Setting Up The Sync Square Oscillator
e Sync Square oscillator is actually comprised of two oscillators, a master and a slave,
designed to emulate the way sync square oscillators work on classic analog synthesizers. To
create a program using Sync Square, select Program 2046 Editor Template. On the Program
Edit Keymap Page, set the Keymap parameter to 999 Silence. On the Program Edit Amp
Envelope Page, set the Envelope mode to User, and adjust the amplitude envelope to your
liking. On the ALG page, select Algorithm 5 at the top of the page. Use the cursor buttons
to select the function block and use the alpha wheel to select the “SYNC SQUARE (master)
>>” function. Next, press the “<MORE” soft button to change soft button pages until you
see “DUP LYR.” Press DUP LYR to duplicate the layer, creating layer 2. In layer 2, on the
ALG page, change the function block to “>> SYNC SQUARE (slave)”, and set the Alt Input
parameter to “Layer 1.” e nal step is to go to Layer 1’s DSP CTL page and turn the Level
parameter all the way down to -96dB (this ensures that you will only hear the output of the
slave oscillator on layer 2, which is the intended function of Sync Square).
Now the Sync Square oscillator should be working. e “Synco” parameter, Sync Oset, is
the main parameter for shaping the tone of this sound. Synco sets the sync oset between
the master and slave square waves in each corresponding oscillator, which changes the shape
of the waveform output by the slave oscillator. e Sync Square oscillator is most expressive
when the Synco parameter is modulated during performance. Use the DSP MOD page to
assign an envelope or continuous controller like the Mod Wheel for this parameter to hear
the eect (see The DSP Modulation (DSP MOD) Page, as well as The DSP Control (DSP
