Midi Mute issue

[Echesortu]

Hello my friend.

first of all I want to say thank for this looper. look and feel is fantastic.
I am configuring a midi foot in order to control it but I am having issue with Mute function.

Midi configuration file:

• 23 127 Mute Selected
• 23 0 Mute Selected

I am able to set the mute function but then I cannot disable.

is there something I am doing wrong or could it be a program issue ? thank in advance.
