| Function	| Description
Polyphony	This setting determines the number of voices that you can play simultaneously when Polyphonic mode is selected. The maximum number of voices is 32.
Release Polyphony	This governs the number of voices that are allowed to naturally decay/ring out (in the release phase of the envelope) when new notes are triggered and Polyphonic mode is selected. E.g. if you set this to “0”, any new note(s) will cut off the release of any previously triggered notes.
Mono Legato	Mono Legato mode is monophonic regardless of the Polyphony setting. It works as follows: Hold down a key and then press another key without releasing the previous. Notice that the pitch changes, but the envelopes do not start over. That is, there will be no new “attack”.
Mono Retrig	Mono Retrig is also monophonic and this mode means that when you press a key the envelopes are always retriggered.
Polyphonic	This is the standard polyphonic play mode - you can play the number of voices set with the Polyphony parameter.
Portamento On/Off/Auto	The knob is used for controlling portamento - a parameter that makes the pitch glide between the notes you play, rather than changing the pitch instantly as soon as you hit a key on your keyboard. By turning this knob you set how long it should take for the pitch to glide from one note to the next as you play them. There are three basic portamento modes: • In Auto mode, there will only be any portamento when playing more than one note. If any of the Mono modes is selected, portamento will only affect the legato notes. • When set to On, portamento is applied to all notes. • Off means no portamento.

| Mode	| Description
Band	In this mode, the Oscillator knob controls bandwidth. Turned fully clockwise, the oscillator produces pure noise. Turning the knob counter-clockwise gradually narrows the bandwidth until a pitch is produced. The pitch will track the keyboard normally if the keyboard (KBD) knob is set fully clockwise.
S/H	S/H stands for “sample and hold”, which is a type of random generator. The Oscillator knob controls the rate of the sample and hold. With high Oscillator knob settings, it produces colored noise with a slightly “phased” sound quality. With lower rate settings you can use the oscillator as a modulation source like a LFO with random values. For example, if you modulate the pitch of another oscillator using S/H with a low Rate setting as the source, you will get stepped random modulation of the pitch.
Static	As the name implies, this can generate the sound of static interference if you use low Oscillator settings. The Oscillator parameter controls Density, i.e. the amount of static. High Density settings generates noise.
Color	This produces colored noise, which is basically noise where certain frequency areas are filtered, i.e. cutting or boosting certain frequency areas in the noise. The Oscillator knob controls Color. With a maximum Color setting you get white noise, and lower settings produces noise emphasizing lower frequencies.
White	This produces pure white noise, where all frequencies have equal energy. There is no associated Oscillator parameter for White noise.

Rate	This sets the frequency or rate of the LFO.
Waveform	This sets the LFO waveform. Apart from standard waveforms (sine, square etc.) there are various different random, non-linear and stepped waveforms. The shape of the waveforms are shown in the display, and these shapes basically reflect how a signal is affected.
Delay	This introduces a delay before the LFO modulation onset after a note is played. Turn clockwise for longer delay.
KBD Follow	This determines if (or how much) the Rate parameter is affected by note pitch. If you turn the knob clockwise, the modulation rate will increase the higher up on the keyboard you play.
Key Sync	As explained previously, LFO 1 is polyphonic and will produce a separate LFO cycle for each note played. If Key Sync is off, the cycles are free running, meaning that when you play a note the modulation may start anywhere in the LFO waveform cycle. If Key Sync is on, the LFO cycles are reset for each note played.
Tempo Sync	If this is on, the Rate will be synced to the sequencer tempo.

| Parameter	| Description
Delay	This can set a delay before the onset of the envelope.
Loop	If this is activated, the envelope phase from Delay to Decay will continuously loop.
Tempo Sync	If this is on, each stage will have a length that corresponds to beat increments of the current sequencer tempo. E.g. you can have a 1/4 delay before a 1/16 attack phase followed by a 1/8 decay. Each stage can be set a range from 1/32 to 4/1 (4 bars). If this is off, the envelope times are free running and can be set in seconds (same time ranges as for the Filter Envelope).
Gate Trigger	The “Gate Trig” button can be used to switch off the envelope triggering from notes (which is the normal mode) and allow the envelope to be triggered by some other parameter. “Gate Trig” should normally be activated.

