About This File
This is an example of using the step sequencer within a Performance to allow the optional foot pedal to do things beyond the standard functions supported directly by the XW synths. You can read about how it works in section 5.2.3 of The XW-P1 Companion, Volume 1 (Rev 4 or later). This example merely switches between tones in two zones but you can use it as a template to do something more useful. It should work on both XW models: P1 and G1.
There are two required components in the zip file: a Performance and a step sequence. Load them where you want to in your XW synth. Now edit the Performance to point to the step sequence.
