    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

While using korg m50 editor using usb data cable there is no sound from my lap.the sound is only from my head phone connected to my keyboard directly?

Are you connecting to the laptop and using it as a midi controller? You can record midi notes from the keyboard and send them to your laptop via USB using any midi sequencer program (reason, logic, etc). Create a midi track, select the input of that track as your keyboard, then hit record to play some midi notes. To hear what you record, you have to set the output of the midi track to whatever midi sounds or instrunents you have installed on your laptop.

If you are trying to record the actual audio sound the keyboard makes, use an audio program such as cubase, sonar, audacity, pro-tools, and either mic the keyboard, or connect one of the other audio outputs (1/4" TRS) to an audio input on your DAW, and record an audio track that way (as opposed to a midi track).

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.

Notes don't stop even after I release the key

The keyboard  is not sending a note off instruction after the key is released. Try checking midi preferences in reason.If your using a Mac check that the edirol is present by launching Audio MIDI Setup utility located in the utilities folder. You can download the latest Mac driver from Roland below: EDIROL PCR-300 32-key MIDI Keyboard Controller :: Download

I have a Technics KN550 and I was wondering if it could connect to a PC

The Technics KN550 has a midi out, so all you need is either a midi to game port or now you can buy midi to USB cables. If you are thinking about this seriously, then you're going to need some sort of arrangement software. Have a look at Cubase which is now the industry standard for PC's. It used to be Logic Platinum but Apple bought them out and they only release software for the Mac now.
The good thing about midi is that once you get into it a bit, and make your own samples or have a sample bank on your PC, you can use use your keyboard to trigger any of those samples, so your keyuboard suddenly becomes every instrument under the sun.
You can find cables by clicking here and read about Cubase by clicking here.

Edirol UA-25 not working on Mac OS X

I had the same problem. When I installed the Edirol software it prompted to 'reboot' and when it restarted all the lights on the Edirol came on.
Why don't you try it like that.
Hook up the Edirol Install the software Reboot
Best of luck Victoria

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.

Playing Roland RS50 through Cubase SE on a PC

Sounds like you may have a MIDI loop. If the Midi I/O Meters on the transport bar ar all the way up then that's the case. Uncheck the speaker Icon next to the track when you are playing.

It's also usually a good idea to have each track set to have it's midi input be just your controller, not "All MIDI Inputs" which it is by default.

Finally, make sure your instrument has "Local Off" configured under its MIDI settings. This prevents it triggering its internal sounds directly and forces everything to go through the sequencer.

If my advice was helpful pleae vote for me!

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
