But I'm posting again! WHOOA!
Anyways, I think it would be nice to actually post about something with content this time and today my sister told me that she was thinking about getting a keyboard (like a musical one). Then she went on to say that she wants one that's not too expensive and not too cheap or I dunno. I realized she was talking about a synthesizer and not just a MIDI keyboard which is now a day synonomous with USB keyboards. So why get either? Lets discuss.
Synth:
These are way expensive. The Korg R3 just came out for ~600$ and is one of the few that I would seriously consider buying in that price range. It only has three octaves and is not a full range keyboard although it has enough functionality to get you through some production sessions. This is the next level of the microKorg but it has more and better features, an XLR mic (for the vocoder) and some other goodies. Not to mention the keys are full size vs. the microKorg which were bite size.
There are definitely other good synths out there in this price range but if you want to get something that will really be useful outside of a small range you are looking to spend a whole lot more money, and as student or a non-pro musician it's a little non-sensical. Truth is, if you really want a specific synth sound then go for it. I remember I was so obsessed with this old Yamaha synthesizer back in the day and I still to this day know that if I find it somewhere I will buy it on the spot. Also synths are good for live performances and when you don't have time/space to fuss with other things.
Also synthesizer don't always come with keyboards attached. You could easily buy a much better synthesizer module and hook it up to a simple M-Audio midi keyboard and save some money and be a superstar. Killing two birds with one keyboard.
MIDI/USB:
Personally I feel this is the best solution. There are some amazing products out there. They can be completely powered through USB making them even more portable. I could potentially hook up my Kontrol49 to my laptop if I'm out in the boondocks. There are some classy solutions being made today as well. The Kontrol49 is my favorite sporting 49 keys, an AKAI like drum pad and 8 up/down faders as well as 8 knobs for tweaking everything live. It's a bit expensive, I got it at half price on ebay but new this little guy will set you back $400. There are cheaper M-Audio solutions in the range of $300-200 and they have everything from piano action keys, to drum pads, more knobs and up down faders. All depends on what you want out of a controller.
So what the difference? Well, a MIDI/USB controller is only as good as what it's plugged into. This will either be a real synth module (which is expensive) or software (which is significantly less expensive and many times can be accessed for free for a period time or through limited functionality). Now as an engineer I can tell you that some of the modules you get as software will sound indistinguishable from their real synthesizer counterparts.
Synthesizers are made through the use of specialized signal processing processors embedded into the thing. These execute specialized programs just as your normal computer would but run way slower with much restricted resources. As personal computers have gotten better the need for synths has gone down since you can EXACTLY emulate these processors on your intel supercomputers. Your real computer is drastically faster than the synth and has way more memory etc. In fact you can exactly replicate these synths and also come up with more exotic and complex sounds than the synths can through a computer. So in the long run you pay less money and get way more functionality.
You will need to get a DAW (Digital Audio Workstation (software)). This software will allow you to hook up to your keyboard and interface it with multiple instruments, record and play it back. These programs allow you to add effects and whatever you want allowing for a much more conducive producing experience than buying one synth and running it through a hardware sequencer or simply using an 8-track recorder or something. Some notable programs are Ableton Live, Reason, Fruity Loops, Cubase, Logic, and Pro Tools for the rich type.
Conclusion:
You can already tell I'm biased but I base it on the fact that I'm poor, have not too much time for this stuff, and know two cents about technology. The only issue not mentioned is latency and with midi/usb you will need to juggle a few things to get your latency to an ok level. Human beings have almost an impossible time differentiating between two sounds 20 millaseconds apart. Above this latency you will feel it (like a bad day at Guitar Hero) and below you won't be able to really tell that there is any difference between you pressing down a key on your keyboard and the sound coming out of the speaker. Synths are somewhat better to deal with this problem but you pay a whole lot of money to do something you could figure out over the span of a week. Just takes some tweaking of your drives, settings, and whatever.
If you have any questions feel free to comment! haha. PLEASE! I will answer them I swear. And when I get some free time I am planning to start a DJ Tutorial series on my website. First just recorded voice mode but I will eventually video tape it and host it on youtube or something like that. To not only illustrate some of these ideas in this entry but others pertaining to the core of DJing and Production.
To Life!
