Roland AX Synth ALL 264 Tones in 10 Minutes - by Howard J Foster. I decided to put together a video to show all the tones on the Synth in 10, and the result sounded like an avant guarde composition. So here it is, 'AX Synth'. All the tones are presets other than around 5 of the lead guitar tones which I have altered using the AX synth Editor software. Every sound heard is made by the AX Synth. The only addition to the mix was some extra reverb. Stay tuned for more AX Synth videos.
