A music practice app, built while learning guitar.
Yalaloop is a music practice and transcription app for slowing down, looping, and pitch-shifting any track. You bring your own audio files — songs, lessons, recordings of your teacher — and Yalaloop gives you the tools to pull them apart at your own pace.
You can drill the chorus at 60% and the solo at 80% in the same session. You can mark passages, name them, and come back to the same loops with the same settings every time you open the file. Speed and pitch are independent: slow audio down without changing the key, or transpose to match a different tuning.
I started building Yalaloop while learning guitar. I was constantly editing audio files to create slowed-down loops — pulling a phrase out, dropping the tempo, looping it for repeated practice — and ending up with a folder of half-named clips I could never find again. And none of them were on my phone when I showed up to a lesson.
That’s the gap Yalaloop tries to close. Generic media players let you scrub and pause, but they don’t remember where you wanted to loop, what tempo you set, or which markers you placed. Yalaloop keeps all of that per track, syncs it to every device you log in on, and gives you sample-accurate looping with a short crossfade so the seam doesn’t click.
I built it because I needed it. I use it every day.
More on how I actually use Yalaloop for guitar practice — concrete workflows, the songs I drilled, the tools alongside it.
Yalaloop is deliberately focused. A few things it doesn’t try to be:
I’m Michiel van Vlaardingen, a developer from the Netherlands who plays guitar.
Yalaloop is the first app released under Melody Matrix, a broader project I’m building around music practice — curating the best online resources for guitar players and developing tools that fit alongside them. Yalaloop covers the slow-down-and-loop workflow; the wider toolkit is still to come. Both ship under MovingLabs.
A few principles drive the choices in Yalaloop:
The fewer steps between wanting to loop and actually looping, the more you'll practice.
Yalaloop gets better when people tell me what’s broken, confusing, or missing. I read every email.
