Re: please help.. mmapi.. how can i write my own controls for audio process

it is just like
for example when we increase the volume, the player
keeps playing without pausing.. i want my controller
to be able to do this.. first of all:
have you ever created a javaME music player with a volume control?
if you did one and well implemented it, you should have seen that increasing volume (in
a good implementation) never causes pausing...
so, is it possible to write
my own audio control class in j2me? and is it
possible to make it real time without causing the
player pause?second:
you can try... good luck

Is there a way to add shapes to the shape library, and does anyone make a shape library for electronic block diagrams?

Hello!
I'm trying to use Pages or Keynote to make electronic block diagrams. The shapes library looks like it would be perfect for the job, but the shapes are limited. I know I can make a custom shape, but I live with slight brain damage, which means the mouse is NOT my friend. If I try to make custom shapes, they look like a kindergartener's scrawl, so that's not a solution.
All of the online forums I've been to so far say to use Visio (ick!) and if your desired symbol is not there, make it yourself. Well, several symbols are not there, and the first paragraph explains why this is a non-starter.
I would gladly pay some reasonable fee for electronic shapes, such as amplifiers, mixers, oscillators, etc. if someone made them. But from the help file I can't even see a way to add those shapes to the Apple shape library, so I'm not sure, other than copy and paste, how to handle outside shapes. Copy and paste is pretty labor intensive anyway, but if it's my only option, well, so be it.
Any suggestions? Aside from Visio, that is...
Thanks!
Jim

Hi Jim,
When you say the "Apple shape library" do you mean the Shapes button on the toolbar in Pages?
I don't think there is a way to add to the Shapes in Pages. However, you can create a custom template with shapes that you frequently use. Save a document with your shapes then Menu > File > Save as Template...
This will be saved in My Templates folder, and you can open it with Template Chooser. You will still have to Copy and Paste a shape into the document you are working on. No way around that!
I don't use Keynote, so I may be missing something in your question.
Regards,
Ian.

I need to maintain a temperature profile for my process.Can i use PID control for this application?

Hi all,
I need to maintain a temperature for my process.Can i use PID control vi's for this application?
I have NI-PCI 6023E DAQ board.Should I need any other hardware components???
Any help in this regard is highly appreciated.
Thanks,
radhika

Hi,
Thanks for your reply.
I do have a temperature sensor and it is read by the DAQ (NI 6023E) .
Also i have a voltage input to the program which has to be controlled in order to control the temperature.
So , I am using a PID , the output of the PID should control the Voltage input so that the temperature is controlled.
Can I give the voltage input and the temperature to the PID through the DAQ and just use one more channel in the DAQ to get the output from the PID.Will that work???
I am not sure why you have mentioned SC2345,SCB68.
Thanks,
radhika

USB or FIREWIRE for audio interface?

Hi,
what will you prefer to , USB or FireWire of your audio interface?
and why?

Here's the "pecking order" for performance and stability :
1.- Internal PCI or PCIe card to audio interface. These units are the best overall, both in audio quality, low latency, and reliability. Some have built in processing cards, with which you can use instead of the computer's CPU, for audio processing tasks.
2.- FireWire audio interface. These are reliable, but can have issues if not set up properly, due to the FireWire drivers which need to be used to run these units. Some have onboard "low latency" mixing facilities, and some have CPU processors for processing audio.
3.- USB 2.0 audio interface. These are also reliable, however are more limited in bandwidth than the FireWire counterparts. This is due to the different nature of the USB audio protocol VS the FIreWire one. Still, it is not that bad for home recording.
4.- USB 1.0 and 1.1 audio interfaces. These are reliable, but not recommended if a lot of realtime audio recording is going to take place. In other words they are great inexpensive units for doing programming, sequencing, editing and mixing, BUT not so much for live audio use, or live audio recording. this is due to the limitations on the USB audio protocol architecture. It simply cannot handle low latency audio very well.

How to maintain List Of Values (LOV's) for BPEL Processes

We are integrating two systems.Source and destination systems store data in different formats. For example State is stored as a string in source and its stored as an number in destination system. In BPEL we are trying to transform this information and send it to destination system so that it understands the incoming data.
A sample of transformation we need to do is as shown below.
State in Source     Sate in Destination
Texas               1
Nebraska          2
But we have so many fields that we need to transform as we are doing for State.
What is the best way of handling these domain mappings in BPEL. I want to know is there any efficient way we can handle this in BPEL as we do in J2EE applications(Maintaining them in Domain tables and making them available for all functionalities).
We are looking to hold all these domain mappings at one place and use in all the processes we design.Can anyone suggest a better way to handle this for BPEL processes.

