Are you interested in tonal harmony? Do you want to test your melody with harmony? MelodyHarmonizer is built for musicians, composers, and improvisers looking for new harmonic ideas. With MelodyHarmonizer, you can generate a wide variety of unique harmonizations for any melodic line you provide. Whether your input melody is tonal, chromatic, free-tonal, or even twelve-tone (dodecaphonic), the app explores what kinds of harmonic progressions can be applied to it. A Tool for Harmonic Exploration: MelodyHarmonizer is intentionally not based on standard probabilities. This means it does not necessarily produce a fully polished or the most commonly heard harmonization. Instead of forced, conventional coherence, it opens up unexpected harmonic paths and challenges your musical routine. Key Features: • Control the strength of suggested modulations. • Exclude unwanted chords from the harmonization rules. • Adjust the playback tempo of the harmonized melody. • Fine-tune relative note durations without affecting the underlying harmony. Discover tonal harmony in new contexts and expand your musical creativity with MelodyHarmonizer!

Vagabond is an idiosyncratic wavetable synthesiser, running standalone or as an AUv3 instrument in compatible hosts such as GarageBand, AUM, Loopy Pro or Cubasis. It features 16 voice polyphony, 4 unison oscillators per voice plus a sub-oscillator, switchable filter, a bit of modulation and some effects. Also built in is a MIDI processor plugin, Twelve, a generative music toy that creates 12-bar blues sequences. Vagabond uses this for demo purposes, but you can load it in other hosts if you like. It's kind of a one trick pony, but one trick is better than none. As always, Vagabond is 100% free, no IAPs, no subs, no spyware, no nag screens. We don't want your money and we don't want your data.
