HollowTone

Generate evolving atmospheric audio textures through a procedural instrument.

Our take

Good for musicians exploring ambient sound design

Realtime layers, nine macro parameters and randomization support quick exploration.

Keep in mind: It is not a conventional sample player or a complete arranging workstation; host integration depends on compatibility.
