Free App Fridays: Beamz
This is sort of an odd case as far as free Apps go-- while the app is free, it's meant to go with a piece of hardware that isn't. Still, the app is still functional as a stand-alone app.
Basically, Beamz is a music making device by Beamz Interactive, Inc. If you purchase and use the Beamz controller, you are able to control music by interrupting laser beams with your hands.
This is a gadget I've used before in music therapy sessions in a previous job; it's great for working with clients who have limited mobility (say, because of cerebral palsy) and it's incredibly fun to use.
But even if you don't have access to the physical controller, the Beamz app allows you to do the same thing by touching images of the beams on the app screen.
The app comes with several pre programmed rhythm tracks, each with twelve instruments that you can control. (There are also more rhythm tracks available for purchase) The songs are in a lot of different styles, from classical to hip hop, and a lot of fun. There is also a recording feature so that you can record and replay your work.
