I think it would be really cool if the Remote could do this.
The idea is you step on a button to activate the FX, release the button to turn off the effect, as opposed to stomp once for on and once for off.
This could be incredibly handy if you want to say activate a harmonizer mid way through a solo and then release the button to turn it off.
Just seems more intuitive than stomping a button once for on and then again for off.
This seems doable, given that the looper works by holding down the button for record and then releasing it to trigger playback.
Should clarify that I don't own a Remote, but reading the manual, it didn't seem possible with FX.
