    Fantastic synthesizer unit

    I was very surprised at the number of unique “instruments” and sounds that this unit provides. The documentation on M5Stack was somewhat lacking but the data sheet provided enough info to get this unit programmed. I found UIFlow wasn’t very helpful in programming this synthesizer and much more could be done by M5 to help basic “programmers” like myself, particularly as I am trying to introduce my grandson to graphical programming. All this said, this unit has a lot of potential.
