Setup with USB

I am having problems with my line in AND line out of my 1 year old MacBook Pro. I have an appointment to get it looked at Saturday. I've read where others have had to replace the Logic board and it was quite expensive. While my MBP should still be under warranty, in the event I have to pay something, can I get an Apogee JAM that will connect my guitar to a USB port and external speakers that also connect to a USB port to offset the issues with the 2 ports? Everything work fine on my MBP with the exception of those two ports. Do I benefit from using USB ports rather than the audio jacks? An increase in quality of sounds or tracking? My main goal is to create music with garageband.
Thanks for any suggestions.

It would be only for my entertainment. Something I can create for others to enjoy. Input wise, I'm looking at electric guitar, acoustic guitar, keyboards, vocals. Just your basic recording inputs. As for cost, I'm won't go the cheap route. I'd rather spend a few more dollars and get the most bang for my buck but for the same token, I don't need "over the top" pro quality stuff either. Hope this helps.

Setup with USB keyboard and microphone

I am a novice to Mainstage 3 but I would like to use it to some sound experiments, but I would like to be able to set it up so that I can have input from mye USB keyboard (M-Audio Keystudio) and a microphone (either CADu37 USB-mike or Behringer C-1 XLR). It seems like I need to get an audio interface to be able to do that, but it also seems like most only have the normal MIDI In and Out and not USB. If they have USB they are only USB-powered but no USB-connection in.
I also tried to add aggregate device in the Audio MIDI Setup but didn't get it to work. Maybe it isn't for that, either? Perhaps the keyboard should be connected directly to the computer and not through a USB-hub as it is now?
Anyone has a good tip or advice?

If you cant connect a ps2 keyboard you should RMA that board and fix that port. USB keyboards wont work if USB drivers are not loaded . There may be a work around but none that im aware of.

