Hi,
To access the MIDI ports you will need to call the Windows SDK. To send MIDI commands is relatively easy, here is an example that shows you how to send data to a MIDI controller or keyboard.
As far as input goes, this is the hard part. There are a series of functions that you need to call to open up the device, set some buffers and and possibly a callback to get notifications on the incoming data.
Reading MIDI data will not be an easy task, your best bet will be to implement this in a DLL and call that DLL in LabVIEW, there should be some code available o the web.
= "http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_multimedia_... is a link to the Windows multimedia functions that you could use for MIDI input.
Let me know if you have any further questions.

Must use Step Input Keyboard prior to using midi controller? When I attempt to use my midi keyboard conteoller for step input, it won't work unless I input the first note in each track via the Step Input Keyboard. This doesn't seem right...

Not at this time. It would also be great to have an adjustment for sensitivity too.

I want to use the sound card with LabView

Hi. Who can help me, I want to use the sound card with LabView, I have found the function but I can't use it. Thanks.

Christi,
In LabVIEW 6.1 I found some examples they use those sound VIs. They are located in \examples\sound folder. Those examples should give you a good overview how to use the VIs.
Hope this helps

Is it possible to use an IrDA protocol with LabVIEW 8.2.1 in DSP BlackFin?

Dears,
I'm building a project to communicate a DSP BlackFin 533 with a Palm E2 Tungsten between IrDA Protocol. The packaged LabVIEW installed in Palm allows to use IrDA protocol, but I don't know if the packaged for BlackFin DSP allows or not.
Is it possible to use an IrDA protocol with LabVIEW 8.2.1 in DSP BlackFin?

HT201178 when using apple bluetooth keyboard with iPad, hitting the enter/return key while typing in iMessage only adds another line not 'send' the message? is there a setting to change that somewhere?

when using apple bluetooth keyboard with iPad, hitting the enter/return key while typing in iMessage only adds another line not 'send' the message? is there a setting to change that somewhere?

Everywhere that I've checked it is not possible to do this. I would like to even do this using the vkb. I hate having to stretch my thumb all the way up just to send a message. It's messaging, not a report or email. Seems backwards. Hopefully some day Apple can add this option.

Can i use apple bluetooth keyboard with my samsung tv

Can I use apple bluetooth keyboard with my samsung tv that does not have a built in bluetooth

To my knowledge, no. A Bluetooth device will connect to something that has appropriate BT hardware.

Using PVCS keyword replacement with LabView

Has anyone tried using "fixed keyword expansion" with LabView? There is feature that you can use to replace text strings in a binary file but I've not been able to make it work for a VI.

I don't think that is going to work. PVCS has no way to know about the
offsets and size fields located in a given VI. I'm not familiar with
the option you are asking about, but my suspicion is that it is
specifically designed for a particular resource format or EXE format.
If you are looking for a solution to translate strings in a VI, there
are menu items under Tools>Advanced for Exporting and Importing strings.
The file format is pretty readable for hand translating, and pretty
easy to parse if you want to extract the strings to another form,
translate, an
d rebuild.

Oracle ADF RichSelenium class - any examples on how to use this?

Digging around the net and found that there is a class for Selenium testing ADF Rich components, namely oracle.adf.view.rich.automation.selenium.RichSelenium located in oracle_common\modules\oracle.adf.view_11.1.1\adf-richclient-automation-11.jar.
I've been searching for half a day now and cannot find any example code on how to use RichSelenium class for the life of me.
There are examples of using Selenium with ADF (http://www.oracle.com/technetwork/articles/adf/part6-094560.html) but not using RichSelenium.
Any lead or information would be highly appreciated, thanks in advance.

OK figured out how to start using this RichSelenium class and thought I'd post my findings on this thread for the sake of anyone else who wants to know. Here's my code:
-- START OF CODE
package my.richselenium.test;
import java.util.concurrent.TimeUnit;
import org.junit.After;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebDriverCommandProcessor;
import org.openqa.selenium.firefox.FirefoxDriver;
* Base test class for handling common functionality across tests - setting up web driver, retrieving URL and cleaning
* up and resources.
public class myTest {
public void runTest() {
// Create WebDriver
WebDriver myWebDriver = new FirefoxDriver();
// Setup Web Driver Command Processor
WebDriverCommandProcessor wdcp = new WebDriverCommandProcessor("http://www.google.com", this.driver);
// Instantiate RichSelenium class object
RichSelenium rs = new RichSelenium(wdcp);
// Load specific URL
rs.open("http://www.oracle.com");
// Let's do some RichSelenium specific processing
String [] someArray = rs.getAllFields();
List<String> someList = Arrays.asList(someArray);
// for loop advance
for (String temp : someList ) {
System.out.println(temp);
rs.close();
-- END OF CODE

