You can also use the parameters I laid out and change the envelope to 50% - you'll hear that it has less of an effect.

For instance, move the Attack time to 1-2 seconds - assuming the Init parameter is still set to 0 dB - what you'll hear is the filter start at the frequency you have it set to, climb up, and then once it reaches its peak, it will follow the rest of the envelope. Alternatively, you can raise the sustain percentage.įrom there, you can kind of experiment by changing one parameter at a time. If you move the filter frequency to something like 200 Hz, it will idle there. Hit and hold a note - do you hear what happened? The filter started at the high point of the envelope and filtered out the frequency over whatever length the decay time was set to and ended at the sustain, which at 0%, means it's all the way down to the frequency you set the filter out and thus basically silent. Go to the filter section and do the following:Ĥ. Turn on the filter and set it to the lowest point.ģ.

Just use one oscillator and choose something rich in frequency content, like a saw wave (Moog D one would be best).Ģ. I'm going to do my best to explain how it will work in a sort of step-by-step way:ġ. If the envelope parameter is at 0%, but you have a low-pass filter engaged at 500 Hz, that's all it will - a static filter that cuts above 500 Hz. The envelope parameter adjusts how much the filter will follow the ADSR curve.
