PitchTrail lets you sculpt expressive pitch curves directly in your browser — no plugins, no setup. Export to WAV, MIDI, or video in seconds.
Features
Draw natural glissandos, vibrato, portamento, and complex shapes with intuitive control points. What you draw is exactly what you hear.
29 sampled sounds — real piano, strings, brass, choir, and our signature synth pads (Synth Lead, Synth Warm, Synth Halo). Try 3 free, unlock the full library with Pro.
Layer up to 12 independent pitch lines. Each note has its own curve, timbre, volume, and effect. Build full harmonic sequences in one session.
6 synthesis engines — subtractive, FM, supersaw, additive, AM, and noise — each with curated presets that respond instantly to every curve change.
Lock curves to any scale and root note. Combine with the harmonic sequence generator to create complex arrangements in seconds.
Apply Flat, Slide Up, Slide Down, Vibrato, Glide, or Expressive in one click — then fine-tune with individual control points to get the exact feel you want.
Every project encodes into a URL. Copy, share, and anyone can open your full session — notes, tempo, sounds and all — instantly in their browser.
How it works
Click to place notes, drag control points to shape pitch over time. Use freehand mode for organic gestures, or apply a preset shape as your starting point.
Pick a synthesis engine and sound preset. Adjust tempo, bars, effects, and per-note volume. Hear every change in real time — no render time, no latency.
Export studio-quality WAV, MIDI with 14-bit pitch bend for Logic or Ableton, or a video clip ready for social media. Your creation, your format.
