Loops in arrange - regionsnot functioning

This issue have been following me since Logic 6 to 7 on my dual G4...and after a big studio-upgrade now also on 8.0.2 and a mac pro.
For some reason In some arangement, not all, (and this can easily be in very light arrangement with not much pressure on anything) If I make a loop in arrange, then certain instruments simply wont play the first notes on the first round. It could e.g be a piano region, which plays the first chord on count 1 smothly. then on count 3 and 4 theres some single notes which wont be played untill half bar later and then like a hikup with both notes at once. Second time the loop runs through it runs smothly....but its very annoying when u want to edit and listen from the start of the bar.
This happens even if I change the instrument. It could be Logic instruments or 3.part. AND ITS driving me nuts for sure. Really hope theres a solution for this..??
Best regards
Bjørn

i have a similar problem right now.
1. on play back, i wont hear the first note.
2. on play back, although i played multiple keys, logic will only play back one of the keys i played.
let me know if you solved this problem

Strange Error Message after Adding Apple Loops to Arrange Page

after dragging some apple loops onto arrange page. i'm getting this error message." audio file "drone Bellos 01 .caf hasn't got sufficient access privilidges so the overview canot be saved. any ideas why this is happening?
thanks

Yes, some of the Apple loops are protected (Jobs knows why). You can change this by searching the file in the finder with spotlight, then hit apple+i->menue opens->click into the lock->set your permissions to "read and write"->done. Unfortunately this procedure has to be performed seperately for each protected loop.

Add loops to Arrange without sync Pitch and Tempo

I recently purchased a package of Audio loops. This package contained audio files in wav and AIFF format. I tried to add the AIFF loops to Loop browser and Logic but it didn't work. The pitch of the loops would change as I dragged them toward the arranment. So I removed them from the loop browser and tried to use the wav files dragging them from the File Folder and when the only to get the same results. It's strange because when I play them on itunes or other programs they're in the right pitch, but as soon as I transfer them to logic the pitch changes.
How can I use these loops in Logic without changing the pitch?

If they are Apple loops...
Use the aiff versions.. and select the region created when you added the loop... Now use transpose in the Region Inspector on the left of the Arrange window.. to set the loop to play at the correct pitch for your piece.
If they are not Apple loops.. use the transpose function as described above and then stretch/flex the region to fit the tempo of your piece.

Multiple Select List looping thru PL/SQL function body returning SQL query

Hi,
I have a Multiple Select List. I want to loop through the values from the Select List and process them in a PL/SQL function body returning a SQL query. Currently, my code only returns the SQL SELECT results of one item in the select list. How do I change my code to make it return the results of all of the items in the select list? (I tested it and it is definitely picking up all the values in the select list).

Thank you,

Laura,
First, I would be careful of introducing SQL Injection possibilities. Any time I see
'Select ... ' || :P123_FOO || ' ... '
I worry about sql injection. In your case you are converting :P50_SELECTED_INSTRUMENTS into selected_items and then selected_items into s. So when I see
'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''' || s ||'%'' '||
I think, "I could use sql Injection and hack this."
So, I would do some validation on :P50_SELECTED_INSTRUMENTS or some other method to avoid this.
I'm not certain I understand your query. Do you really intend to allow the user to select the beginning of a string and then find all rows that start with that string? Or, do you just want to let them find when it matches the string. This is one way if you want to do matching:
DECLARE
selected_items HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
s VARCHAR2(32767);
q varchar2(32767);
BEGIN
-- Change the : separate string to be comma separated with quoted strings
s := '''' || replace(:P50_SELECTED_INSTRUMENTS, ',', ''',''')|| '''' ;
-- htp.p('COUNT: '||selected_items.count);
q:= 'SELECT '||
'SUBSTR(orig_geo_loc_sys,1,INSTR(orig_geo_loc_sys,''-'')-1) AS INSTRUMENT, '||
'SUBSTR(orig_geo_loc_sys,INSTR(orig_geo_loc_sys,''-'')+1, LENGTH'||
' (orig_geo_loc_sys)) AS ORIG_LINENUM, '||
'sum(orig_intrl) orig_intrl, '||
'sum(orig_extrl) orig_extrl, '||
'sum(recv_intrl) recv_intrl, '||
'sum(recv_extrl) recv_extrl '||
'FROM line_usage_sum_view '||
'WHERE TO_CHAR(orig_geo_loc_sys) in (' || s ||' ) '||
--'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''2213003%'' '||
'AND switch_id = ''' || :P1_SWITCH_ID || ''' ' ||
'AND call_start_date > TO_DATE(''30-NOV-1999'') ' ||
'AND call_clear_time > TO_DATE(''30-NOV-1999'') '||
'AND '||
:SORTFIELD||' BETWEEN '||
'TO_DATE(:STARTDATE,''dd-MON-YYYY HH24:MI'') AND '||
'TO_DATE(:STOPDATE, ''dd-MON-YYYY HH24:MI'') '||
'GROUP BY GROUPING SETS (orig_geo_loc_sys)';
-- htp.p('SQL query: '||q);
RETURN q;
END;
If you want to do something more like you originally stated, try this:
DECLARE
selected_items HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
s VARCHAR2(20);
q varchar2(32767);
BEGIN
selected_items := HTMLDB_UTIL.STRING_TO_TABLE(:P50_SELECTED_INSTRUMENTS);

