Zebra2 Rootkey GeoBlend?

[Etienne1973]

Hi

If I sample waveforms of another synth for Zebra2 what note/key do I have to choose?

Thanks for any help.

Best regards
Etienne

This depends on the samplerate. GeoBlend has a cycle of 128 samples. At 48000 Hz sample rate, a cycle of 128 samples yields a frequency of 375 Hz. 375 Hz is somewhere between F#4 and G4 when A4 is 440Hz.

The formula is: RootkeyHz = samplerate / 128.

So unfortunately with common sampleartes it's very difficult to "hit" 128 samples (or 64, or 512, whatever is common wavetable sizes).

But if you can tune A4 to 446Hz instead of 440Hz in your sample source, F#4 is exactly 375 Hz.
