Digital vs analog synthesizers: a question for synth-heads and audio experts.

[I Got A Letter]

I'm generally an objectivist and believe that if two devices measure the same, they will sound identical.

I own several synths, including the analog Behringer Poly D and Pro-800, as well as the digital Novation Mininova. In theory, the Mininova is the most powerful of the three, with features like multiple envelopes and filters, a modulation matrix, and built-in effects. However, when compared side by side, its oscillators sound "thin" and less subjectively pleasing than those of the analog synths.

I'm not suggesting there's any mystical "analog magic" at play. I'm confident that the analog and digital outputs would measure differently in this case, and a better digital oscillator could likely match an analog one. What I’m trying to understand is this: in this specific instance, what might be causing the digital synth to sound worse? Could it be the filters?

I don’t think I have a particular bias toward analog, though all my comparisons have been sighted. That said, the differences still seem striking—dare I say, "night and day."

Assuming there's really an audible difference, you should be able to find out why by measurement. Use something like REW to see the frequency spectrum of each. Any DAW should show the envelope.

Sorry Im late to this but......

Could I propose a suggestion before you ask the question.

Could you look at how you are hearing these differenc4s. Yes using REW could be a good indicator but it may be the amplifier a new clinical Class D as opposed to an old A/B with tone controls combined with a set of small active studio monitors as opposed to an old bass reflex two way with soft tweeter.

Also the synths analogue outputs could be affecting the "tone"?

It does not matter what you use as long as the result is what you want. It's an instrument, not a reproduction device, so all what is important here is irrelevant for instrument. You also don't want a low distortion guitar amp for your stratocaster guitar...
