These parameters specify how “AMS2 (Time Mod. AMS2)” will control the amp 1 EG “Time” parameters (☞ “AMS1 (Time Mod. AMS1)”–“R(AMS1 SW Release)”).

PROG 5.3: Ed–LFOs

Here you can make settings for the LFO that can be used to cyclically modulate the Pitch, Filter, and Amp of oscillators 1 and 2. There are two LFO units for each oscillator. By setting the LFO1 or LFO2 Intensity to a negative (–) value for Pitch, Filter, or Amp, you can invert the LFO waveform.

5.3–1: OS1LFO1 (OSC1 LFO1)

Indicates settings for the “OSC1 LFO1,” which is the first LFO that can be used for oscillator 1.

5.3–1a: OSC1 LFO1

Waveform [Triangle 0…Random6 (Vect.)]

Selects the LFO waveform.

The numbers that appear at the right of some of the LFO waveforms indicate the phase at which the waveform will begin.

■5.1–3d: UTILITY

☞“Write Program” (1.1–1c), “Copy Oscillator,” “Swap Oscillator” (2.1–1d)

For details on how to select the desired utility function, refer to “PROG 1.1–1c: UTILITY.”

Sync Both EGs

If you select “Sync Both EGs” from the Utility menu and press the [F8] key, a check mark will appear at the left of “Sync Both EGs.” In this state, the amp 1 EG and the amp 2 EG can be edited simultaneously. (Editing either one will

Random1 (S/H):

Conventional sample & hold (S/H) in which the level changes randomly at fixed intervals of time

Random2 (S/H):

Both the levels and the time intervals will change randomly.

Random3 (S/H):

The maximum level and minimum level will alternate at random intervals of time (i.e., a square wave with random period).

These types cause Random 1–3 to change smoothly. They can be used to simulate the instability of acoustic instruments etc.

Frequency [00…99]

Sets the LFO frequency. A setting of 99 is the fastest.

PROG 5.2: Ed–Amp2

Indicates settings for amp 2 which controls the volume of oscillator 2. Pan settings are also made here.

5.2–1: Lvl/Pan (Level/Pan)

5.2–2: Mod. (Amp2 Modulation)

5.2–3: EG (Amp2 EG)

These will appear when “Mode (Oscillator Mode)” (2.1–1a) is Double. (☞ “5.1: Ed–Amp1”)

Ofs (Offset) [–99…+99]

Specifies the central value of the LFO waveform.

For example, with a setting of 0 as shown in the following diagram, the vibrato that is applied will be centered on the note-on pitch. With a setting of +99, the vibrato will only raise the pitch above the note-on pitch, in the way in which vibrato is applied on a guitar.

When “Waveform” is set to Guitar, the modulation will occur only in the positive (+) direction even if you set “Off- set” to 0.

Offset settings and pitch change produced by vibrato

Pitch offset = –99 offset = 0 offset = +99
