Hey all. I just had a problem pop up. Running producer 8.5 win 7 pro, using a mackie pro control. If I open a sonar project and go to midi devices, I have Mackie usb In/out as choices, I tick the box next to each, click ok, but it doesn't stay ticked. If I go to control surfaces and choose mackie I have no in or out that I can select. I know this is due to the midi devices not staying ticked. Any thoughts? Thanks in advance.

Do you have the latest patches for 8.5 installed? I've never had a MIDI Device get deselected on its own.

Hi Dave. I have 8.52 installed. I just did a new install with win 7 pro. I had it working. Opened a new project, and my mackie wouldn't work. Really weird. As I stated above, In my midi device dialog, I have the motu in & out there. Again, if I check it, then close the box and reopen the dialog, it's unchecked.

Perhaps this maximum usb midi issue:  http://www.cakewalk.com/Support/kb/reader.aspx/20090210

I think it applies to Windows 7, too.

I was fighting the same battle a couple of months ago - midi situation had been consistant for a couple of years (midisport 4x4, moog phatty on USB) added a krog kronos hooked it up usb and my midi devices started playing a round robin of disconnection. 

Read what I could on the interwebs (not a huge topic) got some idea it was a Win 7 issue and went to the 5 pin cable for the phatty and the kronos to keep my midi devices list consistent. 


 

Might as well apply 8.5.3 http://www.cakewalk.com/S...eader.aspx/2007012920, it has more than AudioSnap fixes.

xiwix, Thanks for the reply. I tried the registry fix that you recommended, no luck.. 

Fixed it.. I'm going to post what happened and the fix just in case anyone else ever has this issue. 
Last night I had installed a webcam on the computer. I was going to use the webcam to record live videos of our trio performing in our studio. 
It appears that the drivers that I installed for the webcam for whatever reason messed up the midi. I did a restore on my computer, and all is working fine.
Yesterday I replaced my my hard drives, and installed Windows 7 Pro. So I was in the middle of reinstalling everything.
Thanks for the help guys. Bobby

Thanks for posting the fix. I thought maybe you might have a USB conflict, but I have a lot of USB devices on my computer (4 on board and 2 hubs with 4 each) and never had a conflict. Glad you got it working.
