Hello my name is matthieu.

I have been using Reason for a few years now. But recently I got a problem that is preventing me from using it. I am quite desperate for help.

Here it is.

I am using Reason 4.0 on Acer Pc with a simple Evolution Midi Keabord


I bought it from a friend and it didnt have any drivers.

I used this keyboard to control the sounds from Reason for a long time without any problem.

But recently every time I plug the keaboard on usb this message appear on Reason

"MIDI problem
The Midi port may be in use by another application"

and the keyboards just doesnt work.

I have 2 other messages when opening Reason :

1 "MIDI input problem
One or several MIDI inputs cannot be opened. They migh be in use by
another application. Open the preferences dialogue and check your MIDI
settings"

2 "Reason couldnt set up the control surfaces properly ..."

Ive had those 2 messages before but I was able to use my keyboards.

I am not using another music software working with the midi controller and have no idea what to do. I have reinstalled reason, I have tried the MIDI Ox software but when I select my usb keyboard it says "undefined external error"
And if I go into Preferences > advanced control and select my usb keyboard on the MIDI clock sync I get the same message "The MIDI port may be in use by another application"

I am desperate here and have no idea what could cause this even less how to fix it. This situation is crippling me very much, I have several projects that I need to finish very soon and cannot do it without Reason.

Does anyone know what i could do? I should add that I am really not confortable with computer language and very technical stuff, Im not very good at this and dont understand much.
But please, I desperatly need help!!

Thanks in advance
Matthieu

If MIDI OX doesn't recognize your keyboard, the problem isn't in Reason, but in the drivers.

1) Look up the model of your keyboard (e.g. MK-249) and install the latest drivers from the M-AUDIO site (http://www.m-audio.com/index.php?do=support&tab=driver). If you're on Windows, here's a direct link http://www.m-audio.com/index.php?do=...drivers&f=1088 (don't bother filling it all out, just scroll down to the download link)

2) Try plugging your keyboard into a different USB port. Sometimes ports get damaged or cannot source enough power.

Well, the keyboard is recognised by my Pc and it appears in the list of MIDI inputs on MIDI OX but when i select it it says undefined external error.

I installed the programm from your link. Now when i open reason the 2 first messages before starting appear, but not the last message "allready in use..."

but the keaboard is stil inactive, and if I select it in advanced control the message comes back.

and also, after installing the M audio programm I cannot find anything in the programms bar or anything

hello

did you ever find a solution to your problem?? I am having the exact same issue. thanks

If you aren't getting the "Already in use" error anymore, you might want to try re-detecting your keyboard in the preferences.

The problem may be resolved, and just need to set it back up?
