I'm with Dave regarding sampled analogue sounds I'm afraid and I would never use such a sample.
I've been into "synthesisers" since I could afford my first ever which was a weird plasticy affair called a Wasp.
Since then I've owned a Multi Moog (which blew up else I'd still have it now), a Roland Juno 6, a Roland SH101, Bassline and Drumatix. They were from the true analogue days.
My current arsenal of VA synths are a JP-8000, an OB-12 and a Novation Nova.
The reason I'm telling you the above is because I'd like to express how much I know, and indeed love synthesisers, especially of the analogue type.
I never got into the likes of the FM synths and I just hates the DX7.
Anyway, onto soft synths.
For quite a while now I've been into Absynth and I got into that at version 3 and currently use 5. I hardly have any projects that do not have at least one instance of Absynth.
I used to enjoy Pentagon but I've given up on it now because I got fed up of remembering to run Sonar as administrator.
Very recently I discovered A|A|S and their suite of VST instruments. I eventually bought one of their bundles and my favourites are Chromaphone, UltraAnalog and both of the Strum modules. I have Tassman too, of course, but unless I can find a preset I can tweak I don't really use it that much. I'd rather spend more time composing that sound design. I think that's where UltraAnalog comes in, because you still get some of the great Tassman sounds but with a traditional analogue synth interface.
Chromaphone is one of my favourite percussive synths. And by percussive, I mean anything that can be struck or plucked. I would normally turn to Absynth for that duty, but Chromaphone fits the bill perfectly for me.
And one big thing I've learned over the years is that there is no such thing as one killer synth. For me it is very much a matter of choosing the right horse for the right course.
Oh, I don't do EDM by the way. At least not on purpose. I prefer old fashioned synth music as was created by early Tangerine Dream and Kraftwerk. If I wanted popular then I'd listen to a bit of JMJ. So that is the kind of stuff that I like creating myself.
Thanks for posting the original thread, I enjoyed reading through all the posts :-)
