This is the future of music rehearsals.

This is the perfect app for people like myself who like to play along to their favourite tracks when rehearsing a musical instrument.

It’s especially good for multi-instrumentalists who want to selectively remove certain instruments to practise each one individually without having to fight for presence in the audio track.

I’ve used several other stem isolation/instrument removal services and apps, but I’m amazed how well this one works, and in real-time, no less.

Jam along (in whatever key I want)

I love being able to play along with a variety of songs; the pitch adjustment is accurate and really fun to use as well. I often find myself tapping on the iTunes music button to buy the entire songs of my favorites.

Game changer!

Flawless audio separation. Quality and functionality are excellent. Intuitive design. So much fun to play around with. Only wish I would’ve found this sooner so I didn’t waste my money on apps that don’t work in real time.
