I've just patched the firmware using the synth-pcm-dump branch but after i connect to my pc using usb and ran the python scripts/dump_extracted_pcm.py, then it says this:

 Traceback (most recent call last):
  File "<python-input-11>", line 3, in <module>
    from e2sysex import *
ModuleNotFoundError: No module named 'e2sysex'
>>>

Any help is appreciated!
