G5 compared to a iBook using Logic

Hello
I did a quick comparative test between my girlfriend's iBook and my G5, i thought i may share it here.
G5 is a brand new dual 2 ghz with 2,5 go ram, 2 hard drives of 160 gb each, Tiger 10.4.2
iBook is a brand new 12" G4 1.33 ghz with 512 mb ram, 1 hard disk of 40 go (4200rpm), Tiger 10.4.2
both running Logic Express 7.1, using internal audio soundcard with the same default buffer settings.
The aim was to open as much stereo Guitar Amps as possible, using stereo tracks. On these tracks i imported an audio .wav file of 2 mins long, 16bits 44 khz
you can only open 5 plugins per track in LE 7.1 , don't know on Pro.
results :
iBook 1,33ghz : 13 guitar amps opened on 3 different tracks
G5 2X2 Ghz : 48 guitar amps opened on 10 different tracks
with one more guitar amp opened i would get a "CPU overload" message on each machine.
this would mean a dual 2 ghz G5 is 3.69 times more powerful than a 1.33 ghz iBook.
this is not the most revelant test you'd find but it gives you a rough idea ...

That's only an indicator as to how many Guitar Amp plug-ins it can hold (and you are also talking Logic Express, so it may differ with Guitar Amp Pro). The numbers will most likely differ with delays, reverbs, compressors, limiters and other stuff that we're bound to use in our productions.

  • How to use logical operator

    Hi ,
    I hava a problem while using logical operators.
    I wrote a procedure to compare two strings.please check the following.
    CREATE OR REPLACE PROCEDURE comp_str(sour_str IN varchar2,targ_str IN varchar2) AS
    leng_sour_str number:=NVL(length(sour_str),0);
    leng_targ_str number:=NVL(length(targ_str),0);
    leng_str number:=NULL;
    BEGIN
    IF sour_str IS NULL THEN
    dbms_output.put_line(leng_targ_str);
    elsif targ_str IS NULL THEN
         dbms_output.put_line(leng_sour_str);
    ELSE
         select utl_match.edit_distance(leng_sour_str,leng_targ_str) into leng_str from dual;
    END IF;
    dbms_output.put_line(leng_str);
    IF (leng_str > 0) OR (leng_sour_str > 0) OR (leng_targ_str > 0) THEN
    dbms_output.put_line('Strings are not same');
    ELSE
    dbms_output.put_line('Strings are same');
    END IF;     
    END comp_str;
    IF (leng_str > 0) OR (leng_sour_str > 0) OR (leng_targ_str > 0) statement is not verifying the conditions properly.
    Please suggest me that how to write multiple conditions with OR Operator or any alternative.
    thanks in advance.

    They are working exactly as you expect it. The problem in your code is probably the "utl_match.edit_distance"-procedure. Do you know the outcome of this procedure?
    Why don't you try something like
    declare
      l_string1   varchar2(255) := 'String1';
      l_string2   varchar2(255) := 'String 2';
    begin
      if length(l_string1) > length(l_string2) then
        dbms_output.put_line('String 1 is longer than String 2');
      else
        dbms_output.put_line('String 1 is shorter than String 2');
      end if;
    end;This way, you can change one string or the other and see, how it works. With utl_match.edit_distance you need to know what exactly they are computing to see what the logical comparison is doing.

  • How to pass parameter in "Filter By Using " Logical SQL

    Hi
    Newbie in BI Publisher and OBIEE.
    I have the following requirement;
    Generated the Logical SQL and added as New Dataset to BI Publisher Data Model.
    The Logical SQL has statement as;
    SELECT
    0 s_0,
    AGGREGATE(FILTER("BISubjectArea"."Comparative"."ME % - Account" USING ("BISubjectArea"."Common"."RPT_Date" = date '2011-10-31')) BY "BISubjectArea"."Classifications"."Country") s_1,
    I want to parameterize the query by providing Data Model Parameters to the Filter By Statement. Example of what I want.
    SELECT
    0 s_0,
    AGGREGATE(FILTER("BISubjectArea"."Comparative"."ME % - Account" USING ("BISubjectArea"."Common"."RPT_Date" =:Prior_date)) BY "BISubjectArea"."Classifications"."Country") s_1,
    By providing this; it doesn't give any syntax error and accepts it. But when trying to run the Generate XML option, it gives out XML Tag error.
    Please help to resolve this and thanks in advance
    I am using OBIEE 11.1.1.5 version ...
    Edited by: 908476 on Jan 17, 2012 1:12 AM

    I have not worked with 11g version but I believe that if you use Answers as a datasource then you can not have parameters on the BI publisher side. Not sure if that has changed. Please let me know if this is incorrect.
    I guess you would have to use dashboard prompts and presentation variables and note that the Presentation variable MUST BE same as the parameters defined in the BI Publisher. Take a look at the following link for an example.

