Yamaha Kx8 Driver

[Katina Piccirilli]

Researchingthis problem suggests that the USB driver has failed to install. Though all the articles talk about Mac OS X 10.11 or earlier, or specifically Macbook Pro Apple Silicon processors.

I have uninstalled and reinstalled it and the Tools package several times.

I have checked the Security & Privacy panel, but there is no notification asking for acceptance.

Restart/Power on your Mac (Apple > Restart / Shut Down).

Recovery Mode: Hold down Command-R until the Mac logo appears

Enter Password

Wait for OS X to boot into the OS X Utilities window.

Run this command in Terminal:

csrutil disable

Interestingly, now my UR22mkII is showing in the Audio Setup menu in the Audio Midi settings window, so I can use it or add it to an Agregate device.

I am left with the question, should I re-enable the System Integrity Protection?

Your solution helped me get bac the ALLOW button and I DID get the Kernel Cache Rebuilding message. Restarted after that and all yet the driver still does not show up correctly in AUDIO MIDI , just a blue generic usb icon named AG06 and no signal on either channel.

Problem appearently solved: I ended up with installing 1.10 disregarding the instructions to unstall the old driver first. That seems to have done the trick, except I do not dare to uninstall the driver now, just to check whether it can be done. But by next driver-update I will try to uninstall - otherwise install the new anyway.

has anyone ever used this software without a problem of it and it just working as paid for and expected or always issues? I am so thinking of settling on Logic X that works. just works. seems to me you need a cubase and yamaha team of experts on yourside just to get it working day one. I have asked for help but got sketchy help. starting to lose faith. I want to love this cubase software but I might need a computer science programmer degree just to fix what should be working day one.I really needed the product to work and function great. anyone else had a nice cubase mac experience? I have had nothing but broken software. I wish I could get cubase direct experts to help me I wanted to buy the 9.5 pro version but I am losing confidence fast.

The installer is looking for that file in order to uninstall the old driver. I had this problem and used this Microsoft utility to get rid of the old install. That a temp installer file must remain on a users computer over a period of years in...

That a temp installer file must remain on a users computer over a period of years in order for an update to work is the rudest, user-unfriendliest, out-dated, and ridiculous method around. So stupid. So annoying. So Windows 3.1

I just replaced one of my 10 year old yamaha's with the 485. this was a hard driver to find, but I managed to get one of the newer RX drivers working for IP control. I dont remember the exact driver I used, but it was one of the rx a drivers with a 2016 publish date from yamaha. to get it to work I had to identify it using the network tool for IP address, then also put the IP in the driver window in system design, then redo the connections and also a system reset.

I can select the ASIO driver (Yamaha USB driver 2.1.3), and it mostly works, but there is a persistent crackling sound. When I select this driver I get the message "This driver is known to be incompatible with Cakewalk," and it offers to switch to WASAPI. But in WASAPI mode, the crackling is *much* worse.

Is there a different ASIO driver I can use? How can I use this Yamaha audio interface with Cakewalk?

I'm use the Yamaha Steinberg FW Driver V1.6.6 with my Motif XF6 and have no problems with it... One thing you might want to check is MMCSS... If your USB driver 2.1.3 is like the driver I'm using MMCSS is select-able in the driver... If you have it enabled in Cakewalk and in the Yamaha USB Drive it can create problems, search this forum for MMCSS...

I've resolved the problem. A generic ASIO driver was selected in Cakewalk (I'm not sure how, since I had selected the Yamaha driver earlier), and when that driver is selected, the Yamaha driver is greyed out. But deselecting the generic driver allows the Yamaha driver to be selected, and with that change, the problem is gone.

This compression driver uses a unique suspension system. The surround is comprised of 15 tiny copper beryllium arms that flex to allow diaphragm movement. Between the arms are open space to allow air movement.

The driver uses a 1" to 1.4" conical adapter which can be removed. This is not technically how the driver was intended to be used, however using this 'modified' driver on a 1" throat horn allows for a more optimal flare geometry in the throat. I'm not a fan of conical adapters and I avoid using them if at all possible.

Below is the front of the horn for reference. I only tested the HF horn and used the bass cabinet below simply as a support stand. But at least my measurements would show the effect of the bass cabinet below (if any).

