I appreciate everyone's feedback. I've decided to strip down my computer and see if I can eliminate the problem, then work my way back to my current setup, hopefully finding what is causing the process in the first place.
Of note: I'm perfectly aware that Roland isn't supporting Windows 10, and the only way to install the Vstudio 700 hardware is with hacked drivers -- which I used. Actually not really hacked drivers, just altering one of the install files that let Windows know what the files are for, if I understand properly.
The Roland hardware has been functioning just fine in Windows 10 for a few months, and the BSODs are a new development that may have nothing at all to do with Vstudio, but could be anything from CPU beginning to fail, to a power supply that's aging, to airflow problems. That is one of the frustrating things -- this particular crash could have any number of causes, and tracking it down can usually only be done by a lengthy process of test and elimination. The DMP files are unusually uninformative, and have a lot of "unkowns" and blank parameters.
I'm hoping its just a wonky power supply, or maybe bad RAM.
