I wish to create sounds like they are by example in psy-trance.
I'm not very familiar with that genre (link Youtube). But i think the synths there are mostly "pads". String/orchestra like, lush and with lots of reverb.

So, it will be by example basses (like house basses), of course some percussions, background (ambience) sounds too and several "master-sounds" (I don't know how to describe them ; typically "electronic music sounds" - techno, house, etc).

Is this your first synth or are you familiar with other synthesizers/synthesis concepts?
It is my first big and serious experience with a synth ; I only "played" with synth in the past. I feel I need some synth theoretical knowledge.
NB : I am engineer. I know what is a signal, amplitude/phases, I am used to Fourier and spectrum, etc.
The easiest to start (and the only thing I'm personally familiar with) is good old subtractive synthesis. Especially if you're an engineer. The virtual synth you'd like to use (Surge XT) comes over as a bit complicated to me: the website says it's "subtractive hybrid". But I can't figure out what that other part from the subtractive part is. And it's not up to me as a user to go on a wild goose chase because the manufacturer of something isn't crystal clear about it's product.
Anyway, I'd start with studying a straight forward subtractive synth like the almighty Mini Moog. Everything that's important to subtractive synthesis is on there:
-
Oscillator (tone generator, wave forms)
-
Filter (high pass, low pass, etc.)
-
ADSR envelope generator (for amplifier and filter), ADSR = attack, decay, sustain level, release
-
LFO: low frequency effect (sometimes called "modifier")
-
Glide (glissando)
On the Mini they're named different but try to find info on all of 'm. Are you a member of a synth forum? They might give you more pointers.
The sound that an oscillator makes goes through a filter (usually low pass) to give it some character. With an LFO you can "modify" a note's pitch up and down a few times per second automatically and/or the cut-off frequency of the filter (as in: "wow wow wow wow wow wow ..."). Slowly letting the volume of a note swell up is attack time of the env. gen. Et cetera.
Forget about FM sysnthesis: incomprehensible.
And then there is monophonic and polyphonic synths: mono means one note at the time is played (like the Mini Moog), polyphonic means that you can play multiple notes in chords (like on a piano).
Good luck!
