    Audio System Design Tool for Teensy Audio Library GUI [BUG]

    When using filters, if/when the low-pass output (EDIT: narrowed it down specifically to the low-pass output) from a filter remains unconnected (i.e. not connected to another device), when you take the text exported from the GUI & try to import it back into the GUI, an error ("wires[w2] is null") is reported and any patch cords after that error are not restored.

    See the following post for a specific example which demonstrates the problem, as well as a suggested workaround:

    Note: All of this was done using the online Audio System Design Tool for Teensy Audio Library GUI, so nothing here is dependent upon Teensy version, Teensyduino version, or Arduino GUI version. However, to be exact, I was using Firefox 76.0.1 (64-bit) under Windows 10 Pro version 1909.
