Changing guitar sounds while looping?

Hello guys!
I am new to mainstage, i am trying to create a concert for live looping!
I want to be able to loop guitars and soft sinths/drums but i am failing to see how can i change the guitar and synth sounds within the same "song" so that i can keep the loopers running...
Any help?
Thanks

Hi
Create the LoopBack channels at Set level. Create the individual sounds and Patches you want inside that set.

In our program, we are concerned about reducing CPU work; how to wait until a boolean condition changes in a "while loop"?

Is there a way to wait until a boolean condition changes (instruction is sent) in a "while loop" (because I want the program run until I press exit button)? Now it is consuming a lot of CPU because it is running the loop very fast waiting for instructions unless I stop the program.
Thank you.

Use /functions/time and dialog/wait until next millisecond multiple in the
loop. Input 100ms.

Plot XY graph from while loop

I am trying to make a curve tracer with a DC power supply, DAQ, and Labview 7.1. Everything is ok, until I want to plot an x-y plot from a while loop. I can do this function fine using a for loop and cluster cells, but I need the while loop for the interruption function. When I change to the while loop, it had data formating issues, but I believe I have it to something that should work. It seems like my xy plots want to graph (the auto scale moves the axis respectively) but I do not get a line. I'm not sure if Labview is seing this as just one point and not an array, or if there is a labview bug. Attached is my code with a few different trials to make an xy plot. If anyone can be of help I would be very thankful.

If it works in a FOR loop, but nor in a while loop, most likely your output tunnels are not autoindexing (FOR: on by default, WHILE: off by default). Right-click on the output tunnels and select "enable indexing".
If you want to watch your graph update during the while loop, you could accumulate your x and y data in a shift register and graph it. (See attached modification).

While loop hangs in my script

Hi guys,
I want to check if SCCM (install windows image) is ready.
If it's not, than it has to sleep. I want this in a while loop because when it takes longer, it must loop another
5 minutes.
When the image is ready it must go back to the rest of this script.
My loop hangs and the script never finishes. What am i doing wrong?
Kind regards,
André
$compObject = get-wmiobject -query "select * from SMS_R_SYSTEM WHERE Name='$hostName'" -computername "dhgms401" -namespace "ROOT\SMS\site_S01"
$compObjectstatus = $compObject.client
do {
Start-Sleep -Seconds 300
while ($compObjectstatus -eq 0)
write "Sccm is klaar "
Write "$hostName has been started"
$newHostName = Get-ADComputer -filter {(name -eq $hostName)}

Not 100% sure but, I believe the issue is with your conditional statement for your while loop
while ($compObjectstatus -eq 0)
$compObjectStatus will never change so your while loop will never equal 0 unless it did from the begining. You will have to requery each time to get an update on the status, so possibly create a function on the query end of things, and just run the function
Function GetStatus
$compObject = get-wmiobject -query "select * from SMS_R_SYSTEM WHERE Name='$hostName'" -computername "dhgms401" -namespace "ROOT\SMS\site_S01"
$compObjectstatus = $compObject.client return $compObjectstatus
do {
Start-Sleep -Seconds 300
while (GetStatus -eq 0)
write "Sccm is klaar "
Write "$hostName has been started"
$newHostName = Get-ADComputer -filter {(name -eq $hostName)}
I cannot test so I do not know if it works as expected

Can't write to instrument in while loop.

in my case, I use 2 while loop for the progarm. one is to write the data to the instrument, another one is use local variable to change the data depend on time. the problem is the data which need write to the instrument does change. but another while loop doesn't write it to the instrument unless I push highlight excution in the diagram or choose save as in the file. could anybody help me to find the problem?

Hi Akuma,
the fact that it works when you highlight execution implies (perhaps) a race condition. The lightbulb serializes the execution of your VI, so that functions execute in succession although they don't depend on each other. When you then run the VI in realtime, some functions are executed at the same time, e.g. "VISA flush buffer" and "VISA write". It is important to define the order the VIs execute on your VISA interface for instance by wiring the error-cluster.
If this doesn't help, then post your VI (or a simplified version) or a screenshot of the diagram.

Cursors vs while loop

Hi,
We know cursors are evil, use lot of memory, adds up tempdb activity, not scalable, hinders concurrency etc...Say if I replace 10 heavily used cursors in OLTP system with while loops how much do I gain if any and
how can I measure that. How can I convince my code review DBA to make this change? Does this change help the server?

