It was developed to be as simple and general as possible, to give synthesizer manufacturers as much flexibility as possible, yet still have their instruments talk to each other without communication problems.

Raspberry Pi as an Ad Blocking Access Point This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it.
