Question about Edirol UA-25 External Sound System

1 Answer

No sound being picked up by Edirol


Im running a mac os x. The edirol ua-25 is not picking up any sound. The lights are on the control panel and yet I am unable to make any sound recordings. I have reinstalled the driver and this does not seem to have worked. I have tried the edirol on another mac (same os same settings etc) and the problem persists. I have even changed microphones and used a second edirol and still no joy.

Do not get MIDI signal via EDIROL UA25

Midi is data only, there is no actual sound to the midi tracks themselves. They need to be assigned to either a software synth or an external synth to actually make the sounds you want to hear.

For instance if you load a demo of a midi sequance you will need to add a software synth such as the TTS-1 or Roland sound canvas which are general midi compatable and will play the instruments sounds assigned to the demo's midi channels. Use the Synth Rack feature in Sonar to open one of them. Then you will need to assign the output of each of the midi tracks to that particular synth and you will get sound. Make sure to assing the synth's audio track to you UA-25 as its audio output.

I would suggest reading in the manual and following the tutorials included in the manual to get yourself familier with how this is all done. spacer.gif

No power to Edirol UA-25 usb audio capture, the unit was working and now I cannot power unit. When I connect to PC I recieve a error message about a power surge has occured, could this be a fuse problem? I...

Connect it before powering system. The usual cause of no power on this is improper software configuration or assignment in the PC regarding the sound devices. It is NOT a "fuse" problem.
Make sure that when you go to "Sounds and Devices" in the control panel that the "Voice" tab is shown assigned to the UA-25. If not, make sure it is in the list of devices and assign it as default.

try this to make sure that the driver was installed correctly.:

Note: Do not use the “Add New Hardware” Wizard in the control panel. Follow the steps below to install your driver correctly.

1. Plug in the USB cable and power on the device – the New Hardware Wizard will start up (wait for it to start).

2. If Windows asks to connect to Windows Update, click on “No, not this time” and click on “Next.”

3. Select “Install from a list or specified location” and click “Next.”

4. Select “Include this location in the search” and Browse to the folder containing your driver (either on your CD or the folder you downloaded). Click “Next.”

5. Click “Continue Anyway” when the Windows Logo testing screen appears.

6. Click “Finish” when the Completing the Found New Hardware Wizard screen appears.

At this point, you may need to reboot your computer. After restarting, you should check to make sure the driver was successfully installed. Go to Control Panel / Sounds and Audio Devices and make sure your device is listed under “Sound Playback” and “Sound Recording” for audio devices and “”MIDI Music Playback” for MIDI devices. You should also check in the Device Manager to make sure your MIDI or Audio device is listed under “Sound, video and game controllers” with no problems (such as the yellow exclamation point).

If everything is successful to this point, Windows has installed the device correctly and is making it available to any software you need to run. If you can not see your device in your software, you should first try re-profiling the device (different software programs do this differently). If this does not work, you may need to uninstall and reinstall the software. If you still do not see your device, you may need to contact your software vendor for more help.

- Mac OS X -
1. Make sure the Roland/Edirol device and any non-essential USB devices are disconnected.

2. Run the *.pkg installer from the CD-ROM or downloaded driver and follow the onscreen installation instructions. When finished, reboot fully.

3. Plug in the Roland/Edirol device. Ports should now be available in software (you can verify driver availability in Applications > Utilities > Audio/MIDI Setup > MIDI Devices).

- Mac OS 9.X -
Users must first decide if they want to run OMS or FreeMIDI, which can be downloaded from the World Wide Web. OMS is recommended. See the OMS or FreeMIDI documentation for installation and activation details.

Double-click the Edirol installer and follow the onscreen installation instructions.

Note: If you continue to have problems, you may wish to consider upgrading to OS X, as its Core Audio and Core MIDI features make this operating system an excellent base for music applications.

Pop/click/dropout is often a buffer size problem. Be sure to check your Buffer Size setting. You'll find it in the Edirol Icon in System Preferences or in the Control Panel of a Windows machine. Increase your buffer size until the problem goes away.

There are also several settings you will want to make in order for audio applications on a Windows XP computer run optimally.

A computer has line out and that means sound out from the computer to your speakers. A line out can also be connected to a recording device or a pair of speakers with an amp built in. Line in on a computer can be used to record audio from other equipment such as a Dj on his decks to record his set. It can also record audio from mp3 players etc. Line in can be used for mic's and also you can use mic in as well. To record any audio onto your computer use line in. Line out can also used for headphones and the mic will plug into mic in so you can talk online.
