  1. 01

    Loop it

    Press A where the passage starts and B where it ends. The seam back to A is click-free, and you can keep as many named loops per song as you like.

  2. 02

    Slow it

    From 20 % to 200 % without changing the pitch, or up to two octaves of pitch without changing the speed. The loop trainer raises the speed for you as you get it clean.

  3. 03

    Learn it

    A gap between repeats to play it back, a count-in, lyrics with chords that follow the key, your notes and bookmarks: everything stays with the song.

What you get

Named loops, each with its own settings

A warm-up loop at 60 %, the hard bar at 50 % with a two-second gap, the chorus at 90 %: one song, three practice settings, remembered.

Speed and pitch, independently

20–200 % at the same pitch; ±24 semitones with cents and a reference pitch at the same speed. Two engines to compare live.

The loop trainer

Start at 60 %, reach 100 % in steps of 5 % every three clean passes. Presets you keep and use on any loop.

Hear the part

Mono, left or right only, centre cancel to take the voice down, stereo width, and a ten-band equaliser with presets.

Lyrics and chords

Paste chords-over-lyrics text; the chords transpose with the pitch shift, with a capo option and guitar shapes.

Video in sync

Music videos stay in sync at any speed and pitch, docked or full screen; step frame by frame to study a fingering.

Bookmarks and notes

Named positions you jump to by key, and free text with the song for fingerings and homework.

Yours, offline

No account, no cloud, nothing sent anywhere. Sync between your own devices through your own storage, encrypted if you like.

Every key, every reader

Everything has a keyboard shortcut you can change; VoiceOver and TalkBack name every control; text up to 200 %.

For teachers

Prepare the song once: loops for the hard bars, a trainer plan, bookmarks, notes and the chord sheet. Hand it to the student as one bundle file. Their bookmarks come back the same way, and a second bundle never deletes anything of theirs.
