Moving Dualchord to another Track

[DesignBureau]

Assign the new track 8 first.
Then mark  (SHIFT + MARK) the rows in the column for track 6, and pressw SHIFT+MARK again.
On track 8, you press SHIFT+COPY and the patterns are copied to Track 8.

You can remove the patterns from the sequencer screen of track 6. This can be done in the same way with mark and SHIFT+Delete. Or assiging to another tracktype will delete the patterns from the sequencer screen as well.

Worked perfectly
(that's what I thought I just did not dare)
thanks
