No signal from a Roland SPD-8 drum midi controller

Hello!
I've just purchased a Roland SPD-8 drum MIDI controller. It's quite old, so I've had to get the MIDI to USB converter to connect it, but my computer is picking it up.
No matter what I try, I can't get a signal from it in Logic Pro X. I have a USB MIDI keyboard which works perfectly after being plugged in, but this is one's impossible! I'm lost.What are the correct settings for this? What have I missed??

Spotlight doesn's search Library folders, maybe that's why you don't find anything. Take a look at these two folders and remove anything that you don't need (i.e. remove anything that you don't know - in a basic setup, there should be nothing in there):

How do I get signal from my Roland Fantom G8 to Logic Studio or GarageBand?

My computer recently crashed, and since then I have not been able to record any music into either Logic Studio or GarageBand. I need to get back up and running ASAP, as I'm in the middle of recording music for 5 different projects. Here's all the gear that I have:
-1 Roland Fantom G8
-1 iMac with Logic Studio and GarageBand
-1 M-Audio Fast Track Ultra
-2 Rokit KRK Monitors
-1 USB cable
-1 midi cable
-2 1/4-inch cables
-2 1/4-in to XLR cables
The 2 1/4-inch cables run from Balanced Outputs 1 and 2 on the back on the Fantom G8 into Inputs 1 and 2 on the back of the Fast Track Ultra. The 2 1/4-inch to XLR cables run from the back of the 2 KRK monitors into Outputs 1 and 2 on the back of the Fast Track Ultra. The Fast Track Ultra is powered via USB cable that runs into a USB port on the back of my iMac. The midi cable runs from the "Computer" port on the back of the Fantom G8 into a USB port on the back of my iMac. This is the exact set-up I had before my computer crashed, and I was able to record just fine. When I open up the audio preferences on either Logic Studio or GarageBand now, it recognizes the Fast Track Ultra; however, it does not recognize the Fantom G8. What I'm trying to do is get signal from my Fantom G8 into both Logic Studio and GarageBand. I also want that sound to then project through my KRK monitors. I also want to be able to record audio and midi. Please help me!!!

I used the Fantom for several years and did exactly what you want to do. I simply plugged my Fantom into a channel on my mixer, in your case the 003. I ran a firewire out of my mixer (Presonus Studio Live) into my computer using Logic Pro X. Then I just assigned that incoming channel to a channel strip in Logic. As an example I used stero channel 9/10 on my mixer, (plugged in the Fantom here). Then the signal went via my mixer firewire to computer running Logic. I assigned my channel strip input to channel 9/10.
Does this make sense?
I just sold my Fantom last week and purchased a new Yamaha Motif XF8. Now I am trying to figure out the same thing on it.

How to receive signal from Roland RD300SX in Logic Pro 8??

Hello everyone,
I have problems with setting Logic to receive any signal from my piano - Roland RD300SX.
I have installed the drivers for the piano and was hoping that Logic will simply "see" it, but unfortunately it doesn't.
I have been looking for information in the Logic manual, clicking and unclicking many options for the last few hours and nothing seems to work.
When I enable input monitoring all that happens is to receive signal from my built in microphone.
I know that the USB cable works well because when I go computer information I can see Roland being plugged in to one of my USB ports. So this must a Logic setting problem...
I will be extremely grateful for any information and help!!
Thank you in advance!!
All the best,
Natali

Sampleconstruct thank you for your answers, I finally found the solution.
The Roland was not appearing in the Audio Midi Setup and it wasn't recognized until I changed one setting in the piano itself. Despite the fact that I had a CD with the USB drivers which were set up in my computer, it finally worked when I switched the USB driver setting into the "Generic" one (which means that it doesn't use the drivers from the provided CD but the ones of my OS). I don't know why it prefers the OS drivers since there is a CD provided especially for that reason, but the most important is that everything works now!:)

