D The Filter 1 output passes via the Shaper (currently not activated), on to
the Amp section, and finally to the Main Outputs.
Actually, the Amp section output is routed via the Global section before being sent
to the Main Outputs, but as currently nothing is activated in the Global section the
signal passes through unprocessed.
4. Next, click the arrow pop-up in the upper left corner of the Filter 2 slot.
A pop-up menu with the four available Filter types appears. For a description of the
filter types, see “Filter slots”.
5. Select a type of filter, e.g. a Comb filter for the Filter 2 slot.
Now that the Filter 2 slot in the Voice section is active, you can connect the oscil-
lators to it by using the lower row of routing buttons.
6. Click the routing buttons “1” and “2” to the left of the Filter 2 slot so that the
buttons are lit.
Now the two oscillators are connected to Filter 2.
7. Make sure the arrow routing button that points to the Amp section just above
the Filter 2 section is activated.
Now if you play a few notes, both oscillators are routed via both filter sections in
parallel. You could of course select to pass only one of the oscillators via one filter
and both oscillators via the other - any combination is possible.
You can also connect the Filter 1 and 2 sections serially, meaning that the output of
Filter 1 is passed through Filter 2 before reaching the Amp section. This is done as
follows:
8. Switch off the routing buttons “1” and “2” to the left of the Filter 2 slot.
If you leave them on the oscillators will pass through Filter 2 twice; both via Filter 1
and directly. This is also perfectly “allowable”, but to make things clearer in this tu-
torial we will use a standard serial filter setup.
9. Click the Arrow “left” button below the Shaper.
Now the filters are connected serially, with the output of Filter 1 (via the for now in-
active Shaper) being connected to the Filter 2 input. Both oscillators are pro-
cessed by both filters connected in series.
That concludes this tutorial on how the pre-wired connections in the Voice section
can be used, but note that you can also use the Modulation bus to make connections
- see “Modulation bus routing section”.
Other pre-defined routing assignments
There are other sections in Thor which are pre-defined and can be used without hav-
ing to make any prior assignments:
D The Amp Envelope and the Filter Envelope control the volume level and
frequency of the Filters (1 & 2), respectively.
The amount of filter envelope control is controllable by using the “Env” parameter
in each Filter section.
D The effects (Delay/Chorus) in the Global section are part of the signal
chain and can simply be switched on and used.
The Oscillator section
Oscillators generate the basic raw sound (pitch and waveform) that can in turn be
processed by the other parameters. The Oscillator section contains three open slots
which can each be loaded with one of six oscillator types. The three Oscillator slots
are numbered 1-3, with the top slot housing Oscillator 1, the middle slot Oscillator 2
and the bottom slot Oscillator 3.
