Hi I am considering buying either a Tyros or a Pa 80.I particularly want an arranger keyboard that enables me to edit my arrangements with a list edit function.ie I want to be able to record my song live in the style and afterwards be able to correct chord entry mistakes (ie chords too late or the wrong one etc).I also want to be able to easily mute tracks in the recorded song and be able to add my own tracks to it.I would also like a style morphing function if possibe.I would also like to be able to change styles within a song if possible.Sorry to be asking so many questions.I recently bought a roland va7 but was dissapointed with its lack of editing functions.Also the variphrase didn't work properly so I am able to take it back to the shop and change to another product.At the moment my choice it between these 2.I have used a korg i5m in the past and really enjoyed using it so am tending towards the PA 80.HOwever the posts about the tyros indicate that this might be a better choise.Thanks Rod
