Hello all, Smee again, fiddling with VCF modulation. Looking at parameters, I can see the VCF Modulation Group making use of two arbitrary LFOs. There is also a Resonance Modulation Group, again using an LFO. Does the VCF Modulation Group mean the filter's cut off control? and how does using 2 LFOs work for that? Regards Tim

Yes, VCF modulation group is for filter cut off. Here's an example of using two LFO's with VCF cutoff. Set up a patch as follows: P1-41 to 20. VCF cut off set low. P2-11 to 0. LFO1 slow. P2-12 to 0. No delay on LFO1. P2-13 to 1. LFO1 free running. P2-21 to 8. LFO2 medium speed. P2-12 to 0. No delay on LFO2. P2-13 to 1. LFO2 free running. P2-41 to 3. right hand sawtooth waveform P2-42 to 1. use LFO1 P2-43 to 4. modulation level P2-44 to 1. triangle waveform P2-45 to 2. use LFO2 P2-46 to 3. modulation level Now you will hear LFO1 (in sawtooth) slowly go from low to high VCF. But LFO2 will insert a small VCF "warble" as it also modules VCF faster. Enjoy! Mike ________________________________