  • How to use Logical database in function module?

    I will create a function module in HR.
    but how to use Logical database  in function module ?  Logical database PNP always show screen.in function (RFC) code , it is a matter.

    You cannot attach the LDB to the main program of the function group.
    - So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
    - Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table

    i am trying to use logic pro 9 on my lion system and it continues to say I have a bad midi...when i go to check my midi drivers folders in my library its empty...does anyone know whats going on?

    I
    got your message about making sure to use the machine specific disk that came with my machine. Unfortunately, Apple no longer sells Tiger replacement disks. I've got a couple of bids out on ebay, and will update when I have news to add to this post.
    Thank you for your help, Frank!
    To be clear you called the 800 number and explained what the situation was, old machine and lost the original DVD's?
    Just checking because if you just called and tried to buy the DVD's they might tell you they no longer sell them but you aren't really trying to buy them your trying to replace the ones that are missing.
    Ebay may work but there is a certain specificity to the DVD's required which, even if they seem right, might not work.
    Good luck either way. If you get a chance when you get the DVD's I'd be interested in hearing how it all works out.

    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?

  • Does anyone know if apple's one-to-one program would be a good way to learn how to use logic pro or am I better off going to school to learn audio engineering or something?

    Of course going to school would be a good option, but I want to know if one-to-one is also a good way to learn how to use logic pro. Has anyone been through the one-to-one program for logic pro and can say that they learned how to use logic pro well because of it?

    For sure, one to one training, if given by a tutor who is capable, will hand you the means to build up self-confidence  and will therefore let you operate the hard/software in an intelligent manner, instead of going for the trial and error method which has its pro's and con's too. Once you've passed this beginners phase you will make your own decisions intelligently and then you will also start to get experience and learn even from your mistakes. Something like that in theory and the rest is up to you!
    Have a nice day

  • How do I use logic as a mulit timbre sound module???

    Whats up people,
    Im trying to trigger all the sounds in logic via a hardware controller (mpc) separating everything on separate channels. I got it to read on just one channel at a time, but multi?? Forget about it.... I read other posts in regards to this same question and have run thru the suggestion switched midi setting to auto demix etc...
    Doesn't respond if i go to another channel on my hardware and select the new instrument to the same channel in logic it still only allows playback from one channel at a time?? Huh is my theory even possible folks!?? I would think it is.
    Im trying to comprehend the instructions in the manual for the environment setup, to see if i need to make any changes their. I thrown in a channel splitter, a seq input, a transformer but i have no idea if im doing it right?? I must be slow cos to me that enviroment chapter reads like riddles! (LAYMAN TERMS SOMEONE PLEASE!!)
    If anyone can assist in this id appreciate it. Any and all suggestions are welcome.
    Good lookin out
    peace
    D.

    Greetings people,
    The latest.............okay where do i start. Well i actually followed everybody suggestion on this thread and actually as a result now understand the enviroment a little better. But i have still been unable to get my multi playback channels. I managed to get access to all 16 channels etc.
    Right now i have my physical input going thru the monitor to the channel splitter, each channel is cabled to my audio instrument(which im assuming is the multi inst i created as to represent the mpc) channels are set to all and then i have the out of my audio instrument going to the seq input. I hear my sounds and have actually triggered the internal sounds from the mpc pads no problem (did that b4 i posted)
    but now say i select midi channel 1 on my mpc, which in turn is instrument 1, double click it to get the audio window select ultrabeat, go back to the mpc and program some drums using ultrabeats sounds. Now remember all im doing is recording midi signals into my mpc which is triggering logics sounds right. okay so now, im saying i want to go to the next channel/audio instrument/ and now use sculpture and put a nice fat bass on it. so i select the patch i want hit play on my mpc hoping that it plays back the drums, but NO! now i have selected a new track it pulls over the programming i did for ultrabeat into the sculpture patch.....follow me??
    I tested logic to just record one at a time in the arrange, and it does but it records real erratic. btw my mpc is strung up thru my midisport usb which i did select in the enviroment window..check!
    I tried Mac's method of dragging the audio instrument into the arrange and selecting the track with a corresponding sub channel etc but got allot of midi feedback!!??? I know that going to settings - record-auto demix etc is supposed to do the trick, well it aint for me?? Please what am i doing wrong??
    Ultimately i want to be able to program my mpc using logics sounds via the midi channels simultaneously, and then dump it all down into logic once i am happy with the outcome. Am i asking too much for logic to be a sound source and recorder at the same time??
    I dont mean to sound naive or ignorant but i have just started using software for the first time. i use to go the hardware route using digital recorders allday but it was a simpler routing method since my sound sources were seperate(keyboards, sound modules etc). obviously now im tryint to intergrate my old style with the new, but im getting very fustrated and creativley lathalgic from this setback. Many have suggested tossing the mpc and using logic for drums, but sorry i just cant do it i love that boom bap to much.
    Anway sorry for the rambling its late and ive just spent the last 5 hours beating my head upside the g5. If anyone out their hasd a similar setup to me whether successful or not, get at me lets trade off techniques and ideas.
    Thanks again for taking the time to read the thread and offering your help, please keep it coming.
    peace

  • I am using logic to record a podcast and using soundboard to use as a playback for music and sound effects.  I'd like to soft patch sound board into logic, and still use my interface for recording audio from the other members of the podcast.

