It is a good suggestion from JRIDES. Reason being is, if you ask for an opinion of what to get here, you are going to get specific suggestions from one or two people, but being in that thread, allows you to do research and see what the trends are, in terms of what people does everyone seem to recommend.
Still, I do remember when I first came to GS, I did find it intimidating, in that it was a massive wave of information all at once and it takes time to understand the lay of the land here, so I will give you some suggestions from my point of view BUT I do recommend you follow JRIDES suggestion. That way, you get to form your own opinion, rather than having a load of other people's choices thrown at you.
Ok, you mentioned a Keyboard, MPC and Mixer (I am, assuming you meant a digital mixer controller?) If so, I would get one of these. MAX49 USB/MIDI/CV KEYBOARD CONTROLLER
You get the Keyboard, MPC pads and digital mixing controller strips. If you meant an analogue mixer, it would be good to know how you intend to use it, to get a better picture of how many channels you might need and whether you will required busses and effect sends or not.
As for Synths, I don't have any of the new stuff, but I can recommend a couple of the cheaper old synths I have had experience with and hell you can get most of it at amazing prices second hand these days. Access Virus
(Any version, rack, desktop or keyboard). Amazing sound, menus are pretty simple and loads of genres get covered by this beast. They go for good prices these days, compared to what they used to be new. Akai SG01v
for me, this is one ugly fecker, but they go for pittance on ebay and they sound marvelous (Akai SG01v
). If your budget is tight, this could sort you out. Yes, there are some cheesy sounds on there, but there are some killer sounds and it covers alot of basses Roland JV1010
Another great sounding cheap synth on the second hand market. I never get bored of Roland leads or basslines. Always very very useful
They are others but we could be here all day.
I don't know FL Studio. Never had any experience with it, so cannot comment. As for Reason, I think it is MARVELOUS. Never comes across something where you can get ideas out so quickly. It's great sounding, especially the Thor synth and it has useful effects too. I would recommend this to anyone, even if just to use it as an idea engine.
Ableton, I hate it. Bought 7, used it twice, never used it again. Waste of money for me. Other people love it like it is BBQ, but it didn't click for me. Hated the workflow. I use Cubase, Reason and Logic and I like all three. Would recommend Reason for being a purely creative tool, but I don't rate it for mixing. If I want to mix anything out of Reason, I export the stems and mix in Cubase with plugins like UAD. Rewire is ok, but then you have two DAW's open using resources, so stems work better.
