Sweet MIDI Harmony Maker

If you have a MIDI keyboard or other MIDI-compatible device connected to your computer and wish to make tweaks to the sound, you can resort to Sweet MIDI Harmony Maker. Available as a free-to-use application, it comes wrapped in a user-friendly interface with intuitive options for enhancing MIDI keys.

Installing it isn't difficult either, thanks to a no-fuss setup wizard. As far as the GUI goes, the main application window shows three distinct areas for picking three different MIDI channels and making adjustments for each.

To get started, you can choose the MIDI input and output devices. The harmony type can be selected from minor melodic, minor harmonic, wholetone, whole/halftone, chromatic, major pentatonic, minor pentatonic, and minor 6 pentatonic.

You can pick the derivation type and scale, skip or correct non-harmonics, as well as set the harmony step and velocity. When it comes to viewing options provided by Sweet MIDI Harmony Maker, you can ask the tool to display only one or two areas instead of three (for the MIDI channels), and make the window stay on top of any other running programs.

A wide range of instruments can be picked from various categories, such as piano, chromatic percussion, organ, guitar, bass, strings, ensemble, brass, pipe, synth or sound effects.

All settings can be saved to file in order to later open it and pick up where you left off. It's possible to create multiple profiles this way, each with unique MIDI configurations for various instruments.

Unfortunately, the tool hasn't received updates for a long time and we're not sure if it's still in development. However, it worked smoothly on Windows 10 in our tests, without any compatibility issues.

All aspects considered, Sweet MIDI Harmony Maker offers a clear-cut interface and options for helping you enhance the harmonics of your MIDI device with ease.
