Gliss
The ribbon synth that sings.
01 What it is
Gliss is a touch instrument for iPhone and iPad, descended from the Trautonium. Two lines of light run across the screen: slide a finger along one and the pitch follows continuously, like a voice or a bow. Press lower and the note swells; move back toward the line and it fades to a breath.
02 Gravity & flex
GRAVITY sets how hard each note pulls your finger. Set low, the lines are fretless and every pitch in between is available. Set high, you land in tune. FLEX is the elastic between finger and pitch: loose for a slow portamento, tight for a snap.
03 The voice
A Trautonium-derived engine with subharmonic dividers, vocal formants and breath noise; hold a note and an orbital vibrato settles in. 24 sounds and 28 tunings with true quarter tones, from Arabic maqam to just intonation, plus one-finger chords, an arpeggiator, a looper and a separate lane per line.
04 Free, then pro
Free forever as a real instrument: the whole gesture, three sounds and three tunings, every key and octave. A one-time PRO unlock opens all 24 sounds, all 28 tunings with Egypt–Syria shading, chords, arpeggiator, looper, lanes, tilt and effects. No subscription.
