Processing Sequencer

The processing sequencer is located below the sonogram window. It is designed to manipulate the treatments representations, juste as in a musical sequencer. Treatments are represented in tracks as "blocks". The treatments values are edited via BPFs, which are located in the sonogram, in the waveform or instantaneous spectrum window.

This section mainly refers to the BPF edition section, which are used to create automations for a number of treatments.

BPF Edition

Adding a Treatment

Treatments Menu

To add a treatment to the signal, select an item in the Treatments menu.

Applying the Treatment

A treatment is applied to the whole signal if no selection is done.

  • To apply a treatment to a temporal segment of the signal, click and drag a selection in the channel(s) waveform window.

  • SHIFT click outside or inside the segment to increase its size. If you click inside it, this will modify the end of the segment only .

Changing the size of the segment with a click and drag.
Changing the size of the segment with a click and drag.
Waveform Windows Overview and Basic Manipulations

A treatment is applied to the global number of channels, in the case of stereo or multichannel signals.



Tracks are represented by light or dark grey bands in the sequencer window. A selected track has a blue border.

Creating/Deleting Tracks

By default, the sequencer has one empty track. When a treatment is added, a block appears in the track.

  • To create a new track, choose File/New Track or press Cmd + R.

  • To delete a track, Ctrl click inside it and select Delete Track in the contextual menu. Note that the first default track cannot be deleted.

Automatic Track Creation

If a new treatment is added in another location of the signal, it will be represented in the same track. The Create Tracks when Needed option allows to create a new track to prevent any blocks overlapping or superimposition. This option is selected by default in the Treatments menu.


Click in a track to select it, outside it to unselect it. It is not possible to select more than one track at the time.


The two small "mute" and "solo" buttons on the left of each track allow to desactivate the treatment(s) of the corresponding track, or to desactivate the treatments of the other tracks.

The sequencer isn't designed to desactivate a button if the other is on. If two buttons are on, the "mute" function will prevail.


Most basic blocks editing is done just as in a standard sequencer. Commands are also represented in the Edit menu.

  • Click on a block to select it, click outside it to unselect it.

  • Shift click on several blocks for a multiple selection. Note that multiple selection is only valid for basic move, delete, copy/paste manipulations.

  • Press Backspace to delete a block or choose Delete Treatment.

Copy, Delete, Move
  • To move a block in a track

    • select it and drag it
    • use the or keys ; add Shift to move the block faster.

    Note that the use of the grid has no effect on this manipulation.

  • To move a block to the cursor's location, cut and paste it : press Cmd + X/V or use the Cut/Paste menu items.

  • To move the block in another track, drag it manually.

Locking a Treatment

To protect the bpf of a treatment, click on the pen at the top of the editor.

You can also lock the whole treatment. A locked block cannot be moved.

  • Ctrl click in the corresponding block in the processing sequencer and select Lock. The contour of the block will get dashed.

  • To unlock it, Ctrl click and select Unlock.

Rescaling a Block in Time
  • Hover the mouse over the left or right border of block until a double triangle is displayed.

  • Click and drag the border to the desired location.

In the case of a BPF, the values will be compressed or expanded in time, but they won't change.

Note that a locked BPF can't be rescaled, whereas a protected BPF can be rescaled.

Rescaling a Treatement via the Inspector Window

A treatment cannot be trimmed from the sequencer, but when a BPF is trimmed, the result is automatically applied to the blocK.

Erasing the Content of a Track

To erase all the treatments from a track, Ctrl clik inside it and choose Erase Track Contents in the contextual menu.

Hiding/Showing/Locating BPFs

Some BPFs can be displayed either in the sonogram, in the waveform zone, or in both locations.

To choose a location, Ctrl click in the corresponding block and select a Hide/Show item

If no location is selected, the BPF will be hidden.
