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.
