I know that Roland has 128 voice polyphony on the XV line but it doesn't have the sequencer, which is what I'm interested in right now. The point is that all these features would be nice on the same machine.
As for EFX processors for every track on the sequencer, there IS a synth that has it (the one I'll probably end up getting). It's not a real widely known manufacturer in the US but they are huge in Europe. Anyway, it's the Ketron SD-1 which has almost all the features I mentioned except for 64 voices and (I think) no Smartmedia. You may ask, why am I bringing this up on the Roland board...because I trust Roland quality and I would rather have them come up with one of these dream machines. (By the way, the SD-1 is 32-part multitimbral and has 16 tracks on the sequencer. That's a lot of processors.)
You're right about the mini CD. I didn't think of that. Thanks for your input.
