Patches and discussion for Ensoniq VFX family

Hi there all. I'm a long time lurker who has never posted before.

I had an ESQ-1 which I loved, so I got a VFX-SD...then promptly stopped using the ESQ cause I was SO head over heels for the VFX-SD. I love the sequencer, the transwaves, the dark, cave-like, 80s drums, I love them for being crappy even.

My VFX-SD never had any Keyboard Calibration issues, until maybe a week ago. And then, all of a sudden, I get the blank screen. If I push a button, letters appear... but I don't really want to trouble shoot. Besides, I am NOT good with solder irons or anything like that.

One option is to have it fixed. I know a guy. But I can also get a TS-12 locally. Also, I guess I can wait for an SD-1 to pop up on eBay.

Does the SD sound identical to the VFX-SD? Are there any other differences, like amount of programs? How does the TS sound compare to the VFX-SD? 

Thanks everyone.
