THOR POLYSONIC SYNTHESIZER

About Oscillator Sync

Oscillator sync is when one oscillator will restart the period of another oscillator, so

that they will have the same base frequency. If you change or modulate the frequency

of the synced oscillator you get the characteristic sound associated with oscillator

sync.

A synced oscillator that resets the other oscillator(s) is called the master, and any

synced oscillator that is reset by an other oscillator is called a slave. In Thor, oscillator

1 is the master, i.e. this controls the base pitch of the oscillators, and oscillators 2 and

3 are slaves.

D You switch Oscillator sync on or off by activating the Sync buttons to the

left of Oscillator slots 2 and 3.

D The Sync “BW” sliders to the left of Oscillator slots 2 and 3 allows you to

adjust the sync bandwidth.

This allows you to change the character of the oscillator sync. The parameter basi-

cally sets how abrupt the reset is - high bandwidth settings produces a more pro-

nounced sync effect and vice versa. The picture above illustrates high bandwidth

reset - if lower bandwidth settings are used the slave osc curve will be more

rounded at the reset points.

About Amplitude Modulation (AM)

AM (Amplitude Modulation) is often referred to as ring modulation. AM works by mul-

tiplying two signals together.

D In Thor, Oscillator 2 amplitude modulates Oscillator 1.

The Ring Modulated output will then contain added frequencies which are gener-

ated by the sum of, and the difference between the two signals. This can be used

for creating complex, enharmonic sounds.

D The amount of AM is set using the slider to the left of the Oscillator 1

slot.

Mix section

The Mix section allows you to adjust the levels and the relative balance of the three os-

cillators.

D The two sliders controls the output levels of oscillators 1-2 and oscillator

3, respectively.

D The Balance knob sets the balance between oscillator 1 and 2.

The Balance parameter is also a modulation destination, allowing you to modulate

the balance of the two oscillators with e.g. an LFO. Note that the oscillators have

to be connected to the filter(s) via the numbered routing buttons for the Mix sec-

tion settings to have any effect.
