[maxmsp] Using Max to Enhance Logic Automation

Hi there,

I wish to interface Logic Express with Max (via midi rewire). The following is a very simple example of the type of composition I wish to produce - 

One instrument track in Logic containing a series of notes, 1 minute in length. 
This track contains logics flange effect and the exs24 sampler. 

I wish to adjust the intensity of the flange effect throughout the length of the track in order to generate effects. An example of the nature of this automation - 

>From 0 to 10 seconds : intensity oscillated with a square wave of 5Hz increasing to 10Hz, with an amplitude of 50% (therefore intensity oscillating within the range of 0 to 100%.) 
>From 10 to 20 seconds : intensity oscillated with a square wave of 10Hz increasing to 20Hz. 
>From 20 to 30 seconds : intensity oscillated with a square wave of 20Hz increasing to 20Hz. 
>From 30 to 40 seconds : intensity oscillated with a square wave of 20Hz increasing to 15Hz. 
>From 40 to 60 seconds : intensity oscillated with a square wave of 15Hz increasing to 0Hz. 

The problem - The problem is that this automation would take forever to draw. 

The solution - only draw the frequency of the intensity modulation, not the actually intensity itself, as follows - 

http://baz.perlmonk.org/3.GIF 

And then have a secondary stage where the squareware function is applied to the frequency values.

Of course, since this is a composition, I don't just arrive at the values above in a random manner. I need to listen to my composition again and again to decide what needs changing. For example, perhaps this would work better - 

>From 0 to 9 seconds : intensity oscillated with a square wave of 2Hz increasing to 11Hz. 

If so, I simply change the automation shown in 3.GIF above, without having to redraw many square waves. 

So my question is, do you this it is possible for me to do this using Max as the secondary stage? So far, I have managed to send the automation information to max, via a ctrlin object connect to a rewire object in max - its a start at least. If this is possible, how would you recommend going about it?

Any other alternatives gratefully received. 

Thanks for your help,

Barry.