IRQ problems?, especially with USB.... read this

Summary: the following things are listed to help people configure or disable USB and USB IRQ related options, some steps may help diagnose/eliminate other IRQ problems. Some Operating Systems/Motherboards may have Similiar or Alternative ways to preform the following options,(Some may not be compatible with these Options):
From initial installation problems to suddenly not working USB, cleaning up the Device manager in Safe mode is the first step. Many hardware related problems in Windows can be traced to ghost devices and duplicate device entries. Obsolete and/or duplicate devices can ONLY be seen and removed in Windows Safe Mode. This procedure MUST be performed in SAFE MODE.
USB can only share its IRQ with other USB Host controllers (such as a USB upgrade card, if applicable) and IRQ Holder for PCI Steering. (Some of the newer motherboards can share USB Devices with their On-Board Devices,ex: K7N2 Delta
In most cases for mother boards the First and Last PCI slot share the same IRQ as the AGP slot. This is not always the case, and is usually addressed in the motherboard's manual. In some motherboards there are other slots that share IRQ's with other on board devices, these can lead to conflicts and errors later; try changing cards in PCI slots around.
Sometimes you may find that when you have installed a new card (or device) into the system, other devices such as the sound card may stop working. Once again, the resource configuration needs to be changed. Do so by going to Control Panel, System, Hardware, Device Manager, (Com1) ,or other port's properties, disable usage. This is also the best way of disabling hardware so that if necessary the customer can turn the hardware back on through windows rather than having to play in the BIOS.After disabling a device in the BIOS boot to Safe Mode and delete the device from the Windows Device Manager. If the device is not removed from the Windows Device Manager in Safe Mode, Windows will continue to recognize the device and Windows will continue to assign it an IRQ.
In some versions of the Award, AMI and Phenix bios you can select Plug and Play OS installed. This option lets you decide whether windows should handle the IRQ routing of devices or if the BIOS should handle the routing. Please note that if this option is enabled windows will show a completely different setup of IRQ's then what the BIOS reports You may wish to toggle this option if you find that moving the card dosn't work. This in some cases will change the way windows will assign IRQ's. In most cases this will help but not in all.
Another section that you might want to look at is if the IRQ's are being assigned manually or automatically. Sometimes it is better to manually assign IRQ's and other times it is better to automatically assign them.You can do so by entering your BIOS... should be listed under PNP/OS or PNP/PCI Configuration. ( You must disable Plug N Play feature for this to work!)
Properly installed IRQ Steering is critical to correctly working USB. If IRQ Steering is disabled the likely cause is improper BIOS settings. See the section on BIOS Settings. Go to Control Panel, System, Hardware, Device Manager, System Devices, PCI Bus...If you do not have the following options, then obviously your system shouldn't be configured this way. Seek alternative means to enable/disable them. View Status, go to Settings tab, Use Hardware should be enabled, go to IRQ Steering tab... The following options should be checked... Use IRQ Steering, Get IRQ table using ACPI BIOS, GET IRQ table using MS Specification table, Get IRQ table from Real Mode PCIBIOS 2.1 call.... Under IRQ Routing Status the following should be displayed: (AMD) system should read: IRQ Steering Enabled, IRQ Table read from ACPI BIOS. (Intel) system should read: IRQ Table read from MS IRQ Routing Specification), IRQ Miniport Data processed successfully, IRQ Miniport loaded successfully. If IRQ Steering is not enabled. Reboot the system to the BIOS setup (Usually holding the DEL key at bootup) and Enable (Plug and Play Operating System). Set (Assign IRQs) AUTO or System. IRQ Steering is essential to proper USB connectivity. BIOS control of Power Management should be Disabled or set to User...
If all the above doesn't work, you can look at the hardware in the computer and disable any that is not nessasary. This will free up some IRQs and on the next reboot the IRQs may be reshuffled to a better configuration. Common hardware that is good to disable are com ports and USB controllers. If you are not using your serial port for anything, disable COM1. If you are not using your USB try disabling the USB controllers and hubs. If you are using a USB mouse, try pulling it into the PS/2 port if possible. All these things will free up and change the available IRQ's, and allow USB devices to automatically select them.
Disable USB Error Detection In Windows Standard Mode, Device Manager, USB Host Controllers, (SiS, Standard, ect..)USB Open Host Controller, Advanced, Enable the function (Disable USB Error Detection).
With some motherboards you may need to install the newest version of the motherboard drivers and also may need to flash the BIOS.An example of this is VIA motherboards. The VIA or Apollo chipset boards require an update for their IRQ routing with windows. This update helps fix problems such as loss of data and such.
If you still cannot isolate USB to it’s own IRQ, changing the I/O range of USB sometimes works.
Possibly your last resort upgrading to USB by PCI/USB upgrade card is a recommended solution for systems with non-functioning onboard USB host controllers. Properly Installed the USB upgrade host controller should share the same IRQ as the onboard USB host controller. Check the motherboard manual or Manufacturers Web Site and install the new card into a PCI Slot that shares it's IRQ with USB. Do NOT disable USB in the BIOS as the upgrade card may not work if you do.
If that won't fix it, you may want to contact your mother board's manufacturer, or retailer who sold you the unoperable System components, to see if your System is under any kind of waranty/recall; then order a new motherboard and components...there is always the possibility you will end up with same problem. Or you can contact a computer tech in your area. Goodluck...
Misc Tips....
Check all Physical Connections (This includes: Motherboard mounting, cables, plugs, and visibly damaged components)...
Don't use cables longer than what you need, this can decreases efficiency and or causes System instability...
Check your Voltages in BIOS, and on your PSU (power supply unit); make sure your system is not underpowered...
Check your CPU/System Temperature, check airflow/fans, then check with your CPU manufacturer for acceptable settings...
Check BIOS, Drivers, Firmware, and Software for latest settings/updates...
Check Compatability (can find information in your Motherboard, BIOS, and Device Manuals...
Don't Overclock or Tweak settings you don't understand, unless you like the smell of toast...
And finally, don't me scared to ask... no one here will think less of you for seeking info/help from those who know...

Also if this has helped you or someone else in anyway please reply.

IPod Touch works with USB 1.0, why not iPad

I just received an iPad as a gift but I have an old 17" iMac with USB 1.0 and it's not syncing with iTunes to setup. My iPod Touch syncs perfectly with 1.0, so why not the iPad? If it won't work, i guess I'll return the iPad and get credit towards a new iMac.

