"there is not enough memory available" prompt when utilizing samson keyboard

Hi,
 
I have I have a 2009 Windows 7 Home premium OS running on a 64-bit Hewlett Packard desktop. An Intel i7 CPU and 7 GB of available RAM.
 
When I try to connect my copy of SONAR Pro with a Samson keyboard I get a prompt that says "there is not enough memory available" under the MIDI preferences in SONAR Pro.
 
Unfortunately, Samson support had "never seen this before".
 
 
 
I have seen some ramblings on the web.
 
One issue being changing Google "Chrome MIDI" settings but I found no such settings in my latest Chrome version when I followed the directions in that web post dated 7 mos. ago.
 
The other post was due to "cheap (music) keyboards".
 
*A key factor here is that I have used the Samson Graphite M25 keyboard before with SONAR Pro and it played without the issue I am asking for help with today.
 
 
Does anyone here have any experience with this?
 
 
Thank you.
 
Sincerely,
 
JWP

Make sure that you don't have another program which acceses your MIDI driver open at the same time. For instance, I get the message if the Arturia MIDI Control Center is opened at the same time Cakewalk is being opened.

I've been using a Graphite 49 off/on for at least 2, maybe 3 years.  I've never seen this with the G49 or any other MIDI device.

Wat?  Chrome's looking at our MIDI data now?  Google you're such a stalker.

I've had this problem with USB MIDI devices, but it has occurred after a crash and when there were still instances SONAR running in Task Manager. It was an M Audio device that wouldn't release after SONAR was shut down forcibly. Had to reboot to clear it up.

This will do what Task Manager can't, avoiding the reboot:  http://processhacker.sourceforge.net/
The option you explicity need that Windows 7 lacks is the ability to kill the entire process tree of Cakewalk in the event of a crash.  It kills everything Cakewalk had spawned and left open in the process, including any hanging threads.
 
Whats nice is the kernel mode driver that allows you to do this.  I use process hacker over task manager any day.  You can straight up replace it as the crash handler, which is nice.
 
To the OP if you have an antivirus suite with a game mode like IOBit ASC, or even an Nvidia driver with a game mode, set the DAW as a game.  All the background crap except what you whitelist and need dissapears while your DAW runs.  If you do it through an antivirus suite you get the added benefit of it running on the secure desktop too, which means everything gets highest thread priority.
 
Steam and Discord shows me playing Cakewalk or GIMP.  But I don't care it works.  Albait a hack but it works.

I had this problem sometime when I rewired my little studio. For some reason Windows does not like it when you plug a USB midi instrument into a different port than it was previously in. I have a couple of KORG instruments which comes with a nice utility to uninstall the MIDI drivers and therefore reuse the ports.
I understand you can use this even if you don't have any KORG gear, just download the KORG USB drivers and there is a utility called KORG MIDI Driver Uninstall Utility, just deselect the option to configure KORG gear only.