Voice Key	Voice Key lets you assign modulation according to notes. There are 4 modes selectable from the sub-menus: • Note - this is keyboard tracking. If a positive Amount value is used and the destination is filter frequency, the filter frequency will track the keyboard, i.e. increase with higher notes. • Note2 - this works similarly to Note but within a repeated octave range. E.g. if Note2 modulates Amp Pan the pan position will move from left to right within an octave range then start over. If you play chords normally over the keyboard the effect will be that notes are randomly spread across the stereo field. • Velocity - this applies modulation according to velocity (how hard or soft you strike the keys). • Gate - this is Gate on/off. E.g. if applied to oscillator pitch you will get one pitch value (set by Amount) when a key is pressed, and another value (the unmodulated pitch) when the key is released.
Osc 1/2/3	This allows you to route the audio output from the oscillators to a destination.
Filter 1/2	This is the audio output of the filters. All filter parameters affect the destination.
Shaper	This is the audio output of the Shaper module. Note that anything connected to the Shaper, e.g. Filter 1, affects the Shaper output, and thus the resulting modulation.
Amp	This is the audio output of the Amp Gain section.
LFO 1	This allows you to modulate parameters with LFO 1.
Filter Envelope	This allows you to modulate parameters with the Filter Envelope.
Amp Envelope	This allows you to modulate parameters with the Amp Envelope.
Mod Envelope	This allows you to modulate parameters with the Mod Envelope.

| Parameter	| Description
Global Envelope	This allows you to modulate parameters using the Global Envelope.
Voice Mixer	This allows you to modulate parameters using the Left and Right Mixer inputs.
Last Key	This will apply modulation according to the last note played (monophonic), either via MIDI, or from the Step Sequencer. For example, you can use Last Key to make a filter’s frequency track notes played by the Step Sequencer.
MIDI Key	This applies modulation according to notes globally, not per-voice so in other words it is monophonic. E.g. if you use MIDI Note as Source and a self-oscillating filter’s frequency as the destination, the filter will track but you will only be able to play one voice at a time. MIDI Note is handy for transposing Step patterns in real time. There are 3 modes selectable from the sub-menus: • Note - this is keyboard tracking. If a positive Amount value is used and the destination is filter frequency, the filter frequency will track the keyboard, i.e. increase with higher notes. • Velocity - this applies modulation according to velocity (how hard or soft you strike the keys). • Gate - this is Gate on/off. E.g. if applied to oscillator pitch you will get one pitch value (set by Amount) when a key is pressed, and another value (the unmodulated pitch) when the key is released.
LFO 2	This allows you to modulate parameters with LFO 2.
Performance parameters	On this sub-menu you can assign the one of the standard Performance controllers to modulate/scale parameters; Mod Wheel/Pitch Bend/Breath/AfterTouch/Expression.
Modifiers	This is where you assign parameters and functions to be controlled with the virtual 2 Rotary and 2 Button controls on the Controller panel.
Sustain Pedal	This allows you to assign the Sustain Pedal as a modulation source.
Polyphony	This allows you to apply modulation according to how many notes you play. E.g. you could have a short envelope attack when you play single notes, and a long attack when you play chords.
Step Sequencer	This allows you to apply modulation according to the settings for each step in the Step Sequencer. On the sub-menu you can chose to apply modulation according to Gate/Note/Curve 1 and 2/Gate Length/Step Duration settings for each step. In addition you have Start and End Trig, which sends a gate trigger at the start and end of the Step sequence, respectively.
CV Inputs 1-4	These are CV inputs on the back panel which facilitates the use of external modulation sources, (e.g. the Matrix) in Thor. If connected you can freely assign the external CV to any modulation destination in Thor.
Audio Inputs 1-4	These are Audio inputs on the back panel which allows you to connect external audio signals and process these using Thor parameters, or use them as modulation sources. See “About using the Audio inputs”.

