Setting Up The Sync Square Oscillator:
The Sync Square oscillator is actually comprised of two oscillators, a master and a slave, set
up to emulate the way sync square oscillators worked on classic analog synthesizers. To create
a program using Sync Square, select Program 1023 Editor Template. Select "none" on the
Keymap page. Select "user" on the Ampenv page for an amp envelope. 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 << soft button to change soft button pages until you see "DupLyr." Press DupLyr 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." The final step
is to go to Layer 1's DSPCTL 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. The "Syncoff" parameter, Sync Offset, is
the main parameter for shaping the tone of this sound. Syncoff sets the sync offset between
the master and slave square waves in each corresponding oscillator, which changes the shape
of the waveform output by the slave oscillator. The Sync Square oscillator is most expressive
when the Syncoff parameter is modulated during performance. Use the DSPMOD page to
assign an envelope or continuous controller like the Mod Wheel for this parameter to hear
the effect (see
