Loop+ bring you this useful Ableton video tutorial from Point Blank's Jonny Miller on how to make a dub siren in Ableton, with the Analog synth instrument.

Although it's named after Dub, you've probably heard a Dub Siren used in all kinds of music and DJ sets. In this video Jonny demos a hardware dub siren, and then shows how to make one in Ableton Live using Analog, Overdrive and Ping Pong Delay. The tutorial explains the process from scratch and ends with a nicely set-up Instrument Rack, complete with macros that mirror hardware dub sirens.
