Beat Blocks is music creation experience created by GranddadGotMojo, which allows you to easily build a music track using blocks (hence the name). According to the instructions that GranddadGotMojo placed on GitHub:
Beat Blocks is an experience in Sansar where you can do you own Live DJing. You can create music by adding beats to build up a song. The main component for building up a song is the Beat Block. A Beat Block is a 1/2 meter cube that is initially stored on shelves that are in the Sample Warehouse. These shelves are on the right hand side when you enter the Experience. Each Beat Block contains a sample which is basically a short recording of music. Examples of samples are drum beats, bass lines, guitar riffs, keyboard riffs, lead riffs, pads, risers, etc. All the basics of modern Electronic Music. There are over 400 Beat Blocks and corresponding samples in the Techno Experience using Beat Blocks. These samples are arranged on Shelves by Instrument Type. There is a shelf for Drums, Bass, Guitar & Keyboard Instruments, Leads & Vocals, Effects and Pads (Strings and Ambiance).
Essentially, you pick blocks from the supermarket-like shelves on your right, and place them on special shelves on the left in order to activate them. It’s very easy to use!
Here is an 11-minute YouTube video that GranddadGotMojo created to explain in more detail how Beat Blocks works:
Next to the spot where you assemble techno tracks is a spacious dance floor, where your friends can dance to the grooves you create! Beat Blocks is great fun, and I would encourage you to visit this Sansar experience and try it out for yourself.
