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.

Ispín adds weight, warmth and grit to thin-sounding tracks. Push it gently for compression and glue, or drive it hard for full distortion. Four controls, no menus, nothing to set up. RICHNESS: Density and drive. Goes from subtle thickening to heavy saturation. COLOUR: Tilts the harmonics dark to bright, so the dirt sits where you want it. ROUGHNESS: Drives the waveform off-centre for buzz, grind and edge. OUTPUT: -18 to +6 dB of trim, for a level-matched A/B against your dry track. At zero, Ispín passes audio at unity gain — so bypass tells you what you added, not just what got louder. Six presets included: Grand So, A Bit of Dinner, The Crispy End, Hot Tea, Full Breakfast Consequences, and I Left the Immersion On. Save your own alongside them. The interface resizes to fit the space your host gives it, in portrait or landscape. Note: This is an Audio Unit Effect Plugin (AUv3), which requires a host such as AUM or Loopy Pro – or a DAW such as GarageBand, Logic Pro or Cubasis.