In Garageband, why won't the Roland HD3 V-Drums hi-hat trigger any midi at all? (It works when it's used as audio)

My drummer bought the Roland HD3 V-Drums recently, and I bought a Mac Mini (to record on Garageband).
When we record as audio from the V-Drums (using an audio interface) everything seems to work fine - but (of course) we can't change the sounds etc as it isn't midi (and we want to use midi).
When we record as midi from the V-Drums (using a midi to USB cable) there are two major problems. Firstly, the hi-hat doesn't pick up at all - despite the fact it works when it's used as audio. When the hi-hat is hit, it doesn’t trigger any midi at all. The second is that the drums occasionally trigger a double hit. This issue I can get over (though it is annoying and it shouldn't happen) as I can manually delete any extra hits.
I wouldn't expect two expensive pieces of kit (Apple Mac and Roland V Drums) not to work perfectly on something so simple. Please can you advise me of how to resolve this?
(For info, I've emailed Roland the same issue too.)
Thanks.

While connected to GarageBand hold down Variation and 7 on the HD-3 to reassign MIDI codes. Garageband does not recognize the HH "edge" codes so I changed both of these (HH OPEN EDGE and HH CLOSE EDGE) to match the value for the "bow". With the HH pedal down, hit the center of the HH pad, the screen should say HH CLOSE BOW. Remember the code, then hit the edge of the HH pad. The screen should say HH CLOSE EDGE. Use the Up arrow button to set the value for the HH CLOSE BOW. Repeat the same steps with the HH pedal up so HH OPEN EDGE uses the same code as HH OPEN BOW. To reset any pad to factory value hold down up and down button at same time. Hope this helps!

Wireless signal from iMac to TV?

I have a new 20" iMac G5 isight on the way and have a question. Has anyone tried to hook up the iMac (or other mac) wireless to your TV. There is products like this www.amazon.co.uk/exec/obidos/ASIN/B000068TYR
ref=erra_acc_dp1/026-6032989-4654855 that will send a signal from your antenna to your TV wirelessly. I thought mabye in combination with a TV tuner like EZ there would be a way to get the signal from the mac to the TV. That way I dont have to drill a cabel-hole in my livingroom floor down to my office to enjoy FrontRow on my TV. Or is there any other solutions/suggestions?
(And i dont think there will be an Airport Express A/V launched next week... though I wish!)

You should be able to connect your ATV directly to your iMac using Internet sharing, but you can't use the same NIC that the iMac is using for its connection. If your iMac is connected to your router by wi-fi, you can share the Ethernet port with the ATV. If your iMac is connected to your router by Ethernet cable, you can share your iMac's AirPort with the ATV.

Getting Started with Labview.pdf ‏901 KB

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.

How to compare signals from two different .tdms files?

i'm developing a lie detection system in labview.so inorder for that i need to compare the threshold physiological signals from the .tdms file with the signals i acquire continuelsy from the subject for each question asked.i use respiration monitor and heart beat monitor together with the sensorDAQ to acuire the physiological signals.so which are the function i should make use of?i have the following toolkits
1. advanced signal processing toolkit
2. adaptive filter toolkit
3. digital filter design toolkit
4. biomedical toolkit
please give me advise on this.
thank you.
Solved!
Go to Solution.

Lie detector systems (polygraphs) generally work by looking at the physiological responses to the own subjects baseline, and do this in real-time. You could use a file that represents the stored "baseline" for the subject, but the overall environment, circumstances, general state of the subject, etc. may not be similar enough to easily see subtle changes.
From the stored file, you might determine a set of parameters or thresholds that indicate "normal, relaxed" for each signal. You could read the file into your LabVIEW program, process each channel, and save these parameters. Then when you have the new data, you can read the new data file in and process it in a similar way and then determine whether the parameters are outside the limits that you established for a "lie".

How can I tell if signals from two devices are truly synchronised?