Read the system requirements for the iPad to see if your machines have the correct OS and iTunes version.

Incompatability Issues MAC OS 10.4.10 With USB headphones

I bought iListen so I could type more quickly as I have some disability issues and type very slowly. I had a lot of trouble training iListen. I bought a package which included a Platronics USB headset and USB Mic fromthe Apple online store. After many issues I was able to find out from Plantronics that MAC OS 10.4.10 has some compatability issues with USB Microphones. After making sure the System Preferences are correctly chosen in Sound and Speech Panes you can follow the steps below, I hope this helps some others to avoid this frustration.
The following applies only to Macintosh computers running Mac OS X 10.4.10.
If you experience no transmit (i.e. the mic doesn't seem to work), please try the following:
1) Make sure your Plantronics microphone is plugged into an open USB port on your computer.
2) Launch "Audio MIDI Setup.app." (You will find this application in Applications> Utilities.)
3). In System Settings, select "Plantronics Headset" as the default input.
4). In "Properties For:" select "Plantronics Headset."
5). In the bottom right area of the window, uncheck "Mute."

I have had communication from MacSpeech which indicated they actually gave the solution to Plantronics and were aware of the issues. I did not realize that there was an issue that was not with me because it only happened some of the time that my computer muted the microphone and resorted to the built in mic! Hope this helps someone else

HT4356 I have an HP 4500 printer connected to airport extreme with usb. All our portable notebooks print via air but cannot get iPad to be recognized for printing. Do I really have to have one of the other HPs listed?

I have an HP 4500 printer connected to airport extreme with usb. All our portable notebooks print via air but cannot get iPad to be recognized for printing. Do I really have to have one of the other HPs listed?

Rufus Cat-
Even if it was compatible, AirPrint does not work through a USB link, only Ethernet or WiFi.
I do not see your HP 4500 listed on Apple's list of AirPrint compatible printers. <iOS: AirPrint 101> Therefore you need to take another approach. To start, I suggest you download the free HP App, ePrint Home & Biz. It has limitations, but should get you printing with your existing setup.
There are other printing Apps with more features such as Print n Share and PrintCentral, but they can only be accessed from within other Apps that have the "Open In" option.
Your best option may be to share your computer's printer as AirPrint over WiFi. Programs that are reported to do that well are Printopia and FingerPrint. Your computer must be on and awake any time you want to print. <Printopia for Macintosh> <FingerPrint for PC and Mac>

Mini Dock Series 3 with USB 3.0 vs. ... with USB 3.0 - 90 W vs. ... with USB 3.0 (170W)

I am running a
Lenovo T530, Quad-Core
Intel i5-3320M CPU @ 2.6 GHz
8 GB RAM
Windows 8, 64-bit
I am using a 90W 20V power adaptor.
I want to see the difference between mainly the Mini Dock Series 3 with USB 3.0 Dock and the Mini Dock Series 3 with USB 3.0 Dock - 90 W. From looking over the descriptions, they seem to be the same product, yet the latter is $20 more expensive. Could someone explain why that is or if a difference exists?
Will my specs allow me to have a quad display configuration?
From looking at other posts, I assume using a 170W power adaptor on a laptop that runs with a 90W power adaptor is a bad idea?
Thanks in advance!

Your Intel i5 is a dual core CPU, not a quad core CPU (in case you didn't already know).
The difference between the docks you listed, one is with 2 x DP + 2 DVI while the other is 1 x DP + 1 x DVI.
Does your T530 have Nvidia GPU? If you do, then get the dock with 2 x DP + 2 x DVI (Series 3 Plus dock), this will give you quad displays setup. The one with Intel GPU will give you triple display setup through the dock.

