Keys playing two different sounds at the same time

I keep getting one of the synths whenever I'm playing the Pop Kit, or any drumkit, with my MIDI. Basically when I hit a key, two sounds come out of it when it's only supposed to be one. I've rebooted GB and the MIDI with no success. How can I fix it?

That's weird - never heard of that phenomenon. Could it be that the second sound is coming out of your keaboard? What's your setup?

Play two video files at the same time.

I am trying to play two video files at the same time. I create two threads, each of which has its own frame, playing button, and builds its own graph to play the file. Now everything seems works except that when the first file is being played and I hit PLAY
to play the second file, the program plays the second file but the first one is paused; furthermore the control button has no response for the first one. Did I miss anything? Can anyone help me figure out the problem?
Best,
Fayin

You don't need separate threads for 2+ playback pipelines because the filters create worker threads internally and don't block execution on calling thread.
If you decide to keep separate threads, you will have to follow Michel's advice and have message pumps on those threads.
You can also have both files in the same graph, in which case you have perfect sync between them (both start playing together in sync), however you cannot pause/stop/run files separately.
The problem you described is most likely not a DirectShow problem and is rather about generic threading, COM or window messaging.

Control two different parameters at the same time

Two motors were connected each other rigidly. One motor controlled torque and the other motor controlled speed. I generated some torque and speed data which represented one cycle of motion from a motor simulation. I like to send these two different data sets (torque and speed) to two different motors at the same time. Torque data sends to one motor and speed data sends to the other motor to see the response of the load profile. In order to do this, I thought about using multithread, but I am not sure it will work for this application. Usually multithreading delay the CPU time so the overall control process might be delayed, right? If you have better idea, please let me know.

If you are using one motion controller to control both motors, you will probably run into problems if you try to use multithreading on the PC. However, you can execute up to 10 programs (threads) at a time, in addition to host communication, using on-board programming. For more information on on-board programming please refer to the following tutorial: Developer Zone Tutorial: On-board Programming in FlexMotion

Collecting data from advantech-usb4704 with two different apps at the same time

I wonder if I can access to Advantech-4704 with two different applications at the same time?
I use this block in my vis.
I have enough ports, but inputs are needed in completely different applications. Do I have to close one of them or can they run simultaneously?
Thankyou!

Dear gtu,
as nathand said, usually it is not supported to access the same physical resource simultaneously from multiple programs. In case of DAQmx for instance, you will get an error message which says that the resource is already reserved. I suppose the same would happen with your driver, however it might be worth a try.
One workaround could be however if you revise your applications and merge the codes if it is possible so that no concurent resource allocation takes place.

How can I log into two differant accounts at the same time in two windows without the second window affecting the first.

I'm trying to log into two facebook accounts at the same time in differant windows. When ever I log into the second account in the second window it changes the login in the first window. When I hit home or any other link the first window account has been logged out and logged into the second window account. I tried installing a second copy of firefox in a differant folder that the first but it seems to use all the files of the first installation. If I can get 2 toatally seperated instalations that don't rely on the same history, cookies, cache, etc I belive that will solve my problem. Please help.

Nah, that won't work. Facebook has a feature that gets your IP Address, so as soon as you sign into one on the same computer, it changes the other login for safety purposes (say, someone was on a public library PC. They forgot to log out. Someone else logs in, and it automatically logs them out). You'll need 2 computers to do that.

Is it possible to realize two different processes in the same time with TDMS?

Hello all,
we have one TDMS but a lot of workstreams. Is it possible that 2 different workstreams in the same time realize anonymization in TDMS?
Thanks in advance!!!
Ilkin Mammadov

Hello Anita,
I am sorry.I mean we have a lot of projects (for example Procurement, Finance, Logistics, etc) and each of them wants to anonymize. But it is existing just one TDMS. Can these projects start with anonymization in the same time or they have to wait till one of projects finished anonymization?
Thanks in advance!
Best regards,
Ilkin

HT2688 How to play same song of two different computers at the same time

Hi I have turned on Home Sharing. So one computer can play music on another. Is there any way to have one computer play what the other computer is playing at the same time. Other than just starting the same song as close in time as possible on each computer.

create an album of all of the photos you want to order, open the album, select all and order - be sure teh photos are cropped to the print size so unexpected cropping does not occur during the printing process

Possibility of Apple TV playing one Itunes Library while the computer plays a different library at the same time (Mac)

The Apple TV is for my son's room to watch his videos, listen to music, etc. off his iTunes library I made for him on my Mac. I want to be able to listen to my own library at the same time he has his. Apple TV only recognizes the current library open; unless I'm doing something wrong or the stars haven't aligned for me yet, is there a way to do this? I can't run two iTunes at the same time (wish I could).
*Note- to teach my son about computers, I bought an old green iMac which will be for his learning venture. The iMac however does not have wifi (at least not yet). Perhaps something for you Mac professionals can use to help me whip up a good setup, unfortunately the iMac is slow, not enough HD space, so I don't have the funds right now to open it up and do what can be done. (If this helps)

