THOR POLYSONIC SYNTHESIZER
221
Scale parameters
The available scale parameters are the same as the Source parameters.
About using the Audio inputs
The 4 Audio inputs on the back panel can be used to connect external audio sources
and process them with Thor’s parameters.
Note that when routing audio to the Voice section, the following things apply:
• There are only mono inputs in the Voice section.
• You need to send a gate trigger for the audio signal to be heard. This can be done
in three ways; by playing notes, via notes played by the Step sequencer or from
CV gate signals.
D Routing audio to Global destinations does not require a gate trigger and
stereo inputs are provided.
D The external audio sources can also be used purely for modulation, e.g.
you can modulate an oscillators pitch with an audio signal.
This way you can use the audio input source to modulate any available destina-
tions.
Step Sequencer
Thor’s Step Sequencer is a further development of the step sequencers which were
often present in vintage analog modular systems. It can be used for programming ar-
peggios or short melody sequences. Alternatively, it can be used purely as a modula-
tion source.
You can have up to 16 steps, and each step can be programmed with various values
such as Note pitch, Velocity, Step Duration etc.
Basic operation
The main parameters and functions are as follows:
D The row of 16 buttons are used to program each step’s on or off status.
A lit button means that the step is active, and a dark button means that the step
will be a rest (silent).
D Each step button has a knob above it, which is used to set values for the
corresponding step.
D The Edit knob determines what value you set with the step knobs.
The available Edit values are Note (pitch), Velocity, Gate length, Step duration and
Curve 1 and 2.
D The Run button starts/stops the step sequencer.
What exactly happens when you press Run depends on the Run mode - see below.
Setting the Run mode
The Run mode is set with the lever beside the Run button. The set mode governs how
the step sequencer is played back when you press Run. The options are as follows:
D Repeat mode - this will repeat the sequence continuously.
Click the Run button again or use the Transport to stop.
D 1 Shot mode - this will play the sequence once then stop.
D Step mode - the Run button steps the sequencer forward one step at a
time.
D Off - the step sequencer is inactive.
Step Sequencer This allows you to control various parameters belonging to
the Step Sequencer.
• Trig - this enables control over the Step Sequencer Run
on/off status.
• Rate - this enables control over the Step Sequencer Rate.
• Transpose - this enables control over the Step Sequencer
base pitch. E.g. if you apply MIDI Note as a source to this
parameter you can transpose the sequence by playing
notes.
• Velocity - this enables control over the Step Sequencer
Velocity response.
• Gate Length - this enables control over the Step Se-
quencer Gate Length response.
CV Output 1-4 This will allow you to send signals to the CV outputs on the
back of the device. Note that you can send CV signals to au-
dio outputs and vice versa.
Audio Output 1-4 This will allow you to send signals to the audio outputs on the
back of the device. Note that you can send CV signals to au-
dio outputs and vice versa.
