Aethron vs midi

Aethron is a minimal oscillator instrument for observing sound as waveform. Rather than a full music production app, Aethron is designed as a small sonic device for touching, layering, and reshaping oscillating sound. Add oscillators, tune frequency and amplitude, switch waveforms, invert polarity, sync phases, randomize signal states, and store the sounds you discover. Features * Multiple oscillators * SINE / SAW / TRI / SQR waveforms * Frequency and amplitude control * Fine frequency adjustment * SUM / SPLIT waveform display * RANDOM signal generation * POL +/- polarity inversion * SYNC phase reset * SOLO monitoring * STATES / STORE for saving setups * Automatic restoration of the last oscillator state Aethron is not a conventional synthesizer or a waveform viewer. It is a small instrument for touching invisible vibration through sound and waveform.

midi-sink models a tray of water with ink floating on it. Every gesture is an exact, area-preserving transformation of the whole sheet — Aubrey Jaffer's mathematical marbling — so the rings stay crisp after a thousand strokes. Two modes. MARBLE MODE is the tray under your hands: tap for a drop, drag to comb, twist two fingers for a vortex, pinch to fold, draw with the Pencil and a wake follows the tip. Plug in a MIDI instrument and it plays into the same water: an MPE controller's strike, pressure, glide and slide become drop, feed, comb and hue; a wind controller draws a single calligraphic line; any keyboard plays drops on the circle of fifths. PLAY MODE turns the iPad into an MPE instrument. A pitch lattice — chromatic grid, Jankó or piano grid — sits under your fingers; every touch is a joystick (sideways bends in semitones, push to feed ink, pull back to stir). The Apple Pencil plays legato across the keys with real force as velocity, its barrel roll deepens vibrato and the Pencil Pro's squeeze is the sustain pedal. A floating strip carries pitch, mod, two assignable wheels and sustain on the MPE master channel. The stream goes out over a virtual CoreMIDI source (also to a USB-tethered Mac), the MIDI network session and Bluetooth LE MIDI, so any DAW or synth records a standard MPE performance while the water paints it. Made for MPE controllers — ROLI Piano and Seaboard, Expressive E Osmose — the ROLI Airwave's gesture CCs, wind controllers (Roland Aerophone, Odisei Travel Sax) and classic keyboards. midi-sink makes no sound of its own: it is a visualizer and a controller.