Hi there,
How does one check that signals from two devices (two separate devices in a single X-series chassis) that should be synchronised actually are? I am using a PXIe6361 and PXIe4331 on a PXIe-1073, with Labview 2001 SP1 64-bit. All devices are using the Sample Clock from the 4331 device, and an AI Start Trigger, so they should be synchronised.
I thought that writing the signal data to file and checking the time stamp for each column of data would be the most accurate, but I have been told that timestamps are software created and therefore don't reflect the actual time that the signals were acquired by the hardware. When I do this, the timestamps vary by up to 150ms which is larger than I expected.
If I set the x-axis of the waveform graphs (on the GUI) to "Time" then it appears that the first data sample is taken at different times for the two plots (one plot per device).
If I set the x-axis of the waveform graphs (on the GUI) to "Ignore time stamp" (so that the x-axis just starts from 0 rather than a date-time) then the first data point occurs at "0" for both graphs. However, I'm not sure that this reflects the actual alignment of the signal.
What is the best way to check if signals collected on different devices in the same chassis are actually synchronised?
Thanks,
Claire.

Hi Lynn,
Thanks for your help and for sending the demo.
I understand the concept of how the signals will look if they're not synchronised and your demo shows that nicely. I guess I have been perplexed by someone else telling me that the timestamps in the output file (and following from that I assume timestamps on a waveform graph) do not give an indication of whether signals are synchronised. The reason they gave for this was that the timestamps are manufactured by the software, not the DAQ hardware. They suggested that I put the setting "ignore waveform timestamps" on my waveform graphs, and then check that both signals come in at the same time (i.e. both start at zero), but I'm not convinced about this.
When I use an analog trigger, neither the timestamps in my output file or on the two waveform graphs are synchronised. If I don't use the trigger, then there is far less disparity in the timestamps in the output file. I've attached two output files here, and my VI.
This is my first attempt to synchronise a voltage module and a strain gauge module on an X-series chassis, so I want to make sure that I'm achieving the best synchronisation that I can, and the difference in behaviour with and without the trigger worries me.
Thanks,
Claire.

Extreme Base station can't extend signal from Mini desktop ?TCP/IP settings

I have a Mac Mini connected to DSL via a lynksys 8 port workgroup switch. I had 6 rooms in my house connected to the router by ethernet wiring. Worked great for several years. Now 2 rooms cabling seems to have gone bad (mice or squirrels, maybe). To avoid rewiring the connection outlets or pulling wire again (Ugh!), we bought an extreme base station. It transmits the internet signal fine when connected to the ethernet network (roaming), but I cannot get it to allow clients to access the internet in WDS mode.
The base station is in a central location where there is not an ethernet jack. It picks up the airport signal from the Mini (with extreme card and yes, I have the MAC address of the Mini chosen).
Internet connection is "shared" on the Mini and the laptops have no trouble accessing internet within close range of the Mini. The laptops can't access the internet through the base station. I suspect it's how the TCP/IP is assigned. I have tried every possible combination in the Airport Admin Utility.
In the WDS diagrams, it always shows 2 or more Base stations, never a Desktop and a Base. Are these incompatible?

...but can't figure out how for the Mini....
When you select "Share your Internet connection with AirPort-equipped computers," click AirPort Options to give your network a name and password.
Since they are the "same" network does it matter?
If one has no encryption or is using weaker encryption it will be the weak link for others to access your entire network.
Normally, if you want to seamlessly roam between the 2 wireless networks, ensure that they are using the same network name (SSID), same encryption type, same encryption level, and same encryption password. However any wireless device connecting to the Mac mini's network will be on a separate subnet.
Now I've got to figure out how to get files off the Office Desktop from the laptops, should I set up afp for airport or ethernet?
Enable Personal File Sharing on the Desktop.