Newbie with a Motif ES8 - optimum setup with a minimalistic approach?

hi,
I'm trying to decide on the optimum setup with a minimalistic approach!
I a newbie with the Motif ES8 and am at cross roads deciding on the type of computer setup for my VST.
PC + Cubase vs. MAC + Logic Pro or Logic Pro Express?
With MAC, how far do I need to go;i.e. MACBook Pro a must?
how many USB ports (types 400 vs 800), etc?
With Logic Pro, is Express going to be sufficient for a full soup to nuts recording and mastering given that this is for a home studio setup though with an idealist running it?
I'm a one woman show and so don't need too many inputs/outputs. I'd be recording a track at a time and my songs take up less than 16 tracks.
I would really appreciate any and all responses.

macbook pro Mac OS X (10.4.7)

thanks for the detailed response PK
so, the extra USB port on the HD would facilitate a
hub type interface i.e. once you hook up another\
device to the HD via USB, you're really hooked up to
the computer.. right? and so, if I get a powered USB
Hub, this wouldn't really matter.. correct?
For the most part, you have to be careful hooking
too many devices up to a computer WHEN you are trying
to do some sound work. When they say a computer
can do ABC we sometimes think that should include D.
As for the sound interface, I already have an
Audiophile that has midi in/out, firewire to
computer, RCA jack for i/o. I know its not the high
end stuff but I hope to do a stepwise upgrade here if
at all possible..
That actually might work, if it supports at least
16 bit 44.1 khz that is the lowest you want to go.
Ideally it should be 24 bit to take advantage of Logics
24bit environment. You might be able to run the ES8
straight into those RCA jacks if they are SPDIF and your
keyboard has the same on the back.
There are a bunch of people on Motifator discussion
groups that warn against Apple's lack of support for
Logic. Not sure if the concern is only regarding the
combination of Yamaha (Motif) and Apple (Logic).
I went and read that thread, here are some of my thoughts
on some of this.
Can't comment on MAC, but a dear friend of mine who is an audio engineer said >he had walked away from Logic after Apple bought them out. "Straight downhill" >I think is how he put it.
Many windows users just hate Apple and their products.
I think much of it is ignorance. They will say
Macs are junk but when I ask them why
they never have an answer or say something
that is false. It sounds like this "professional"
did not even wait to see that Logic did get better.
Apple charges 200.00 for support of it's Professional
applications. You really do not need it since there are
so many experienced Logic users here that I never had
a question go unanswered. I've noticed on those forums
the same small group of people do most of the problem
solving. I am not overly impressed with Yamaha's support.
I had my questions about my keyboard answered quicker
by those forums. So I guess both companies need work
in this area. Frankly, for recording, I think the Motif
and Logic are a Killer combination. Both have steep
learning curves but once you get up to speed I think
the results speak for themselves. The main difference
in my opinion is that the Motif is the ultimate
performance tool and Logic is the ultimate studio toolshop.
After having a Motif for over a month, I am convinced
it has a steeper learning curve than Logic take for instance
that thread on getting your keyboard to record it's own
audio output. The list of things to do each time is as long
as my arm. In case you did not read it here it is.
First thing – STORE your MIX setup and SAVE the Song to SmartMedia (or USB mass storage device) before resampling it so you have a backup. You would create a mix to balance the instruments the way you like them.
* Select a target track, then press the [INTEGRATED SAMPLING] button.
Setup the parameters for resampling:
* Press [F1] DEST
* Select a TRACK and [KEYBANK] (note) into which you will record the resampled data. You can target either an empty track or the track on which you are going to play (if you are going to play along). If all tracks are full, don't worry, you can still resample anyway.
* Press [F2] SOURCE. Set the source parameters as follows:
- Type = Sample - with this type the Integrated Sampling Sequencer will not create any NOTE-ON data in your sequencer, it will just simply add a new sample waveform to the waveform list
- Source = Resample
- Mono/Stereo = Stereo
- Next = OFF
- Frequency = 44.1k
* Press [F6] REC This will place the sampling sequencer in Standby mode. Set the TrggrMode paramter to Manual
* Press Start on the sequencer and check your levels. If too low set the REC GAIN higher +6bB or +12dB, if the level is to high (clipping- you will see a lightning bolt) lower the GAIN to -6dB or -12dB. When you have checked the levels, press STOP and return to the top of the SONG.
* Press F6 REC to start the Resample, Press [>] (play) to begin recording the resample. The Motif ES will draw the wave as it samples.
* When the song is over press [F6] STOP. The Motif ES will take a few moments to gather the data.
To create the .wav file:
* Press [FILE]
* Press [F1] CONFIG
* Press [SF1] CURRENT
* If you will be saving the resampled song to a SmartMedia Card set the Current parameter to CARD. To save to a USB device, set this parameter to USB
* Press [F2] SAVE
* Set the data TYPE field to WAV
* Cursor down and Name the wave
* (If desired, navigate to the subdirectory where you want to save the *.wav file.)
* Press [ENTER]
* The ES will ask you which TRACK and NOTE to save as a wave file. Enter the values you selected as the sample destination in the procedure above.
* Press and hold the AUDITION button to make sure your sample is there.
* Press [ENTER] and the Motif ES will export the sample as a .wav to your SmartMedia card or USB device.
Once you have configured Logic which are takes about
3 minutes (and only has to be done once)
and set up the keyboard which takes 30 seconds.
(this has to be done once for each session)
you plug your keyboard into your audio interface then
Hit Record
that is the whole list, two words.
Once it is in Logic, you have many way to edit it
and process if needed. The midi is much
easier to manipulate and there are more
ways than the ES has keys. Plus you can add to the
sounds with the internal instruments which are
as sophisticated and as high quality as the ES.
Then if your happy with it you can create MP3's
and burn Red book compliant CD's for
commercial duplication.
It really is a complete setup.
But at any rate I'm going to do some more research on
another scenario, i.e. what about MAC and Cubase? As
you may know Yamaha just acquired Cubase..
I dont think I would be the best to comment on that.
Maybe ask one of the Gurus on the unofficial
website for Cubase, The Cubinator.
Sorry, I just couldn't resist.
you've been very helpful - thanks again
cheers,