    I am using logic to record a podcast.  I have a presonus firestudio mobile for my interface so I can record several people at the same time.  I'm also using Soundboard for a playback system for music and sound effects.  I'd like to know how to soft patch Soundboard into Logic while still using the Firestudio interface to record the other members of the podcast.  Does anyone know how to do this? and if so can you tell me how to do it?  Thanks.

    Thanks. Now, since Apple failed to provide an audio in jack for their new and improved iMacs (mine has one), all I can suggest is that you contact AppleCare, since you have 90-dqy free phone support. If need be, you might reconsider your purchase, but that's for you to decide.

  • Using Logic 7.2 on a Mac Pro with Protools 7.2.1 and Mac OS 10.4.7

    I am researching purchasing a New Protools/Logic System
    Seems the version of Protools to use with the new Mac Pros is 7.2.1, which only recently came out to work with the new "Mac Pros" Digidesign has stated thhat it works with and Mac OS 10.4.7
    The latest version of Logic is 7.2 which has been out for a while....hmmm
    Is anybody using Logic 7.2 on a New Mac Pro with Protools 7.2.1 and Mac OS 10.4.7, and does it work?

    Logic Pro 7.2.2 is not compatible with DAE/TDM on a Mac Pro INTEL.
    You will see only "CoreAudio" as available choice, when trying to engage your audio hardware.
    We have to wait for any announcements in this regard, maybe at AES or DigiDays in San Francisco.

  • Can you use logic express on a mac mini for recording

    Can i use logic exprees on a mac mini for recording? Ive seen alot of 8,12, and 16 track recorders with a cd burner and it seems like a logical and more productive gues for me to buy a macmini for the same thing of recording and then I can uses logic express, a far better program for recording. can the mac mini handle the load of processing tracks and how much ram should I uses? thanks tim

    sorry, I'd like to butt in here:
    I would like to do the same thing, so I am curious about this forum and rather than starting a new one, can I get some advice on this possibility:
    Mac Mini
    1.83GHz Intel Core Duo
    2GB 667 DDR2 SDRAM - 2x1GB
    80GB Serial ATA drive
    Glyph External HD 250 Gig
    Mackie Onyx 1620 w/Firewire
    Logic Pro 7.2
    thoughts?
    The most number of tracks I could see at once would be 16.
    Here is something I am most curious about...
    Firewire Hard drive
    Firewire Interface/mixer
    Firewire camera for FCP
    to much firewire?
    Please let me know if you have other thoughts aswell...

  • Can I use Logic Pro 9.1.6 on two computers with one licens

    I have download and install Logic Pro 9.1.6 on my MacBookPro 13". I record on location with my MacBook an wil edit and arrange the music on my iMac at home. Can I use Logic Pro 9.1.6 on two computers with one licens. I'm the owner of both computers. If it can where can I find the program on my MacBook? and how to install and register?

    Hi, is  the iMac also 10.6.8? I had an iMac die when 10.6.8 was installed, it worked at first but after some You Tube flash videos the screen just locked and no mouse clicking anywhere did anything. It turned out that most older iMacs [ mine was from august 2007] have a graghics chipset that can't handle Snow Leopard, there were [are?] 77 pages on this "locked screen"topic in the Snow Leopard forum. I checked out a web site that tells you how much your mac is worth by filling in the sereal number-mine was worth only $168, I may give it to a friend for his children to play with, although that seems unholy. I doubt anyone woud buy it,the problem is now so well known that even Apple certified resellars here in the Netherlands refuse to repair them,they claim Apple will revoke their certification if they replace the faulty Graphics unit,it is also VERY hard to get to that unit in an iMac, everything is so tightly packed inside.
    If your iMac is running Mountain Lion[10.8.0] you may have to change the app store preference to accept apps from all sites,normally ML will only allow app store apps to be downloaded.

