No more sound to USB midi device Alesis iMultimix8USB

Hello
After playing hours and days without any problems it's no longer possible to communicate with my Alesis midi device iMultimix8USB.
I did all the latest updates. I did on my macbook pro too and it the device is working there fine. So the device is ok and the problem must be with my macbook.
So before the problem I plugged out the USB-cable and the sound switched without any problems to the internal speakers. After plugging in the UBS-cable back the sound stayed on the internal speakers. I have no idea what is wrong now.
In the system profiler it shows under USB the "USB Audio CODEC" entry from my midi device. So that should be OK. But in the system settings "Sound" I cannot find the old entries for the device under "Output". Only the integrated speakers are listed.
So what is missing? Thanks for any advice.

Oh, I remembered some problems while starting with iMultimix8USB some years ago. There I had to install a "special" driver to make it running (http://discussions.apple.com/thread.jspa?threadID=1797831&tstart=0).
Now I followed the instructions to deinstall the Yahama-USB-Driver and now it works again!
I think, the involved kernel rebuilt has somehow brought back the official Apple driver which is working now with the iMultimix8USB. This was not the case some years ago. But anyway it works now.

Generic "usb midi device" in 10.9 / Mavericks

What does Mavericks need to use the product string from the USB descriptor as the name of the MIDI port? I have an assortment of USB Audio Class 2.0 compliant audio + MIDI interfaces. Some behave as they do in Mountain Lion and earlier: If manufacturer Foo makes a product Bar with audio and MIDI interfaces, then the Audio Midi Setup windows will show an audio interface named Bar, and a MIDI port named Bar. If you double-click on the MIDI port, it shows the Model, "Bar," and additional information, including the manufacturer Foo, as retrieved from the USB descriptor. This is expected and desired, especially with devices that unlock features in non-free software.
However, with Mavericks, some devices (staying with the Foo/Bar example), though the audio interface gets named Bar, show up in the MIDI Studio window of AMS as "USB MIDI Device," and double-clicking reveals the manufacturer and model to be "Generic" and "USB MIDI Device," respectively. If you use the drop down menu at the top of this window to switch to a different configuration, or define a new one, while the device is connected, it appears in the second configuration as Bar, with the correct manufacturer.
Now, according to https://developer.apple.com/library/mac/technotes/tn2274/_index.html, the Interface Association Descriptor needs to group all the audio descriptors together, they need to be contiguous, and they need to be ordered by Audio Control, then Audio Streaming, then MIDI streaming. The device that isn't coming up correctly meets those criteria, so I wonder what else is missing.
Here's a dump:

Hi,
I have same issue with my device, but what's strange is that it's correctly detected under Yosemite but not under 10.9.4,
It's always detected as Generic Midi device under 10.9.4
Do you find the reason ?
Thx

Usb midi devices do not appear on os10.4.10

i've seen some similar complaints about firewire audio devices, and usb harddrive on this forum;
i've got a a few usb midi devices (m-audio oxygen8 and edirol ua-25) that do not show up anywhere on my computer (black macbook, os 10.4.10); i've checked the audio midi setup area, and all of the various software preference areas (garageband, absynth, reaktor, etc).
the workarounds for the firewire audio don't look like the right thing to do. i've installed the v1.1 audio update. with no change in problem.
the edirol usb device is an audio and midi device; the audio works fine (before i did the 1.1 update, crossing fingers that it still works) but the midi does not appear to exist on my system.
i've updated the drivers from the respective hardware vendors, no luck. looked for similar issues in all the knowledgebases i could find. every answer tells me to do what i did the first time. so i do it again and it still doesn;t work.
has anyone else had this issue? or has anyone else had a positive experience with usb midi devices?
i've recently switched from pc to mac,
so i've some out of depth feeling on the details of mac fer sure.
thanks,
dylan

Oh my god. All I had to do was reboot. Marking as closed.

