The only workaround so far is to clone the existing PX SSD drive to another similar or slightly larger drive but that clone will have the same 150GB and 50 GB limitation as the original drive. But if you then delete/overwrite the Sample Imports including the Factory, User and Addon Samples, you get 200 GB for your Samples and then creating all new Programs in the User Banks which can then be "transferred" with some slight editing of sysex files using MIDI-ox editor) into the Factory and Addon Banks for a total of 512x4=2048 Programs (patches). This is essentially creating a new empty drive that is customized to your needs. And learning to clone the SSD drives also provides for multiple backups. I have 3 SSD drives now that are customized for live gigs, studio sessions and projects respectively. There is not limit on how many custom SSD drives that can be made, with each suited/loaded for a different purpose...just can't have it all on a super-sized drive.
