Hi all.
I don't know if this is any use to anyone but, I downloaded a copy of SoundDiver 3.1 from google and installed it on my MSI GL63 8rc laptop on Win 10 pro 64bit. I'm using a Steinberg UR44C for the midi interface and once I installed the software and exited and restarted it. The SD works with no problems.
I just have to re-autherise every so often by reinstallation now and again to keep it going when I want to use it.
There's a whole list of Synths to choose from when you're setting it up, but there are one or two listed which aren't actually actually in there for some reason. My JX8P is one which is a pain. :-(
I do have a Yamaha VL70m, 01W/pro and Roland GR50 I can program with though, so not to bad :-).
Anyway thought I'd just drop by and add my pennies worth.
