Parameters
FM Depth
Range: -64 — +63
This determines the amount of modulation created by the FM function. Higher values result in greater
modulation depth.
VCO Detune
Range: -64 — +63
This determines the amount of pitch difference between VCO1 and VCO2.
VCO1 Edge
Range: -64 — +63
This determines the sharpness or smoothness of
the edge of the VCO1 waveform. Higher (positive)
values produce a sharper wave, resulting in a
harsher sound. Lower (negative) values produce a
rounder wave, resulting in a softer sound. A value
of "-64" results in a sine wave.
VCO1 PW (Pulse Width)
Range: -64 — 0 — +63
This determines the width of the VCO1 pulse wave. Higher (positive) values produce more harmonics,
resulting in a fatter sound. In general, pulse width is used to control the pulse wave; however, the
PLG150-AN can use PW with other waves as well, for a wider possible variety of sounds than usual.

This parameter differs from that in FM Synthesis (such as used by DX-series synthesizers). Too
deep of a setting will change the pitch of the voice.
Depending on the selected voice, this parameter may not be changeable ("
