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 arpeggios or short melody sequences. Alternatively, it can be used purely as a modulation 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:

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 to the right of the Run button. The set mode governs how the step sequencer is played back when you press Run. The options are as follows:

Setting the direction

The Direction parameter is used to set the direction of the step sequence. The following options are available:

Programming step note pitch

To program step note pitch, you proceed as follows:

  1. Make sure that the Step Seq Trigger button is on the Controller panel is activated.
  2. Set the Run mode to “Repeat”.

    You don’t have to use Repeat mode but it makes it easier to follow the following steps.

  3. Make sure all Step buttons are activated (lit).
  4. Start the step sequencer by pressing the Run button.

    You should now hear a sequence of repeated notes, each with the same pitch (C3). The current step is indicated by a yellow LED above the upper row of knobs.

  5. Touch and swipe one of the Note knobs above one of the steps.

    A tooltip above the knob shows you the current note pitch the knob is set to, and when the sequencer repeats you should be able to hear the change in pitch for that step. Swipe upwards to raise the pitch in semitone increments. Swipe downwards to lower the pitch.

By using this general method you can continue to enter note pitch for other steps.

Inserting rests

To make step sequences more rhythmically interesting, you can program rests for steps.

Setting the number of steps

Setting the Rate

The Rate knob determines the rate of the step sequence.

Setting other values for the steps

For each step you can also program other parameters with the step value knobs below the Note knobs. Tap one of the following buttons to select what you want to edit:

The Function button

Tap the Function button to bring up a list of the following step sequencer functions:

Function Description
Shift Pattern Left/Right 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.
Randomize Notes The Randomize Notes function creates a random Note value for each of the steps.
Randomize Selected Lane The Randomize Selected Lane function creates random values for the currently selected parameter (Velocity, Gate Length, Step Duration, Curve 1 or Curve 2). The function only randomizes the selected parameter (e.g. if set to Velocity, only the velocity values are randomized, not gate lengths, step durations, etc.).
Reset Sequencer The “Reset Sequencer” function resets all step sequencer values to their defaults.
