OK, you mean a sweep of the sine VCO frequency or a sweep of the sine made by a filter? The latter is impossible....what do you want the filter to sweep if a sine hasn't harmonics to filter??? For a frequency sweep you can link the VCO freq to an envelope, and tweaking the envelope sensitivity offset to high levels then tweaking the ADSR segments to have the desired effect. If you want a continuous sweep you can link the VCO freq to an LFO with the previous mentioned settings....or you can make VCO freq-->LFO and LFO freq ---> Envelope and listen to the effect !!!!:wink:
