Notes sustain forever on reason 4! cant turn it off!

sorry about your problem, i have the same issue. i think i solved i'm by using my midisport 2x2. Alesis fucked up on the midi with this unit. use an other midi sort, and that may fix the problem.

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.

These are notoriously unreliable - the contact pads age whether they are played or not.

Roland/Edirol should be able to supply a set of replacements if you can track down a service agent.

In my experience ( in the UK ) their service sucks.

They have an ex-employee who does the warranty repairs from shed at home and that's it!

They won't deal direct with the public and their sales chain can't be bothered to order parts.

Good luck.

Dont forget that the PCR50 is a Midi controller and as such has no "sound" of its own. You must have Midi compatible player or composer type software (like Reason, Cakewalk, Sonic, etc) to link up to the PCR50 to get any sound.

Chek If the driver is infected or not. Infection may be a reason. I you see no infection reinstalling may help.

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 

Yes it is. I have one and have used it on mac OSX from 10.2 to 10.5.

he's wrong you need to change your wdm driver to asio 4 all!
