REW and Edirol UA-1EX: Anyone get this to work on a mac?

The REW Output device can be left as default (input device also), as you hear the test tones OK the output is working as it should. On the input side did you change the default audio input on the powerbook preferences to the on-board line in?

No, I MUST choose the Java output option - leaving it at the default device results in a too low signal (-45 db or so). Setting it to the Java Audio output, I get this:

I've dug out my old Edirol UA-1A and tried it on a Mac Mini running Leopard and got it working OK, so it should be possible to get your Macbook and UA-1EX working.

Steps are:

1 - Before starting REW go into System Preferences - Sound and set the input and the output to your UA-1EX (if you do this after REW has started the input seems to remain as the on-board input)

2 - Start REW, open the settings and check that the output device and input device are both set to Default and the sample rate is 44.1kHz. Make sure the loopback connections are in place from your UA-1EX outputs to UA-1EX inputs.

3 - Try the check levels on the soundcard settings. If you are not getting any input, try selecting the UA-1EX as the input device (in Tiger this wasn't possible, but seems to work in Leopard).

4 - If the input still refuses to work set the REW input device back to default, close REW, go back to System Preferences - Sound and set the input to the on-board line in, start REW again and have another go, but this time looping from the UA-1EX output to the onboard input.

Just seen your previous post (must have come in while I was typing). That plot looks fine, so maybe best to go straight to trying a measurement

I'm having similar trouble, and was wondering if anyone could offer a suggestion. I'm trying to migrate from my old Windows laptop to a MacBook Pro running 10.4.11 (sorry, I don't have Leopard). I have a Native Instruments Audio Kontrol 1 external sound card. I tried using the calibration file from my previous Windows calibration, but the input level is very low. When I set up loopback and try Measure... to create a new calibration, I get output through either the Default Device, Java Sound Audio Engine or M3DMixer, but no input (using Default Device -- using Mac OS X, Core Audio gives an error dialog). I did set the input and output to the Audio Kontrol 1 on the Sound control panel, and I can see the input level bobbing around during the measurement. I also see an input level registering on the lights on the AK1 device itself. Any suggestions for how to make this work?

You can't use anything but the built-in input with 10.4. That is a bug inside Apple's JRE, they fixed it for 10.5.

Hello:
I have a Mac Mini Intel with 10.4.11..and an Edirol UA-25 external Sound Card...
As far as I know, if I understood OK, I need 10.5 to use REQW with a external card (different from the built in)?

Thanks

That's right, 10.5 allows REW and other Java apps to access the inputs of an external sound card when it has been set as the default in the Sound preferences. In 10.4 the outputs of external sound cards can be accessed but the inputs cannot.

Hello JohnM

OK

It is incredible that Apple does not solve this
Thank you very much
