The task that's taking you too long in Sibelius?
It shouldn't.

If you've used Sibelius professionally for any length of time, there's probably one task you've quietly accepted as "taking forever."

Maybe it's inserting custom symbols or markings, chord diagrams, or a layout and playback feature Sibelius simply doesn't support natively.

Whatever it is, you've probably worked around it so many times that it feels normal.

It doesn't have to be.

INTRODUCING THE CUSTOM TOOL PROGRAM

Through the Custom Tool program, you get a notation tool built specifically for your workflow — most projects are completed in under three weeks.

Tell me what you're struggling with below, and I'll tell you exactly what's possible.

"IF ONLY I HAD A BUTTON FOR THAT..."

Notation software is built for everyone, which means it's rarely built for you. The features that would really elevate your work — your workflow, your notation style — often just aren't there.

A custom tool closes that gap. Boost your creativity and produce more original sheet music with features built around exactly how you work.

YOUR MUSIC. YOUR TOOLS.

Whether you're a composer, music editor, or educator, you can get tools built specifically around your workflow — not the other way around.

A few things past clients have built:

  • Custom symbol and marking tools for personal or house notation style
  • Custom toolbars and menus tailored to a specific workflow
  • Automated proofreading and review, cutting repetitive checks down to seconds
  • Fast notation for glissandos, articulations, and other recurring gestures
  • ...and more, depending on what's slowing you down

POWERED BY GMT — TRUSTED BY HUNDREDS OF COMPOSERS WORLDWIDE

Every custom tool is built on Graphical MIDI Tools — the MIDI editor extension for Sibelius already used by hundreds of composers worldwide.

That foundation means:

  • Fully customized interfaces, built around how you actually work
  • Flexible interaction — mouse, keyboard, or other input devices
  • Closed-source delivery, so your custom tool and workflow stay protected
