Ext USB interface... adobe 3.0 still lags and drops

It's killing me!
I have a brand new laptop, with Vista, 4GB ram, (average sound card, I know) with and new External USB sound card/interface (tascam to be exact).
However, even after recording a couple of tracks, no more than 30 seconds long, adobe starts lagging and dropping - making recording useless - as im sure a lot of you know.
Whats the best way to fix this? I thought by buying an Ext USB, I could get rid of the lag/drops etc...
Thank you,
danny

It's probably not the laptop itself, but all the background processes that are running on it. First thing to do is turn off the wireless adapter (with a switch, if the laptop has one) while you are doing any audio work as this can cause spikes in DPC latency. You can get a tool to check for DPC latency here.
If you do a search for "tweak Vista for audio use", you will come up with a number of hits, including this one from Audio Forums. Once you have gotten rid of some of the crap off the machine, I bet you have a lot better luck.....

Mac book air connects to internet w/ lag and drops

my macbook air has been working for the past year, but recently my internet has been lagging and disconnecting by itself every 30 seconds. all my computers connect through a router and modem but only the mac air is having internet problems. it keeps saying "the page cannot be displayed" even though airport shows that it is connected to the internet. (note: the mac air works flawlessly when I connect to other wifi locations outside of home)
router: netgear
all the things I've tried.
-editing keychain settings
-deleting my network and creating a new one
-resetting modem and router
-resetting airport
-changing dns and ip settings
-resetting the mac air
-turning off bluetooth
-changing browser settings
-smashing the router around
nothing has worked....
p.s. there was one day where I changed my router and it worked for one day, the next day it didn't work again.

What are your wireless encryption settings? WEP, WPA2? Have you tried it with no encryption? Was it faster? Sometimes if you have rearranged the room or moved the router, interference can start. I also would download istumbler and see if you have neighbors using the same or adjacent channels. It will also show you the noise on your Netgear. Maybe this will bring some ideas to you:

Mac os x yosemite 10.10.1 still lags and bugs while using macbook pro retina 13inch i5 mid 2014

i just got macbook pro retina and i upgraded to yosemite 10.10.1 its still have bugs and lags a lot , does anybody feel the same ,
its not smooth at all ..

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
How to Clean Install OS X Yosemite
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Has the new Early 2013 Retina Macbook Pro still lag and display issues?

Hello. I've never had a Mac before and I'm thinking of buying the new "early 2013" 15-inch (2.7 Ghz, 16Gb Ram, $2799) Retina Macbook Pro. I live in Argentina but I'm going to NYC in a couple of weeks and I want to get one there. The thing is, that I can not be returning it 2 or 3 times like I read a lot of peple had to, because I'll be coming back home after 2 weeks and here they will only fix it, not replace it for a new one, and that could take months.
So, I want to know if you guys can help me decide if I should go for it or not, if these image retention and burn in and ui lag issues appear to be fixed with this new model or if it is still the same. If I don't buy this one I'll be getting the new Samsung Series 7 Chronos they showed in CES 2013, still not available in the market. Thanks a lot!

I just checked and I have the LG SJA2, too. I didn't notice any Image retention at first, I tested it with the chessboard test for 5 or 6 minutes, it showed no IR. But with 10 minutes I can see a bit of IR. Nothing that can affect the normal use of the computer, I mean I have to put the chessboard for 10 minutes and then change to grey to notice it, but it does exist and is the SJA2 from LG. If it doesn't get worst, I think it doesn't even matter. I just hope it doesn't get worst.
FWIW, I noticed that until I stopped looking at the chessboard before it switched; my eyes had image retention. But in that awfully long thread on the subject, some have insisted that if it's an LG, it's trouble so I guess there's no guarantee. (BTW, I was writing this when you tried the test again - ocular image retention?)
Not to hijack the thread, but shortly after I posted that "good news" about SJA2, my rMBP simply refused to start at all; it was totally inert. Charging, not charging, SMC reset, nothing helped. Tech support's only solution was bring it in to be fixed.
On a hunch, and remembering something about magnets in the top of the display activating a reed switch in the base, probably near the trackpad, I lifted the front of the Mac about 1/4" inch and let it drop. Bingo! The Mac has operated properly so far. I suspect the reed switch was stuck in the wrong position, and some evidence suggests it was that way out of the box and my fix corrected it.

In iTunes when I press "add to" playlist I get an error message, but I can still drag and drop the song into a playlist

Why is this happening and how can I resolve it?

I called Apple Support and they walked me through it. They told me to basically copy and paste my music to the external hard drive. (I think.) Or maybe it was they had me transfer a folder to the EHD. I don't exactally remember it was a few years back. But I tried to plug in the EHD before starting and...nothing. Still says same thing, "locate file."

