I know, Donny, that you are strict about the “no hoarding” rule and this rule is partly a reason why you try to limit a number of instruments you have down to one. But it is also vital that you actually like more than one keyboard and personally I don’t think that this “hoarding” term applies to things which are actually being used. Certainly, I don’t have a full picture of your needs and reasoning; it just seems to me that having E-A7 together with some Korg, Yamaha or Ketron keyboards can get you more focused on music rather than on managing all these changes. But maybe there is such a thing as too much focus.
I already went thru that horrible HOARDING Phase in my life years ago and was lucky to be able to kick the habit. I have been clean for years now and feel so much better not looking at stuff all over gathering dust in the corner, against the walls, in the closet, garage, etc, ....some can live with that but I cannot anymore.
One is enough....but it has to be the right one .
