The E330 is a high-quality digital oscillator that can be used by switching between three synthesis modes. Various controls have different roles depending on the mode.
2op FM mode: In this mode, you can apply FM to the main oscillator using the built-in modulation oscillator (modulator). MOD A controls the FM strength (index), and MOD B controls the modulator pitch. The modulator pitch is controlled as a ratio with the pitch of the main oscillator (carrier), and can be selected from 0: 1 to 7.875: 1 in 0.125 steps from 64 steps. Therefore, you can synthesize a clear FM sound while maintaining the pitch feeling.
Morph mode: Switch to the wavetable mode using 350 waveforms from the E32 wavetable. MOD A and MOD B control the output waveform of OUT 1 and OUT 2, respectively, and the transition of the waveform is smooth
Cloud mode: It outputs four detuned waveforms, like the E340's four oscillator settings. MOD A and MOD B control the detune size and chaotic behavior. A sine wave is output from OUT 4, and a sawtooth wave is output from OUT 4.
