Made by musicians, for musicians.

Riff Studio lets you build a setlist of the songs you want to practice, set their pitch and speed independently and before hand, so you can focus on playing your instrument or singing along!

You can also adjust the song parameters at any time and in real-time: either set the pitch without affecting the speed, change the speed without affecting the pitch, or adjusting both together. The pitch will be set in semitones, and the speed as a percentage of the original speed.

It also provides bookmarking and A-B looping functionality to go through those difficult parts until you get them right. You can also use the quick-jump feature to jump back to the last point you started playing from in a song, seamlessly.

Besides from the in-app experience, Riff Studio also lets you save or export the adjusted songs to your device in MP3 format.

Riff Studio is great for musicians practicing songs that require alternative tunings, or that are too fast to play along initially, and will help them get all the way to 250%.

The user interface is clean and touch targets are large, which enables an easy interaction that doesn't require fine motor skills, so you can focus your dexterity on the instrument you are playing instead of on operating the app itself.

Riff Studio is in continuous development, eager for to user feedback and feature suggestions. Please shoot me a line at brazzilabs@gmail.com with your ideas!
