Clearing ARPs and RPS.

I cleared mine out by mounting the Fantom as a drive on the computer and then deleting all the phrases I didn't want.

I can't see a reason why you can't load up the Fantom with the exit button held down (so it loads blank and fast) and then save that empty one as a new project and you have a quick one to load up off and add what you need.

You will lose the new user patches that were introduced in later releases doing the last method tho