Is there any example snippet for XPath using namespace

Hi,
I have used XpathApi class to get the XML node matching my xpath that does not deal with namespaces and it works for me. However, it does not seem to work well when I construct the xpath with namespaces (probably I may be doing something wrong example: //ns:node1/@ns:attr1).
Can anyone give pointers or some example snippet or some links to handle Xpath with namespaces.
Also if there is any better approach (Classes or framework) for handing XPath with namespaces then please let me know.
Thanks,

Onscreen piano keys stuck when using midi controller

Hi,
I am using a Yamaha PSR-172 as my midi controller. I use SoundTech's Lightsnake as my midi-usb connector. It is supposed to power the Yamaha keyboard from the usb, but it doesn't; I still need to use the yamaha power adaptor. Anyway, my onscreen keyboard displays the notes I play on the Yamaha; they colour as I play them via the controller. Sometimes they continue to make sound after I have released them, and the onscreen keys stay coloured. The sound continues until I change instruments or close garageband. There is no problem with the Yamaha PSR-172 when I use it as a stand alone instrument. Any explanation or suggestion would be appreciated.
Thanks,

No, I'm not using a sustain pedal. I'm using the Microkorg and the keys are pretty horrible (sticky and aren't that responsive), could it be this that's causing the notes to sustain indefinitely (until I press the key of the note that won't stop ringing)?
Yes, it could be that no note off (or similar/equivalent message) is being sent. You should watch your MIDI in/out on the right side of the display in the transport bar and assert if any message is being sent when you release the key. It could be that when you strike it a second time that the note off message is being sent, especially if the electrical contacts are dirty.
A new keyboard will probably solve that, yes. Unless it also has dirty contacts.

Using MIDI controller - Delay (Laten

Im using an M-Audio Radeum6 key controller connected to the computer via USB. The software for the keyboard is installed and working properly. There is a serious delay in sound being generated by my audio software from the midi controller. I realize that MIDI controllers do not generate sound, but notes - and the audio software generates the sound. How can I eliminate the latency? there should be none if everything is working properly. I have an Audigy 2 LS and believe it should be capable of playing the midi controller immediately as the controllers manual says it will. What am I doing wrong? Is there some setting, driver, connection, etc. which is not setup properly?

noiziman,
The ASIO drivers deals with digital audio signals between the software and the card, and it isn?t related with MIDI signals.
Anyway, it isn't clear from the original question if the delay comes from the MIDI device itself or from the digital audio processing, since for the later he should be using a software synth. If he's using the hardware sampler (i.e. Emu0k processor in internal SB Li've/SB Audigy with SoundFonts), the problem shouldnt have to do with ASIO.
To chek out this, i?d record in a MIDI track the signals received from the MIDI device (with the proper timming it should have, no matter the current latency of the resulting sound), and then i'd inspect the track (or it'ss event list view) looking for the singnals recorded from the controller. If the signals where received on time (that is, the timestamp matches the timestamp of an associated music event), then the latency comes from the synth. With a software synth, the ASIO settings would help with the latency (or a faster computer :-).
But if the timestamp doesn?t fit where theyre supposed to fit, then the delay comes from the MIDI cables or setup. If so, try:
) To increase the "ticks per quarter note" in the MIDI setup for the song (or decrease this, if the problem comes from overloading the MIDI network with signals)
2) Rewire the MIDI cables, i.e., avoiding chaining this controller trough other devices nor using MIDI THRU. At least i?d try pluging the controller right into the MIDI IN from the soundcard to test the latency.
3) I don't know that controller, but if it's a synchronized one, try turning off sync (or using another device for sync).
Hope this hel
ps.

Turning Region Loops On and off using MIDI controller

hi,
i got an Akai MPD24 MIDI controller today for a gig in two days...basically what I need it to do is to assign a pad on it to play a MIDI region in a loop when I press it once, then stop playing the region when I press it again. From reading the manual I've got the impression you need to use Touch Tracks, but at the moment how you go about assigning a pad to loop a MIDI region is going over my head! I'm sure this is a very easy thing to do but I'm new to this sort of stuff...could anyone give me some pointers on how to do it? Cheers.

Your gig seems to be done, but in case you still need to know and haven't figured out how to do it:
• create a Touch Track
• open it
• drop the regions on it's keys (beginning on the lower notes)
• assign all the tracks that shouldn't mute one-another to different groups
• set Trigger Mode to „Toggle Loop“
• adjust the other parameters the way you need them
I think the Touch Tracks have great potential, but editing them really isn't as slick as is should be…
