I think the problem lies in the very essence of Airteq, which works through physical modeling rather than conventional oscillators. The response of each pipe for each note is different, and this happens at the model level, just like with real pipes. Therefore, in a way, there is already a sort of built-in keytracking within the model itself.
If you add keytracking as a modulation source, unpredictable things can happen. What works for a specific pipe in a certain register won't necessarily work with other pipes and/or other registers, as they respond differently to the same envelope times, air pressure, or whatever parameter you are modulating.
Having said that, I will now say what I have said other times before: dear creators of Airteq, if this is more or less the case, I personally wouldn't mind taking the risks of that 'loss of control' over the results. I wouldn't mind a certain ethical flaw regarding what physical modeling is supposed to be either, as we have seen so many times that interesting results have been achieved by pure chance. Happy tweaking!!"

For what I'm trying to do right now, yes - the particular patch I was working on needs to shorten all the envelope times with increasing pitch, to keep the length of time air is supplied in a constant ratio with the response time of the pipe.
In general, though, I think including note number as a modulation source is probably a cleaner way to solve more problems for more users. In the process of refining a patch for performance use, slight modulations by note number can be useful across essentially every parameter on the entire synthesis engine. (For an example, in a patch I put together or find as a preset on a more traditional software synth, I would fully expect anywhere from a fifth to a half of the modulation links total to have note number as their source!) Besides, if your target user is mainly familiar with synthesizers, note number as a modulation source is the standard way to accomplish this kind of voicing across the keyboard; it's what they'll expect. On the other hand, if you're instead going for more organists who are interested in synthesis, I can very much see the reason to do things the way you are suggesting here!
