Not every one has a 303, Maybe they want to take that cheap Behringer mono synth and do acid on that?
one could argue what made it great was that it only has 5 parameters that affects it's sound and it's sequencer, (and it was a total flop financially for Roland and could bought 2nd hand for like 50 bucks in Detroit. and dance music is better for it!)
and as per the subtractive synth that change music the most...I'm going to go with Moog or mini-Moog, without them there's no 303, 101, Juno, Jupiter, etc.
I love me some good acid-house though, and much rather have a 303 then a mini-moog. :)
That is the point of making music.
The rest is exhaust fumes.
You don’t have to know how something works to know how it sounds.
And nobody ever danced to a lecture on signal flow.
