Awesome app!

I bought this app a little over a year ago, and it’s my go to for aria practicing/recording. I love that you can slow or speed up the tempo, and you can change the key it’s in. I requested an aria that wasn’t on the app, and Dr. Wong emailed me back within two hours with the rep I needed! Highly recommend for any classical singer/musician!

This is a dream come true!!! Thank you for this app, it works so well and is a pleasure to use. Is there any possibility of using the track in recording? Or exporting tracks ?

Developer Response ,

Thank you for the feedback. It's definitely possible to capture your screen's audio and video while the piano part is playing. For example, the link below offers a good reference. Hope this helps! https://support.apple.com/en-ca/HT207935

Great app — a few suggestions

I am really excited to use this with my cello students. The only thing I would like to see is a temp given before the star, could be a flash if not a count in. Would be helpful to also have the measure marked if you stop. But as someone who has very basic skills it’s nice to have the accompaniments of many of the pieces I teach.

Thank you! If you are interested in having measure numbers displayed along with tempo markings for your accompaniment tracks, we do have a parallel product that serves this purpose at: https://4djam.com/jam
