Hi Donny,
I haven't got mine up and running again as yet ( too busy with my other toy at the moment)
But I did ask Dan about sound choice



SD2 / SD1000 any GM synth your VST, your Soundfonts

or our SoundBanks and more to come....

Apparently there are 4 sound banks they 've created, korg, Roland , Ketron Yamaha , they are an extra though, not part of varranger package.

Personally if I was starting over, I wouldn't dash out and buy the sd2, it was the only option 5 years ago , from memory.

I would imagine if I got serious about it again, I'd probably go for his sound banks

Have a chat to him, he's very helpful.
