432Hz? Is it possible

Is it possible to lower the output to 432Hz in the program settings?

In the advanced settings, there’s a tuning section, where you can load new tuning files or change the root pitch. I think the usual way people switch to 432 Hz tuning is simply by lowering the master tuning by 32 cents. You can adjust the tuning a bit finer than just cents in Vital, so if you want, you can try to get closer to:

1200*log2 (432/440) = -31.7666 cents
