Hi, new to this and not very good at navigating forums, so this maybe already covered. Just got a brand new HX Stomp, says it's version 2.65. So do I just download the latest (version 3) or do I need to start with the 1st one after 2.65 and through to 3.0. Also where do I get the the Editor? And do I need to download anything else? Thanks
