Emagic Logic Platinum 6

Mix magazine reviews Emagic Logic Audio Platinum Version 6, testing new audio recording, mixing and MIDI sequencing features in Logic Audio software.

About a year ago, Emagic surprised the audio industry with its
announcement that it had been acquired by Apple. Everyone waited to see
what the implications would be for the Logic series. We didn’t have to
wait long: Emagic introduced Logic Platinum 5.4 for Apple’s OS X last
fall, boasting the first pro audio host program to support Audio Units.
Recently, I took a look at Logic Platinum 6, the long-awaited upgrade
of what many would argue is one of the most powerful and versatile
sequencing/audio software packages available today. Because OS X is
still relatively new to our industry, this review focuses on ways Logic
harnesses the features of this powerful operating system, as well as
the numerous upgrades in Version 6.


OS X introduced us to Core Audio, which handles audio at the system
level. Whether you’re using a PCI-bus audio card or a USB or FireWire
solution, audio is handled more efficiently and latency is kept to an
absolute minimum. Audio and MIDI both have highest priority in the
system, which was certainly not the case in prior versions. With the
Core Audio HAL (Hardware Abstraction Layer), the latency between
applications and I/O hardware is exceedingly low; as low as a virtually
indiscernible 1 ms with certain hardware. Also, multichannel audio is
now handled internally, a step up from the former limitation to stereo
in all pre-OS X operating systems. The audio resolution is 24-bit/96
kHz, with 32-bit internal processing. Core Audio also allows multiple
applications access to multiple interfaces simultaneously.

Another major upgrade with OS X is in MIDI handling. OS X is the
first Apple operating system that literally integrates MIDI at the OS
level, and the system is referred to as Core MIDI. No longer are
third-party MIDI drivers like OMS required. An Audio MIDI Setup
application allows the user to create a global MIDI configuration that
can be used by all applications that need it. Because MIDI happens at
the system level, it is much faster and more efficient, minimizing
latency in the same fashion as Core Audio.


Probably the most exciting new feature in OS X is Audio Units, the
new plug-in architecture that exists at the system level. Along with
myriad other benefits, AU allows a user to use a plug-in in multiple
applications simultaneously. This is the stuff of dreams. Among other
positives here is the documentation included, both for plug-in
developers and, more importantly, host developers. And while there are
no guarantees that the various plug-in developers will abandon the idea
of proprietary plug-in formats, one begins to get the idea that, at the
very least, they will make AU versions of their plug-ins available. By
virtue of the enhanced GUI capabilities and exceedingly versatile and
powerful development tools available, plug-in developers would be crazy
to pass on Audio Units.

AU is a landmark system that was developed with a very healthy
influence from the worldwide community of home-based and commercial
plug-in developers; there is a strong sense of global
“community” when it comes to AU.

Although Logic 6 runs very well under both OS 9.x and OS X, VST
plug-ins are only supported in the pre-OS X operating systems; only AU
plug-ins are available in OS X. So, ostensibly, you must make a choice.
But there’s good news about this problem: An organization in the UK
called FXpansion has developed an application that actually takes any
carbonized VST plug-in and creates a derivative plug-in that works in
AU. Strictly speaking, it’s not a wrapper because it actually creates a
new plug-in. The new plug-in is part AU, part VST, but works perfectly
under AU. The hit to your CPU is thus minimized (typically less than
0.1% per instance!). This allows all of your classic old VST plug-ins
and instruments to be resurrected. This is something that almost had to
happen, because we’ve all grown so accustomed to our favorite


The coolest new feature is Freeze. As with any other host-based
application, the CPU can be overtaxed enough to render the applications
unusable with even modest real-time DSP and even more so with virtual
instruments. Freeze eliminates this problem.

Although an elegant solution, it’s really nothing new. It’s one of
those smack-yourself-in-the-forehead, “Why didn’t I think of
that?” situations. But while the idea for the solution is simple,
the execution is not. And that’s its brilliance. Read on and see

Most DAW users have realized for a long time that when a virtual
instrument with one or two plug-ins gobbles up huge amounts of CPU
resources, you render the track by bouncing; as a result, the CPU only
needs to handle playback, leaving much more power available for further
programming and mixing. Freeze makes this process virtually
transparent. Rather than going through all of the motions —
creating buses, muting, selecting, bouncing, importing and so forth
— you simply indicate which tracks you wish to
“freeze” by pressing a global Freeze button. During the
next occurrence of playback, Logic very quickly renders the tracks with
all automation and plug-ins in place. The frozen stereo audio tracks
have a default resolution of 32 bits. You can choose any other
resolution you like, and this is a nice, tidy way to render files for
export. The unwieldy process of rendering individual tracks one after
another becomes almost mindless.

