4. Pseudo wave sequencing with the Mono/Poly’s arpeggiato­r

-

1 Now let’s try one of the most popular Mono/Poly tricks. We’ll start by turning to the Utility down and loading Default from the Initialize Program options. This is all four VCOs playing detuned sawtooth waves. Let’s turn Detune all the way down. Try a few notes to hear it. Now we’re back to a seriously bland sound. 2 Now, let’s activate the Arpeggiato­r. Switch it On and Latch it. Play a four-note chord to hear it. Now let’s tweak the VCA EG. Shut Sustain all the way off. Set Decay to 3 and Release to 2. We now have a classic sequencer sound. Now set each VCO’s oscillator to a different octave, as we did before. 3 Set the Key Assign Mode to Original. This will cause the arpeggiato­r to rotate through VCOs. That’s cool all by itself, but that’s not the best bit. Go in and select a different Waveform for each VCO. This is a rudimentar­y form of wave sequencing! Just add some delay and you’re on your way.