WRT120N Lag and Dropping Connection

I have an internet connection of the speed of 384 kbps, settings are default i changed nothing. firmware is updated. i'm using wireless connection.

Audiobox usb interface won't mount on MacBook Air

PreSonus AudioBox USB (2in/4out) when attached to either USB on mid 2013 MacBook Air 11, won't show up in garage band, garage band preferences, apple audio system preferences, apple midi system preferences or even in the 'about this mac' system report. The device is totally unrecognized and supposed to be totally compliant plug and play. I'm runnin OS 10.9.1 with all updates. The AudioBox interface shows red power light and a light on the 48V phantom power button. All cables are good, Microphone functions and MacBook air is connected to a power supply. (Macbook, condenser microphone, AudioBox and all cables are new.) Any experience with this out there?

Yes, Id return it and either:
get the Roland UA-22 Duo-Capture EX
or the Focusrite Scarlett 2i2 USB
WHAT mic?
The best idea is to drop that noisy and hissy squawk box and get a ZOOM H6 which has USB interface with MORE options, LESS noise, and far easier to use
phantom power from the H6 is from 4 AA batts, and not via USB. (have and use same myself) with these Mics:
The unit youre using is getting 48V phantom via USB, which depending on the Mic, often stinks.

Adobe Captivate Help | Drag-and-drop interaction (for subscription and Adobe Software Assurance customers only)

This question was posted in response to the following article: http://helpx.adobe.com/captivate/using/drag-and-drop-interaction.html

Yep. But it will only likely get to you in the next version released for NON subscription or ASA customers. With 6.1 Adobe was giving a preview of the functionality they would be including in your next release. Either way, whether you upgraded to the subscription edition or waited for the next paid upgrade, you were always going to be paying something to get this new functionality. 6.1 users just got it earlier than everyone else. That was Adobe's decision. It certainly hasn't been a popular one.

PLEASE HELP!!!!!!!!!!! ADOBE SHOCKWAVE SLOW, Lagging, and I NEED URGENT HELP!!

Hello everybody, and how are you all doing on this wonderful Friday?
Today after doing research on the support website for Adobe ShockWave flash player, I'm here as a last resourt.
Allow me to explain the issue!
WARNING:
THIS IS GOING TO BE EXTREMELY LONG, BUT I NEED HELP VERY VERY BADLY!!
I've waisted people's time because of this issue.
I'm using an HP Windows 7 Laptop with latest version of Windows 7!
I have Adobe ShockWave 11.7 the LATEST VERSION and It is a great program.
However in one of my simulators which is a V500 Evita Ventilator simulator from the company Drager, the performance is HORRID, and when I say horrid, I mean HORRID TIMES 30 and then some.
Keep in mind that this has been tested by the company on other computers, and it works just fine, however on mine the waveforms and data is choppy, slow and what it will do is it will be working smoothly one second, the next second It lags and then catches up, then lags again, and It basically drags along miserably. I used this program online and then when I contacted Drager the owners of the simulator, they thought I get a DVD of the simulator. THEY GAVE IT TO ME FREE OF CHARGE. I got it, and It was still slow and Jerky. I had used Google Chrome to use the simulator online HOWEVER, when I used the DVD, It was still slow. I have a LOAD of computer space, and have tried uninstalling Adobe Shockwave, Reinstalling it, then doing that several times. NOTHING. NOW WHAT??
I'm desperate right now. When I say DESPERATE, THIS HAS GOT TO BE FIXED AS SOON AS POSSIBLY POSSIBLE.
ASAPP!!!!!!!!!!!!!!!
Is there some setting I can adjust?
Or SOMETHING???
The thing is other things that require Adobe Shockwave work just fine. I use a lot of simulators.
Its just this simulator.
PLEASE RESPOND!!
THANK YOU, and God bless.

USB Interface Not Working With Logic Pro 9

Hello,
I've had a Tascam US-1641 for several years now with absolutely zero issues on my old PC. Ever since I upgraded to Mac (early 2011 17 inch Macbook Pro running Snow Leopard) I've had nothing but problems with the US-1641. No matter how many times I uninstall-reinstall the drivers and what USB port I plug it into, whenever I turn on the device and it's connected to my Macbook, it crashes my operating system and it freezes everything I was doing. Logic Pro doesn't load and when it sometimes does (10 minutes later), it immediately crashes when I click anything.
I've tried several tips to fix it and nothing worked. The most popular choice was select the default input/output in Logic to the system audio, then quit Logic, turn on the interface, then restart Logic. No such luck. I have to reboot my machine at least 5 times, uninstall/reinstall the driver and hope it works to use the interface. I thought it was the operating system, so I upgraded to Mountain Lion and installed the new driver for Mountain Lion, after of course deleting the other drivers and removing all previous data, and it is still giving me the same problems.
I don't have the money to afford a replacement model or a different interface from a different company, so I'm hoping you guys can help me figure out what exactly it is that's causing the interface to freeze my operating system and crashing my Mac whenever I try to use it. I am getting extremely frustrated at this and as much as I love OSX and Logic, what good is this piece of software if I can't use it? I need help.
Thank you.

