- REGISTER alternates 2 preset patterns, select the first one then REGISTER and then the second one
- FILL IN insert a fill-intro pattern every 16/ 12 /8 /4 /2 (or MANUAL) choosing from the knob selector.

info MODS & MAINTENANCE common issues are the worn-off push buttons that often needs to be replaced. however it is possible to clean them, but extreme care is needed to disassemble the tact switch - NOT an easy task.

There are many hardware modification of the beatbox around the net. Most common is Trigger point for external control (you can listen to some audio into the DEMO section below).
