Default Pro Tools 12 and Motu Midi Bug workaround

Reference: http://duc.avid.com/showthread.php?t=372989

Windows 8.1 64bit, Pro Tools 12.2.1 - New Installation
Motu Midi Express XT - latest firmware and drivers.
I need to work and this is what solved it for me. Until Avid can fix this.

After trying for hours to figure out why my routed midi interface Motu Express XT 8x8 would not accept MIDI IN in Pro Tools, I was able to isolate it to a 3 file combination in the roaming preference folder. They are DSIPrefs,HD Native.pio and Last Used.pio

If I delete these before starting pro tools, my MOTU Express XT usb works every time. Otherwise, it fails and acts silly. Online I found lots of references to MIDI, PT 11, PT 12 not working with certain MOTU gear but no solutions.

It seems that the Pro Tools application performs some kind of identification or binding that recognizes the MOTU driver in full during the creation of these files. If these files exist when you start pro tools, the function that properly binds the MOTU driver is bypassed and becomes partially functional or not at all. I need to work and this is the only solution I was able to discover during my debugging the system.

For the record....
DISCLAIMER: Use at your own risk, you accept all responsibility, this workaround may not fit your specific need and no guarantees are made or assumed. The author is not responsible any negative results.

If you have a similar situation, you can backup the roaming avid folder
before you delete the 3 files.

I created this powershell script to make the deletion easier for me every time I load Pro Tools.

If you want, create a shortcut
Shortcut target: C:\Windows\System32\WindowsPowerShell\v1.0\powersh ell.exe -command &'C:\ProToolsMotu.ps1'
Start in: C:\windows\system32\WindowsPowerShell\v1.0\
In Advanced button, click Run as Administrator.

open notepad (or ISE) and create a file called C:\ProToolsMotu.ps1
Change the ????? value below to your Windows profile name

# Tested in Pro Tools 12.2.1
# Bug in Pro Tools causes MOTU drivers
# to sporadically work post-preference folder creation
# This deletes the 3 files that if exist, trigger pro tools
# bypass something in the MOTU Express XT USB drivers
# replace ????? with your profile name in the $pt_roaming line

# DISCLAIMER: Use at your own risk. Backup your files before trying.

$pt_roaming = "C:\Users\?????\AppData\Roaming\Avid\Pro Tools\"
$del_files = @("DSIPrefs","HD Native.pio","Last Used.pio")
foreach($file in $del_files)
{
$pathFile = $pt_roaming+$file
Remove-Item -Path $pathFile -Force
}
# Load Pro Tools
& 'C:\Program Files\Avid\Pro Tools\ProTools.exe'

# END