Permissions / Sharing - Problem with USB Drives

Hi,
I suspect it's possible to do what I want, but not via the "easy" route. I'm very new to OS X, so hoping there's some more advanced functionality I haven't found yet.
This is what I want to do:
I have a USB drive connected to a Mac Mini running Snow Leopard. I have two users setup - one admin, one normal. I want only the local admin account to be able to access the files on the USB drive. I want the admin account to share the contents via the local network with my (Vista) laptop (which is setup with the same username / password as the admin account).
Problem I have is that whenever I try to apply any permissions to the USB drive, they are ignored. From what I've found on the internet, that is "by design" behaviour.
Are there any ways around this that people can suggest? Scripts? Other utilities? Other settings hidden away somewhere?
Beyond that, ideally I'd like to encrypt the whole drive as a TrueCrypt partition, mount the drive automatically when the laptop is detected (using a keyfile stored on the laptop), and then only let the laptop access the drive. But I'll accept a simple solution for now!
Thanks,
David

select the external drive in finder and enter command+i. in the resulting popup unlock the lock and uncheck the box to ignore ownership on this drive. permissions won't be ignored now. give your admin user read+write permissions to the drive and remove them from everybody else. that should do it.
I don't use TrueCrypt and can't comment on that.

Sun E3500 with USB Keyboard?

I've got a Sun E3500 server and have a Neuro-Logic RFT-17 Rackmount LCD Console that only has a USB connection. I know that this rackmount setup is MADE for Sun, as it is actually being sold by Sun. Are there converters to go from the Sun 8-pin layout to USB? Thanks!!

Hello,
you are using a Neuro-Logic RFT-17, which is "just" a LCD display and a keyboard that fits into a rack.
Please don't get me wrong, but did you even thought about contacting Neuro Logic Systems, Inc. ?
http://www.neuro-logic.com/1u.htm
According to their FAQ, two (keyboard) options for Sun are available: USB or 8-pin serial.
http://www.neuro-logic.com/1ufaq.htm#6
The User's manual isn't available for download (links returns to the same page !!!), but this is from the data sheet: "USB and Sun Serial connectors".
Using an add-in USB board (are there any for S-Bus ???) won't help to solve the issue. The OBP only supports "standard" Sun keyboards with Mini-DIN connector (this is what NLS calls 8-pin serial).
If the RFT-17 isn't equipped with USB and Mini-DIN keyboard you can take the KVM "route".
Despite the fact that a Sun server doesn't require a directly attached keyboard/monitor, these systems are managed thru network or (serial) console/management port (console server for multiple systems and capturing the console logs), you can extend your installation with an expensive (Sun certified) KVM that offers adapters for USB and Mini-DIN attached keyboards.