The problem lies with Tascam and their inability to write stable drivers for OS X... and isn't anything to do with Logic Pro ..
As you know, you are not the only person to have had this issue and the reality is, while the 1641 might work fine with Windows, when it comes to OS X Macs.. it's an entirely different story... depending on the version of OS XS you are running.
The one tip I have read, that seemed to fix it for most people.. (Though not all) is as follows;
(Thanks to Paulypaulpaul for this)
-uninstall your tascam driver 2.10
-restart
-install driver 1.03
-restart
-plug in your tascam
-goto where you download your drivers (http://tascam.com/product/us-1641/downloads/), scroll down to the bottom where it says firmware, Download the firmware 1.02 (3rd from top under firmware), install it. your control panal should now read 1.03 for your drivers and 1.02 for your firmware.
-install drivers 2.10
-restart
Follow each of the steps exactly.. including all restarts when indicated..
...and good luck...

Clicks and popping with recording and USB interface-HELP!!!

I've submitted this twice, got some responses, but has twice been ignored into oblivion. I apologize for the reposts, but this is VERY IMPORTANT, and I've been struggling with this issue for MONTHS now dealing with countless hours of lost time trying to fix it to no avail.
I'll try to include as much detail as possible.
I use:
MacPro 2 x 2.66 Dual-Core Intel Xeon
3 GB memory
Logic Express 8.0.2
245.13 GB empty space on Hard Drive
THE PROBLEM:
When I record, I get computerized clips/pops
http://www.moogiex.com/clickpop.mp3
http://www.moogiex.com/morecackling.mp3
I record via a PreSonus Audiobox USB. This problem did NOT start when I got the AudioBox, but several months after.
When I simply monitor the sound going through the box, the sound is fine.It's something between the Box, and the computer output. My guess is some incompatibility with Logic Express or Core Audio and the AudioBox.
It is NOT the microphone or the cable (the pops occur with anything going in, 1/4", XLR, different inputs).
The clicks START with Logic Express. If there are any recording program open when Logic Express is open, and I record, I get the SAME pops.
It did this both under 10.5.6, 10.5.7, and now 10.5.8.
It is NOT clipping.
When I'm recording with LE:
—There's 1.27 GB of FREE Memory while I'm recording.
—Logic Express is only using 6.7% of CPU while recording (of only one of the four processors), and about 90-95% of CPU space is free on all four processors.
—This happens on ANY audio input, and it doesn't matter how many other tracks, how long it is. I just started a brand new file and it does it.
—This happens when I use ANY input into my computer, but is STARTED by LE.
Here are my Logic Preferences
Core Audio- ENABLED
System Memory Requirement 66.0 MB
Device: AudioBox USB
I/O Buffer Size: 1024
I/O Safety Buffer- UNchecked
Recording Delay: 0 samples
Universal Track Mode- CHECKED
24 Bit Recording- CHECKED
Software Monitoring- CHECKED
Independent Monitoring Level- Checked
Process Buffer Range: Large
ReWire Behavior: Live Mode (Higher CPU Load)
Maximum Scrub Speed: Normal
Scrub Response: Normal
There is *no* driver with PreSonus' AudioBox. It is simply "compatible." Here's what System Profiler says:
AudioBox USB (plugged into my Mac Pro's front bottom port):
Product ID: 0x0301
Vendor ID: 0x194f
Version: 1.08
Speed: Up to 12 Mb/sec
Manufacturer: PreSonus Audio
Location ID: 0x00200000
Current Available (mA): 500
Current Required (mA): 500
Here's what I've tried:
—Disabling CoreAudio, shutting LE 8 off, restarting LE 8, enabling CoreAudio again. This worked ONCE. It hasn't worked since.
—Disabling CoreAudio, shutting LE 8 off, SHUTTING DOWN, RESTARTING, opening LE 8, enabling CoreAudio again. This also worked ONCE. It hasn't worked since.
—"CPU Saving Mode"
—I/O Buffer to 256, 512, and 1024 (default) (IMPORTANT?—speed of popping actually INCREASES with larger buffer?)
—I/O Safety Buffer checked and unchecked
—Changing Recording Delay samples
—Pretty much fiddling with any of the controls
—Disabling Airport does nothing (was previously working fine with Airport running)
—Quit all applications, open up QuickTime (pro) or Audacity, and record something. It records perfectly. I go back to LE and the clicks and pops are gone, but only until I use anything with effects, then the clicks and pops return. This works SOMETIMES.
—Reset the preferences, and that has worked ONCE, and then the clicks and pops came back (albeit not as prominent, but they were still there).
—I trashed all files related to Logic and reinstalled. Worked ONCE.
—Restarting does help, but only temporarily, as soon as any pull is put on Logic, the problems return.
—Using a different USB port. I thought this was the solution because the problem shortly went away with regular use of Logic, but problem came back.
—Uninstalling Logic, Reinstalling Logic Express, same deal.
PLEASE, PLEASE, PLEASE HELP. I have a lot of money sunk into all this equipment that's practically useless with this recording issue.

