PC drivers have been available from the date the EMI 26 was launched, but Mac drivers have only just been released, which made me keen to give it a try. On Windows platforms, the EMI 26 supports Wave Driver (MME), Direct Sound, ASIO and EASI, whereas on the Mac, it currently works with ASIO or Mac AV. Mac OS 9.2 or higher is recommended, and Logic users will need to upgrade to version 4.7.3 to run the EMI 26. Driver installation is via a straightforward installer routine, after which the computer needs to be restarted so that the newly added system extensions are loaded. It is important to do the installation without the EMI 26 connected, according to the manual. Similarly, if you need to switch from ASIO to Mac AV, there's a driver switch control panel to facilitate this, but it prompts you to unplug the EMI 26 from the USB port before doing so. This is apparently a problem Emagic are trying to fix, but at the moment, you have to live with it.
Emagic Emi 2 6 Driver For Mac
The A62m driver provided with the device has not worked since Mac OS-X Lion (10.7). I have written a replacement driver for Audio and Midi usages, from Lion to present (Catalina). The audio outputs and midi work well, however there appears to be an issue with the audio inputs on Sierra and later. Sadly there is nothing I can do about this. Apple slowly remove functionality for old devices;eventually we will all have to buy new audio interfaces.
To install the driver you will need to obtain and install files as detailed below. When finished you will have files installed as follows. Notice that the A62m file has moved to a new (hidden) location (October 2019). This was a requirement for Catalina support.
Du brauchst ein USB A-B Kabel um das Interface mit dem PC zu verbinden.das Mikrofon habe ich über einen Preamp angeschlossen, welcher wiederum über Cinch Stecker mit dem EMI 26 verbunden wird.Treiber gibt es auf Man wird zu einer Seite von Apple weitergeleitet, dort findet man Downloads für "emagic branded hardware". Dort findet man übrigens auch ein Manual im PDF Format ;)
With the USB Audio Quattro, this results in very strange behaviour: appsthat use the OSS compatibility layer can play sound on your device, butit becomes completely distorted once the loudness goed up. Apps that useALSA directly will complain about device drivers not being found andsuch. You have been warned!
Once the snd-usb-audio module is loaded, you'll see the 'Power LED'control in alsamixer. Muting it will set the LED to Blink and unmutingit will set it to On. For the volume knob, you need to use the alsa_usbdriver with lirc. Lirc will receive events whenever the volume knob isturned or pressed.
Takashi Iwai wrote: right now you can finda driver for USB audio on cvs. It's in alsa-driver not in alsa-kernel.The driver will be built automatically when CONFIG_USB is specified inkernel config. Please note that this driver is EXPERIMENTAL andTENTATIVE. My first plan was to implement a USB library layer onalsa-lib, but it was found out that implementation of isochronoustransfer via usbdevfs will bring some difficulty. So I started codingof a normal kernel driver at first. If any feasible solution to portsuch a stuff into user space, we should do that. But anyway, it's goodto have a working code. We can move it to other place later.
So far, I've tested only audio playback on my speaker, which is adaptiveout without pitch/freq setting. xmms is working. The driver acceptsthe period size up to 1ms. A courageous user can try such a heavycondition. (me? did not yet :) 24bit/96kHz should work, too, but I haveno such a hardware. Besides, capture is not tested at all.
If you have a usb audio device, please test once. (oh, I forgot tomention the driver name - it's "snd-usb-audio" quite easy, isn't it?) Ifyou find somewhat strange behavior (especially in mixer controls),please send me the output of lsusb. BTW, when you use snd-usb-audiomodule, please make sure that you don't load OSS audio.o together.Hotplug likely loads both modules at the same time.
This appendix presents all of the driver modules and their version information as shipped in the current version of UEK R6 (x86_64). This appendix is generated automatically. Note that driver versions and available drivers may change in subsequent errata releases, but the driver versions will always be the same or later than presented here.
The upstream Linux kernel is unifying version management for in-tree kernel modules, effectively deprecating kernel module version numbering. Many vendors are adopting the new model and driver versions may no longer be accurate, or entirely removed in the future. Note that this appendix may be removed in subsequent UEK updates. 2ff7e9595c
