Extra notes on virtual instruments

So I'm getting some extra notes on my virtual instruments. The region length is specified at 4 bars but on play back I'm getting the first notes of the region on the 5th bar (the region stops at the end of the 4th bar). There is no midi date hidden in the region and this occurs whether the region is looped or not. When I extended the region through bar 5, the notes ARE NOT heard (the desired result but the wrong region length). What gives, any answers?

Is the loop unquantized? If the first note is before earlier than the first bar of the region, it will playback in cycle mode when it come around again. Does it play when set to 5 bars if you wait for the loop to come around?

Using "Stomp boxes" with virtual instrument guitars?

Hi,
Just "upgraded" to newest ver of GB. With the previous ver I could create a track using a virtual guitar and then edit and add stomp boxes, amps, etc to configure the tone the way I wanted.
I don't see a way to do this in the new ver of GB. I can add stomp boxes to a track that uses a real guitar, but not to virtual instruments.
Any suggestions on how to do this?
Thanks,
Dan

Hey, Paul,
I totally agree: quick-swipe MIDI is the #1 feature I've been hoping to see in Logic for several years now... fingers crossed for the next major release.
And it really shouldn't be a complicated feature to implement. As you mention, there is the issue of note on/off messages, as well as possible program changes and controller messages, etc., which might cause undesired results if regions were cut arbitrarily.. but... that potential for inconsistency exists every time we cut a MIDI region with the scissor tool as well. If the quick-swipe tool just duplicated the behavior of the scissor tool, I think it would be extremely useful in most cases.
Don't forget to file it as a feature request!

All strings virtual instruments not working!

everything was working great in my song, but all the strings virtual instruments randomly stopped working. the notes cut off after a quarter of a measure. if i change that track to any non string instrument, the notes play out the way they're supposed to. i've tried creating new string instruments and i have the same problem, i have no idea how i caused this or how to fix it. help please

never mind, the problem stopped after i restarted my computer again. thanks to everyone who didn't help!

Looking for a labview virtual instrument program we can modify

Hi, I’m looking for a canned labview virtual instrument program we can modify for the OMB DAQ 55 from Omega to measure three temps and control three DO. I have the driver at:ftp://ftp.omega.com/public/DASGroup/products/OMB-DAQ5455&56/ The driver is labviewpdaq5xsetup.exe. I have the OMB DAQ 55 from http://www.omega.com/pptst/OMB-Daq55.html with a USB interface. I am trying to set it up to control a 24V electric valve. I’d like it to measure temperatures (5 separate temps), allow a set point to be programmed for three of them and turn on and off a DO based on the temperature. PID is not required yet. Maybe in the future… We have labview 7.1 and 8.0 but my colleague prefers 7.1 Do you have an labview VI programs that you can share that will do this with the DAQ 55? If you have something that will be close, we can modify it. But starting from scratch will likely mean we can not get this done in time for a project test. Simple set point and control is all I’m looking for… I’m new (my colleague knows it better than me, but has less time) to labview and do not have the resources to learn it from scratch to figure this out. Is there something you have I could modify? Can you help. Or are there canned programs you have that will do this? Labview is the preferred language. Thanks. Attached is what Omega shared with us, it might help…it’s a screen capture from a similar program, but far from the mark.

Hi vestel,
These discussion forums are more geared for questions - not necessarily having everyone else code for you.
You have a few options if you want code.
1) Look at the shipping examples that come with LabVIEW. This will give you a starting point from which to ask questions.
2) Look at the Instrument Driver Network that exits on National Instrument's Web site. Here are all the Omega instrument drivers listed.
3) Look at the list of Alliance members who you can pay to develop your code for you. Look here.
I hope this helps,

Program associated with the creation of a virtual instrument of Lab View. Please help me

I have a question with program associated with the creation of a virtual instrument of Lab View. 1.Create of virtual instrument based on the NI 9401 module fitted to the chassis NI Compaq DAQ (Ni-cDAQ-9172). Creating a virtual tool needed to implement the following counting impulses in impulse series, visualization of data through a digital indicator, comparing the number of impusite with pre-set value, that value can be assigned by the user. Indicator light when reaching in reaching the set number of pulses, the opportunity to reset the meter of a button on the front panel. Switch to digital output in reaching the set number. I hope someone can help me.
Solved!
Go to Solution.

What is your question? You've described what the program is supposed to do, but it's not clear what you're asking about. Do you need help getting started? If so, have you gone through the LabVIEW tutorials? You and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free. Have you looked through the many examples that ship with LabVIEW for data acquisition?

Call LabVIEW Virtual Instrument through ActiveX Server from C/C++

I am trying to access a VI by C/C++ almost identical to the reference example that can be found on this site for Visual Basic. However, somehow, I am unable to succeed to use the ActiveX Call() function. The program always crashes, whatever I try. Because the Visual Basic version works without any problems, I hope someone can point me the error in the code.
Thanks!

