SYNC Block
The PLG150-AN features two oscillator sections: VCO 1 and VCO 2. As on conventional
analog synthesizers, the Sync block lets you synchronize the two waveforms to create a
more complex sound, with more harmonics. However, the PLG150-AN takes the sonic
possibilities even further. Since the VCO 1 oscillator itself actually contains two separate
oscillators, these two "internal" oscillators can be synchronized and then layered with
VCO 2 to produce sounds of even greater complexity. (For more about the VCOs and
Oscillator Sync, see the PLG150-AN Owner's Manual.)

• MODE
Settings: Off, VCO 1 Master > Slave (VCO 1 master into slave),
VCO 2 > 1 (VCO 2 into VCO 1)
This determines the on/off status of Sync, as well as its mode. When this is set to "VCO
1 Master > Slave," the two VCO 1 oscillators are separated inside of the VCO1 and syn-
chronized, with one designated as the controlling "master" and the other the "slave."
When this is set to "VCO 2>1," the VCO 1 is synchronized to VCO 2, with the VCO 2 des-
ignated as the "master."
• The Master oscillator determines the overall pitch of the sound, and the Slave oscillator con-
trols the tone by adding harmonics.
• SRC (Sync Pitch Control Source)
Settings: Fixed, PEG, FEG, LFO1, LFO2
The Sync Pitch Control Source setting determines the source which applies the modula-
tion over time to the slave oscillator. When this is set to "Fixed," there is no change in
modulation over time.
• DEPTH (Sync Pitch Control Depth)
Range: -64 ... +63
This determines the amount of depth of control from the Sync Control Pitch Source
(determined by the
increase the Depth. When
