Why does so much of their response sound like a combination of snake oil
and monster-cable fallacy talk to me? Re-install Independence? Really? I
get the high-performance setting and USB 3.0 port and USB 2.0 device
thing, also the thou-shalt-dedicate-a-USB-2.0-port-to-thine-interface
thing. But short cables? Special ones? Is there something about how
electrons travel over wire that I've forgotten in fifty years? I mean,
we're not talking about any kind of power transfer here, so how could a
No. 30 versus a No. 24, or maybe 22, data cable make that much of a
difference?
Charging the line inputs symmetrically? Does that mean making sure they
are in phase or something? What on earth would that have to do with
running a softsynth through said audio interface?
And did they really mention codemeter? Is that thing really still in use?
Can't wait for you to test this, Pete.

After putting in my support request to Magix, they finally got back to me after several weeks with a very helpful reply that I thought might be of interest to others on this list. I am just getting around to working through this (and other e-mail) after returning from our recent trip around Colorado.
Anyway, this relates to the drop out problems I was seeing with the Independence instruments. There were three main points of advice that Magix gives in their reply (copied below my signature below). I’ll summarize the major points here if you don’t want to read through the whole thing and think you might need to tune up your system:
1. They suggested changing to the “High Performance” Power Plan in
Windows and making a number of modifications.
2. They also had a number of very specific suggestions about
configuring USB 3.0 devices. Since I’m using a firewire device
(the Saffire Pro), this isn’t my problem, but these suggestions
might help others.
3. They also suggested turning off “Core Parking”. This is a feature
that turns off cores that aren’t being used in the CPU when there
isn’t a high load on the system. Apparently there can be a lag
time when turning on these cores when the demand gets high.
Anyway, read the note below if you want more details on how to tweak your system if you are having similar problems. I still need to get a chance to test some of this out in Samplitude. Hopefully in the next few days (although our daughter will be visiting then so it might have to wait a bit longer still!).

The USB environment must be right!
1.
To make sure everything runs smoothly, you have to pay attention in
advance: It is a USB 2.0 interface, which in principle claims a USB 2.0
controller on its own due to the high data rate required. No
matter how many ports the computer makes available, if only an extended
USB host is displayed in the Device Manager, you should not use any
other 2.0 devices (extra hard drive etc.) parallel to the USB
AudioInterface. Where the 1.1 devices are connected (for example, the codemeter), one must also work out, so that the bus is not braked. Therefore,
our tip is: Spend your computer for a few euros a second USB 2.0
controller (as a PCI or PCMCIA card), where then only the USB audio
interface is operated. Then
you have to pay attention to high-quality cables, the included USB
cables are often very short, in most cases, you will want to have the
USB device near the mixer, but for me a cheap Thomann USB extension made
everything go awry, a solid one , long USB cable did but then his service. In
addition, it is worth charging the line inputs symmetrically when the
outputs of the mixer or other sound sources give that, the investment in
appropriate cable is worthwhile. When everything is properly wired and installed, working with the USB audio device is pure joy.
2. You may not use a USB 3 interface! Some older audio interfaces have problems with it.

Core Parking
Core Parking is a sleep state, C6, supported by most modern processors and Operating Systems.
Core Parking dynamically disables CPU cores in an effort to conserve power when idle.
Disabled cores are re-enabled as the CPU load increases once again.
This technology is very similar to frequency scaling, in that it seeks to throttle the CPU when idle.
he problem is that Window’s default power profiles are configured far too aggressively when it comes to core parking, especially on workstations. Their interest was in conserving energy, even if this meant marginally decreasing performance.
A number of complex parameters control when a core should be parked, and Microsoft tuned heavily
towards power savings. BTW, to deal with this issue, Intel changed Skylake to manage it’s own CPU core parking. Read more here… <https://bitsum.com/product-update/intels-speed-shift-validates-parkcontrol-and-process-lasso/>
The core parking settings in Windows are implemented as parameters of power plans (aka power profiles). That means you can, for example, disable core parking for the High Performance power plan, but
leave it enabled for other plans. And that is exactly the desired tweak for most users: disable parking only for high performance power plans.
Efficacy
Empirical evidence shows that disabling core parking can make a real difference in system performance. There are many factors that will determine how efficacious it will be for any given system, including the
CPU type, application load, and user behavior. However, we find that Windows is often over-aggressive in its core parking, resulting in excess latency as cores are unparked to accommodate bursting loads (the
most common type of CPU load).
In our tests, we’ve found AMD processors benefit most from disabling core parking. This is perhaps due to the dramatic difference in the way AMD processors share (hardware) computational resources between logical
cores. Microsoft optimized for Intel’s Hyper-Threading, which has much less capable secondary cores. AMD’s secondary logical cores are near full CPUs.

I have been experiencing audio dropouts and/or glitches when using instruments
from the Independence Pro Library and wonder if this is a known problem or if you
have any suggestions (or an update) for fixing this.
To verify the problem and narrow it down to Independence Instruements, here is the
experiments I ran:
1. I created a new project in Sampllitude with one of the FM Rhodes instruments
from the Independence Library on one track and Ivory Piano on a second track in
the same project.
2. On the track containing the Independence instrument I played and held down a
triad of notes (e.g., F-A-C) and held the chord for a measure or so or until the
sound had nearly A(but not quite) decayed. I then hit the triad of notes and held
it again. I kept repeating this until I heard an audio dropout or stutter.
3. When playing the Independence instrument I would generally hear a dropout or
stutter after about 25-50 measures.
4. I then repeated the experiment by doing the same thing on the track with the
Ivory Piano – i.e., I hit and held a triad of notes, hit the triad again after the
sound had nearly decayed, and repeated the process.
5. When playing the Ivory Piano I never heard an audio dropout, stutter, or
glitch and could play rock solid for over 100 measures.
6. I also repeated the above experiment by substituting one of the instruments
from Dimension Pro 64-bit (which came with Sonar Producer) for the Ivory Piano and
using various other pianos from the Independence Library. Again, within the same
project, the instruments from Independence always caused an audio dropout within
about 25-50 bars while the instruments from Dimension Pro were rock solid and I
never heard an audio dropout or glitch.
I’ve also varied the buffer settings in Samplitude from min to max, varied the
ASIO buffer settings for my Saffire Pro 40 fire-wire connected audio device,
turned off as many background processes on my PC as I could and observed that none
of the changes made any difference to the frequency or nature of the audio
dropouts observed with the Independence instruments.
My computer is a very new Windows 10 64-bit system with an i770 CPU, 16 GB of RAM,
and an SSD, so I don’t think that is the problem. I also did a separate
experiment in which I ran the Independence instruments from an ordinary hard drive
on my system and then copied the Independence Library to my SSD, but that did not
make any difference to the frequency or nature of the problem with the
Independence instruments.
I have the latest build of Samplitude X3 Pro.
Thanks for any suggestions (or a fix!).
