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 2.1. This update, which is free for existing GMT 2 customers, adds a transport bar directly to the GMT interface. It also adds several new editing and navigation features, to make it easier to interact with GMT directly in the Sibelius environment.

What’s new in GMT 2.1
Transport
GMT now includes a transport bar, featuring a Play button and two displays to see the current playback position:
- The first display shows the current bar/beat/MIDI tick.
- The second shows the current time in hours/minutes/seconds.
This is very handy when scoring to picture. You can optionally show the Sibelius transport window at the same time:
Toolbar for piano roll
The note editing tools are now conveniently grouped on a toolbar above the piano roll. Now you will find the pointer tool (to edit a note’s sound duration or position) and the “phantom” notes tool, directly underneath the CC controller tabs. Don’t be scared!
Snap-to grid
Now you can edit the sound duration of written notes or insert phantom notes using a snapping grid.
You can select the grid resolution from the pull-down above the piano roll, or turn it off.
Edit node properties panel
One of GMT’s most impressive features is the ability to draw automation curves.
In GMT 2.1, from within the MIDI CC automation curve lane, you can now edit a node’s value manually or specify whether is a jump or ramp. Click on the node’s value-label to open the Edit Node panel. When you are done, press Enter and the node will be saved with the new properties.
Select and edit notes over multiple tracks
It is now possible to select and edit or erase notes among different tracks, for more similarity to a DAW-like workflow.
New mouse wheel functionality
A long-requested feature, there are new shortcuts to control the piano roll zoom and scroll:
- Mouse wheel: Scroll vertically.
- Mouse wheel + Shift: Scroll horizontally.
- Mouse wheel + Control: Zoom horizontally.

Santiago is, and remains, da boss.
Very Helpful Improvements! Especially the snap and multi-track editing.
