The Controller panel contains the Keyboard Modes and Note Trigger section, four virtual (freely assignable) controls, Pitch Bend Range selector and Master Volume knob.
The Keyboard Modes section
In this section you make basic keyboard related settings for a patch. It has the following options:
| 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 also depends on the specs of your iPad. |
| 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:
|
| 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:

The Trigger section
Using the buttons in this section you can select in what way Thor will respond:
- Via note input only.
- Via the Step Sequencer only (see “Step Sequencer”).
- Or both.
The section also has a Note On LED indicator.
About the assignable controls
- The rotary knobs and buttons on the Controller panel are assignable controls that can be assigned to multiple parameters and functions in Thor.
- You assign parameters to the knobs and buttons on the Modulation Bus panel (these are located on the “Modifiers” sub-menu - see “Modulation Bus routing section”).
- Each control can be assigned to several parameters.
- Tapping on the label for a Rotary or Button lets you type in an appropriate name for it.
About the button key note function
To the right of the two assignable buttons there are corresponding displays. These can be used to assign a key for turning the button on momentarily, as long as the key is depressed.
- Tap in the display and swipe up or down to assign a key for the button status.
The assigned key will now turn the function(s) assigned to the button on for as long the key is held down.
- Note that the key note function can only switch from off to on, not the other way around, so make sure the button is deactivated if you wish to use this function.
An assigned key will not trigger a note, only the button status. Also note that the button will not light up when you press the assigned key.
The Pitch Bend Range parameter
- The Pitch Bend Range parameter sets the range of the Pitch Bend action.
For example, “7” means +/-7 semitones.
Range: +/-24 semitones (+/-2 octaves)
- Pitch Bend is hard-wired to the pitch parameter of the three oscillators, but you can of course use it to control any parameter you like. If you don’t want Pitch Bend to affect oscillator pitch, simply set the Pitch Bend Range parameter to “0”.
Master Volume
This is the main output volume control for Thor.
