Tuning of Triton Taktile to 44x Hz

[Chilli..]

Hello Musicians,

I use Triton Taktile in our Band for a couple of songs when second keyboard is needed. As we are to play an open air now and have some brass players also, we might have to adjust tuning to 443 or even 444 Hz as brass won't reach 440Hz in bare sun anymore.

Does anybody know, how to adjust the tuning????

Best regards and a nice Weekend!
