To Beta 16......just need to run the program and click on Update Available.
 
Couldn't find anything on their site to see what's updated, but I'm sure it's an improvement.

Great!  Thanks Mesh

Just went to update. I already have Beta 16. Have had it for awhile now, but for some reason when I just tried it will not run in 64 bit only 32. tried a few past betas and also can only run in 32 bit. Strange.

Will this thing ever get out of BETA?

That's interesting Dan.....I have the download link in my email, but haven't installed yet. The only reason this even popped up was when I open a project (yesterday) with midi guitar in it, I saw the update available thingy there.
 
Could this be an old Beta installer that somehow got linked with the newer version?

Everyone thinks it....Bapu sez it!!

It has been out for some time http://forum.cakewalk.com/FindPost/3557923
The 64bit stand alone and dll run OK for me.

Thanks Scook.....it's very possible that I have Beta 14 installed and not 16. Will check tonight.

That's exactly what it was.....I had Beta 14.
 
I only installed the 64bit version and in stand alone mode, everything was working. However, under the interface tab after selecting my 2i4 and then click on 'driver', it always crashed Midi Guitar. Not sure if it's my 2i4 drivers issue with Win10 of something else with Midi Guitar & the 2i4.
Of course, it works fine if didn't click on that...lol.
 
Dan, have you tried to uninstall Beta 16, reboot and then re-install?