The big gains (orders of magnitude) will come by changing cursors to set-based statements as you've done. If you can avoid row-by-row looping (through cursors or otherwise), then you should see some good gains there as well. In SQL Server 2005's CTEs and MARS we've removed some of the remaining need to use cursors and loops. But there are some situations where row-by-row processing still seems to be needed, and performing some non-set-based statement for a set of rows is the primary example .. executing a DBCC command for each database, for example.
If you find you are calling a stored proc for each row, perhaps you can pass a table containing the rows into the stored proc (perhaps by using a temp table) and then use set-base operations inside the stored proc, but there are times when you just need to call the sp row by row. If, after investigating all the set-based alternatives, you find you really do have to process rows one by one, then cursors are one way of iterating through a set of rows, and they do provide some good functionality with a well-defined behavior and you'll probably use your cursor together with a WHILE loop.
If you don't use a cursor to hold the rows to process, you'll have to retrieve a single row yourself each time through the loop; that'll probably be more coding for you, increase the potential for more bugs in your code, perhaps be more costly during execution, etc. So the trade-off becomes one of using cursors with a known downside, versus custom code with other potential drawbacks.
I'd say the "change cursors to while loops" statement oversimplifies the situation and falls way below the "change cursors to set-based operations where possible" primary guideline .. and it's unfortunate that it's at the top of the list in the article you mention.

I want to pass along a couple of tips that will get you more and better response on this list.
1) There is an un-written rule that says more "stars" is better than just one star. Giving a one star rating will probably eliminate that responder from individuals that are willing to anser your question.
2) If someone gives you an answer that meets your needs, reply to that answer and say that it worked.
3) If someone suggests that you look at an example, DO IT! LV comes with a wonderful set of examples that demonstate almost all of the core functionality of LV. Familiarity with all of the LV examples will get you through about 80% of the Certified LabVIEW Developer exam.
4) If you have a question first search the examples for something tha
t may help you. If you can not find an example that is exactly what you want, find one that is close and post a question along the lines of "I want to do something similar to example X, how can I modify it to do Y".
5) Some of the greatest LabVIEW minds offer there services and advice for free on this exchange. If you treat them good, they can get you through almost every challenge that can be encountered in LV.
6) If English is not your native language, post your question in the language you favor. There is probably someone around that can help. "We're big, we're bad, we're international!"

I'm new using Logic, i've been using garageband for quite awhile now though but my question is just basic. When i want to record electric guitar while clicking the software option it brings me to alot of guitar sounds that i want to chose. I chose the twangy electric or the distorted strat but i only hear clean sounds. No matter what kind of guitar sound i chose in the library it only produces clean guitar. How can i make it sound like it supposed to? Did i miss something i should do?

This definitely has me stumped as I'm unsure as to why your guitar can be heard, but with none of the channel strips plugins applied to the sound.
On the record enabled channel strip that contains your guitar input, is the "I" button located near the "R" active? Also, if you record your guitar, can you hear the FX applied to it when you play back the recorded track?

While Loop to Monitor a 1D 8Bit boolean Array for changes

Hi;
I need help in monitoring a 1D 8-bit boolean array for a value change. I think I need to use a while loop with shift registers???
Any suggestions?
Thank you,
4BoysDaD

Where are you going to put it in your code. It will depend on what you are already doing. Here is an example to show you how to do it with out shift registers.

Problem with while loop in thread: starting an audiostream

Hello guys,
I'm doing this project for school and I'm trying to make a simple app that plays a number of samples and forms a beat, baed on which buttons on the screen are pressed, think like fruity loops. But perhaps a screenshot of my unfnished GUI makes things a bit more clear:
[http://www.speedyshare.com/794260193.html]
Anyway, on pressing the play button, I start building an arraylist with all the selected samples and start playing them. Once the end of the "screen" is reached it should start playing again, this is the while loop:
public void run(){
        //System.out.println("Wavfiles.size =" + getWavfiles().size());
        System.out.println(repeatperiod);
        if (getWavfiles() == null) {
            System.out.println("Error: list of Wavfiles is empty, cannot start playing.");
        else{
            if(!active) return;
            while(active){
                System.out.println("Wavfiles.size =" + getWavfiles().size());
                for (int i=0; i<getWavfiles().size(); i++){
                    Wavplayer filePlayer = new Wavplayer(getWavfiles().get(i).getStream());
                    Timer timer = new Timer();
                    //timer.scheduleAtFixedRate(filePlayer, getWavfiles().get(i).getStartTime(),repeatperiod);
                    timer.schedule(filePlayer, getWavfiles().get(i).getStartTime());
                try {
                    Thread.sleep(repeatperiod);
                } catch (InterruptedException ex) {
                    Logger.getLogger(LineBuilder.class.getName()).log(Level.SEVERE, null, ex);
    }But once the second iteration should begin, I'm getting nullpointerexceptions. These nullpointerexceptions come exactly when the second period starts so I suppose the sleep works :-) The nullpointerexception comes from the wavfile I try to play. Wavfile class:

     public Wavplayer(ByteArrayInputStream wavstream) {
          try {
               audioInputStream = AudioSystem.getAudioInputStream(wavstream);
          } catch (UnsupportedAudioFileException e1) {
               e1.printStackTrace();
               return;
          } catch (IOException e1) {
               e1.printStackTrace();
               return;
                AudioFormat format = audioInputStream.getFormat();
          DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
                try {
               auline = (SourceDataLine) AudioSystem.getLine(info);
               auline.open(format);
          } catch (LineUnavailableException e) {
               e.printStackTrace();
               return;
          } catch (Exception e) {

