I am having some challenges with sample file management on the GR-1. For almost every sampler I have ever used I just end up making a "sounds" folder and subfolders and dropping hundreds of files in there to experiment with as I work through the creative process. On the GR-1 more than 200 or so files in a directory and the device slows to a crawl. Yesterday I had a sub-folder with 1500 files in it and the GR-1 completely locked up and I had to power cycle it. I am assuming this is normal but maybe it isn't? I am on FW 2.2.2 and am using a Samsung BAR Plus 64GB - 200MB/s USB 3.1 Flash Drive which seems to be super fast on my computer but really quite slow to access on the GR-1. Any help would be appreciated.