This may not be the easiest way. Although i have not used _variant_t. But it seems like your VARIANT type is VT_EMPTY for everything. You need to build up an array of variants with correct type, that matches the type of control you are assigning data to like VT_INT for int numeric, VT_BSTR for string control etc
VARIANT paramNamesVarArg, paramValuesVarArg;
SAFEARRAY *paramNames, *paramValues;
::VariantInit(&paramNamesVarArg);
paramNamesVarArg.vt = VT_ARRAY | VT_BYREF | VT_BSTR;
// create safearray of strings
SAFEARRAYBOUND rgsabound[1];
rgsabound[0].lLbound = 0;
rgsabound[0].cElements = 1;
paramNames = SafeArrayCreate(VT_BSTR, 1, rgsabound);
paramNamesVarArg.pparray = &paramNames;
long index = 0;
_bstr_t paramName = "Numeric";
BSTR *bstrVal;
retVal = SafeArrayPtrOfIndex(paramNames, &index, (void **)&bstrVal);
*bstrVal = paramName.copy();
//do the same method for paramValuesVarArg
::VariantInit(&paramValuesVarArg);
paramValuesVarArg.vt = VT_ARRAY | VT_BYREF | VT_I4;
rgsabound[0].lLbound = 0;
rgsabound[0].cElements = 1;
paramValues = SafeArrayCreate(VT_VARIANT, 1, rgsabound);

VARIANT *dispVarVal;

Is it possible to querry all of the Virtual Instruments in a VI using the ActiveX Server Virtual Instrument Class?

Is it possible to querry all of the Virtual Instruments that exist in the Front panel of a VI using the ActiveX Server Virtual Instrument Class? I can't seem to find a method or property that returns all the Instruments I may want to control from another application.
I wish not to have to reference to the VI to figure the ControlName by looking at the VI FrontPanel.
But rather have a prop that exposes the strings of all the Instruments.
Example:
allinstr=ObjectVIInstrument.VIControlNames
Object.SetControlValue(AllInstr(1),value)
Thanks.
-Abe

Abe,
There is a VI method called "Get All Control Values" that returns an array of {name,typedesc,flatstrvalue} but this method is not exposed to ActiveX interface, most probably because type descriptors and flattened strings are data format internal to LabVIEW.
However you can make a subVI that inputs the target VI name and returns the name of all controls on the Panel invoking the internal method. Then you call this VI via ActiveX to retrieve the list of Front Panel controls of the target VI.
LabVIEW, C'est LabVIEW

Error code -50 when opening Logic virtual instruments

I'm getting an error code -50 when trying to open any of the Logic's virtual instruments, VIs from other brands open without a glitch.
I have searched the support forum but no results came back.
Please help !!!
Thanks in advance

The plugins access the key to check they are authorised to run (remember, the main plugins were separate purchases once upon a time). Obviously, if you are on a USB port/hub that's not agreeing with the XSkey, then communication is unreliable and can take the form of a number of different effects on your system.
That -50 error probably means the plugin failed to load, as the communication with the XSkey failed during the initialisation process.

How can I do a simple MIDI track (no virtual instrument)?

I'm having the hardest time trying to figure out how to do a simple MIDI recording. So far as I can tell, I can only record MIDI data if I select a virtual instrument for the MIDI track. When I used to use Cubase, I could just record the straight MIDI signal without having to select an "output" for it, and then load up whatever instrument I wanted to use later. Can I do that with Logic 9? I record some MIDI stuff live, and I'd like to not have to bog down my machine with running live virtual instruments.
Mainly what I'm doing is recording the MIDI data of a set of VDrums, so that when I get to mixing later on, I can trash the crappy v-drum sounds and use DFH Superior for my drums.
Much thanks for any advice ahead of time!

Cool. I'll check this out and see if it's that easy for me. i feel like I tried that, but it wouldn't show any signal until I inserted a virtual instrument. I'll try again and make sure I do it right.
What we're doing while playing live is using the Roland Vdrum sounds live (and recording the vdrum sounds themselves, as well), and also recording the MIDI data to a MIDI track. Later during mixing, I'll mute all the vdrum audio and pipe the MIDI track through DFH Sup. I have a v-drum preset I can then apply so that the MIDI data will trigger the software correctly. In the studio, I use DFH and listen to it during recording.

5900 PR virtual instrument code

Hi all
I have a panametrics 5900 PR (pulser receiver) which is a computer controlled device. Panametrics provided me with the driver and an old virtual instrument code. The code can only work for operating systems up to windows NT (98 and below). Currently, I don’t have access to Windows NT but I have windows XP instead. Is the current code going to work with windows XP? (I think that some specific codes, depending on their usage of registry files, can work in most of the operating systems).
In the mentioned code, when I try to open it, my labview version( ver 9) says that these codes are too old to open (ver 4).
Can anyone help me please...

There is no way for us to be able to tell you whether it will work under XP since we have no idea what the driver does. That's something that's better asked of the vendor.
As for the LabVIEW code itself, if you cannot get a newer version of the code then you can upload the code here and someone can save it for you in 8.x so you can open it in 2009.
Note: in the future, please stick to one thread for the same topic.

