Hey creap
first off, That was very interesting what you where talking about, the delay compensation system you use, very smart indeed, never knew that existed but it sounds very useful for people not using Protools HD.
Second, I am soooo with you about Protools/Avid. I have M-powered, and that's even more limiting than LE (no bloody complete toolkit, bastards)
Finally, I understand it's frustrating to end up with a DAW that doesn't perfectly fit your purpose, and I wouldn't even think about programming Midi with Protools. I feel it's just not made for that, while I don't really like using anything else for audio (especially in post-production).
But may I suggest Logic 9?
Although you may not be able to use the control surface functions of the 003 (and you never know, some clever geek might have figured a way to translate the Didi control interface to be used by other DAWs), you can still use it as an audio interface, and a rather good one at that... The added bonus is that you'll be able to use the Virus TI plugin (which works nicely with Logic).
Then you can just bounce everything and mix in protools if you prefer (I know I do)
I'm sure you can find a good deal on a full copy of Logic 9 somewhere...
