ting of 0, the pitch EG times will be just as specified by the “Attack/Decay/Release Time” settings.

The alternate modulation value at the moment that the EG reaches each point will determine the actual value of the EG time that comes next.

For example, the decay time will be determined by the alter- nate modulation value at the moment that the attack level is reached.

When this parameter is set to values of 16, 33, 49, 66, 82, or 99, the specified EG times will speed up as much as 2, 4, 8, 16, 32, or 64 times respectively (or slowed down to 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64 of the original time).

For example if “AMS” is set to Velocity, increasing the abso- lute value of “Intensity” will allow strongly-played notes to increase the changes in pitch EG “Time” values. The direc- tion of the change is specified by “Attack Time Swing” and “Decay Time Swing”. As you play more softly, the pitch EG times will more closely approach the actual settings of the pitch EG.

-99…+99 Parameter value.

Attack Time Swing

This parameter specifies the direction in which “AMS” will affect the “Attack Time” parameter. With positive (+) values of “Intensity”, a setting of + will cause the time to be length- ened, and a setting of – will cause the time to be shortened. With a setting of 0 there will be no change.

Decay Time Swing

Specify the direction in which “AMS” will affect the “Decay Time”. With positive (+) values of “Intensity”, a setting of + will cause the time to be lengthened, and a setting of – will cause the time to be shortened. With a setting of 0 there will be no change.

Here you can make settings for the filters that will be used by the oscillators. You can select either a 24 dB/octave low pass filter with resonance, or a series connection of a 12 dB/octave low pass filter and a 12 dB/octave high pass filter.

Filter		Osc1
Selected:		Osc1
Type:	LPF Resonant
Trim:		99
Frequency A:		7

Selected

Use this parameter to select an oscillator to put in edit. Alter- natively, you can select oscillators using the F1-F4 buttons.

Filter Type

This parameter selects the type of filter (Low Pass Resonant, Low Pass & High Pass) for the selected oscillator. When the Low Pass & High Pass filter type is selected, the filter B will be activated.

Low Pass Resonance: 24 dB/octave low

pass filter with resonance

Low Pass & High Pass: 12 dB/octave

low pass filter and 12 dB/octave high pass filter in series

Trim

Use this parameter to adjust the level at which the audio sig- nal output from the selected oscillator is input to filter A. Note: If this value is raised, the sound may distort if Resonance is set to a high value or when you play a chord.

00…99 Trim level.

Frequency A (Cutoff Frequency A)

This parameter specifies the cutoff frequency of filter A.

This is a filter that cuts the high-

	Low Pass		frequency region above the cutoff
Level			frequency.
			This is the most common type of filter,
	12dB/oct		and is used to cut part of the overtone
	24dB/oct		components, making an originally bright
			timbre sound more mellow (darker).
			When the “Filter Type” is Low Pass
		Frequency	Resonance, the cutoff will have a
			steeper slope.

00…99 Cutoff frequency value.

Resonance A

The resonance emphasizes the overtone components that lie in the region of the cutoff frequency specified by “Frequency”, producing a more distinctive sound. Increasing this value will produce a stronger effect.
