I never noticed that behavior. Perhaps your hardware is sensitive to "no input" and you forgot pulldowns ? As far as i know the pins are in an inactive state during programming (and they are not outputs!): Neither HIGH nor LOW.My only complaint so far wit the Teensy is that during program upload, the outputs go active and it really jacks with my Sim sometimes when stuff activates when it shouldn't.
How's it going, Rob? Were you able to test the new version of the plugin?
We investigated a bunch of performance complaints since we fixed the prop disc slow-down and nothing has been reproducible. If you think you see a performance problem, please get two clean side-by-side demos (10.36 and 10.40b5) and then add your add-ons to both in lock-step to create a good test case. If you isolate a performance problem that way, then file a bug.
I am driving a relay board with a teensy so I will try the 10k resistors.
