Scratching the surface: DJ'ing with your Mac


It's Saturday night and you're out and about painting the town red, or whatever color it is that towns are painted these days. Whether you end up at a night club, a lounge or a bar, there's a good chance there's going to be a DJ spinning up some tunes at the venue. And there's a good chance that you'll see a glowing Apple in front of the DJ, as said DJ may be accompanied by a MacBook or MacBook Pro. If you've ever looked into doubling your Mac as a virtual turntable, then this post may help you scratch the surface -- err, vinyl.
At the top of my list for DJ apps is Serato Scratch Live, commonly known just as "Serato". Although the software-hardware combination of Serato is also compatible with Windows-based machines, most DJs that I know, and most of the DJs in the venues I've been to, outfit their Serato setup with a Mac. Here's what's in a typical Serato DJ config:
  1. There's Serato Control Vinyl. Although it looks and feels like a traditional vinyl record, Serato Control Vinyl doesn't have any pre-recorded music on it. Instead, the record contains a control signal that allows Scratch Live (the software on your computer) to track the motion of the record -- allowing you to control and scratch the the MP3s or AACs on your computer. The price for Serato Control Vinyl records ranges between USD $10 and $20.
  2. Scratch Live, which is the software that's installed on your computer.
  3. To bridge the digital world (Scratch Live and your digital music) and the vinyl analog world, you'll need to use special hardware: either Rane's SL 1 or SL 3 audio interfaces. These breakout boxes connect to your computer via USB. Audio is passed to the breakout box by connecting your left and right turntables' respective RCA cables to Serato's inputs, and likewise Serato's outputs to your mixer.
While you can purchase Serato Control Vinyl and a Rane SL 1 or SL 3 box separately, they can can also be purchased as packages. For example, a package with Scratch Live, two Serato Control Vinyl records and the Rane SL 1 box is usually priced at about USD $540.
Similar vinyl-based digital solutions are also offered by Stanton's Final Scratch, Native Instruments' Traktor Scratch, and Torq DJ.

But if you're just looking to get your feet wet without the need for expensive hardware, there are software-centric options to tickle your beat matching and vinyl scratching fancy. Here, instead of using digital vinyl, you'll be using your Mac's trackpad and some keyboard combinations to perform your mixing trickery. Of the paid-for options available, I've found algoriddim's Djay (USD $49.95) to offer the best balance of simplicity and ease-of-use for novices, as well as providing some advanced features for the more seasoned DJ.
Like a traditional DJ setup, DJay's interface presents dual virtual turntables to the user. Playing a song on one of the turntables is as simple as dragging and dropping songs from your song library (which is very nicely integrated with iTunes) to the desired turntable. Besides EQ, gain level, record speed and mixer controls, you can also set looping and cue points. To facilitate your workflow and mixing, the app features an "analyze library" feature that analyzes your songs and provides the beats per minute (BPM) of them. But if you're feeling lazy and not in the mixing mood, you can choose the app's "Automix" option. As implied in its name, the feature puts DJay on autopilot and automatically mixes your music for you. While DJay is suitable for use without any special hardware, Vestax has developed Spin, a USB controller that provides for more physical, turntable-like control. Spin is available at the Apple Store for USD $249.95.
Advances in technology have changed DJ'ing, as the sight of seeing DJs carrying in large carrying cases and milk crates full of 12" records has become less frequent. Serato and DJay represent two DJ'ing offerings available on the Mac, but by no means are they the only options. Readers, we'd like to hear some of your recommendations to the aspiring DJ or the mixmaster in all of us.

MacBook Pro 17-inch unibody review


There's not much that can be said about the 17-inch version of the MacBook Pro that hasn't already been said about the 15-incher (and to some extent, the MacBook). Still, the big, big brother of the family has a few key differences that make it stand out from the rest of the gang. The first being its non-removable battery, built out of tech which Apple claims will result in groundbreaking lengths between charges. The second difference, available only as an option, is a non-glossy display -- an addition which many have pined for since Apple's full throttle decision to move to extremely high-glare screens. Are these changes compelling enough to induce users to upgrade? Will previous 17-inch fans find a slam dunk or a dud underneath the unibody exterior? Read on for the full scoop.


There's no point in going as in-depth on this model of MacBook Pro as we did on the 15-inch version. In terms of hardware, build quality, and general patchwork inside, this is the same computer (albeit somewhat more gigantic). The same unibody construction is used here, and Apple calls the laptop the "world's thinnest and lightest 17-inch notebook." We won't argue -- it compares favorably to the smaller entry in the family, and besides it's obviously larger footprint, we didn't feel it was excessively heavy for a device of this size (it actually weighs 6.6 pounds, just a little over a pound heavier than the 15-inch version).