FOR i in 1..selected_items.count LOOP

END LOOP;

LOOP in PL/SQL Function Body Help Needed

I have a PL/SQL function that I'm trying to run and use a LOOP but I'm having some problems. I know the loop works since it output's two commas for me, which is how many records the query used for the LOOP returns, but I can't seem to find the right syntax to reference the column.
DECLARE
str VARCHAR2(2000) := "";
BEGIN
IF :P21_GLOBAL_ID IS NOT NULL THEN
FOR q IN (
SELECT
ID,
DRAW_DATE,
ENTERED_BY
FROM
SAMPLE_T
WHERE
ID = :P21_GLOBAL_ID
ORDER BY
DRAW_DATE
LOOP
str := str || q.ID || ',' ;
END LOOP;
END IF;
RETURN STR
END;

I just sent you the credentials.
Interestingly, I have this same code for the source of a textarea on the page and the source for a report. I then modified the PL/SQL code as follows:
DECLARE
     varSelect VARCHAR2(32767) := ''; --hold query SELECT definition
     varFrom VARCHAR2(32767) := ''; --hold query FROM clause definition
     varWhere VARCHAR2(32767) := ''; --hold query WHERE clause definition
     varOrderBy VARCHAR2(32767) := ''; --hold query ORDER BY clause definition
     varQuery VARCHAR2(32767) := ''; --hold query definition
BEGIN
     IF TRIM(LOWER(TO_NUMBER(:P21_GLOBAL_TEMPLATE_ID))) IS NOT NULL THEN
          varSelect := 'SELECT SUBJECT_ID';
          varSelect := varSelect || ', SUBJECT_ID AS PHI';
          varSelect := varSelect || ', SUBJECT_ID AS ENTER_DATA';
          varSelect := varSelect || ', SUBJECT_ID AS LOGISTICA';
for varTempQuery IN (

ORDER BY
sti.html_Table_row,
sti.html_table_column
LOOP
varSelect := varSelect || ', ' || varTempQuery.field_name;
END LOOP;
          varFrom := 'FROM     RIX.SUBJECTS';
          varWhere := 'WHERE STUDY_ID = ' || TRIM(LOWER(TO_NUMBER(:P21_STUDY_ID )));
          varOrderBy := 'ORDER BY';
          varOrderBy := varOrderBy || ' subject_label ';
varQuery := varSelect || ' ' || varFrom || ' ' || varWhere || ' ' || varOrderBy;
     ELSE
varQuery := 'SELECT SUBJECT_ID FROM SUBJECTS WHERE study_id = :P21_STUDY_ID;';
     END IF;
RETURN varQuery;
END;
When I run the page now, the textarea has the SQL statement generated from the first IF block, but the report using the statement from the ELSE block. I thought it maybe was a timing issue, but both blocks reference other fields on the page, so it doesn't seem to be a timing issue. Shouldn't be a condition issue either with the IF block as the textarea and report use the same source, but are evaluating differently.
Very odd (to me at least).

I am trying to stop my animated gif from looping but the 'once' function won't work

HI,
I have created a small animation for a web banner and I have selected it to only play once, but the export plays continuously. IS there another way of making sure it only plays once? I have got it ticked in the 'Save for Web' dialog box to only play once as well.
Thanks! Jen

I had this same problem. I was exporting around 10 gif banners for a campaign, but the glitch only affected a few.
I wish I had a more airtight solution, but I eventually fixed the problem for each of the effected banners by "jiggling the keys" a bit- that is to say restarting Ps, deleting the animation and starting again, and even deleting the entire PSD and starting from scratch. Was a real nuisance and set me back a good couple hours, but still got those gifs to stop looping.

