writing several parameters at once in touch mode in Logic

Hi all,

I am trying to implement a feature in a AU plugin that allows it to write three parameters at the same time, exactly as the "FilterDemo" example (provided by Apple) does for two. And I am encountering a strange bug in Logic (9.1.1). To make it simple, let's take the FilterDemo example, that has exactly the same problem:

. if I put the track in latch or write mode, eveything is fine, by dragging the mouse in the UI, both parameters (resonance and cutoff freq) are written as they should

. if I put the track in touch mode, here again it's fine, as long as there is no prior automation data in the track. But if there is preexisting data, then the second parameter (in this case "resonance") does not stop writing when the mouse button is released, whereas the first one (cutoff freq) does.

The code is exactly the one from "FilterDemo", without any modification. It was build on 10.6 with 10.5 SDK. It seems that Logic does not correctly handle consecutive "EndParameterChangeGesture" events, at least when the code is written as FilterDemo is. This does not occur in Digital Performer 6.13.

Is there's a workaround to avoid this ?
