Interesting and a good idea Bill if you're into editing sounds, but for me it's not what I want to do

Also...

No VH
No SA
No Audio styles
Two boards to carry and setup.
I would need to learn a new OS and for editing sounds on workstation, well it's just not my thing, and would rather pick from the hundreds already on the S950 and more available for sure
Besides it's not like you can't edit sounds on the S950, true not as well as a workstation, but for me, enough editable features to satify my needs
Finally if the built in sounds on the S950 are anywhere near the T4, they will be plenty 'rich' enough

That being said, it's a good thought, a good concept and something to consider. Options are nice, and it drives competition which is a good thing.
