The Waver Toolbar

The Waver Toolbar can be found at the top of the KRISTAL Waver window, and contains the following controls:

  Load/Save Arrangement

The Load and Save buttons can be used to load and save KRISTAL Waver Arrangement files (*.waver).

Arrangement files are different from the Project files (*.kristal) saved from the Mixer window (or from the main application window, if you have the KRISTAL desktop activated). While Project files contain a complete record of your work, including mixer settings and Plug-In parameters, Arrangement files contain only settings relevant to the KRISTAL Waver window, e.g. the names of the project's audio files, their relative positions on the timeline, etc.

Additionally, KRISTAL Waver can export the arrangement to AES 31 ADL files (*.adl).

AES 31 is an 'industry standard' developed by Audio Engineering Society (AES) for the exchange of edit data between DAWs (Digitial Audio Workstations). This could be useful if you want to transfer your songs to a professional recording studio for further mixing or post-production.
For more information on AES 31, see

  Edit History

The Edit History button opens the Edit History dialog, which can be used to re-trace your steps back through a list of the changes made in the course of the session.

The Edit History dialog shows a list of recent edits, each with a more or less descriptive name, e.g. Edit Volume @ 'drumloop' or Cut part 'Bass line chorus'.

To return to an earlier state, just click on the name of the edit you want to revert to; it's name will be underlined in red, and you'll see the KRISTAL Waver window update accordingly.

Once you've found the edit you want to revert to, click the 'Close' button to return the main KRISTAL Waver window.

The Edit History list can also be accessed by right-clicking in the Arrangement and choosing 'Edit History' in the context menu that appears. The most recent edit can be undone by choosing 'Undo:' in the same menu.

  Waver Pool

Clicking the 'Pool' button opens the Waver Pool dialog, which displays a list of the audio files used in the current project. Click on a filename, and a summary of the file's properties is displayed at the top of the dialog.

  • If a file can't be found (for example, if it's been deleted or moved) its name will be 'greyed-out' in the list. If you know where a missing file has been moved to, you can tell KRISTAL by clicking the 'Locate Missing...' button and navigating to the file's location in the dialog that appears.

  • Recorded (or Bounced) files are displayed in red.

  Select, Cut and Glue

Select, Cut and Glue are three different cursor tools available in KRISTAL Waver.

Select is the default, and it resembles an ordinary mouse pointer 'arrow'. You can use the Select tool to move audio parts around in the Arrangement, edit volume envelopes and so on.

Using the Select tool in conjunction with the 'Alt', 'Ctrl' and 'Shift' keys, alters its behaviour in several useful ways. We'll see examples of this when we look in more detail at working with audio parts.

The Cut tool is activated by clicking the 'Scissors'. The mouse pointer changes to a smaller arrow icon, with a floating 'hint' beside it showing the current pointer position, expressed in whatever the chosen time units are (for more information about time units, see The Waver Arrangement).

Clicking on an audio part with the Cut tool causes it to be split in two at the point where you clicked. The two halves can then be treated as separate parts, moved to different tracks, etc.

The Glue tool is more or less the opposite of the Cut tool, i.e. it joins two separate parts together to create a new one. First select the Glue tool, then click on the first of the two parts you want to join together, then click on the second. A special kind of 'Folder part' is automatically created in the track, containing the two chosen parts, and any empty space between them required to maintain their relative positions.

Note: only audio parts on the same track can be Glued together.

Clicking on an audio parts within a selected Folder part, causes the part to be separated and removed from the Folder, effectively undoing the Glueing process.

  Zoom In/Out

The Zoom In and Out buttons provide a simple way to enlarge or reduce the size (width) of the audio parts displayed in the arrangement.

It's also possible to use keyboard shortcuts to Zoom In and Out. You can Zoom In by pressing 'H' or 'Ctrl' and '+'. You can Zoom Out by pressing 'G' or 'Ctrl' and '-'. In addition, clicking and dragging on the blue rectangle in the strip above the timeline ruler allows you to Zoom In or Out dynamically, as required.


When Autoscroll is activated, the arrangement window will automatically re-draw during playback and recording, so that the song position marker is always visible on screen.

When Autoscroll is not activated, the song position marker will run off the edge of the screen when it reaches the end of the visible portion of the arrangement.

Playback and recording are unaffected, regardless of whether Autoscroll is on or off.

  Snap, and Snap Preset menu

The Snap option can be used to make editing and arranging in the KRISTAL Waver window easier.

When Snap is activated, it's as if an invisible 'grid' has been super-imposed over the Arrangement.

Any audio parts moved using the Select tool will automatically adjust their positions when released to 'Snap' to the nearest grid line. You can change the 'resolution' of the Snap grid by choosing a new value in the 'Snap to Grid' drop-down menu.

By default, the Snap grid is calibrated in 'Seconds'. You can change this by right-clicking on the ruler along the top of the Arrangement, and choosing 'Samples' or 'Bars+Beats' from the context menu that appears. 'Bars+Beats' will probably be the most useful setting when you're arranging a song, since it allows you to ensure that your different takes can be edited to play perfectly in time with one another.

  Timebase Linear/Musical

Clicking this button toggles the Timebase of all tracks between 'Linear' (default) and 'Musical'.
