Logic's event list/controller issues

Question

I edit extensively in Logic's event list, and just recently every time I record on keys with a sustain pedal, instead of an on/off (0 or 127 on controller 64) I now get a series of sequential values, about eight per pedal move instead of just one, which as you can imagine, completely muddies up the event list. Controller 64 is supposed to be a switch only controller, that is, on and off. I don't know how this new wrinkle happened. Any ideas??
As always, thanks for all the help.

As you know, controller #64 is defined as a switch controller in the MIDI spec, but the protocol doesn't specifically forbid intermediate values for this and, interestingly enough, other switch controllers as well. It's just that instrument manufacturers have, in great measure, stuck to the implementation of 0 and 127 as the only transmitted values for switch controllers.
Notable exceptions have cropped up fairly recently, particularly with the advent of half-damper pedals that utilize intermediary values for CC#64 to transmit pedal position.
Certain Korg keyboards, such as the Oasys and the Triton, to name two (which, BTW, support half-damper as well) have allowed various synth parameters to respond to intermediate values for a variety of switch controllers, including CC#64, 80, 81, and others. So these parameters will respond to switch controllers as though they were continuous controllers if the controller value data bytes are in-between 0 and 127.
Now, enough of that. On to your thang...
If you enter pedal markings manually in the score editor, or draw in pedal positions using hyper-edit, Logic will sometimes interpret values along the resulting ramps that are drawn (inadvertantly or not) as intermediate CC#64 controller values. I have the feeling that's what you're seeing.
But the intermediate values, though a PITA, are "legal".
