In order for you to be able to do this without any problems, there are a lot of factors affecting this. Here is how you can sample using reason 9.5
Go to NN-XT advanced sampler. The NN-XT is packed with useful features to help you build your own stunningly realistic instrument patches: alternate sample playback, auto-pitch detection, zones with individual parameters, and much more.
From there you can literally change Layers, edit zones one by one. You can even make a record & make it your own.
I would also like to separately note that this is not an easy process that requires training. It is important to Understand What is Production Music and build your further development plan in this area on this.
You'll need a computer, that's at least $ 299 off the bat ... you'll need good RAM and CPU and at least 500GB of drive space. Music stuff takes up a lot of space.
You're going to need a good set of monitors / headphones. I suggest monitors more though, easier to get the mix down the right and ear fatigue is at a minimum. BUT, you're trying to be cost-effective so get headphones. Plus there's no good set of monitors out there that cost less than 200 ...
If you're getting the monitors you're going to need an audio interface. A focus rite 2i2 is $ 200 ... that's almost half your budget ...
You're going to buy software, the cheapest good quality one out there is FRUITY LOOPS, costs around $ 100 But it's only good when you have VST's (external synthesizers and audio engineering modules of the like). They can really spike the price up, BUT it's necessary to compete against the big dogs.
Learn piano. If you're musically intelligent you can just grab a $ 5 chord book off the Apple Store in the form of a PDF and put ideas together and let your creative juices flow….
To be honest, $ 600 for a studio setup is not enough to get the things that matter. It'd be wasted money if you went and bought anything now. Go to Sam ash and listen to speakers and find the ones that really send chills up your spine and make THAT your first hardware purchase along with an interface. If you half-ass it now you'll regret it later. My friend did the same thing and he's done nothing but complains because the quality isn't there so he can't mix anything down. It's just a waste of money, save up more money, at least $ 1200 so you have room to buy what you need. You don't have to spend the whole $ 1200, but it'll stop you from making unnecessary sacrifices from square one. :)
PS: my setup without my computer came up to around 1k, but I haggled the price down to $ 800. And I went in with $ 1200 so the rest of the money I kept and I was happy cuz I saved a lot of money and regretted nothing because I had everything I wanted at a discount.
WITH my computer it would have cost 2k before the haggling.
Also, you don't need to buy it all at once. I had my laptop for 2 years before I copped the full studio. I thought headphones were godly for mixing the whole time (I was naive). BUT, I was able to learn how to create because I had the DAW and a PDF to learn music. So when I got the full setup I wasn't stuck lol.
I hope that helps.
