Graphical MIDI Tools 2024.2 for Sibelius adds tempo editing


Graphical MIDI Tools (GMT), the ingenious plug-in for Sibelius by Santiago Barx that allows the user to manipulate MIDI information in the score in a graphical manner, has received a significant update to version 2024.2. This update adds a graphical tempo module directly to the GMT interface, making it easier to interact with GMT directly in the Sibelius environment.

The Graphical Tempo Module

The tempo track is unveiled by clicking on the Tempo tab in the top left of the GMT interface.

Draw the tempo curve graphically

Similar to a DAW, you can draw in ritardandos, accelerandos, or other tempo inflections into a Sibelius score, for a more realistic/human-like playback of your score.

As usual, GMT writes invisible instructions into the Sibelius file that correspond to the curve that is drawn in the GMT window.

Editing options

Several editing options are available to the left of the tempo track. The first two will be familiar to anyone who has used a DAW.

You can set up a snap grid for node alignment…

…and choose the node type (jump or ramp).

There is also another option here: “chomp” mode. Yum!

Chomp mode

In standard (traditional) mode, adding a node makes the curve keep its value until the end of the score. But the chomp mode allows you to draw the curve and constrain those edits to the mouse dragging range.

It’s like if you were “biting” a piece of the curve.

This is useful, for example, to incorporate small ritardandos at the end of a measure or phrase.

Zoom in and out using the Pendulum Control

It’s possible to easily zoom the tempo lane vertically by setting the visible BPM range through GMT’s pendulum control.

The pendulum, inspired by old metronome sticks, has two weights. Drag the upper or lower one to set the BPM viewing limits.

Enlarge the tempo lane with the Size Lever Control

You can resize the tempo lane for working in more detail with the size lever, which has three positions for small, medium or full window size.

Override written indications

If there is a written tempo indication in the score, GMT displays it in a text box. You can override its behavior by drawing over it.

To revert to the original effect, click on the text box. GMT will restore its original behavior.
