i'am reading 9 pins via touchRead() every ten milliseconds.
most of the time all readings are stable in the range from 1000 to 6000.
but sometimes all the readings jump to the range of 1000 to the extreme of 65000 for a while then back to normal.
so 5x or even 10x wider.
i am using the inboard dac. usbMidi and Midi on Serial3.
i swapped the teensy3.2 with same results.

any idea were to look at ? any obvious mistakes ?

thanks !