Powerbook G4 Can't "See" Wireless Signal from Ubee Modem/Router

I was given a G4 Powerbook while out of town and it found the wireless signal in an apartment complex and a major airport just fine. But upon returning home it can't "see" the signal from my (Time Warner, Road Runner Extreme) Ubee modem/router. My Mac Mini's Airport sees the Ubee wireless signal fine, but the older Powerbook G4 can't. (The Airport signal in the menu bar has "bars" but they are grayed out.
Can an older G4 connect with the newer Ubee modem/router? Are there security settings that will allow this?
Tx,
WK

CRMDVM -- Thanks for the helpful info -- you are probably right on both counts:
The apartments where I picked up a signal is in an "old folks" apt. complex, meaning the router I was picking up was probably old -- compatible with the G4 lineage. And the Atlanta airport probably has a wireless system to allow the vast number of old and new computers that people carry to connect.
My Mac Mini connects via WPA2 Personal security code, and I set the G4 to the same security (in the Network preference pane) but still nothing. The Airport wireless icon in the menu bar is still grayed out -- it isn't the "blank" icon as when Airport is turned off. It has the wireless wave lines in the icon, but just grayed out.
Maybe the G4 is just too old to "see" the newer wireless signal from the new modem/router.
Thanks again for your help -- you definitely provided more than I knew. (btw, I'm just above you in Union County in Stallings).

Is it possible to get 2-ch signals from TDS2012 oscilloscope at the same time with LabVIEW "7.0"?

Hi, everyone.
I've been trying to get the signals from 2-ch of Tektronix TDS2012 oscilloscope at the same time using IVI connection with LabVIEW "7.0"
I've already searched this developer zone for the answer.
I've tried the famous example: "IviScope - Acq Dual Wfm Edge Triggered.vi"
and it gave me the error message like:
Error -1074110451 occurred at IviScope Initialize With Options.vi
Possible reason(s):
Driver Status: (Hex 0xBFFA600D) Primary Error: (Hex 0xBFFA600D) The Config Server module is not present on the system.
I think I've installed all~ the required softwares for IVI. For example, ICP 2.2, IVI engine 2.0.46, and tktds1k2k ivi (instrument driver for tds2012, in fact this one is for LabVIEW "7.1"... :-P)
TDS2012 and my computer is connected through HPIB(GPIB) and it is shown on the MAX (a GPIB instrument as well as an IVI hardware asset)
I've tried GPIB connection but it gives me asynchronous signals...
Is it possible to get 2 signals at the same time with LabVIEW 7.0(not 7.1 or higher) by any means?
What in the earth is the "Config Server" in this case?
I don't need to sticking to IVI and any method to achieve my goal will be welcome.
Could anyone give me the hint for this problem, plz?

I think your problem is that the instrument specific driver is version 7.1 and you are using the class driver with 7.0. You can create your own 7.0 driver by downloading the LabWindows driver and using the Import CVI Instrument Driver under the Tools>Instrumentation menu.
Since you don't seem to have a good reason to use IVI, why don't you try the native LabVIEW driver at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9139659CE034080020E748.... I believe you have all of the functions to setup each channel and then when you trigger the scope, both channels will be captured. You would then transfer each waveform separately. The data is always read sequentially but that's not important as long as both channels are triggered at the same time.

Can I use Airport Express to extend signal from my Airport Extreme and then run Ethernet from Express to my TV which requires ethernet to access internet?

As stated in title. I want to access Netflix but my TV requires ethernet connection. I would like to use Express to repeat Exreme sigal and then to TV via Ethernet. I only have one access point in house for cable modem so I'm using Extreme to broadcast though house. Will need to be able to input network key for Extreme secure network. Thank you.
Mike

Are both your AirPort Extreme and AirPort Express 802.11"n" devices?
If yes, you can configure the Express to "extend a wireless network" and it will provide more wireless coverage and the Etherent port will be enabled so that you can connect an Ethernet device.
This assumes that the Express is located where it can receive a strong signal from the AirPort Extreme.
