The XP80 has a powerful and versatile arpeggiator. It has 33 different arpeggio styles - keyboard, bass, rhythm guitar, etc. Within each style you can manipulate the motif, beat pattern, accent rate, suffle rate, tempo and patch selected. There is a way to save your arpeggio settings to disk. Note that if you've changed any of the other system parameters such as tunning or MIDI control, these parameters will be overwritten with the data saved in the SVD file.
Tones are samples in digital form.
Edited patches can be saved to the users bank. Be careful not to delete a patch you want to keep. The volume of patches can be controlled via several different parameters. Some expansion boards do contain drum kits in the patch banks that can be routed through any other track. Scroll down for instructions on slaving your unit.