Virtual Instrument loading problem

Has anyone else encountered this in 8.01 please? It's intermittent but frustrating.
I have a default project that contains, amongst other tracks, 8 virtual instrument tracks. Since 8.01, I keep getting a situation where I select a track, pick a preset from the library, record a few bar on a loop, switch record off but keep the looped recording playing, select the track below (track name box turns lighter grey), go to the library and pick another preset - only for it to overwrite the instrument on the previous track instead of load it into the new track!
Anyone else getting this? If it's a factor, I usually start with an arrange window screenset that doesn't show the library, then switch to another set with the library already open using the number keypad when I want to access new sounds - and then switch back to the other screenset to reveal more arrange window space again..
So far I haven't lost anything important, but can imagine editing a sound on one track and then accidentally losing it before it's saved.
Undo doesn't seem to take you back to the previous preset either.
I'm using 8.01 and Tiger on an 8-core Intel Mac.

Sorry if it's not too helpful, but all I can say is that VG2 is working fine as an instrument on my intel Mac Pro.
A quick glance at the 'info' screen tells me it's version 2.0.0.419
I'm still on OS 10.4.8 as well, since I've been too busy to attempt the 10.49 update... Maybe that's a factor as well.
good luck with it.

Concerning midi data in GarageBand for iOS: can we copy midi data from one virtual instrument to another?

Concerning midi data in GarageBand for iOS: can we copy midi data from one virtual instrument to another?
For instance: I play my "lucky take" on the virtual piano, and now I am curious how it would sound on let's say a organ. Normally I would select the midi content out of the piano track and copy it into the organ track. I cannot figure out how to do this in GarageBand for iOS. Is there anyone out there with a solution?
Thanks!

It is limited, how you can move regions between tracks. Basically, you can move between tracks with the same touch instrument. See the help: http://help.apple.com/garageband/ipad/2.0/index.html#chsec12c15d
Move a region
Drag the region left or right to move it forward or back in time. Align the left edge of the region with the bar or beat on the ruler where you want it to start playing.
Drag the region up or down to move it to another track with the same Touch Instrument. You can also drag regions between Keyboard and Sampler tracks, and between Audio Recorder and Guitar Amp tracks. Smart Drums regions cannot be dragged to another Smart Drums track.
If you move a region so that it overlaps another region, the overlapped part of the “covered” region is deleted.
Paste a region
You can paste a region you have copied, or paste an audio file from an app that supports copying audio to the clipboard. GarageBand supports 44.1 kHz sample rate, 16-bit depth uncompressed audio files.
You can paste copied regions to another track with the same Touch Instrument. You can also paste regions between Keyboard and Sampler tracks, and between Audio Recorder and Guitar Amp tracks. Smart Drums regions cannot be pasted to another Smart Drums track. Audio files copied from another app can be pasted to Audio Recorder or Guitar Amp tracks.
Move the playhead to the point where you want the region to start.
Tap the header of the track where you want to paste the region to select the track.
Tap the track where you want to paste the region, then tap Paste.You can also tap an empty area of Tracks view, then tap Paste. In this case the region is pasted into the currently selected track.

Logic does not recognize virtual guitarist vst plug in

The Virtual guitarist program instruction manual is very vague and I have no Idea where to put the downloaded folders so that logic will recognize them when I upload the program.

Thanks for responding, I have the VST wrap installed and it works fine with other virtual instruments but for some odd reason I can't get the Virtual Guitarist to appear on my instrument selection in Logic

The storage where the virtual hard disk is located does not support virtual disk sharing

Hi everyone,
I deployed 2 hyper v vitual machines a while ago, and i did that because I needed to test my current game Project, which is an
online game. However, i've had some problems with my Windows installation then I had to reset the pc by making it a refresh
install. I still have the hyper v virtual disks, but i cannot attach it to a new hyper-v virtual machine. it pops up this message:
"the storage
where the virtual hard disk is located does not support virtual disk sharing". I dont know anything about virtual machines, so I
didnt know I had to make the disk sharable. How can I force to attach the hard disk to a new hyper-v? I dont want to go t
hrough the whole proccess of installing the operating system all over again and updating it....
Any help is greatly appreciated!
Thanks in advance,
Romulo Romero

Hi MrDebugging,
>>
When I Try to add a SCSI Controller, and then I click browse to add a UNC I get this:
C:\Users\Public\Documents\Hyper-V\Virtual hard disks\ClienMachine.vhdx
but I tried placing in different location, and the same problem occurs!
By the way, Im not on a server , I am a domestic user and I am running it on my
Windows 8.1
According to the error message , it seems that it is not a permission issue .
The VM is Gen 1 or Gen2 ?
Generally the error message occurs when you enable "shared vhdx" on standalone/client hyper-v host :
Please try to attach the VHDx file to IDE controller if it is a Gen 1 virtual machine (because only the SCSI controller has the option "virtual hard disk sharing" and Gen 1 VM only can boot from IDE )
All in all , please do not use this feature without CSV or Scale-Out File Server with SMB 3.0 on file-based storage .
If it is not the case , please detail steps what you did .
