Update history
[ Ver.1.05 ]
[ Bug Fixes ]
The following bugs were fixed.
  • The Rhythm Edit screen freezes during processing.
  • After power-on, the pitch changed.
  • Shortly after start up, the JUNO-STAGE doesn't perform by the setting value of the "Keyboard Velocity Sens." It does by the initial value ( Sens=0 ) in fact.
[ Functionality Improvements ]
  • Even though the bender lever is switched, the pitch of the song part does not change anymore.
  • Reading process of play lists in the USB Memory Player was speeded up.

What you will need to update your JUNO-STAGE
  • JUNO-STAGE itself
  • A computer with a USB connector ( Windows, Mac )
  • USB Memory ( Roland's M-UF2G is recommended )
  • The downloaded update file

Caution when performing the update
  • Never transmit this update data to any product other than the JUNO-STAGE. This update data may destroy the data or system program of other products.
  • We recommend that you back your user data up to USB-memory device before you perform the update. If a problem occurs and your user data is lost, you will be able to restore the data by reloading the data you saved. For details on the procedure, refer to the Owner's Manual.
  • Never power-off your JUNO-STAGE while the update is in progress! If a power failure or similar accident occurs during the update process, the JUNO-STAGE won't be able to start up in normal operating mode. This will require servicing, so you will need to contact a Roland service center if this occurs.
  • We regret that we are unable to answer questions regarding the update procedure using this system program. Please perform the update responsibly, following the directions given in this document.
