The microKORG XL+’s sound engine uses MMT (Multiple Modeling Technology), borrowing from Korg’s well proven wealth of analog modeling technology. The MMT sound engine has been featured on numerous products, and provides two oscillators that generate huge powerful sounds.
Oscillator 1 gives you a total of seven types of oscillator algorithm to choose from, including formant waveforms such as human voice, and PCM/DWGS waveforms for vintage keyboard and strings. It also lets you use techniques that cannot be imitated on typical PCM synthesizers, such as cross modulation, unison, and VPM (Variable Phase Modulation).
By taking advantage of modulation (sync or ring) with Oscillator 2, it’s easy to create complex and powerful sounds.
