Hello.

Can someone explain what R. Base is?
Chord seems to tie in with this also.

If I have the APC ON but no rhythm is playing, and LEFT is OFF. I can hear the R. Base and the Chord Sound when I hold down a chord on the left split side. I can change these sounds going to the SOUND> PART SETTING and scroll to the very end, or use MIXER.

When the rhythm is playing these sounds cancel out and the APC setting takes over... Kinda confused on what the concept is and when to use it.