Man, I feel for you on this.
I would love to see what your pops and clicks look like in your waveform. If you can take a snapshot of it and post the pic here that might help the diagnosis.
Your audio files certainly SOUNDS like you have a clocking problem. It really sounds like your CoreAudio driver/MacPro and your USB interface are not locked up in sync - as in: which is master and which is slave? I know some interfaces include a software control panel that allows you to set the status of the interface clock to slave to the computer or to be the master. It sounds like yours doesn't come with drivers but is there any control panel for this Presonus device?
Another place to check is in Applications>Utilities>Audio Midi Setup
On the left under "Properties for <your interface>" what does it say for the clock source?
Also in this panel, to the right it should have a button for "configure device". What happens when you click it? For example in my case it automatically launches my Apogee Duet Maestro control panel. In your case it might launch something similar, although I think you mention that you never installed anything, which I find strange to begin with - that this thing should just work out of the box with no driver at all.
I've struggle with w similar problem with my Apogee Duet, although nothing of this magnitude, maybe 4 or 5 clicks per 3 minutes of audio and these turn out to always be sample drops where 5-10 samples in a row are all the same in the waveform, as if my interface and computer stopped talking for a milli second. I did find that if my Apogee Duet was chosen as the default or system output in the Audio Midi Control Panel I mentioned above then the clicking was more frequent, as if choosing the audio interface for any system output caused a conflict with choosing it for Logic. I thought this was strange but you might want to investigate that further too.
At any rate, it does sound like a digital clock syncing issue to me by the sound of your audio. What effect does changing the sample rate of the recording have on the problem?
Let me know if any of this leads to anything.

Help with midi/usb interface and Logic 8

Hi there,
So here is the 'goal'
I have a SoftStep (MIDI USB interface) running into Logic 8 or Mainstage - my ideal scenario would be to pre-load various loops, clicks and Ambient Pads into Logic - these are usually in MP3 format.
Ideally, I would then be able to assign various buttons on the MIDI footpedal to start, stop and cycle through the various files.
Is this possible, and if so, how would I go about setting this up?
Many thanks in advance for your help.
T

he driver is indeed a universal version.
Cool.
I doubt it's the MIDI interface simply because when I used it to connect a Roland Juno-D to the computer, it worked perfectly fine.
Ok, cool. Rules that out
Notes get ''stuck'' on the visual keyboard, some notes are still considered 'pressed' until I press them again. There aren't many but it's worth noting.
Is it always the same notes? For instance, if C3 will never give a note off, it might indicate a problem with the actual keyboard mechanism in the piano.
ANYWAYS, when I've placed a monitor inside the environment at the places you mentioned, I can indeed see those odd low notes.
So it seems like the piano is sending low notes as you play the keyboard...
So I see this is a pretty solid visualize representation of what I thought was wrong. Note the C-2 is lower than I can even reach on my standard sized piano (my lowest note is A-1).
It certainly seems as though the piano is sending spurious MIDI data, as I mentioned, it might be the actual physical keyboard mechanism is mistriggering. From the things you've tried, it certainly sems to be the actual piano that's playing up, and not the MIDI interface or computer.
At this stage, I'd probably try playing around with the piano's MIDI settings, trying a reset procedure if it has one. It might be something as simple as dirt and crud in the keyboard causing mistriggering.
While you could use the environment to filter out those C-2 notes, it's not really going to help if the piano is missing note offs and triggering wrong notes. It might, as you initially suspected, be knackered...

