Are you a student? Then you probably don't need all the bells and whistles that go along with a Supersonics Plus Teaching membership. For only $5 USD/month you can practice at home with all the streaming backing tracks and watch all the performance videos. You get:
* access to a library of over 130 super cool pieces
* technology that you can use on any device
* instant speed control
* the option to loop problem sections
* the ability to zoom in and out on the score
* an inbuilt metronome
* performance videos
If you are looking for a more acoustic experience, simply "mute" your device to play along with the scrolling score without the backing track.
You don't need multiple accounts for your family as one membership will cover everyone in the house. The only thing to remember is that you must limit your usage to two devices that you own.
Try the technology now!
