...I just picked up an MPC One, which you could argue is not THAT much different than a traditional DAW, but it kinda is. It's a much more immediate workflow.

Talking of AKAI, I bought a simple MPD218, which as a non-musically skilled person was an impressive step up in comparison to using a midi keyboard with Reason, with a different interface I was offered a new means to input notes and my tracks improved. This is part of the way I see Eurorack too, its a totally new interface with a totally new way of inputting or creating notes.... In short, Brilliant Fun!
Though I doubt I'll be able to program Ba-Ba-Black Sheep on the Eurorack like I could play on the Piano ;-)
Its like, User-Interfaces for life, not all interfaces work for all people, so if one particular interface helps create enjoyment and benefits one person then thats a happy win :)
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