| Parameter	| Description
Osc 1	There are four modulation destinations available on the Osc 1 sub-menu: • Pitch - this will affect oscillator pitch (frequency). • FM - this will frequency modulate the oscillator. The difference between Pitch and FM is that if a high frequency audio signal (i.e. an oscillator or an external audio signal) is the source, FM will not alter the basic pitch of the source, only the timbre. If Pitch is used both the pitch and the timbre will be affected. • There is also a modifier parameter, which differs depending on what oscillator type is selected. See “The Oscillator section” for details. • Osc 2 AM Amount - this will control AM modulation amount from Osc 2. See “About Amplitude Modulation (AM)”.
Osc 2/ Osc 3	Oscillator slots 2 and 3 have the same Destination parameters as Osc 1, except that there is no AM.
Filter 1/ Filter 2	The following destinations are available on the Filter 1 and 2 sub-menus: • Audio In - this allows you to connect an audio source (e.g. an oscillator or an external audio signal) to the filter input. • Frequency - this controls the filter frequency. • Frequency (FM) - this will apply filter frequency modulation. The difference between Frequency and FM is that if a high frequency audio signal (i.e. an oscillator or an external audio signal) is the source, FM will not alter the basic frequency of the source, only the timbre. If Frequency is used both the pitch and the timbre will be affected. • Resonance - this controls filter resonance. • Drive - this controls the filter’s Drive parameter. • Gender - this controls the Gender parameter (Formant filter only). • LPHPMix - this controls the LP/HP parameter (State Variable filter only).
Shaper Drive	This will control the Shaper Drive parameter.
Amp	The Amp section has three destinations on the sub-menu: • Input - this allows you to connect a source (e.g. an oscillator or an external audio signal) to the Amp input. • Gain - this controls the Amp Gain. • Pan - this controls the Pan for each voice. Modulating this parameter with for example LFO 1 means that the Pan position will modulate differently for each voice you play.
Mix	The Mixer has three destinations on the sub-menu: • Osc 1+2 Level - this controls the level of both oscillator 1 and 2. • Osc 1:2 Balance - you can modulate the level balance between oscillator 1 and 2, e.g. to sweep from one oscillator to the other. • Osc 3 Level - this controls the level of oscillator 3.
Filter Envelope	The Filter Envelope mod destinations are as follows: • Gate - this is the gate input of the envelope. A gate signal applied to this input will trigger the envelope. • Attack - this controls the Attack of the envelope. • Decay - this controls the Decay of the envelope. • Release - this controls the Release parameter.
Amp Envelope	This has the same destination parameters as the Filter Envelope.

Filter 3	The following destinations are available on the Filter 3 sub-menu: • Left/Right In - this allows you to connect a source to the filter input. • Frequency - this controls the filter frequency. • Frequency (FM) - this will apply filter frequency modulation. • Resonance - this controls filter resonance. • Drive - this controls the filter’s Drive parameter. • Gender - this controls the Gender parameter (Formant filter only). • LPHPMix - this controls the LP/HP parameter (State Variable filter only).
Chorus	The Chorus effect has the following destinations: • DryWet balance • Delay (time) • ModRate • ModAmount • Feedback
Delay	The Delay effect has the following destinations: • DryWet balance • Time • ModRate • ModAmount • Feedback
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 Sequencer 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 audio outputs and vice versa.

Randomize Sequencer Pattern	The Randomize Pattern function creates random patterns. The function only randomizes the selected Edit value (e.g. if set to Note, only the note pitch values are randomized, not velocity, gate length etc.).
Shift Pattern L/R	The Shift Pattern functions move the pattern one step to the left or right. All parameters (rests, note pitch, velocity etc.) are shifted one step.
