Question about expressions in AE

I don't even know what to look for on google to find the answer. So after an hour poking around inside the AE and the failure in the google search, I come here to ask for help.

I have a (S.redgiant Sound Keys) plugin that gives the values as keyframes for each image. And the values exceed as: 0, 4, 7, 3, 5, 0, 0, 5, 6...

In other words, they oscillate between zero and, say, 10.

I want another layer to obtain this value, but add to himself all the images. I used to do QBasic programs and it's very simple here. Just something like x = x + (value of the key to the plugin)

But I don't know how to do this in AE.

Right now I have this:

x = (thisComp.layer("sound").effect ("sound keys") ("Output 1") * 0.5);

x;

What I really want is:

x = x + (thisComp.layer("sound").effect ("sound keys") ("Output 1") * 0.5);

x;

But it does not work.

Can someone help me please?

AE does not store the persistent temporal variables. You must accumulate the manually and write your own loops.

Expression of speed and frequency

SoundKeys has a built-in accumulate mode, too, so rather than put up with complex expressions, simply use a double instance of the effect and change the values.

  • Small question about expressions 2 Dimensions

    What I do is probably very simple, but I have never tinkered with simple expressions.

    I have a bulge effect and I want the Center to track an object, so I pickwhip the position of the object to the center of curvature, but he needs to go "up" a few hundred pixels. (say 200) How to SIMPLY change the value y of the Ardennes Center?

    I could move the object anchor point and solve the problem, but I'd rather have this knowledge.

    Something like this is probably the most general way to do it:

    target = thisComp.layer ("target");

    fromComp (target.toComp (target.anchorPoint)) - [0,200]

  • Question about video drivers Satellite P100-257

    Hello.
    Question about video driver. Version 14.25... Works (tells... 945 GM chipset); 14.27--works but with ocassional problems (tells... 945GM/GU); version 14,29... (said 945GM/GU) - does not work at all - black screen, but you can hear sounds which tells that XP does all right.

    Why that? And what is GU? Pilot info says it is for 945GM, pilot says he's for 945GM/GU.

    All kinds of three said they are for Mobile Intel 945 GM Express chipset. Who initially my machine have said there. In section "video card" my machine said no Intel - some Calg... - don't remember exactly the name.
    Thank you very much.

    Hello

    As much as I know Satellite P100-257 supports the graphics card Mobile Intel 945GM. The code name of Intel's GM Calistoga
    This is not the same thing as the chipset Intel 945GM/GU. Both are different and so the graphics drivers are not totally compatible!

    The Intel page provides some interesting info on these chipsets:
    Mobile Intel Express Chipset 945GM

    Unfortunately, I have not found anything on the 945GM/GU.

  • Question about the database to use with ESX and Labmanager

    Hello

    Finally my company is buying a permit for Labmanager and ESX server using Labmanager to our tests.

    We had a question about the database that we use for the actual installation.

    Could we use MY - SQL? Or that we have the olbigation to install a SQL or Oracle DB for the whole system to work?

    We prefer to use MY_SQL because it is open-source and will cost less to use for us.

    Thanks in advance for the answer and please excuse my bad English, I'm french spoke first.

    Lab Manager installs SQL Express as part of the installation and use. If you install also Virtual Center as part of your deployment of Lab Manager (do not use an existing VC server), you can use the database SQL Express is included for small installations of ESX, but MY SQL is not an option. You can search the databases supported in the installation guide for what version you deploy.

  • Many questions about the HP 50 g

    I just ordered a HP 50 g graphic calculator! I have a few questions about this so hang on tight! What is the USB connector on the calculator? Mini-USB, micro USB, or is it a connector owner, "custom". Then, it would be possible to connect a keyboard to the HP 50 g by using the USB Port? Is there a program that would make this possible? (I doubt it would work if you plug it..) I have a Mini-USB to female USB 2.0 connector. So I could just plug the keyboard right, provided that the port on the calculator is a Mini-USB Port. If this is not so that I could use my female to female USB adaptor to connect the keyboard.

    (Although these may apply for other similar Satellite/Equium P300.)

    Is the touchpad made by / to use the Alps or Synaptics driver?

    It has the Wireless N network card, is the map made by Intel or Realtec?

    And also, someone has experience with face recognition software to connect?

    If so, does it take a lot of time to initalise?

    Thanks in advance,

    The P300 - 18M belongs to the PSPCCE series.
    It uses the two touchpad drivers. Synaptics & Alps Electric
    There is an Intel 802.11agn minicards WLan installed

    The face recognition is a nice tool but local to be illuminated and you must take your face the right of the post sometimes it of not very easy

  • A few questions about the difference between the Satellite P70, L70, S70

    Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

    (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

    (3) all the three (P70, L70, S70 series) come with the same TFT panels?

    (4) of the above series, which supports mSata?

    (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

    (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

    (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

    Thank you in advance.

    > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

    (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
    As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

    I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

    (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
    See point 1). Different P70, L70, S70 models were equipped with different material parts.

    (> 4) of the series above, which takes in charge mSata?
    As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

    (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
    See point 4) not all models supports the same hardware specifications

    (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
    I don t think that SATA III is supported. I guess it would be SATA II

    (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
    Not easy to answer because there are too many models released in Europea.
    And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.
