I think a large part of this issue is related to the GAS problem. All those neat looking generally affordable gadgets with delicious blinking lights quickly make a studio look sophisticated and professional. Folks buy heaps of them, until the music they produce is the result of trying to incorporate some of them, or as many of them as possible, into each song. But the GAS is related to the instruments also, in that folks want to buy one new or different instrument after another. The result is that they quickly grow bored with the instruments they presently own and fail to deeply explore and push any one instrument to its capacity.
By contrast, imagine the pianist who has only one sound, and must learn how to make the most of that sound for a whole life time, drawing out from it all the subtle nuances and variations possible. I must admit, that simple and direct approach, that resourcefulness, fills me with admiration.
For all the years I was a church organist, I never once thought of buying organ-related objects. When I studied harpsichord, I never thought of adding harpsichord-related gadgets to my music room. It was 100% about the instrument and what my mind, hands, and feet could do with it. And that's exactly how I approach the synthesizer.
