Re: SoftStep latency

You have speeds for commands that are different than the display 
responses. 
Displays are a world onto themselves.

Foot On and Foot Off are equally fast -

oh, some more questions.

What's the latency on "Foot Off" function for the Softstep?
(in one of the videos it looks quite long)

...and of course it's possible to send arbitrary command on the "Foot Off".

those questions are mission critical for edp(+related loopers) users.
