controling parameters of FM8 from max

I've been trying to sort my way through this for a couple weeks since it seems it shouldn't be too complicated but I'm still struggling so despite not being entirely germane to max, I'm posting this here:
I'm simply trying to control/automate parameters of FM8 through max -- it's easy enough to send pitch information to FM8 either running alone or in Logic but what I'm really interested in is controlling parameters like filter cutoffs etc. Following some tutorials, (http://jsimonvanderwalt.com/2010/02/01/maxmsp-to-logic/) I've been able to get the numbers I need to identify the specific parameters, but these are above 128 and from some posting on a Logic forum it seems this is a technical limit of the system, that there is no real workaround to this approach in Logic.
So here I am. Is there some way to approach this that I haven't considered? I'm not at all attached to using Logic, it's just the DAW I have and am familiar with.
