With the first patch in place, open an additional instance of your chosen synth and copy the MIDI part from the previous instance on to it. Again, set the Amplifier envelope A slider to about 1000ms to fake that pumping compression effect.
This time, however, we’ll need a Pulse waveform for Osc 1, with its width set to about 45%. Closer to 50% sounds too plain and obviously square-based, whereas much lower starts to sound too thin. In the modulation matrix, set entries for LFO1 to control the filter’s Cutoff by the maximum amount and also the Pitch by about -1.5 semitones. Activate LFO1’s tempo Sync, set the waveform to a sawtooth again, and increase the Rate to 1/16. This part will have to reach up much further with its pitch, so we’ll set the Pitchbend up range to +15, which lands on that high B (the minor 3rd interval mentioned earlier).
