Disclosure has as sub bass a Repro-1 synth patch where only the resonance is used (as you can also see in the pictures, they don’t use any of the oscilators). I tried to recreate it with the same synth, but when I recreate the patch the synth sounds out of tune because not every note matches the notes on the keyboard. How can I make sure that with this patch I can play the notes correctly all over the keyboard?
Experiment with the Filter Keyboard Amount knob. The higher it is, the more the filter cutoff frequency will change as you move up and down the keyboard. In Primer, turning it up all the way will track the keyboard pitches exactly, so that may be how the Repro works. But experiment until it sounds right.
