I haven't had GAS in a long long while...the arranger keyboard I've been using these past several years is programmable so it basically doesn't get obsolete as I can update styles and sounds as necessary. The only things that will eventually wear out would be some of the hardware bits, but that's common for most electronic keyboards. Even acoustic pianos need maintenaince, such as tuning and regulation.
So I basically spend nearly all of my music related time actually playing and, either learning new tunes, or refreshing the older ones. The technology works for me, not the other way around.
I also play non-arranger keyboards several times a month, such as a beautiful vintage Hammond B-3 and occasionally an 88 note weighted action electronic piano, usually a Yamaha P-85, so I manage to keep those chops up fairly good, although my "main squeeze" is still my Tyros4, for its sheer versatilty. I like how it gives me the ability to play entirely on my own, with a virtual band (of my own choosing, I might add) that will play swing, rock, country, electronica at any time of the day/night I so desire.
For impromptu jams, having an Arranger Keyboard is pretty handy...just shut off the arranger parts that are being played by live musicians, or just use the instrument without accompaniment as you would a regular keyboard/synthesizer.
Since retirement I am thoroughly enjoying playing the music I want to play instead of having to choose tunes that showcased the instrument's features as was required on clinics/demos, although I still regularly pick tunes that challenge me and take me out of my comfort zone. I still exercise my sight reading skills.
Talking with other keyboardists on Skype, and watching players on YouTube also keep the lines of inspiration open.
So, to sum up, I spend most of my time actually playing keyboards, and try my best to keep the style/sound programming and other technical doodling to a minimum.