  • Using Google GWT to create (Dashcode) widgets for iBook Author  I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pa

    I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pages (for example, http://softoption.us/content/node/437 scroll to the bottom). In theory, iBookAuthor can bring in most html5, and much javascript. The technique is to wrap the html in a folder, with 2 extra files, a plist and a default png and then change the extension of the folder to ‘.wdgt’. This is the technique for making Dashboard widgets for the Mac, and Apple even have the Dashcode software to do it. So what you really do is to make a Dashboard widget, then iBookAuthor can import it.  So far, so good. And some  folk have been doing this, for example http://www.prweb.com/releases/2012/2/prweb9242432.htm http://www.panophoto.org/forums/viewtopic.php?f=64&t=10417&p=158330#p158423 However, if you start with GWT and create a single page with one button and a Hello World, compile it, and get the WAR file (I use Eclipse here)… the Safari browser and others will run it properly (even on an iPad). Then if you wrap it, a proper Dashboard widget is created, which runs properly on a Mac. Then if you go to iBookAuthor and put a custom widget in the Text, then drag it in. It is accepted by the text and shown as being there. However, if you use Preview to look at it on an iPad, it is gone (or was never there in the first place). Anyone any ideas on this? [And iBook Author seems to give no warnings.] The widget is at https://dl.dropbox.com/u/46713473/Test6.wdgt.zip I have bells and whistles that I’d like to get into an iBook!
    Thanks for any insights.
    Martin

    I do have a little to add, which might help someone. Indeed, opening a blank page and dragging the widget straight in seems good in difficult cases. But, actually, I was also able to insert successfully from the Toolbar especially to blank pages. So, it may have been something to do with the columns and stuff like that. Anyway back then the insertion would show in iBooks Author but not in the Preview on the iPad. I moved on to actual Google Web Toolkit output javascript. Basically I had three at hand to try: a Hello World with a button which went straight it, one of moderate complexity, (for example with a built in Lisp interpreter), which also went straight in, and finally a more complex one that initially was rejected by iBook Author. Author complained that there was an unsupported media file (of course, Author does not tell you which one it is, that would be too easy). [Remember, this was a proper working Dashboard widget which could be installed on a Mac]. Among other things I had read remarks about .gif files. When looking through the GWT war directory at the actual javascript etc files, I noticed there were two gifs there one called ‘clear.cache.gif ‘  and a second one called  ‘0F89659FF3F324AE4116F700257E32BD.cache.gif’. (Now, there is obfuscation so the numbers here may be different from case to case.) The clear.cache.gif did not seem to be anything special. But the other one is an animation. It is three little boxes that twinkle (rather like a waiting spinning cursor).  So, I opened that file and saved it to itself (that picks the top frame of the animation and saves only that, leaving you with an unanimated gif). The resulting widget drags and drops into iBooks Author (and seems to work properly at a quick glance). So, if you are having trouble with ‘unsupported media files’ converting animated gifs into unanimated gifs might help in some cases.

  • How to retrieve data using logical database and custom select options

    Hi all,
    I have a selection screen which is displayed by logical database PSJ and I have two select options of my own. I need to retrieve data based on both selection screen of logical database and my own select options. How can I do it?
    Thanks in advance.

    Check the following Document & Links
    1. A logical database is in fact
    a program only.
    2. This LDB provides two main things :
    a) a pre-defined selection screen
    which handles all user inputs and validations
    b) pre defined set of data
    based upon the user selection.
    3. So we dont have to worry about from
    which tables to fetch data.
    4. Moreover, this LDB Program,
    handles all user-authorisations
    and is efficient in all respects.
    5. tcode is SLDB
    good info about Logical Database. you can check the link.

    Functions for displaying and changing logical databases:
    Call Transaction SE36 or
    Choose ABAP Workbench -> Development -> Programming environ. -> Logical databases
    Interaction between database program and report:
    During program processing, subroutines are performed in the database program and events are executed in the report.
    To read data from a database tables we use logical database.
    A logical database provides read-only access to a group of related tables to an ABAP/4 program.
    advantages:-
    The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
    i)An easy-to-use standard user interface.
    ii)check functions which check that user input is complete,correct,and plausible.
    iii)meaningful data selection.
    iv)central authorization checks for database accesses.
    v)good read access performance while retaining the hierarchical data view determined by the application logic.
    disadvantages:-
    i)If you donot specify a logical database in the program attributes,the GET events never occur.
    ii)There is no ENDGET command,so the code block associated with an event ends with the next event
    statement (such as another GET or an END-OF-SELECTION).
    1. transaction code SLDB.
    2.enter name z<ldb-name>
    3.create
    4.short text
    5.create
    6. name of root node (here Ekko)
    7. enter short text (f6)
    8.node type -> data base table.
    9.create
    10 change logical DB
    riht click on ekko and insert node
    here node name ekpo
    11.create
    12. click on selections
    13. press no Should the changed structure of Z<ldb name> be saved first.
    14.select tables which you want to join.
    15.transfer
    16 now you have to o to coding part.
    17. save
    activate.
    19.click to src code
    double click on first include and activate