USB midi device not showin up/installing

hello.
thanks in advance for anyone that can help me out here.
after many late nights trying to install the nana pad2 on my imac and failing...i've run out of ideas.
imac 27" OSX 10.7.5
2.8 core i5
12G ram.
i have the latest drivers (got them last night...again)
installed and re installed and manually deleted them and tried reinstalling several times.
no matter what i do the korg will not show up in
'UTILITIES' > Audio MIDI setup. nothing shows up in there other then my presonus audio interface.
i go into studio one and with the nano plugged in (via new usb cable) i can get midi "info" data to show up in the
'MIDI monitor' when hitting the pads...but no instruments are able to be triggered by the pad.
i've followed the install instruction for adding devices in studio one. but the main issue here is its not showing up at all in my imac "utilities".
i see some on the forums have got it working...but dont actually show or say how.
anyone out there conquered this??
thanks.

USB MIDI devices not detected under OS 10.5.2

Leopard's Audio Midi Configuration doesn't detect my Korg microKontrol, Novation Remote Zero SL and my Evolution MK-249C2 MIDI keyboard. Firewire MIDI device is detected (RME fireface 800).
Using the "latest" drivers - Novation Automap Universal 2.0.1178 driver, microKontrol 1.0.7 driver, Evolution keyboard doesn't need a driver.

Garageband recognize USB MIDI device - Still will not play.

I am using the newest version of Garageband with Yamaha YPG 525 keyboard connected via USB as a MIDI controller. Drivers installed successfully. This is not my first Yamaha keyboard used with Garageband. This issue I'm having is that under System Preferences it shows the MIDI device connected but will not allow me to select as the "input" device. It shows up in the "Audio MIDI Setup" app, and I've selected the "Send All Notes On" under the Yamaha driver application listed in System preferences. It's getting very frustrating because clearly GB sees it's there but just refuses to make playing it an option. I have searched dozens of forums but cannot find someone having the same issue. Please help!

USB MIDI device issues

My CLP-970A yamaha clavinova is not being picked up by garageband eventhough the UX16 USB device is recognized in the Audio MIDI setup window. I added the clavinova as a device and it tested "good".
I have a G5 iMac and run 10.3.9 the device manual says the UX16 supports OS X 10.1.2 through 10.2.6 so I looked on the Yamaha site. They have an update listed for OS X but there is no other information, no date created, or what the patch is intended to do etc.
Is this just a bad set up?
Does someone have a much easier and better solution to recording clavinova music in garageband? Suggestions, comments, please...Thanks!

I have tried software track and real instrument track.
A "Real" track will absolutely not work, MIDI is a software instrument.
You also didn't answer the first question I asked, does GB tell you a MIDI device is conected?
Is there a better interface
I can't speak for "better" but here are a few exmples of interfaces:

Can't get sound from USB input device

I've got an Alesis iMultiMix 8 USB mixer plugged into my shiny new MacBook Pro (running Leopard). The Mac properly recognizes the USB Audio Codec as a sound input device, and in fact shows a signal being received from the mixer. However, I don't actually hear any sound from the mixer, even with it selected as my input device, and my recording program still records only from the built-in microphone. What am I doing wrong? Thanks for your help!

Heh... it turns out that there was nothing wrong, at least technically. I got on the phone with Apple and asked if the native OS environment relays inputted audio through the speakers, and was told quite simply, "No." It looks like my PC schools Mac on that account.
As it happens, yes, the programs I was trying to use (Cubase, and I tried Garageband for gits and shiggles) DO have a monitor function to allow the ability, as well as ways to select your input. Cubase, the one I'd been experimenting with, simply has it coached in different (and extremely technical) terms and methods.
So, it looks like my difficulties arose from my lack of experience in a high-level audio program with a steep learning curve, coupled with what I perceive as a basic design shortcoming of Mac. (I think there should at least be an option in the OS environment somewhere.)
Ah well, live and learn. Thank you so much for your assistance.

Using more than one USB input device with Logic

I have 2 USB mic's that I would like to record to separate tracks in Logic Express. The research I've done seems to indicate that this is not possible because an audio interface is required for more than one input device of any kind. Is there any way around buying a $150 audio interface? If so, I'll complicate things further, the mics are SAMSON CU10's and logic does not recognize them unless you set them up with the Aggregate device editor. Another configuration I would like to use in a Line6 USB guitar interface on one track and a Samson USB mic on another. Any options or do I need to buy an audio interface?

The line 6 is an interface. Try setting up the mic & the Line 6 as an aggregate device-I'm not sure if you can couple two ag's together or not. Barring that, Lexicon's Alpha has dropped to $80.oo, I'm getting set to but one today.

