      Why won't the LFO modulate the frequency of the pitchshifter in this preset?

      Why has the LFO got audiotypeoutputs and not controltypeoutputs? (BTW: what is the range of an audiotypesignal?)

      Thanks, Ole

      Looks like you tried to modulate the +/- 4800 mod input with +/- 1 signal.

      Thanks, you're right. Now it's better. Using a controlsignal works, but the updating will only be 100Hz.  So this will be a trick for modulating modules with only controlinputs and no modinputs.

      Nickrose, where are you?:-)

      Why has the LFO got audiotypeoutputs and not controltypeoutputs?

      Control signals run at an unspecified rate, but usually 100Hz or faster. Because of this, one cannot build a meaningful oscillator with control outputs as its frequency would be entirely unpredictable. Thus, the LFO has a mod type output. This runs at a quarter of the sample rate.

      Connecting an LFO to an A_TO_C is reasonable, as the LFO will maintain a constant frequency, but its update rate will be variable. Essentially, using control signals as modulators is "iffy."

      The frequency inputs of the REVERSE is control type, presumably because the designers figured that fast modulation would not be useful. A PITCHSHIFT modules does have a mod type frequency input.
