[LFO]
The LFO stands for the Low Frequency Oscillator. The LFO waveform is used to control the pitch, level and
character of sound cyclically.
In the MFC42, the LFO is applied to the cut-off/resonance to change the character of sound cyclically. Also,
the waveform of LFO changes the way it changes the sound character.
[Envelope]
It’s the parameter that changes the pitch, level and
character of sound in time span.
In the MFC42, it is applied to the cut-off/resonance
to change the sound in time.
The A/D/S/R knobs adjust the shape of envelope.

In Envelope, it adjusts the duration between Enve-
lopes, not like the cycle length in LFO. The ADSR
knobs adjust the shape of Envelope. When Enve-
lopes overlap as the duration is set too short, the
following envelope resets the previous one.
When Envelope is triggered by the Groove Modu-
lator described later, the shape of Envelope be-
comes as shown above since the sustain time is
zero. Refer also to [ADSR] on next page.
