So I should select always StrEns?
Hi rock123456789,
simply select the channel that plays the Chords you need (usually a channel with Strings chords, Rhythm Guitar chords, Piano chords etc.). You can also select more than one channel. If desired, you can also (additionally) define the Bass channel (set the checkmark in the second column of checkboxes in this case).
P.S.
Please read also the section "Compute Chords" in the PSRUTI Manual, page 15. (Click on "Help" button to open the Manual.)
Best regards,
Chris
