I am really very thankful to every member who took the time to reply to my request. I am still undecided as to what keyboard to go for but I am leaning towards the Korg
I had a Tyros 4 for some time ago and I didn't keep it very long as I didn't think it suited my type of music as well as the Ketron.
I also have a Korg Microarranger and I am wondering what the PA4X instrument sounds are like in comparison to it.
