I agree, From the sound of it, You arnt too much into actual "recording", So id leave the mic's, mic pre's, ect out of it.
You have FL studio.. Do you like it? I PERONSALLY, like it much better than reason. Maybe had i of learned reason first, it may of turned out different. But so far, FL dont limit me one bit.
If you like FL studio, Stick with it, And upgrade sounds, ect.
Your talking about upgrading "EVERYTHING". That may be the worse thing to do, As im sure you couldnt just walk into Guitar center and come out with your dream studio at the moment [Atleast, Without a big bill at GC.]. Meaning you'll have to skimp out on important area's, for not so important area's.
If i were you, Id look into these item's:
Things you basically can't be without:
- sound card -E-MU 0404 sound card [This, would be something id Definantly get, if your still running onboard sound.]
- Monitors - KRK rocket 5, or 8's. [Id also look into these, or a nice pair of headphones (Senhieser 280HD's are my fav.), as itll give you a feel of what your truely producing. Im still using a home theater system, Which colors the sound, meaning to me, it sounds good. to someone with monitor's, Sounds like junk.]
More sounds [We all know FL is limited.]:
-Emu Mo Phatt module
-NI KOMPLETE [Mainly Battery, And KONTACT.]
-Sample tank
-A decent Turntable + Pre-amp, And records to sample from.
Hands on / controllers:
-AKIA MPD16 [Or if you must have the fancier version's, Id go KORG PADKONTROL.]
-M-Audio Radium49 [Or you could skip the MPD/KORG, And go with a M-audio axiom, which has 8 pad's, and 25/49/61 key's, along with various knobs / fader's. For about the same price as both unit's.]
[Dont get me wrong, Theres different option's, This is just the route I would / Am taking.]
That list alone would make a guy with just FL7 VERY happy for a while, Provided they didnt get overwhelmed with the learning curve, And is basically the cheap / Budget way to go, with a software set-up.
Someone mentioned a mixer. I dont see where you'll need one, Untill you start adding multiple sound sources, Ect. Dont skimp here, But dont get it if you dont need it.
