    I have driver 2.2.2 installed

  • Mr Rhoda May 25, 2008

    Thanks for the reply guys, but I think I need to scetch more detail regarding this problem.

    My mac `OS 10.5 is picking up the edirol as per usual via the usb cable. I am using the latest cubase with the latest cubase drivers. The edirol driver is version 2.2.2 which is the latest one i could see on the net. `I have a midi controler plugged into the edirol's midi in. It is a proper midi cable. I'm trying to host the midi on cubase which used to work fine. Now cubase is just not picking any midi up from edirol. If you look on device setup , there is absolutely no midi to work with.

    I have garage band installed as well and it also not picking up anything. Even if I swap my buddy's midi controller and cable, still nothing. Audio which is coming from the same edirol is picked up by cubase.

  • Mr Rhoda May 25, 2008

    Thanks buddy - but I have 2.2.2 already which is supposed to be the latest one for my machine - MAC Pro Quad, 3gb ram , OSX 10.5 leopard. - it's really baffling - i swapped my friends midi controller on the Edirol's midi input, and still nothing.

    Cubase is supposed to pick it up in Device Setup but neither Cubase , or Garange Band does.

  • Mr Rhoda May 25, 2008

    ps, this whole thing occured after I used the edirol on another computer and brought it back on the mac. I checked on sound preferences on the mac and the mac itself does pick up the card

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. Do not get MIDI signal via EDIROL UA25 - spacer.gif

Hello Sir/Madam,

This is the system requirements of your midi. First check out u fulfill or not?


  • OS: Mac OS 9, 10.2 or later
  • Computer: Apple Macintosh series with on-board USB port
  • CPU/Clock: PowerPC G3 400 mhz or higher
  • Memory(RAM): 256MB or More
  • Hard Disk: 200 MB of free space
  • OS: Microsoft® Windows® XP Home Edition/ XP Professional /2000 Professional /Me/98 Second Edition
  • Computer: Windows® XP Compatible PC
  • CPU/Clock: Pentium®, Celeron®, or Pentium® compatible processor 600MHz or higher.
  • Memory(RAM): 256MB or more
  • Hard Disk: 200 MB of free space
Try downloading and installing the latest drivers from Edirol's website instead of the drivers that came on the CD.

The current setup is to use USB to connect the
Edirol UA-25 to the computer and 2 midi cables to connect the Edirol
UA-25 to the PCR M30. When using a VST instrument I have selected the VST instrument as the
output and Edirol UA-25 MIDI IN as the Input. So in theory this
should work. The Edirol UA-25 is definitely working and having troubleshooted I can
actually hear Midi through it ie using headphones connected to the
UA-25 device. But the Edirol UA-25 does not appear to be receiving
any signals from the PCR-M30 keyboard. Without the Midi cables I
would as you say select the PCR as the input and again the VST
instrument as the output but the reason I am using the MIDI cables is
so that I can record MIDI via the keyboard through the Edirol.
Possibly there is an issue with the keyboard or the cables are faulty
etc. From what you have said it sounds as if I have ctually selected
the correct ports (and there are n't that many other options - all of
which I did try as well just in case) so I am going to need to
troubleshoot this to find out where the fault lies. I think the
logical thing for me to do is to find out whether the keyboard works
if use the PCR as the input as opposed to Edirol MIDI in.

I can't see any reason for two MIDI cables. Connect MIDI Out of the
keyboard to MIDI In of the interface. Some people find it intuitive
to connect In to In. They are in error :-)

Check that your MIDI cables ARE MIDI cables, not audio cables. Same
plugs, different wiring. Or connect the keyboard using its USB option

Good Luck

Edirol not able to record on Cubase essentials

This interface works fine with other hosts but with cubase is more tricky. But you can fix it.

You need to disable the onboard sound card, also use the UA25 Asio drivers, go to programs/Steinberg cubase/ ASIO multimedia setup and you should see the UA25 outports are active and that the sync ref "YES" also that the UA25 Input ports are active. the next bit is a bit of fun select the Advanced options and select Detect buffer size, when thats finished select Check Buffers and Sync, press the start button and the test will run,if everything is ok you should have zero "Sync lost" and zero "Buffer lost"
Depending on how lower you want to get your latency , you may have to tweek the UA25 driver settings and re-run the setup above.

No midi sound

In sonar go to the options menu and select: Audio -->advance. and from the list select the "Asio" driver, then you'll have a new midi output (synthe sw...) select it to have a sound while playing MIDI files.

TASCAM 144 is not a soundcard, but an audio interface

You are correct, there is no "voice generator" within the Tascam US-144.  It can simply transmit the very primitive note-on note-off type data to a Sound Module or keyboard (like a Roldan SoundCanvas), and then that would generate the actual waveforms.   
A SoundCanvas would suit your needs well, as you could run the midi out to this voice generator, and then run the stereo output of that back through the Tascam and into the computer for recording.

Edirol ua-25 not detecting midi but audio works fine


On the back of the UA25 there's a switch called "Advance" - this needs to be set to ON for the device to work as a MIDI interface.

UA101 and Blue Screen of Death

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.

Midi OUT has "holes"

Midi out on your soundcard to midi in on your keyboard. Midi out on your keybaord to midi in on your soundcard It's a lot to do with audio drivers,asio drivers are a lot better than standard realtec drivers. A lot depends on your cpu memory etc,midi sends more than just one note at a time I can play all ten fingers on midi and that's with really powerful virtual synths. Cpu memory drivers all effect audio and midi