Hi All,
Same issue here. Just upgraded (?) from the previous version of Apple TV, to the new Apple TV2. Like others here, my main problems seem to be with unreliable streaming from iTunes 10 on my PowerMac (Quad G5, Leopard OSX).
My original AppleTV had no issues w/the wireless network, or synching w/my PowerMac.
The network connection from the ATV2 are fine, and have no issues accessing the Apple Store (for movies, TV shows), or accessing Netflix. The access to the internet from my ATV2 is quite robust.
My problems are with keeping a constant, reliable wireless connection to my PowerMac, via an Airport Extreme wireless router.
I have tried multiple restarts, reboots, reset ATV2 to original settings, tried different wireless channels on the Airport Extreme, verified I have Home Sharing properly enabled in iTunes,etc, but no luck so far.
What I'm seeing is when I access my iTunes on my computer, I can see my library, and then if I start to "shuffle songs" I may get 1 to 3 songs to play fine, but then the music stops, and I can no longer access the music/movies/etc in iTunes any longer. When I then go to my PowerMac, it has lost most bars of signal strength on the wireless network (although all other devices show strong signal strength), and I have to Turn AirPort Off, then Turn AirPort On and I then am reconnected to the wireless network with good signal.
I then go back to the ATV2, connect to my iTunes, start my music, and then 1-2 songs later it again stops playing, and I go through this all over again.
It seems as though there is something on the wireless network between the ATV2 and my PowerMac that causes it to lose connection, and I have to manually start again. The problem is that the connection is not robust, and only lasts a few minutes.
Hope this gets solved soon.
Regards
Tom

Is there a way to see or play two video tracks at the same time?

I have video shot using two cameras at the same event. If I take the video and put it in a sequence, say video1 and video2, how can I watch both tracks at the same time so I can edit them? I tried using multi-camera monitor and have that show video1, while watching video2 in the right hand panel, but it doesn't work very well. By that, I mean the multi-camera monitor does not play at the same time. Instead, it stops, then when I play the other monitor it is still until I stop the other one. Then, it "catches up". If I play the multi-monitor, the other one is still until I stop the multi-cam monitor. So, anybody have a better solution that I can use where they both play at the same time?
BTW, my hardware is brand new and I have a 6-core i7-3930K processor with 16 GB of memory, so I don't believe the problem is with my hardware not being enough to run PPro 5.0 correctly.

Macbook Pro: Play and record sound at the same time

Greetings everyone,
My brother and I have are going to switch go a mac, preferebly to a macbook pro. we used windows so far, but the frustration has grown extremely huge, so it's time to throw off this junk.
We've been working with sound a lot and many times we recorded any sound which played through the computer: that means sound and music from dvds and games or other sources, we couldn't get anywhere else. What we did is simply letting the game or dvd play and record the audio at the same time.
I've testet this functionality in windows via bootcamp on a macbook of friend of mine, but NOT the macbook pro version. It's wasn't really that good as I thought. Sound quality was below what I'd expect.
So here are my questions:
- Does the macbook pro have a better sound card, which enables simultaneos play + record?
- Is good record quality bound to a software I need to use?
Thanks for your replies.

Apple don't have separate "sound cards" like PC's , Martin. The necessary hardware is proprietary , and built into the logic boards.
Both of them have high quality combined optical digital input and audio line in, and combined optical digital output and audio line out. You can also attach various USB or firewire audio input and output devices if you wish. So as far as 'quality" goes, it depends what you are playing them through more than anything else. The inherent audio abilities of both are pretty danged good when using Mac specific software. That is why the music industry love 'em!
Or are you just talking about sound quality through the built in speakers, which are, of course severely limited by the amount of space available, though I've heard far worse from many PC notebooks!?
Cheers

How to compare two different characteristics at the same time in polestar

Hi Gurus,
I would like to analyse the e fashion universe in polestar with comparison of previous year product line with current year product line at the same time.
is there any way to do that we can compare two years of the product line sales revenue at the same time with comparison chart like 2003 T shirts vs 2002 T shirts
in polestar we can compare the two measures at the same time but i want to compare the sales revenue of product lines of two years in a comparison chart at the same time.
Regards and thanks
Abid Paul

Hi Stratos,
I am actually able to compare the Measures but i want the comparison between the two different characteristics like this year productline vs last year productline at the same time with say one measure like sales revenue or any other.
Is it possible to compare the both and it should represent in the chart as well at the same time.
In the polestar i can compare three measures at the same time but i want to compare characteristics like year 2009 productline VS 2008 productline with one measure say sales revenue.
I would really appreciate if you could help me out.
Regards and thanks
Abid

Playing two FLV's at the same time

Hello,
OK, this seems like it would be simple, but I cannot get it
to work. I have 2 flv's that have to play at the same time - one is
a prof. in front of a electronic microscope and the other is the
actual feed from the microscope - so I need them to be able to be
controlled by one set of components. So, I have tried everything in
my ability. Currently, the setup is as follows:
I have 4 layers
Actions - where this script resides
myVideo.playPauseButton=myPlayButton;
myVideo.seekBar=mySeekBar;
myVideo.volumeBar=myVolumeBar;
Player - play/pause, seek, and volume bar reside
Scope - FLV of microscope
TH - FLV of talking head
Both my Flv's have an instance name of "myVideo" and when I
test the swf, only the last layer plays and is controlled (if the
Talking Head is in the last layer that will play and vice versa).
I cannot figure out, nor find anything, anywhere on how to
control both these FLVs with only one comonent.
Any help would be appreciated.
Thanks much
Jason

Playing more than one FLV will result in more than one
NetStream object. Each NetStream object plays independently. Add to
that each progressively downloads separately so one may begin
playing before the other. Attempts to seek a point in the videos
will also be unpredictable unless cue points where added during
encoding. But then playing from the cue point is unpredictable.
The best plan for video like this might be shorter lengths or
combining into one.
You can combine the raw video files in Premier or Windows
MovieMaker and then publish and then encode one FLV.

Is it possible to order two different cards at the same time? I do not want to pay shipping costs twice.

Hi, here's my problem. I made two different Christmas cards that I want to hand over in person. When I order one however, I can not select the other one, despite the fact that I want them both delivered to the same adress. Is there a way to order both as a bundle?
Thanks a lot
Best, Stefan

Afraid not.