UDev rules not working for MidiSport 2x2 usb midi device

I installed arch a couple of months ago and am loving it so far. Any problems I've had so far have already been solved in the forums, but this one's really got me. I have a MidiSport 2x2 that I want the firmware to be loaded on everytime I plug it in. I installed (there's not an arch package) a package that is supposed to do just that. (It's called midisport-firmware-1.2.tar.gz). However, the package seems to be out of date (2006) and I even had to modify a couple places in the configure script to get it to work with current program revisions. However, once installed, it does nothing. It installed firmware files and udev rules for the device into a couple of directories. When I run the command that is supposed to load the firmware, it works fine. But for some reason, (I even checked the udev kernel log) it's like the event isn't even being triggered. Here's part of the original file that came with the package that's supposed to load the firmware:
# midisport-firmware.rules - udev rules for loading firmware into MidiSport devices
# DEVPATH=="/*.0" selects interface 0 only
# (some udev versions don't work with SYSFS{bInterfaceNumber})
# MidiSport 2x2
ACTION=="add", SUBSYSTEM=="usb", DEVPATH=="/*.0", ENV{PRODUCT}=="763/1001/*", RUN+="/sbin/fxload -s /usr/local/share/usb/maudio/MidiSportLoader.ihx -I /usr/local/share/usb/maudio/MidiSport2x2.ihx"
# vim: ft=conf
And here's what I modified it to in an attempt to make it work:
# MidiSport 2x2
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0763", ATTR{idProduct}=="1001", RUN+="/sbin/fxload -D /dev/%k -s /usr/local/share/usb/maudio/MidiSportLoader.ihx -I /usr/local/share/usb/maudio/MidiSport2x2.ihx"
I would really appreciate help from anyone who knows about this kind of thing, as I can't figure out what's going wrong. If it's something wrong with the config, please let me know. Actually, some HAL events popped up when I was testing this out. Is it possible HAL is blocking the udev event somehow?

Hi,
The firmware files must be put in /lib/firmware so they can be found by the kernel. Are they being put there?

Good USB-MIDI interface

I can see other posts on this topic but they're from 2007
Can anyone recommend a good USB-MIDI interface… I have an old yamaha electric keyboard (about 15 years old) it has the midi in/out plugs so I assume it will connect okay to the Mac/garageband. I notice on ebay there are similar looking interface devices selling from around USD$6.00 to $40.00 (often it's better to spend more but not always)
That's one question, the other is: will it be likely that I will have to buy a more modern keyboard to work okay with garageband? I should mention that I have zero experience just now with garageband if anyone knows common problems with trying to wire up a keyboard to a mac…
Many thanks
Mark

Thank you Keith, and Hangtime… Once again you will have to forgive my total ignorance about GB to date… once I connect the keyboard I will be able to start playing around…
Keith could you clarify the bit about "do you want midi only, or audio inputs too"…? What form would 'audio inputs' take?
My keyboard has it's own selection of sounds, GB also has it's own collection of sounds. the USB-MIDI interfaces I have seen on bay are mostly just a cable with the 2 midi plugs one end, a usb plug on the other end and a small box in-between. What would "audio inputs" imply. would you normally record a GB audio file with sounds from the keyboard or those of GB. does "audio inputs" imply a 3rd selection of sounds?

Can't connect MIDI devices in Audio Midi Setup

In the help for Audio Midi Setup, step 7 says you can connect devices as follows:
"7. To specify the connection between MIDI devices, drag the output or input connectors above the device icon to the corresponding connector on the other device icon."
I can drag out a line from the device ports ("connectors"), but cannot find a way to make those lines "stick" to a second MIDI device or its ports -- i.e., I cannot connect devices like this at all.
Is this just me? Is this feature not yet implemented perhaps?
Thanks!

Ok, I finally solved this. For whatever reason, I could not set up connections between my auto-detected USB MIDI devices in Audio MIDI Setup -- maybe it is just not designed for this, or maybe I'm still not understanding what to do. i.e., I could not connect my E-MU 0404/USB to any port on my MOTU MIDI Express 128.
However, I was able to configure the individual MIDI interfaces (i.e. the E-MU or the MOTU, separately), using "Add Device" and then connecting between those interface devices and the newly added devices. This was the first time I had seen the "connectors" actually "take" and connect between entities within the Audio MIDI Setup utility, so that was a relief. Presumably doing this informs applications on the Mac how the MIDI system is set up -- I just thought it did more than that, i.e. allow direct routing between MIDI devices using just the utility itself.
I still don't know if I am meant to be able to connect a keyboard to a synth using just Audio MIDI Setup alone (what I had hoped), but I certainly can't seem to get that simple config to work and will have to resort to using some additional software like a sequencer. Not my preference, but c'est la vie.
Thanks for all the suggestions,
Stewart.