All of the other details, like the glass trackpad and new keyboards are completely intact. Actually, if you saw one of these from a distance, it might not be immediately obvious that it was the 17-incher (save for how tiny the human using it would look in comparison).

Hardware

The version we received was the fully kitted out iteration of the laptop. The base configuration (a not-super-cheap $2,799) is outfitted with a 2.66GHz CPU, 4GB of RAM, a 320GB hard drive, and the switchable NVIDIA GeForce 9400M / 9600M GT GPUs. The version we have came fully loaded with a 2.93GHz CPU, 8GB of RAM, a 256GB SSD, and (yes) an anti-glare display. Needless to say, performance wasn't much of an issue -- but the final cost ($4,899) might be a little extreme for most.

In terms of day to day tasks, this computer is simply overkill. If you're working on even somewhat graphically intensive projects, you can probably get by just fine with one of the smaller models. It's not as if the GPU is more super-charged than any other system in the line. The real advantage here is the massive screen real estate, matte display, and the supposedly gargantuan battery life. The 17-inchers do seem suited to those working in the video or photography fields, and Apple clearly isn't too interested in trying to shill these to the mainstream. The company is actually touting features like a 60 percent greater color gamut in the display panel (which incidentally is the same in both the gloss and non-gloss versions).





Performance on our system was insanely fast, though. From cold boot to active desktop took roughly 30 seconds, which is blazing (at least to us). Jumping from app to app, dealing with huge images / editing, multiple tabs of CPU intensive websites, and having scores of projects open at once didn't faze the Pro. The biggest performance gains were in disk access, and obviously the SSD is a major player here, but even general UI elements seemed snappier and more responsive than on our other computers. Of course, none of that should come as a surprise, this is -- after all -- Apple's top of the line laptop.

So let's talk about that display for a moment. Our biggest gripe about the other new unibody Macs was the lack of a matte option for the screens. In our review, we noted that the glare on the new LED displays is so intense that it's actually quite distracting in anything other than a lowly lit room. Apple chose to solve the problem on the bigger versions by introducing an anti-glare option (for an additional $50, of course). Interestingly, the company prefers the term "anti-glare" to "matte," which is odd, since "anti-glare" quite obviously suggests the other option is, well... "glare."


MacBook Pro 15-inch vs. MacBook Pro 17-inch

Regardless, the new display is stunning. Not only is the thing massive in terms of resolution (going back to the 15-incher made us feel like we were working on an OLPC XO), but the color depth and contrast are stunning. Apple seems to have really honed the art of light sensing, and we found the display accurately adjusting itself to a room's light. When cranked up to full brightness, the screen beams -- it's crisp, clear, and colors pop. We're not designers, and we're not professional photographers, but as far as we can tell, this display would be pure win for folks in those lines of work.



Of course, the big question on the hearts and minds of gadget fans everywhere is: does the battery deliver on Apple's promises? First, a little background.

As you likely know, the battery in the 17-incher is the non-removable type, much like the MacBook Air... with one major difference. Phil Schiller went on and on at Macworld this year about the lengths the company went to in developing a battery which is not only built into the system, but extends life far beyond that of a typical unit. The result was a The claim from Apple is that the 40 percent larger, lithium-polymer-based bricks they came up with can provide up to eight (yes, 8) hours of use on a single full charge, and can be re-juiced 1000 times before needing to be replaced. Once you need said replacement, the packs can be swapped out by Apple for a low, low fee of $179.

So, the claim: up to eight hours with the on-board graphics, and seven hours with the discrete GPU switched on -- how did they fare?



In our tests, under normal use (image editing, heavy web surfing, blogging all over the internet, YouTube / Viddler video watching, really serious AIM sessions), the laptop nabbed an average of 4:40 on a single charge with the low-power GPU, and, surprisingly, just under four hours (about 3:50) with the discrete chip. Those numbers fall right in line with other reviews we've seen of the laptop, and our feeling was that they're fairly consistent across the board. So, we're dealing almost four hours discrepancy with what Apple claims -- but what does that mean? According to the company, they tested a 2.66GHz model with the screen at half brightness while browsing the web over WiFi and editing a text document to achieve that eight hour number. We put the system to a more average and complete test, and frankly, we're impressed with the results. The new battery bests the typical lifespan of a MacBook Pro removable by almost double. Having seen what it's capable of, we could get comfortable with Apple adding batteries of this variety into other new laptops they produce, but let's revisit this again in a year or two -- we still have no idea what the long term experience would be like with one of these. Will it live up to the promise of a 1000 charges? We have our doubts.

Still, if we had to choose a swappable scenario over this, it would be hard to choose. From experience, being able to quickly swap to a new battery is a huge benefit when you're on the move and don't have a second to recharge. On the other hand, the huge stretches of time between charges we saw on the new 17-incher are extremely encouraging, and likely long enough to make the system viable for field use.

