Using the Local Switch setting
If you’re using an external sequencer with the JUPITER-50’s keyboard 
controller section and sound generator section, you should turn the Local 
Switch OFF. Here’s why.
We need to connect these sections in the following order: the JUPITER-50’s 
keyboard 
 external sequencer   the JUPITER-50’s sound generator. 
Since the JUPITER-50’s keyboard section and sound generator section are 
connected internally, such a connection order would normally be impossible. 
However, if the Local Switch is OFF, the JUPITER-50’s keyboard section and its 
sound generator section will be independent, allowing you to use an external 
sequencer as shown here in the illustration.

setting. If you’re using a Roland pedal 
(that has no polarity switch), choose the 
“STANDARD” setting.

you can connect a damper pedal (such 
as the DP-10; sold separately) and use 
the pedal to control subtle nuances of 
the piano sounds you play.
