P3: Edit-Filter Filter settings

The filter allows you to diminish or emphasize speci- fied frequency areas of the multisample selected for the oscillator. The tone of the sound will depend signifi- cantly on the filter settings.

The TRITON lets you choose between two types of fil- ter for each oscillator. Filter 1 is used for OSC1, and Fil- ter 2 is used for OSC2. If “OSC Mode” is Single or Drums, only Filter 1 will be available.

Filter EG and LFO can be used to produce time-vary- ing changes in the filter.

High pass filter

This type of filter passes the high frequency range and cuts the low frequency range. Use this when you wish to make the sound thinner. However if the cutoff fre- quency (Frequency) is raised excessively high, the vol- ume will become very low.

Resonance

When “Resonance” is set to a higher value, the over- tones in the region of the cutoff frequency will be boosted as shown in the diagram below, giving a dis- tinctive character to the sound.

Filter Type, Filter A, Filter B

Select the type of filter, and specify the “Frequency” (cutoff frequency) and “Resonance” (resonance level).

•Low Pass Resonance (24 dB/oct low pass filter with resonance): Make settings for filter A.

•Low Pass & High Pass (12 dB/oct low pass filter and 12 dB/oct high pass filter in series connection): Make low pass filter settings in filter A, and high pass filter settings in filter B.

Low pass filter

This is the most common type of filter, which passes the low frequency range and cuts the high frequency range. When the overtones of the high range are cut, a bright sound will become darker (more mellow).

24 dB/oct and 12 dB/oct refer to the steepness of the cut. 24 dB/oct means that the gain will decrease 24 dB in one octave (i.e., as the frequency doubles). A 12 dB/ oct filter would decrease the gain 12 dB in one octave. The 24 dB/oct filter produces a steeper cut.

Filter 1 Mod. tab

Controllers and the filter EG can be used to modulate the filter cutoff frequency that was specified in the Fil- ter 1 tab. By using a controller to vary the tone or by using an EG to create time-varying changes, you can add a rich variety of tonal change to the sound.

Keyboard Track

This varies the cutoff frequency according to the key- board location that you play.

•When “Ramp Low” is set to a positive (+) value, the cutoff frequency will rise as you play lower on the keyboard, making the sound brighter. When set to a negative (–) value, the cutoff frequency will fall as you play lower on the keyboard, making the sound darker.

•When “Ramp High” is set to a positive (+) value, the cutoff frequency will rise as you play higher on the keyboard, making the sound brighter. When set to a negative (–) value, the cutoff frequency will fall as you play higher on the keyboard, making the sound darker.
