Questions about Taptation tempo scale.

[psychepool]

I'm going to make a tap delay with a taptation.
I read this manual.
Http://www.thetonegod.com/tech/datasheets/taptation_pt2399.pdf

On the circuit, it can adjust the tempo scale by placing an on-off switch on pin 12
and it seems to be implementing double time by switching pin 11 to ground.

I feel bored with sharing these two things and I want to combine them with a 2P5T rotary switch.
However, there is a problem with the layout of this manual because it does not explain which scale is which.

There are three tempo scales: contact to vcc / non-contact / contact to ground.
I wonder what scale each is.
And I want to know whether the 11th pin is double time or not in contact with the ground.
