Applying Controller Data

Hi all.

Showing my thorough lack of Midi knowledge, I'm trying to introduce a 'sweep' effect on a 5 note chord using pitch wheel data.

I tried various methods last night but none of them worked.

Due to the chord voicing, each individual note needs a different pitch bend

I tried:

Assigning each note to a different Midi channel, then defining each channel under the edit menu as a 'new' wheel type with the appropriate Midi channel.
I could then access each channel separately in the controller lane and set up my pitch bends there.
Result: all 5 notes would respond only to channel 1 data.

I tried:

Cloning the midi track 4 times then editing their note & controller data via their own prv, setting the Midi channel appropriately
Result: all 5 notes would respond only to channel 1 data.

As a last resort, I simply used 5 separate instruments and set up each note the way  wanted.
This worked as expected but seems awfully resource-wasteful and, to my mind at least, this sort of functionality should be fairly easy to set up.

So, am I missing a trick here?

I did read recently of a vst that allowed you to pitch bend a chord to whatever chord you wanted removing the limitations of all the notes moving up/down by the same amount of steps.
However, im buggered if i can remember where i saw it, now its going to annoy me all day  
I will post the link if i do
