Live lessons & MIDI sync

MIDI-compatible instruments built right into our app

Works alongside the gear you and your students already own.

  • Built-in instrumentsPlayable piano, Rhodes, Wurlitzer & B3 organ in the browser — to complement your own setup.
  • Bring your own gearPlug in your MIDI keyboard and audio interface; Syntonia plays nicely with it (ASIO on Windows, Core Audio on Mac) for tight, low-latency sound.
  • Live MIDI syncPlay, and your student's screen lights up and sounds in real time — and theirs syncs back to you.
  • Live chord readoutNames exactly what's being played — chords & intervals, right on screen.
  • A reliable backupStudent between instruments or travelling? The in-app keyboard keeps the lesson going — a backup, not a replacement.

Courses

A guided, custom course — built by their teacher

Not generic lessons. Each student gets a personal miniseries from you — chapters and sections you design, in the order you want them learned.

  • Their teacher's courseStudents open a clean, branded course player and work through a custom miniseries you built for them — videos, notes, sheet music and files at every step.
  • Linear or non-linearLock it linear so each section unlocks only when the last is complete — perfect for beginners. Or go non-linear and let students roam freely and review anything, anytime.
  • Free if you wantEvery course can be 100% free — only put a price on it if you choose to. (During beta, all courses are free.)
  • Track every studentSee who's at 0%, halfway, or finished at a glance, and link assignments to any section.
  • Simple editor behind itYou build it in a drag-and-drop chapter/section editor (shown here) — students just see the polished, guided course.
