Roland Sysex Generator

Simple script to generate sysex packets for Roland Synthesizers both send data (DT1) and request data (RQ1). Can generate multiple requests at different addresses to poke around. Works with 3 and 4 hex digit addresses. From your friends at Spluge.foo.
Only use if you know what you are doing. No warranty is issued or implied with this code and if somehow this knackers your machine, don't blame me.