Hi,
I am using the lookup-xml for maintaining list of values.But dont know whats the problem unable to get the output.
Example: this is just a sample one which i am testing.
My xml file is placed in c folder with the name "StateList.xml" which contains the following info.
<?xml version="1.0"?>
<Countries>
<Country><Abbreviation>CO</Abbreviation><FullName>CO</FullName></Country>
<Country><Abbreviation>CT</Abbreviation><FullName>Connecticut</FullName></Country>
<Country><Abbreviation>ID</Abbreviation><FullName>Idaho</FullName></Country>
<Country><Abbreviation>NJ</Abbreviation><FullName>New Jersey</FullName></Country>
<Country><Abbreviation>AP</Abbreviation><FullName>Andhra Pradesh</FullName></Country>
</Countries>
And in BPEL, in the transformation i am taking the input and assigning this lookup value to the output variable as follows :
<ns1:result>
<xsl:value-of select="orcl:lookup-xml('file:/c:/StateList.xml','/Countries/Country','Abbreviation','FullName',/ns1:HelloWorldPavanaProcessRequest/ns1:input)"/>
</ns1:result>
But unable to get the result.Kindly help me out in this.

Is it possible for a process to participate in two separate clusters

Is it possible for a process to participate in two separate clusters? For example if our application would like to get market data in one cluster that has a separate multicast address, and post order in another.

The easiest way for a client to access multiple clusters is via Coherence*Extend:
     http://wiki.tangosol.com/display/COH33UG/Configuring+and+Using+Coherence*Extend
     The client would not be a member of the cluster, instead it would connect to the cluster via a proxy node that is in the cluster. Using <remote-cache-scheme>, you can configure a cache to point to one proxy (in cluster A) and have another cache point to another proxy (in cluster B.)

Advice Needed for Audio and MIDI Controller Software

I am hoping someone may be able to give me advice on how I should approach my problem.
I am currently running a live show with audio backing tracks and a small 12 par lighting system. The light system can be controlled via standard MIDI. I am using iTunes to play back sets of backing tracks, and manually controlling the lighting system using a dedicated foot controller.
What I would like to do, is be able to use software to simultaneously play audio files and perfectly sync the lighting (fades, shots, etc. via midi) with the audio track. Ideally, I would be able to have the audio/lighting paired as discreet entities that could be grouped into sets.
i.e.
Audio-MIDI_1 = Audiotrack1 would always be paired with Lightcontroller_MIDI_events1
Audio-MIDI_2 = Audiotrack2 would always be paired with Lightcontroller_MIDI_events2
Audio-MIDI_3 = Audiotrack3 would always be paired with Lightcontroller_MIDI_events3
I could the create a set of Audio-MIDI_x tracks which could be triggered in any order.
I would like to have to option to be able to activate a single track, or have a complete group of tracks activated sequentially (but be able to stop the and start the group as needed - you never know what will happen in a live situation). It would be nice to have a time-line UI as well.
Now the final requirement: it should be able to run on a PISMO PowerBook. <cringe>
I hope I am not too confusing.
I am thinking MainStage would not be the software for this task as Leo is not an option for the Powerbook.
I have looked at QLab and showcontrolpro, but I don't think theses are right for me either.
Any help or suggestions would be greatly appreciated.
TIA

Gary,
With a Pismo you really are confined. I've been using some software from Alien Apparatus called Solo Performer Show Controller (www.alienapparatus.com) and it has a timeline to sequence lights where you can run 32 channels of midi or dmx lighting. The only setback is it needs at least a 1 GHZ processor. There may be a company like Sonnet that has an upgrade for your processor.
The software is able to run backing tracks, send midi controls to effects units or other software, send hotkeys for apps, synchronize lyrics in a window or on an external monitor, controls a dmx fog machine, and also has a six button usb foot controller which can be configured for many things such as scrolling your songlist to select the next song, change volume of tracks, change a light scene, send a hotkey, trigger samples, etc. It is a bit pricey at just under 600 dollars but the foot control is durable, the company has excellent support and they listen to users to add features to the software.
Hope this helps

Fetching records in a block(db) for mass processing

My user interface inputs commit frequency for intermittent commits. We reference this to # of records processed & then issue commit. [whilst processing against millions of records]
Now, we want to process all records belonging to set of data blocks to avoid contention issues (gc/ other locking issues) & then issue commit.
So the question is, how do I query records belonging to a particular block OR identify those blocks that hold my data.
Any pointer is greatly appreciated.
thanks
Kiran.

