Animoog master tuning?

[Rokk]

Hi everyone, I'm new around here.
I love the Animoog, but am I missing something or it doesn't have a master tuning function? If it doesn't have it, it is a great omission and I would humbly suggest this feature for the next update. I work a lot with musicians who don't tune their instruments at 440Hz and having an adjustable master tuning is a must have for me.
Any idea?

Thank you!
Rok