USB interface to composite video and audio

I've been searching a long time for a compatible, low cost and convenient capture device for composite video and audio. The EasyCap devices are super cheap, but their audio section is just horrid. Others won't provide audio usable by Adobe Connect. The EZCap 116 seems to work very well with Adobe Connect, providing a single USB cable connection that carries both audio and video. To get it to work with Skype you need to use Splitcam. the only reminaing annoyance is that you have to use the bundled software each time you want to get the device to use composite or S-video inputs. Sure wish the Flash module would let you configure webcam settings directly.
My main application for the gadget is to interface our institutional VC codecs (which have VCR outputs) to Adobe Connect users.

Studio X: Doh!, you beat me, with your maximally cryptic reply!

Stereo to multichannel USB interface

Hello, I'm having a bit of a problem with my sound.
I bought a Hercules Gamesurround MUSE Pocket LT, a USb interface for 5.1 audio.
I've got it working with 5.1 games and movies but I'd like to output iTunes to all of the channels (so not real 5.1, but just fake it) as well as all other applications that output sound.
At this point I wouldn't even care if I lost the 5.1 surround, I only want to have the music coming out of all of the six speakers. I've used splitters in the past but for now that's a no go. It's a long story.
SO are there any drivers that output stereo to 5.1/multichannel ?
I've tried "USB Audio ASIO driver" but it only puts a beep every few seconds on the output and still uses only 2 speakers.

YAY!!!!
together with AULab from Apple, soundflower can set up stereo->surround audio.

It's taken me quite some time to figure this out, and considering how easy it was I should have gotten this done a long time ago. For a little bit of history, I purchased a X-Fi Surround 5.1 for my Macbook Pro. Anyone who has this sound card knows that it has wonderful audio quality, or at least in Windows. In Mac, it has no ability to upscale stereo sound to 5.1, which is something I really enjoy. I have this device connected analog out to 5.1 speakers, and here's how I got it all to work! I'm using OSX 10.4, and the instructions should be similar for 10.5.
1.
Download SoundFlower
http://code.google.com/p/soundflower/
2.
Make sure you have AULabs installed. It's part of the Dev Pack, so check
Developer/Applications/Audio for the AULabs
3.
Now we need to make sure that OSX knows that you're dealing with surround sound stuff. Once you have everything installed, go into the MIDI Configuration panel, listed under Utilities.
3a: Under the 'Properties' category, you need to select your SB X-Fi Surround 5.1. Click on Speaker Configuration and choose Multichannel, then select 5.1 Surround. Make sure you click apply!
3b: Again under 'Properties' choose the Soundflower (16ch). Click on Speaker configuration and choose Multichannel, then select 5.1 Surround. Make sure you click apply!
4.
This is where things get interesting! Launch AULabs. For Audio Device, choose Soundflower (16ch). You can experiment here, but I found it easier to add filters by manipulating each channel seperatly.
4a: So under Outputs, look for Output Channels and choose 'mono'. Now you'll need to add 6 channels. To prevent crossing signals, you need to make the channels 11-16, instead of 1-6. Now click on Inputs and add channels 1 and 2. Click Okay.
4b: Now, you should have 2 channels under Audio Device and 6 under Master Out. Under Audio Device, look down where Volume is listed. You should see numbers 1-6 listed for each channel. These numbers correspond with the Outputs. For Audio 1 (which is the left channel), you want to choose 1,3,4, and 5. For Audio 2 (which is the right channel), you want to choose 2,3,4, and 6.
4c: Remember, you don't want to close this window, but you can choose File and Save, to save this right now.
5.
Now we're going to configure Soundflower using Soundflowerbed. Under Applications, open the folder for Soundflower and launch Soundflowerbed.
5a: Soundflowerbed is an application that hangs out in the menu bar at the top right. Click on it and look at the Soundflower (16ch) and you want to choose your audio device. for me, I chose SB X-Fi Surround 5.1.
5b: Click on Soundflowerbed again open the drop down menu for the Soundflower (16ch). What we need to do is route sound to the proper places. Under channels 1 and 2, you want to choose 'none'. You might also want to change channels 1-6 to 'none', but that's up to you.
5c: Now you need to route channels 11-16 to the proper places. 11 goes to SB X-Fi Surround 5.1 [1], 12 goes to SB X-Fi Surround 5.1 [2], 13 to 3, etc.
6
Play something! You should have sound going to all 5.1 speakers! Experiment with some filters in AULabs. I'm using the AULowpass filter on channel 4, which is the subwoofer and i've been tinkering with Hipass filtering on the center channel to isolate voices.
Let me know what everyone thinks. There might be a way to use this application to build a true application, but I don't know how. the AULab must be running for these features to work. If you close it, the audio will stop. Enjoy!
