Sorry, spalding, but you seem to be determined to do things the hard way...

Firstly, no sequencer editing if possible, all played live, no edits, yada yada yada... And now, no use of a computer sequencer, only the built-in ones for you, apparently. Fascinating. Very old school. I guess you use what you get comfortable with, but for the life of me, I can't see how working with a built-in offers any advantages over a computer sequencer, and I can name several editing options available in Cubase that exist in no hardware arranger sequencers, that I use on a daily basis. Groove quantizing, conditional edits, positional edits, amongst many others. Then there is the issue of a completely ungraphical interface...
As my arranger and other keyboards sit around my computer rig, I can't for the life of me think of one good reason to use the crippled, unintuitive and poorly displayed sequencers built into arrangers these days. It's all about speed, and I guarantee I can fly around on Cubase MUCH faster than any hardware one.
Is there some kind of philosophical reason you prefer hardware sequencers, or is it just familiarity, and lack of desire to try newer methods? I USED to use hardware sequencers, but the day I got Cubase, I have never used one since!
