I am a big pedal user...

2 expression pedals
One for volume
One (kronos) assignable for many things, like filter cutoff

Kronos half damper pedal, for damper..
Kronos switch for assignable button on kronos (1 or 2 depending on performance needs)

Switch on pa4x, for rotary fast/slow

Korg EC5
-asignable1
-assignable2
-start stop acomp
-var up
-var down

The big difference between the kronos and pa4x is that pedals on pa4x are a global setting
And with the kronos they can be assigned differently with every combo or program..

This makes kronos or any wotkstation much much more flexible
