope generators
and the ability to respond to multiple MIDI controllers. You can simulta-
neously route any combination of these control sources to multiple desti-
nations.
There are 512 user locations (User Banks 0-3) available to store your own
creations or edited factory presets. It’s easy and fun to edit or create your
own unique presets.