To reassemble the diaphragm back onto the driver I decided to run a 400Hz sine tone with my microphone placed near the diaphragm. I took it a step further and used the spectrum analyzer within ARTA to show me harmonic distortion + noise in real time as I tightened the screws. When I first remounted the diaphragm I was getting around 6% distortion. I then decided to rotated the diaphragm to the next set of holes. This reduced the distortion to 4%. I then rotated it again another set of holes and it reduced to 2%. Finally I removed all the screws and started securing the screws one by one while observing the spectrum analyzers real time distortion. I found that by adding only the four screws reduced distortion to 0.50%. If I added the other two screws (see my fingers in the picture below) then distortion would increase as soon as they started to snug down. I thought I would mention this procedure in case anybody suspects they have a voice coil rub issue. After I finished this procedure the driver sounded noticeable better. The 400Hz sine tone had a purity to it that it did not have when I first attempted to re-installed the diaphragm.

The frequency response shows excellent linearity with a -3dB down point of around 11kHz. There is a +3dB hum centered around 1.4kHz. This could be taken care of with a notch filter if it was found to be objectionable. The low frequency extension of 600Hz matches the Fc of the this horn (600Hz).

The Yamaha digs a little deeper into the low frequency however it doesn't have the same high frequency extension as the TAD. However one thing to note is that the Yamaha has a similarly smooth frequency response! This is quite an achievement! Considering the cost difference between the two, the Yamaha is a viable alternative. At the time of writing, this Yamaha is available on the used market for $650 USD per pair.

The impedance sweep shows a very low fundamental resonance of 300Hz! This is impressive! Note that I've removed the rear chamber for my testing. Above 300Hz the impedance remains extremely flat. For reference if any peaks show up in the impedance sweep this is always accompanied by resonances in the time domain. The high frequency breakup starts at 12kHz which also corresponds to the sharp drop in the frequency response. So the high frequency breakup (assuming that's what it is) is likely a high Q suck-out in the response and not a peak. I'd rather have a little less high frequency extension than a resonant mode peak that's clearly audible.

Using a multitone signal at 90dB at 1 meter produced the following noise spectrum. Side bands are -70dB down at 8kHz. This is only 0.030%, the lowest I've measured. Admittedly I've only tested a few drivers so far!

I've shown this data in other posts and I will share it here for convenience. The polar map shows that this can indeed be used in a high quality 2-way providing wide, evenly controlled coverage from Fc-20kHz.

This concludes my testing of the Yamaha JA66181B. Grab a pair on the used market before somebody else does! These drivers were sent to me by a customer for testing. The customer was merely interested in how they would perform. I plan on sending the drivers back to him. I don't think he will be letting them go!

For DOS I have always used creative cards in the past. Right now I am building a K6-2 system which can be slowed down to 386/486 speeds. I plan on using a Labway A151-A00 with Yamaha YMF719 chip along with a DreamBlaster S1 for sound. Oddly I've not been able to find a Windows 98 or DOS driver for the Labway card? Am I missing something?

So I just finished installing Windows 98 SE and it looks like there is a driver built in. It recognizes it as a "YAMAHA OPL3-SAx" so it appears I may have asked the Windows 98 part of this question prematurely, unless there is a better driver then the one that's built in. Now just need the details on getting it to work in DOS mode.

I could not find any drivers on Yamaha's website and google searches didn't find much. I did find one reference to a Labway driver CD on Vogon's Drivers which indicating it was for a YMF724 chip. I went ahead and downloaded that and it looks like it works for YMF719 as well. It has the same executable SETUPSA.EXE as referenced by 'TheMobRules" and all it did was setup the "SET BLASTER" line in the autoexec. Had some trouble getting DirectX working but fixed that. I'll mess with sound on some DOS games later tonight.

That DOS utility does not only add the "SET BLASTER" line to AUTOEXEC.BAT, it should also configure the PnP values for the card settings. For running DOS games, that should be all you need to get it working without any additional drivers (at least that was the case for me).

Thanks. I'll take a look at that. Interestingly enough I've tried Doom and the Midi music works but the other sound like gunshots and other effects isn't working. I assume this means the system is recognizing the dreamblaster S1 but not the actual OPL?
