Glisslo - Retro Synth

Glisslo turns your iPhone into a pocket-sized retro touch-slide synthesizer. Drag your finger across the touch strip to glide smoothly between notes, or tap for precise pitches - then shape the sound with vibrato, filters, switchable waveforms, and effects. Lay down a drum loop, record your performance, and share it - all on-device, completely free, with no account and no internet required. FEATURES • Touch-slide keyboard - glide between notes with glissando-style playing, or tap keys for fixed pitches, with a two-row layout for semitone precision • Switchable key labels - display the keyboard as numbers (1,2,3,4) or note letters (C,D,E,F), whichever you prefer • Octave shift - instantly shift the whole keyboard Low, Mid, or High • Vibrato - add a gentle, classic pitch wobble while you play • HPF/LPF filters & volume - shape your tone in real time with high-pass and low-pass filter knobs • 4 oscillator voices - switch between Square, Sine, Triangle, and Sawtooth waveforms for different timbres • 4 sound effects - add Reverb, Echo, or Distortion/Fuzz, or stay Dry • Drum loop accompaniment - choose from 8 rhythm patterns, adjust the BPM, and keep the beat going in the background while you play • Record & share - capture your performance, then play back, rename, delete, or share it from your local Recordings Library • Flexible layout - use portrait or landscape, and swap which side the keyboard sits on to match your left or right hand • Light & Dark themes - pick the look that suits your studio WHO IT'S FOR Musicians, hobbyists, and anyone who grew up sliding their finger across a classic touch-strip synth. Whether you're warming up, sketching a melody, or just want a fun lo-fi noisemaker, Glisslo is built for quick, expressive, hands-on play.