This is needed for a DW instance wherein we select recordset from a OLTP instance running 4 node RAC. The user then inputs a condition based on which the records are selected.
We are commiting based on parameters defined by DBA's - the commit frequency. This increases contention especially if the records are stored in contiguous location. Add to this the RAC, the GC traffic is huge.
So what we want to do is to grab all the records in a particular block & read the whole block & then process to DW. I was looking at a query that can get me the block# involved in this process.
Could you clarify:
Is it the OLTP that is on RAC, or the DW, or both ?
Which type of contention - can you show us the critical wait information - and is this on the OLTP or RAC system, and is it the OLTP or RAC system where the GC traffic is huge ?
You seem to be asking how you can specify a query in an OLTP system that is going to visit many table blocks - but "pre-sort" the data in some way so that it visits each table block only once, and visits the table blocks in order so that you don't revisit the same table block and run the risk of extra interconnect traffic on the OLTP system. Is this a correct interpretation of your requirement ?
Does your transfer process do something like:
counter := 0;
for r in (select from OLTP system) loop
    insert into DW system values (r.thing....);
    counter := counter + 1;
    if counter = {limit} then
        commit;
        counter := 0;
    end if;
end loop;
commit;Regards

System exec subvi. can't access block diagram for positioning

OK I am back!
my first issue is that for some reason I can no longer attach files here for you all to see...
Second and more to the point is how can I tell the system exec.vi to open where I want it too when access to the block diagram is password protected and I can't seem to make any property nodes for the vi either.
I am using this vi to call the OSK (on screen keyboard) for touch screen panel.
I would have sample to show but see number one...
Solved!
Go to Solution.

Thanks Dennis - again
after posting i made an executible of the project as it stood and put it on my touch panel.
I found that it called it OK and I could just moveit around and resize it as i wanted, just once. then whenever i called up the OSK it was where i left it and the same size.
While this may be a small pain to the end user, I think i will keep it like that for now and just let whoever they are deal with it as part of the initial program protocol.
but what about not being able to add attachments here? do I need an adult?

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel?

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?

No. The Label Visible property is separate for the front panel control label and the block diagram terminal label.
How did you start out with the block diagram's label not being visible? Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default. Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it. I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.) I've gone to the BD and right clicked to show the label. Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing. When I add some text to the label, at that time, I find both the BD and FP labels become visible.
Are you dealing with controls that have empty labels to start?
Good programming practices:
1. Always have a name for all of your controls, never use and empty label by deleting the text in the label.
2. Make the labels unique. For example, don't have two controls both called Stop. How do you know quickly know which terminal relates to which control?
3. Always show the labels on the block diagram, so you know the function of a control's terminal. If you want to hide the label on the FP, that's okay.
4. If you want a different label to appear on the FP than whatever you actually called the control, then use the caption. You can hide the label and show the caption. This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language.

Terminal images for arrays on block diagram

I had always know that the thickness of the wire is representative of the size of the array on the block diagram (Thin wire, scalar, thicker wires, larger dimension arrays)
I never noticed before that the terminal on the block diagram contained the [ ] symbols to indicate it is an array. But also, the larger the dimension of the array, the thicker the brackets are, up to about 5-D. (Probably because I rarely need a 3-D array, and large than isn't any practical, logical reason for a 4-D or larger array.)
However, looking at the image of the terminal, the shaded area containing the outgoing or incoming triangle actually obscures one bracket or the other.
While I wouldn't want the terminal to get any larger (which is why I don't like the icon view, it is way too large), it seems like the terminal should show both the opening and closing brackets to indicate an array rather than obscuring one.
Any comments?

Definitely keep the arrows. They are what tell me the direction of the terminals.
As I was saying in another post, there is nothing intuitive about the thick border/thin border differences to tell whether the terminal is a source or sink. I like that they are a bit different, but if you put them side by side with no wires and no arrows, I couldn't tell you which was which.
As for array size, as Christian says, if I want to know the type/dimensions of the array, I'll use context help. I just thought it was interesting (and I had never noticed it before) that the array size was encoded in the image as well.
I myself wouldn't mind if the terminal grew 2 or 4 pixels wider, but I can completely understand how it would bother a lot of people.
I think in the current image, too much is obscured by the arrow and its background, even for the scalar type. Actually, why is there a light background behind the arrow at all. That is the real source of the problem. Eliminate the background, and move the arrow over to the edge, and you can see everything without extra shading and without causing the terminal to grow.
See below:
1. Terminal size maintained.
2. Direction arrow maintained, just slightly moved.
3. Goofy shaded background removed.
