This prototype is actually unipolar, 0 - 1
Apple click the disk icon next to the wavetable input to see the positive loaded waveform.
Load in the Sine from the Kyma/Waves/Waveforms for a traditional (how an analogue LFO would range) bipolar (-1 0 +1)
You can save this modified sound to your Frequently Used Sounds.kym and then select this as a custom prototype so your newly modified module appears in the prototype list. (P302 of the KymaXRev)
