    I'm still relatively new to the core level of Reaktor, and I've noticed that the frequency values for any given note in the human range of hearing is between 8 and 9. This definitely doesn't mean 8-9 hz, so what does it mean? And how do we convert this into hz? I've had trouble finding one consistent scale factor that takes you from Reaktor's frequency values to more standard units, and I haven't seen anything pertaining to this in any of the manuals. Any help would be greatly appreciated!

    In Reaktor
    Frequency is Frequency. so 200Hz is 200 Hz, 10Khz is 10000Hz...
    Pitch is logarithmic with respect to frequency and is different depending on if you are using Blocks, or a traditional ensemble.
    Traditional Ensembles use midi, so 0-127 will give you similar results to midi note values from 0-127. here adding 12 is the same as doubling the frequency.
    In Blocks, the pitch ranges from 0..1. To convert this to midi equivalent, you multiply by 120. Here adding 0.1 is the same as doubling the frequency.

    Ah, so I think my problem was trying to use the Note In block as part of an ensemble, which gave me wacky and wrong values for their frequency when using the freq exponent. Thanks for the quick reply!

    Yes, the note-in block will give you an output between 0 and 1 where 0.008333.. represents a semitone step. You shouldn't need the note-in block outside of Blocks because Reaktor has built in modules to handle Midi input, and others to convert between midi note value and frequency.
