Gliss: Ribbon Synth
Glide, press, and sing
Free · In‑App Purchases
Play it like a voice: slide along two lines of light, press to swell, let gravity pull every note home. Now an AUv3 in your host, on iPad and iPhone Duo.
Gliss is a touch instrument that sings.
Two lines of light run across the screen. Slide a finger along one and the pitch follows continuously, like a voice or a bow, never stepping from key to key. Press lower on the line and the note swells; lift toward it and it fades to a breath.
GRAVITY
Each note of the scale is a well. Turn gravity down and the lines are fretless: every pitch in between is yours. Turn it up and your finger is gently pulled into tune: slide freely, land exactly. All the way up, it locks.
FLEX
The pitch follows your finger on an elastic. Loose, and it lags behind with a slow, singing portamento. Tight, and it snaps.
SOUNDS
24 sounds built around a singing core: strings, voices, winds, leads, basses, pads, plucks and a few oddities, like a cello that sings, a choir, a horn in the fog. A slow orbital vibrato settles in once the note has been held, the way a singer's does. Shape any sound with tone, texture, subharmonic mixture, formant, filter and envelope.
28 TUNINGS
Western modes, blues, Arabic maqam with true quarter tones, Turkish makam, Persian dastgah, klezmer, Southeast Asian scales, just intonation, 19 and 31 equal temperaments. Neutral intervals can be shaded from Egypt to Syria.
MORE THAN TWO FINGERS
• Chords: one finger can play a fifth, a triad, a seventh or an octave, always inside the scale
• Arpeggiator: up, down, up and back, random, locked to tempo
• Looper: record, overdub, loop, clear
• Lanes: give each line its own sound, chord and octave
• Tilt the device to bend and open the filter
• Flick a note and it slides away, bounces and fades. Touch it to catch it
IN YOUR HOST (AUv3)
Gliss is also an AUv3 instrument for AUM, Loopy Pro, GarageBand, Logic and every host that loads Audio Units. Play its two lines with your fingers inside the host, or from a keyboard, an MPE controller or a MIDI track: every note lands on a line and gravity pulls it into your tuning. Ten parameters to automate, factory presets, and the whole instrument saved with your project.
FREE, THEN PRO AND STUDIO
Gliss is free to play: the whole gesture, three sounds (VOIX, PLUIE NOIRE, KOTO LUNE) and three tunings (major, minor and maqam Rast), in the app and in your host. Two one-time purchases, each on its own: GLISS PRO for the app unlocks all 24 sounds and their settings, all 28 tunings, chords, the arpeggiator, the looper, lanes, tilt and effects. GLISS STUDIO for your host unlocks every sound and tuning in the AUv3 plugin, with MIDI and MPE in and automation. No subscription.
Designed for iPhone, iPad and iPhone Duo: landscape on a phone, any way you hold a large screen, the bars on the flat half and the settings on the raised half when it is folded. Dark, with nothing on screen that is not sound.
No account. No ads. No tracking. Gliss collects nothing; your settings stay on your device.

Gliss 1.2: in your host, on iPad, on iPhone Duo.
• AUv3: play Gliss inside AUM, Loopy Pro, GarageBand or Logic, with your fingers or from MIDI and MPE. Ten automatable parameters, the whole instrument saved with your project. The free tier plays in your host too; GLISS STUDIO unlocks the rest.
• iPad and iPhone Duo: the layout follows the window. Upright, the bars sit on top and the sheet opens below so you tune while you play. Half-folded, the bars lie on the flat half and the settings stand on the other.
• Longer pressure travel, clearer note labels, the hint only on first launch.
• SOUND and TUNING: a fixed PRO column, family headers that stay put, a mark on the current sound.