Obviously, it is preferable to avoid committing to the EQ, dynamics
and whatever other DSP you have in place, and you certainly don’t want
to do so permanently. Or if you wish to transpose the key or otherwise
alter your MIDI programming for a virtual instrument, you must have the
ability to revert, which was an unwieldy and downright difficult
process prior to Freeze. Because the frozen audio file is a
representation in Logic 6, it is just as easy to
“unfreeze.” Then you can modify to your heart’s content and
“refreeze” if you care to do so. This is all done with
maximum transparency. Emagic touts this process as “CPU
management,” and it is truly a brilliant way to maximize CPU use.
The idea is not revolutionary, but the simplicity of its execution is.
Emagic, as usual, lives up to its name.


Emagic has also gone to some lengths to make Logic 6 more
user-friendly and shift some of the focus away from the operational and
toward the creative aspects. For instance, there is an elegant
mechanism to hide/expose tracks now that will be intuitive to seasoned
Logic users, but simple for new users as well. There’s also the
powerful new Marquee tool, which enables “region and
sequence-independent selection and editing.” For example, I was
able to select across the boundaries of a repeated loop, which had the
effect of creating a representation of a new loop. This is possible
using Smart Loop Handling, which prevents any ill effect to copies or
aliases while, for instance, the user is working with the Scissors
tool. In my example, a copy of the new loop was created, and when I
moved it to another track, it became an entity unto itself. In
addition, the Smart Snap feature behaves exactly as the name implies:
Objects snap into position dependent upon a chosen level of resolution,
causing the mouse to be smoother and more intuitive.

Another welcome new addition to Logic 6 is editing at near-sample
level in the Arrange window. Editing at this level of resolution was
previously only available in the sample editor. This is one of the few
new features that makes Logic 6 feel a bit more like Pro Tools. Another
perk is the ability to have a thumbnail of a movie displayed
frame-by-frame in the Arrange window via QuickTime. The level of zoom
automatically determines the number of frames displayed. You can also
find a setting for this feature in the video preferences. Another
powerful feature associated with video synchronization is the ability
to import or export DV via FireWire into and out of Logic directly.
It’s a nice way to get your movie up on a big screen in your mix
environment. Another major step forward is the capability to
time-stretch directly from the Arrange window. This speeds up the work
process immensely.

One of the most significant upgrades in Logic’s operation is in
grouping: Every channel can be assigned to one or more of a maximum of
32 groups. The groups can be for editing, mixing or both. Grouping like
this is nothing new, but now that it’s finally available in Logic,
users will enjoy the ability to create drum muting, vocal mix groups
and so forth. Users can group tracks vis-à-vis zooming,
hiding/exposing and record-arming, among other things. Individual sends
can be grouped per track, as well.


Logic now supports quite a number of third-party control surfaces.
While the Logic Controller has been, and probably remains, the best
choice if you already have other controllers at your disposal, it’s
nice to be able to use them all. A powerful feature of this support is
that you can simultaneously use any number of controllers from
different manufacturers configured as you see fit. Another powerful
aspect is the ability to assign controllers literally. For example, one
can use the linear faders of a pair of controllers in a
“long-throw/short-throw” configuration, like a large-format
analog console. The possibilities are wide open. Controller
configuration is accomplished outside of the Logic
“environment,” existing in a state that is probably best
described as a plug-in. Each different brand and model has a
“plug-in” associated with it, and you can have multiple
iterations of each.

Other clever additions include the Mix in Arrange feature, which
gives you a mix module or “channel strip” in the parameter
section of the Arrange window. The display automatically coincides with
a channel selection. It’s great to be able to tweak mix parameters
without switching to the mix display. Also available is a powerful EQ
plug-in available for each channel. It features eight bands, including
filters and shelving — high and low — and four parametric
bands in the middle. However, all eight bands are fully parametric;
they simply default to the above-described configuration. The GUI for
this EQ provides a wealth of visual information about the EQ curve.
There is a nice representation of that curve on each channel strip in
the Mix window. Aside from all of the EQ’s nice visual aspects, it
sounds good, too — really good.

For users of Propellerhead applications such as Reason, ReWire II
support is a welcome addition to Logic 6. Up to 64 channels of audio
can be routed from that application into Logic, and Logic’s MIDI
sequencing can control virtual instruments going back the other way.
Synchronization between the two applications is a breeze.

Logic now features a Project Manager application, which allows handy
consolidation of all the resources associated with a project in one
place. It enables renaming, introduction and editing of comments.
Another powerful tool here is “Save As Project,” which
enables simplified archiving and transport another way. It consolidates
all aspects of a project, even the audio used by samplers. It yields a
panoply of options in terms of how and what is saved: a great way to
organize and prepare a project for transport to another studio or


There is a reason why there was a slight delay between the
acquisition of Emagic by Apple and the appearance of an expected
product upgrade. They wanted to do the upgrade correctly, and they
succeeded. It’s powerful and supports almost every format you can
imagine. Seasoned users will be thrilled with the powerful new tool,
and newcomers will be bowled over by the possibilities. Logic 6 will be
a serious application used by professionals in all different production