How to stop while loop when a specified function is terminated?

I want to make a program which has 2 thread, one of which is to control some devices, and the other is to measure outputs of the devices.
To do that, I should make a 2 independent loops, but there comes a problem here.
I want to terminate 2 loops at the same time, but it's difficult for me to do that, because when I try to notify upper sequence's termination to lower loop by some value change, they have some dependency.
That's why I need your help. I want to know how to stop lower loop when the upper sequence's termination keeping their independency.
Please let me know. Thank you.

Is the upper loop commanding the lower loop at all? I would think you would have some type of communication between the loops. Just use that communication to send a stop command. Or the next best way is to just simply use a notifier.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Loop add button not functioning correctly

Hey all,
I have been trying to get a for loop to produce buttons based
on a value.
My current code is:
var xPosition:Number = 50;
var yPosition:Number = 15;
//problem one is that "rows" is a variable from the html page
the swf is
on, I have had it working on other flash programs, but unable
to get it
working on this, but for the purpose of this, I can replace
it with a
numeric value e.g. "3".
//but this causes the main problem, if it is set to 3, the
3rd button
only appears, if set to 2 the 2nd button only appears.
for(i=0;i<rows;i++){
_root.attachMovie("button","btn"+i,_root.getNextHighestDepth());
_root["btn"+i]._x = xPosition;
_root["btn"+i]._y = yPosition;
yPosition = yPosition + 25;
//Does anyone have any idea's for this?
Thanks in advance.
Slpixe

trace(btn0); ect
i was tracing out the btn in the loop. because its only
appearing once
is resulting in only 1 button appearing at a time,
I attempted having the resulting button componnents all
returning
different names, but that resulted in no buttons appearing
(_root.attachMovie("button"+i,"btn"+i,) i tried
OMG WOW
100+i works! all the buttons are appearing now! =D
Will do some testing
Thanks loads guys

Function module PTRA_WEB_EXPENSE_REPORT_GET_2 not working when used in loop

Hi All,
I have used a function module PTRA_WEB_EXPENSE_REPORT_GET_2 in a custom fumction module which i am developing fetch the travel expense data . The function module PTRA_WEB_EXPENSE_REPORT_GET_2 returns the travel expense data based on the employee and the trip number. I want to fetch the travel expense data for a given set of employees and trip number and hence i have used this function module inside a loop statement.
The function module returns the travel expense data for the employee and trip in the first loop pass. From the second loop passs it doesn't return the value. I have also checked this in se37 and the same thing happens. Value is returned for the fist employee but for the next employee we have to go to initial screen of se37 and execute the Func. module again.
I debugged this function module and found that the value of the employee and the trip number is stored in the global variable. The value passed for the employee and trip is compared with the correspomding value in the global variable and if they are not same an error message is returned. Since we are using in a loop , each time a different value is passed for the employee and trip and the check fails .
Is there any way to clear the value in the global parameters or is there any other function module which can be used to clear the values of the global variables?
Thanks!
Regards
Manipal Parkala

Hello Archana,
May be we can try several ways...
1) can you try calling function module BUFFER_REFRESH_ALL ??
after each call...
2) May be u can call Function module "PTRA_WEB_EXPENSE_REPORT_GET_2 " in background task or seperate task , it will load the function group everytime when u call it in loop.
***DO let us know if it does not work.
thanks

Javascript For loop not working within a function

Hi all,
I'm a beginner to LiveCycle and I cant seem to get a loop working within a function. The function is being called successfully because when I manually create the code it works but I am trying to clean things up.
So here is my working example:
function hideContent() {
        MainFlowedSub.LevelsSub.Table1.presence = "hidden";
        MainFlowedSub.LevelsSub.Table2.presence = "hidden";
       ... and so on....
         MainFlowedSub.LevelsSub.Table8.Row1.presence = "hidden";
        MainFlowedSub.LevelsSub.Table8.Row2.presence = "hidden";
       ... and so on....
However when I try and creat a loop instead of listing every sing table/row nothing happens. this is important to my project as there will be alot of different rows depending on radio button selections earlier in the form. Below is the current state of my code:
function hideContent() {
    var i=0;
     for (i=1;i<=5;i++)
         MainFlowedSub.LevelsSub.Table[i].presence = "hidden";
    var j=0;
     for (j=1;j<=23;j++)
         MainFlowedSub.LevelsSub.Table8.Row[j].presence = "hidden";
    var k=0;
     for (k=24;k<=88;k++)
         MainFlowedSub.LevelsSub.Table8.Row[k].presence = "hidden";
this will then continue as there will be hundreds of rows.
Any help will be greatly appreciated and I am sure I am making a basic error so thanks in advance.
j

