Read full description

Bellows is a toolkit for writers who want help getting unstuck. Songs, poems, prose, or a stray idea: every tool gives you a way in, a constraint, a prompt, a fresh angle. The words stay yours. Tools: Cut-Up Technique. Slice text into fragments and recombine them into lines you would never have written straight through. The Burroughs and Bowie trick for breaking your own habits. Song Structure. Build a song one section at a time. Start from a common layout or your own, then fill in the words section by section. Freewrite. A timed, no-editing write to quiet the inner critic. Turn on No Backspace and keep moving until the timer ends. Object Writing. Write one concrete object through the seven senses to pull specific, vivid detail into your work. Constraint Game. Spark a verse under playful limits: a hand of given words to work in, plus an optional banned letter. A constraint is easier to answer than a blank page. Antonym Writing. Write the literal opposite of what you mean, then flip it back. A reliable way to find a fresher angle than the obvious one. Notebook. A fast place to catch a title, a thought, or a stray line before it slips away. Capture quickly, then file it into a notebook. The Jot an Idea widget starts a note right from your Home Screen or Lock Screen.

TraceSonic turns pictures into sound. Paint directly on a spectral canvas and hear each mark become part of a playable additive instrument: horizontal position is time, height is pitch, and brightness controls the level of each partial. Start with an empty canvas and draw with solid, soft, textured, tapered, or harmonic brushes. Fill the canvas with generated patterns, or import an image and turn its brightness into sound. Pitch snapping keeps freehand marks on your selected scale. Shape your sound with: • 128 additive oscillators spanning four octaves • Seven classic waveforms and 12 built-in wavetables • Forward, reverse, and ping-pong scanning • Adjustable pass length and tempo-synchronized loops in compatible Audio Unit hosts • MIDI note input for retuning the complete canvas • More than 60 factory patches, including tones, sequences, gestures, textures, drones, and sound effects • User patches that save the canvas and its synthesis settings • Solid, harmonic, soft, textured, and tapered brush families • Undo, redo, erasing, pitch snapping, and scale selection Use TraceSonic as a standalone instrument on iPhone, iPad, and Mac, or load its AUv3 instrument in a compatible host.
