You know the saying about there being two kinds of people: those who have lost data and those who will. This article will give you the step-by-step process of backing up your YC Series Stage Keyboard. It will also share how to execute a Factory Reset and update the OS. This is great if you’re playing a backline or borrowed instrument.  

Backup File

• Connect a USB flash drive to the USB [TO DEVICE] port.
• Press [MENU] and turn the Encoder Dial to “File” and press [ENTER] (press down on Encoder dial).
• Select “Back Up File” from the list and press [ENTER].
• Choose “Save”, select “New File” and press [ENTER].
• Name the Back Up File using the letters “YC” “YYMMDD” format (e.g. “YC251208”). See the graphic below for character entry instructions:

• Naming tip: here’s a quick tip that we use. It helps if you have multiple backup files on a single drive as everything will alpha sort by instrument and the most recent save sorts to the end.
  • YC for “YC Series”
  • YY = two-digit year, MM = two-digit month, DD = two-digit day
  • Followed by short descriptive text like “Jazz,” “Cookies,” “Brian,” whatever helps! Example: YC240813 BA Jazz

Factory Reset

IMPORTANT: BEFORE EXECUTING A FACTORY RESET, CREATE A BACKUP FILE! All User Live Set memory will be deleted, and YC will be restored to its original out-of-the-box state. BACKUP first to avoid losing content.
