Voice Parameters

1-2-5 Filter Type

LPF (Low-Pass

Filter)

This is a Filter Type that only passes signals below the Cutoff Frequency.

The sound can be brightened by raising the Cutoff Frequency of the filter.

On the other hand, the sound can be darkened by lowering the Cutoff

Frequency of the filter. You can produce a distinctive "peaky" sound by raising the Resonance to boost the signal level in the area of the Cutoff

Frequency.

This Filter Type is most popular and useful for producing classic synthesizer sounds.

LPF24D

Voice Parameters

A dynamic -24 dB/oct Low-Pass Filter with a characteristic digital sound.

Compared to the LPF24A type, this filter can produce a more pronounced

Resonance effect.

A digital dynamic Low-Pass Filter with characteristics similar to a 4-pole analog synthesizer filter.

3-pole -18 dB/oct Low-Pass Filter.

3-pole -18 dB/oct Low-Pass Filter.

This filter has a smoother cutoff slope than the LPF18 type.

A Filter Type that only passes signals above the Cutoff Frequency.

You can use the Resonance parameter to add further character to the sound.
