A synthesizer forum is both the best place and the worst place to have this discussion. I'm ready for the virtual tomatoes.
We all suffer from it, to one degree or another: the hunger for a steady supply of equipment. It's like an addiction, or perhaps more like an obsession. Whether new or used, we crave for constant changes to our set ups, to see stuff coming and going. We buy the latest piece, use it for a year, and then sell it on Craigslist, Ebay, or Reverb. And the reason we sell is so that we can buy something else. And when we're not buying or selling, we're researching equipment we don't yet own but are dreaming we one day will. In fact, we spend far more time on YouTube and Soundcloud listening to other people demonstrate their instruments than we do sitting at our own instruments making recordings of our own material. And speaking of our own material, rather than compose actual completed pieces of music, we, too, create primarily instrument demonstrations for the others who similarly suffer from Gear Obsession. Around and around it goes, providing a massive movement of cash and credit flow, but very little high quality synthesizer music.
We tell ourselves we don't have a problem, and that, with the next few new pieces of equipment, our vision will be complete and we'll finally be content. No more spending for us. But once we've had that new stuff for a mere two weeks or so, we're already daydreaming about another new piece of equipment - while we're driving to work or lying in bed at night. In fact, we reserve all our extended periods of thinking, and even look forward to them, because we intend to spend every minute thinking about gear. If we have composer's block for weeks on end and feel drained of all inspiration, then we attribute it, not to a lack of ideas, talent, or ability, but to a failure to stock our studios with all the right gear. And our poor wives or girlfriends - they have to endure our technical twaddle day and night, and wish that they excited us half as much as does a brand new, or newly restored, piece of gear from some distant techno-geek's workbench.
To give one example, my wife's eyes instantly glaze over as soon as I say the word "oscillator". I know of no other word that has this effect on her. Once I utter the word, she's instantly and involuntarily adrift in the ionosphere, and I can only bring her back by changing the topic.
If I can describe the above disorder with such detail, then I must have a degree of firsthand experience with it.
I have one suggestion that I've learned to follow, partly due to a limited supply of disposable income.
You're never going to have the perfect set up. So, design one that is good enough and be happy with it. Cut back on the demo videos; reduce your research time; stop looking outside of your studio for satisfaction, and get to work with the equipment you own.
We do not suffer from a dearth of musical tools, but from the discipline of assiduously using them to good musical effect.
