First point to address is : what do you need to make music? It’s always been my belief that you don’t need expensive instruments or gear to make music. A 3000€ guitar has never ever turned a mediocre musician into a good one, and the same is true with synthesizers. There are on this planet a number of people able to produce insanely bad music with outstanding electronic instruments. I can prove it. I’ve seen the Youtube videos. You have too.
That said, what a pricier, more sophisticated synth might grant you is more versatility and higher quality sounds. When you want to add Moog sounds to your music, and can afford to go hardware, the best choice is a Moog synthesizer… which comes at a price. But it remains that every synth, no matter how primitive, can be put to intelligent use and good music.
The second point is : how much is too much? What’s the limit between reasonable acquisition of valuable gear and compulsive buying of new junk?
Am I addicted? I don’t think so. I realise that from now on, every synth I’m buying, I don’t really need. But here’s the third point : it’s fun to buy new toys. For months now I’ve been looking for a Roland D50, or better, the D550 rack version. Why? Because that’s one instrument that made me drool when I was a teen. It was the kind of big, fancy, pro, oh-so-expensive synthesizer I was hearing on all these late 80’s records I loved, one I couldn’t dream of owning. Now with a little bit of luck you can find a D50 for 250€, which is ridiculous considering the power of the machine, and the original price tag. Do I need one? Hell, no. Would I just love to play these classic 80’s sounds of my childhood? Hell, yes.