               return;
    @Override
     public void run() {
                System.out.println(auline);
          auline.start();
          int nBytesRead = 0;
          byte[] abData = new byte[EXTERNAL_BUFFER_SIZE];
          try {
               while (nBytesRead != -1) {
                    nBytesRead = audioInputStream.read(abData, 0, abData.length);
                    if (nBytesRead >= 0)
                         auline.write(abData, 0, nBytesRead);
          } catch (IOException e) {
               e.printStackTrace();
               return;
          } finally {
               auline.drain();
               auline.close();
}auline is null on second iteration, in fact, getAudioInputStream doesn't really work anymore, and I don't know why because I don't change anything about my list of wavfiles as far as I know... Any thoughts or extra info needed?

Is my question not clear enough? Do you need more info? Or is nobody here familiar with javax.sound.sampled?

Track Enabled To Record Distorts my Guitars Sound

When I enable a track to record it alters the sound of my guitar. It almost sounds like the distortion effect is being applied twice which makes it the sound full of static and just crappy.
If I disable the record button the guitar sound goes back to normal.
Any ideas??? I'm totally stumped.
other info:
The GNX4 is connected via USB to the laptop and LE8
The laptop is configured to use the USB interface as the input and output for audio

The LE8 track is a simple audio track with no plugins applied. I'm not using any of the features in LE8 to alter the sound of the guitar.
My GNX4 1/4 outputs are connected to a simple mixer (with no effects enabled or anything else to alter the guitars sound) and my speakers are plugged into the output of the mixer.
When I disable the LE8 track for recording my guitar sound is perfect. I hit the record button and it changes the sound. I don't know what other information I can give????
Its almost like hitting record causes some kind of signal loop that is applying the GNX4 effects twice before LE8 records it. I can't explain how that might be happening but that is what sounds like is happening.

How to use one single boolean button to control a multiple while loops?

I've posted the attached file and you will see that it doesn't let me use local variable for stop button, but I need to stop all the action whenever I want but more than one single button on the front panel would look ugly... The file represents the Numeric Mode of

In order to use a local variable, you can change the mechanical action of stop button (Switch When Pressed will work), or create a property node for it and select values. You'll also have to do a lot of work changing those for loops into while loops so that you can abort them.

While loop doing AO/AI ... Performance?

Hi!
I have been trying to get a VI to do concurrent Analog
data in and out and both the input and output rates and
waveforms can change while the VI is running. My problem
is this:
(a) If I try putting the read and write operations in
separate while loops, one or the other loop will
die in a buffer over/underrun.
(b) If I put both into the same loop, then this works
but I am limited in the choice of data-rate parameters
because eventually one or the other DAQ VI will take
too long.
At this point I have only one loop and the buffers are big
enough to hold 10 iteration. Every time one of the loops
dies I reset it. Still this seems awkward. Is there a
way of improving on the loop overhead and putting t
he
input and output in separate loops? Or any other way to
improve performance?
Rudolf

Ok, I knew that ocurences did something useful but I am
still a bit confused:
* Can you set an occurrence for an output event. None
of the examples I've seen say so but it looks like
it should work
* How do occurrences actually help with the "hanging"
problem. Does the compiler see the occurrence in
a loop and change the wait parameters?
I looked at devzone but most of the stuff I found there,
even the promising looking stuff was all about
synchronizing and triggering, not about occurrences.

Can not pass data after while loop

Hello.
I have created a VI for my experiment and am having problem passing data outside a while loop to save on an excel file. The VI needs to first move a probe radially, take data at 1mm increment, then move axially, take data radially at 1mm increment, then move to the next axial position and repeat. It would then export these data to an excel file. The VI is a little complicated but it's the only way I know how to make it for our experiment. I have tested it and all the motion works correctly, however I can not get it to pass the data after the last while loop on the far right of the VI where I have put the arrows (Please see the attached VI ). Is it because I'm using too many sequence, case, and while loops? If so, what other ways can I use to make it export data to the excel file?
Any help would be appreciated.
Thank you,
Max

Ummmm .... gee, I'm not even sure where to begin with this one. Your VI is well .... ummmm... You have straight wires! That's always nice to see. As for everything else. Well... Your fundamental problem is lack of understanding of dataflow programming. What you've created is a text program. It would look fantastic in C. In LabVIEW it makes my heart break. For a direct answer to your question: Data will not show up outside a while loop until the while loop has completed. This means your most likely problem is that the conditions to stop that specific loop are not being met. As for what the problem is, I don't even want to start debugging this code. Of course, one way to pass data outside of loops is with local variables, and hey, you seem to be having so much fun with those, what's one more?
This may sound harsh, and perhaps be somewhat insulting, but the brutal truth is that what I would personally do is to throw it out and to start using a good architecture like a state machine. This kind of framework is easy to code, easy to modify, and easy to debug. All qualities that your code seems to lack.
