There is nothing wrong with the Roland soundset in the VA series, or even in the G1000 - both sound great, right, Fran?
What we need is not more sounds but the easier access to them - give us the G1000 with extra buttons for sound and style selection, programmable one-touch settings, a bigger screen with high density of information (like Fantom's), and a decent vocal harmonizer. Ditch the floppy and the ZIP in favor of the memory card, better still give us 2 slots. Provide USB2.0 digital audio connection to the PC, to enable multi-channel digital audio transmission. Give us programmable super-tones, and forget the VariPhrase or make it support decent-size samples. Move jotstick above the keyboard.
This will move Roland to the front of the pack.