External MIDI device, can't get more than one sound, Logic Express 9 & Korg N364

Hi, I just beginning to use Logic. I trying to get Logic Express 9 to work with and use my Korg N364 keyboard/workstation as an external MIDI device. I can only get one sound at a time even though I create multiple tracks and assign different programs (or patches) to them.
Each time I do the following: I add a new external MIDI track, change the Channel to new number, put a check in the Program box ( as well as the Volume & Pan), and choose a instrument or patch from the Program drop down menu. What happens, though, it changes the sound to that instrument alright, but ALL THE PREVIOUS EXTERNAL MIDI TRACKS HAVE THE SAME SOUND NOW. I've followed the tutorials I found on the web and it seems like I'm doing everything correct in Logic. I hooked up the MIDI cables, added a new device and connected virtual cables in the MIDI studio window of my Mac OS, and have added the proper Korg multi instrument in the environment window of Logic and "un-slashed" the 16 channels. I get the sounds from the Korg no problem, it's just that I can only assign one sound and no more to the external MIDI tracks. Is there something in my Korg I need to do? Or am I missing something in Logic?

It's not Logic, it's how you have the Korg setup.
I'm not familiar with that model but it is a workstation so I'm pretty sure you can set it to a "Multi" mode.
Right now you are running it in single patch mode.
In single patch mode only one sound is available on a single MIDI channel, your Korg probably has a Multi or Combi mode, this is where multiple sounds can be played, each sound has to have it's own MIDI channel.
You will need to set this up on the Korg first.

USB MIDI class-device oddities with more than 16 ports

Hi,
just playing around with programming an USB device stack for the AT91SAM7 MCUs. Because i do a lot in music electronics, i tried to implement a MIDI device (Audio/MIDISTREAMING) according to the specs:
http://www.usb.org/developers/devclass_docs/midi10.pdf
And, just for fun, i wanted to try if it works if i use 2 output endpoints to get (theoretically) 32 physical MIDI OUT connectors. According to the specs, this should be possible (page 9):
"The USB-MIDI Converter typically contains one or more MIDI IN and/or MIDI OUT endpoints."
"Each MIDI Endpoint in a USB-MIDI converter can be connected to up to 16 Embedded MIDI Jacks."
So. I can use "more" IN and/or OUT endpoints. I did so. I have 1 IN endpoint, 2 OUT endpoints. And on each endpoint, i have 16 embedded jacks connected to the external jacks (which in fact are currently just simulated
Now what is the reason why i write this?
On reception of data, everything works fine so far, but i didn't check with more than 1 endpoint so far. On transmission, i can address the first 16 jacks on the first endpoint without any problems, but the other 16 jacks (which are on the second endpoint) are routed to the first endpoint by OSX.
I can see this in the display i have on the MCU, and i also can see that everything goes to the other endpoint if i just exchange the endpoint numbers in the configuration descriptors. So i think my code on the MCU does the right things, but OSX doesn't seem to be able to handle more than one output endpoint.
This also might apply to the input endpoints, i don't know.
Did anyone observe similar problems? I don't talk about such things like those Emagic interfaces, they are not implemented according to the standard class device specs, they have some more features and need a proprietary implementation.
Not that this would be too important, but i think it might be a bug worth fixing.
...Michael

Either i'm asking in the wrong forum or you are posting on the wrong threads
I will virtualize the situation for you, the rest please stay with the initial post, as meanwhile, all the important details are lost.
Yes, this is a box with 32 MIDI-Out connectors and 16 MIDI-In connectors besides the USB connector. I can see this interface with exactly this configuration in Audio-MIDI-Setup (now this is real, not virtual , and if i configure any software to output on Port 1-16 (not channel!), the signal appears on Port 1-16, but when i configure Port 25, it appears on Port 9. So Instead of Ports 17-32, OSX sends the data to Ports 1-16 again.
