Controller Bar Fonts

I’m sharing some recently-developed resources that help with an over-crowded Controller Bar. There is an attached package containing 30 fonts in 5 widths (Normal through Ultra-Narrow) and 3 weights (Normal, Semi-Bold, Bold). I am also including my Theme files as an example of how to set up a custom Cantabile theme.

The related post is:

After Brad assisted with the issues in that post, I was able to forge ahead and build fonts and themes that work nicely for my crowded Controller Bar setup.


I currently have themes for three Controller Bar layouts on two different hosts: Husky, a desktop with 3840 pixel wide screens and Atlas, a performance laptop with 1920 pixel wide screens.

The one Husky layout looks like this:

  • Titles: 17pt Kurinto Sans Core Nar (Narrow)
  • Button text: 24pt Kurinto Sans Core ENar SmBd (Extra-Narrow Semi-Bold)

The two Atlas (laptop) layouts have different amounts of info and use different fonts:

  • Titles: 13pt Kurinto Sans Core Nar (Narrow)
  • Button text: 18pt Kurinto Sans Core Nar SmBd (Narrow Semi-Bold)

  • Titles: 16pt Kurinto Sans Core Nar (Narrow)
  • Button text: 22pt Kurinto Sans Core ENar SmBd (Extra-Narrow Semi-Bold)

The Fonts

The set of fonts is from my font project that I distribute under the OFL 1.1 open-source license. Here’s a snapshot of the fonts in the ZIP package:

These fonts are carefully designed to be readable on screen at relatively small sizes and compressed widths.

Note that I am using the Figure Dash character (Unicode U+2012) rather than the default ASCII Hyphen-Minus (U+002D). Figure Dash is much wider and somewhat higher, to line up properly with digits (the Hyphen-Minus has to work with lower case letters and it much lower). Another possibility would be the dedicated Minus Sign (U+2212). However, the Figure Dash does take up some horizontal real estate.

The Italic fonts are really slanted (Oblique) versions of the upright fonts – a general design principle throughout the Kurinto fonts.

At this point, I am tending towards the Semi-Bold weight for the data on the Controller Bar … it seems a good balance between visibility and not getting “clogged up” on-screen.


Each of the themes included in the ZIP package contains a single main.gtl text file that can be edited. Each of those files has examples of how to access all the fonts included in the ZIP package.

Some things to note:

  • Fonts will need to be installed on your system to work. C4 is not (yet) able to load font files on the fly from the theme package or resource directory.

  • I am currently unable to load a theme from my local Resources folder (the one declared in Options -> File Locations -> Resource Folder). The Theme does appear in the selection list, but then when it is selected, Cantabile cannot find the Theme. This appears to be a bug as of v4062, reported here:
    Controller Visual Feedback
    I’ve solved this issue by establishing a Junction from the Cantabile install location (typically /Program Files/Topten Software/ Cantabile 4.0) into my Resource folder for each of the themes (a bit messy, but it works for now).

  • Due to arcane font naming issues, the naming of the fonts is a bit funky. Semi-Bold fonts are named somewhat differently than the Normal and Bold weight fonts. Use the examples in the main.gtl files as guidelines. (3.5 MB)


This is Great Clint!! Thanks so much for your contributions. Very readable for such dense grouping :+1:


By the way, I’ve just made the first post in this discussion into a Wiki, so feel free to update it with any info or issues you encounter regarding using these fonts on the Controller Bar.

For info on editing a Wiki on this Discourse forum, see:

Hi Clint.

I tried them out and as advertised the set created more room on the Controller Bar on my busier Ctrl Bar versions. Thanks again for this!
