Converting Pitch to Hz

A reader asks:

I was wondering if you knew of a way within Reaktor to display pitch, and other frequencies, in Hz instead of the arbitrary units that most macros use. I can’t for the life of me figure out why Native Instruments didn’t include the option to view these parameters in Hz.

Good question! Actually, they did, but it’s not an option in a checkbox somewhere – you use a P to F math module. Here’s how you’d use it:

The Numeric display module shows the frequency in Hz.

There’s a complementary module that does the opposite conversion, from Hz to the (generally speaking) 0 to 127 pitch range used by Reaktor’s primary level oscillators.