Wrap up

Ultimately, the decision about whether to buy the bigger MacBook Pro is probably already made -- if you're a power user who needs the real estate, there's little to deter you from making this purchase. Apple has cleaned up the design in all the right ways, improved the display and guts considerably, and proved that it can milk a substantial amount of time from a non-removable battery. The cost may still be a major barrier here for most, but something tells us if you really need a computer of this size, you'll find a way to pay for it. Our actual gripe comes not in the form of problems with this particular system, but in Apple's methodology of rolling out options for their laptops. Unlike competitors such as Dell, if you want a 15-inch Apple laptop, you're stuck with one type of display (the same resolution and same obnoxious glossy finish), and your options for other components aren't much better. Apple: you've proven that you can turn in a beautiful, clear LED display without resorting to the reflective sheen of the current models -- why not extend that kindness to the rest of your users?

Is The MacBook's New Super-Battery Actually Cutting Edge?

| posted by Chris Dannen

The best new feature in Apple's [AAPL] new MacBook Pro is the 8-hour, ultra-durable battery that Apple says it custom-designed. But is it really the advanced powerplant it claims to be?

Conventional notebook batteries, or lithium-ion batteries, are made up of tightly-packed cylindrical cells, almost like a bunch of little Duracell Cs in a case. Apple has chosen to use lithium-polymer batteries in the new MacBook Pro, which are widely regarded as more advanced than li-ion batteries; they're lighter, more physically robust, more energy-dense, cheaper to manufacture and don't have to be in the traditional block form-factor.

Macbook ProBecause li-poly batteries can be any shape, Apple smartly molded the new MacBook Pro's battery to the inside of its case, packing in a 40% "bigger" battery into the machine. That increase probably has as much to do with the physical size of the cells as the energy density of li-poly storage, which has helped Apple keep weight down. The MacBook Pro tips the scales at 6.6 pounds.

The new li-poly battery allows Apple to claim eight hours on a single charge, or seven with a beefier video card. Each battery should survive longer, too; Apple claims five years, or 200-300 full charges. That longevity owes itself to Apple's new "adaptive charging" system, which uses microchips inside the battery to determine the optimal level of current for each cell.

But put your ear to the ground in the battery community, and the buzz isn't about custom-shaped li-poly batteries, with or without "adaptive" charging. Companies like ZPower are already boasting huge improvements in silver-oxide batteries (also known as silver-zinc batteries), which have a much better energy-to-weight ratio than lithium-based batteries. You can see an animation of how silver-zinc batteries work here.

Not only are they 40% more energy-dense than lithium-based cells, silver-zinc batteries are 95% recyclable, and because they don't contain lithium, they're not prone to exploding and engulfing your precious notebook in flames. Apple's new li-poly battery, to its credit, is arsenic, BFR, mercury, and PVC free, and “highly recyclable,” according to the company -- but it's hard to beat silver for its green cred and safety.

The downside is that silver-based batteries are susceptible to the fluctuations of the price of silver, which has been on a rollercoaster ride since late 2005. [To see a graph of silver prices since 1992, courtesy of TheBullionDesk.com, click here.] That has rendered them useful only in small, if important, devices like the on-board computers inside self-guided weaponry.

But ZPower, for one, has said that it's gearing up to launch its batteries inside a "major notebook computer" this year, suggesting that some of the leakage problems that plagued early silver batteries has been solved. The company plans on using a trade-in recycling program to keep battery prices stable and manageable. California-based ZPower, whose backers include Intel [INTC], claims this will add two hours to the life of an average notebook battery, a jump from five hours to seven hours.

With its monster battery registering at welter-weight size, Apple is ahead of the pack for now. But should a competitor like Dell [DELL] or HP [HPQ] come out with a silver-ion battery in one of their 2009-2010 notebooks -- and should the price of silver fall -- all of Apple's custom in-house engineering might have been for naught.

Apple unveils all-new 17-inch MacBook Pro


Apple just confirmed the totally expected yet eagerly anticipated unibody 17-inch MacBook Pro. They're calling it the world's thinnest and lightest 17-inch laptop. It features a 1900 x 1200 LED backlit display, with a 700:1 contrast ratio, wider color gamut and a glorious $50 matte option. Most of the specs are otherwise quite similar to the 15-inch MacBook Pro, but unfortunately Apple went with a MBA-style non-removable battery, claiming that the lack of removable mechanism allowed for more battery -- they're speccing it at 8 hours of lithium polymer juice on integrated graphics, 7 hours on discrete, and it's rated at 1000 recharges. There will also be an exchange program, like with the iPod. The base model hits at $2799, spec breakdown and more shots after the break.
