Selecting Chop and Ratchet for config. Binary patterns

Hi,

on page 29 of the manual it says:

"... Configuring Binary patterns - in SET-mode select either Velocity, Delay, Chop or Ratchet parameter using the buttons..."

My question:

How do I select Chop or Ratchet, as there are no buttons for these both?

I tried things like double-tapping the Velocity and Delay-buttons, holding them longer - no succuss.

I was not able to select Chop or Ratched.

How do I do this?
