The likely difference in language metaphors most likely introduces you into some misunderstanding, please forgive me for this. but it's still better than translating the entire branch into Russian)))
Here you can find alternative firmware for this device from Australian guys http://www.gmarts.org/tb2/ In addition to the expanded functionality for comparing with Russian, there is also a full-fledged manual in English, if you are interested, you may be curious :)
PS...
I’m familiar with the manufacturer (not personally, more virtually) after your message I talked with him, at the moment on the official website there are only eight-button controllers without an expression pedal available, next week TB6-P controllers with an expression pedal will be available, if you are interested of course
