This font is based on the 5x5 letter bitmaps used for on-screen tabs/buttons of some Roland devices. These characters were first seen on the Roland VG-8 but made their way onto later devices, like the Roland TD-10 and Roland SC-8850.

The design was very subtly tweaked on each device, so I've combined these changes into this version, which also includes an extended character set.

Enjoy :)
