If the LFO is in Sync mode, the rate will jump between the different resolutions according to the CV modulation input signal amount.Use this for controlling the envelope follower signal from an external source. The internal envelope follower signal is replaced with the CV signal that is inserted here.Use this for dynamically changing the Frequency parameter from an external audio signal. The result of this modulation is Filter FM.Use this for dynamically changing the output volume from an external audio signal. The result of this modulation is amplitude modulation (AM) of the Pulveriser output signal.
