Hello all!
From page 57 in the manual (1.62):
"EDIT PERFORM is actually similar to the EDIT state, with the exception that no MIDI data is transmitted when you operate on the matrix. This is particularly interesting for the Berlin School type of performances.
By default, in PAGE mode the EDIT LED button lights
green. Click on it once to toggle it to blinking orange, and
once more to make it blink green.
Again, when the EDIT LED lights steady green, everything
behaves as you know it: the step buttons toggle the step states. When
EDIT blinks orange you are in EDIT mode, and when EDIT blinks
green you are in EDIT PERFORM mode."
The EDIT PERFORM a.k.a. "Berlin School" = EDIT blinks green.
Cheers
Bo
