I had a hard time getting sweetcase too. The facebook link works but I didn't have an account, I ended up using my wifes account and then it worked. I've looked at a lot of rhodes and this one does sound beautiful. It irritates me though because every time I close it down it resets it's settings to default, so I have to remember to open it every time and adjust things. I just bought Velvet 2 and it's pretty nice for 15 bucks, lot's of adjustments and presets but it doesn't sound the same as sweetcase. Not a lot of settings with sweetcase but it has the ones you need, no more.
Don't know if it's been mentioned but GK amplification is a pretty good bass amp and cab for free, I use it on everything.https://shop.audified.com/products/live-guitar-and-bass-bundle-le
I like using it with this freebe: https://www.meldaproduction.com/MEqualizer to dial in the EQ.
