You’re absolutely right! Both are actually quite easy to pinpoint the prime time dacade of, and the 80s sound is no doubt more trendy right now in general. That said, objectively speaking, I would think that a subtractive analogue synthesizer will be a lot easier to make timeless and bring into a more modern sounding track due to its flexible nature. Add a quick filter decay on a saw with a hint of detuning and some noise and you’ve got a pretty timeless pluck. Not so much with a kalimba sample.
Perhaps the JD-08 can do that too though; I’m sure it has a few of those standard waveforms as part of its pcm bank. But if it does, the demo of it certainly didn’t give that impression as nearly all of the sounds had that 90s Fångad av en stormvind vibe to it (search for it on YouTube, you’re in for a treat! ).
Ultimately the JD-08 feels a bit like “here, you get a synth with 100 built-in sounds that you can mix and max however you want!” That said, I do look forward to hearing what interesting new sounds users will generate with it given that the JD-800 has never been more accessible than now (read: January 2022). I’m guessing it will be a really useful pad generator. And I’m sure it’s ahead of its time because inevitably, the 90s is bound to get trendy real soon!