thanks for your help paul. Again, really appreciated as I know very little about all this.
Unfortunately its still not working... One thing I am sure of is that I am doing something very basic wrong. So here is my code, I have applied your suggestion above which will cover all my data:
To give an understanding, I have 5 tables of content, each has i amount of rows. and I am running this script to clear/remove all items being displayed.
function hideContent() {
    for (var i=1;i<=5;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table[" + i + "]").presence = "hidden";
    for (var i=1;i<=71;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table8.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=93;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table9.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=99;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table10.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=101;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table11.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=87;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table12.Row[" + i + "]").presence = "hidden";
It has to be something to do with my For loops because if I manually insert each line it works perfectly.
Thanks again,
johnny

CVI XML Functions Execution Times Increase When Looped

I have written multiple functions using CVI that read XML files. I have confirmed in the Resource Tracking utility that i have cleaned up all of my lists, elements, documents, etc. I have found that when I loop any of the functions I have created, the execution times increase. The increase is small but it is noticable and does effect my execution.
Are there any other sources of memory that I need to deallocate? It seems that there is a memory leak somewhere but I am unable to see where this increase is located.
I am currently running LabWIndows/CVI 2009 on Windows 2008 Server. I have looped my functions using TestStand 4.2.1. Any help would be appreciated!
Thanks in advance,
Kyle
Solved!
Go to Solution.

HI Daniel,
Thanks for the quick response.
It is indeed slow down in execution speed when we loop. When looped, the XML reader is overwriting variables, not adding to an array. Our application is structured differently than my test case. We run a CVI function from TestStand that contains a series of commands, which contains the XML reading. The XML looping is really done in CVI. I used TestStand in my test case just to get execution times. Our psuedocode for the CVI function is as followed:
For loop (looping over values, like amplitude or frequency)
Reading the XML
Applying the data from the XML to set up some instrument(s)
Do something...
End loop
I can confirm that the instrument set up is not the cause of the slow down. We have written the same XML reading in C# and applied the values to the instrument setup and do not experience the slow down.
I tested with On-The-Fly Reporting enabled and the execution time continued to slow down.
I hope that answers all of your questions!
Thanks,
Kyle

Loop I created: how to remove?

Hi,
I've been 'hitting' the 'delete' button to no avail to remove a loop I created. Anybody knows how to remove a loop I created accidentally? I don't want to know how to remove loops provided with the software. I only want to remove my own loop. Thanks.
Using Logic Pro X V10.0.4 with Macbook air 2013.

Try this: 1st go to your project settings>assets and make sure that the first box (copy audio files into project) is not checked. Then drag your loop into the project. If it is a MIDI loop you will need to drag it to an audio track, if it is an audio loop then drag it to a blank area of the arrange and a track will be created. Need I say you should do this on a fresh project in case there already is a copy in the project folder? Now select the region and go to (local arrange menu) functions>show audio file in finder (the key command on my system is shift+command+R). That is where the loop is.

Loops "missing" but still in library

Upon update, many loops went 'Missing" although they are in the loop library still.
Have tried several attempts to re-index loops to no avail.
For instance, "Live Edgy Drums 07" remains, but "Live Edgy Drums 29.2" does not and has no sound.
in sound effects, "Airplane Takeoff" is in the loop library and is functioning, but "is not found" in my composition.

how do i get them back into my playlist?
On the left side ofTunes, drag from Library -> Music to the playlist you want it in.
why does it keep doing this?
Are you deleting the playlists the song(s) are in?

Difference between abap object and function

hi all,
i read the book on abap object of the difference between abap object and classical abap.
i know that there is only 1 instance of a specific function group but somehow i still not so clear why subsequent vehicle cannot use the same function. i also can use the do and loop to call the function? if cannot then why?
hope can get the advice.
thanks

Try to repeat this using a function group and I think you'll undestand because it'll be very hard to do it.
By only one function group how can u read the data of a certain vehicle?
Yes you can create in the function group an internal table where u store the data of every car: in this way u use the internal table like it was an instance, but you should consider here the example is very simple. Here we have only the speed as characteristic, but really we can have many complex characteristics.
