01. What it does
Ramp up to speed, pass by pass
Pick a loop and SoloTrainer plays it back faster every time around — 50%, 60%, 70%… all the way up to full tempo. It's the classic way to build a fast solo into your hands. Set your start, target, and step, then just keep playing.
Load straight from YouTube
Paste a YouTube link and SoloTrainer pulls the audio right in — no separate downloader, no sketchy converter site. From a link to looping the solo in seconds.
Isolate or mute any instrument
Split a song into separate vocals, drums, bass, and other tracks with AI source separation that runs right on your machine — nothing gets uploaded. Mute the part you're learning and play it yourself, or solo a single stem to hear exactly what it's doing.
Speed without pitch
Slow a track from 25% to 150% to catch every note — the pitch stays exactly where it was.
Pitch without speed
Transpose ±12 semitones to match alternate tunings or sing it in your key — tempo stays put.
A–B looping
Drop a start and end point right on the waveform and loop a tricky passage until it's locked in.
Section markers
Drop color-coded markers for verse, chorus, and solo, then jump between them with a keystroke.
Full waveform view
A scrollable waveform with a compact overview, live playhead, and your loop region overlaid.
Drag & drop any file
Load MP3, WAV, M4A, AAC, or FLAC. Drop it in, click the waveform to seek, and start practicing.