Synchronize Series 2 PCMCIA CAN/2 with USB-6229

Hi,
Just want to know if it's possible to synchronize series 2 PCMIA CAN/s or USB-8473s with USB-6229. If so how to connect the two setup together through RTSI connection? I assume I would follow the example VI "CAN Sync Start with NI-DAQmx". Thanks.
Jason

Hi Blayne,
Thanks for your reply. I used the reference design and connected it as follow. However I can see that the CAN and DAQ start is still not synchronize, I suspect I need to configure the startTrigger. Basically I want to it to start capturing analog and CAN data simultaneously when I start running. Analog signal will always be there, I suppose to set the trigger source to an analog input (AI0), when it start capturing, generate a pulse on the startTrigger to start CAN capture. How would I go about doing this?
From the USB-8473s to USB-6229
CLK -> 10Mhz pulse AO to PFI12
TRIG -> ai/StartTrigger to PFI0
GND -> DGND
I've attached a draft of my program.
Thanks a lot.

[SOLVED] How to achieve the best sound quality with USB DAC?

I want to take full advantage of my hardware. However, I'm having trouble understanding what settings I need to configure. I've spent several hours reading through wikis and searching online. Ultimately, I'm trying to achieve the highest quality audio output in stereo that's possible with my setup. USB > Behringer UAC202 > RCA out > Audioengine A2
I've had this DAC working for a couple of weeks, but I noticed that MPD was still eating a lot of CPU cycles upsampling music from 44.1 to 48khz. As I looked into it, it seems that this is unavoidable with ALSA, so I need to use OSS. Is that true? There's some conflicting ideas about when it's necessary to use OSS. I'm not using any legacy applications or old hardware. The "Hardware mixing" section in the ALSA wiki is pretty sparse.
I want all sound to go through the DAC, so I disabled all of the sound options in the BIOS (HDAudio and HDMI audio). I shouldn't need those enabled, right? (What's strange is that ALSA no longer wants to load without them.) I've added the OSS daemon and it starts, but I still don't have any sound in KDE. It no longer offers the "USB Audio CODEC" option. I'm ok with no system sound for now, if I can get MPD working.
/etc/mpd.conf contains:
audio_output {
type "oss"
name "UCA202"
device "/dev/oss/usb08bb2902-1/pcm0"
format "44100:16:2" # optional
mixer_device "/dev/mixer"
MPD is still starting as the root user. (I know, I should change that)
The daemon starts, but trying to play any track results in the following error in /var/log/mpd/mpd.log:
May 21 10:46 : output: "UCA202" [oss] failed to play: Write error on /dev/oss/usb08bb2902-1/pcm0: Input/output error
So... any help would be appreciated. Maybe, first of all, do I need to use OSS or should I switch back to alsa? Or maybe something else like jack?
*******EDIT*******
ALSA was the correct choice. The simple solution was to create /etc/asound.conf containing:
pcm.!default{
type rate
slave{
pcm "plughw:0,0"
rate 44100
Then change the audio output settings in mpd.conf to:
audio_output {
type "alsa"
name "MPD ALSA"
device "hw:0,0"
mixer_control "PCM"
With these settings the DAC receives 44.1khz audio and no upmixing occurs. Only one application can make audio output at a time. MPD uses much less CPU.

For good sound quality, flat response is the most important thing. Take a look at qloud, http://aur.archlinux.org/packages.php?ID=34412, and find yourself a very good microphone.
Then you will probably want to set a global equalizer for your machine. You can try with alsa, http://krustev.net/w/articles/Global_eq … _for_ALSA/.
If ALSA isn't finegrained enough, jack has a lot more flexibility, except for the fact that it doesn't allow you to set default output device, so you will need a helper application to redirect all output connections to your equalizer.
Well, i would say this is quite subjective. Untouched signal is superior to any equalized sound in my opinion, but i know this debate is never satisfying
