    Glad it's of use :)
    The FeatherWing board is based upon this board so also a confirmed design. It's quite useful with NeoPixels, though Teensy is better for anything with a large amount of pixels.

    Nahh. It's all good feedback. C1 is the 10uF cap on the power input, so I added a new cap next to the MLK20 power pins and posted it back to the Git repo. I'm making a board for a customer using this...

    True. The board works well with this layout, but C4 should certainly be moved to Pin 7 & 8. Oversight on my behalf :cool:
    I updated the Kicad files to implement this change.

    Might be worth trying with several cards like i did? I was surprised at how different the output I got was. I'm pretty sure that I tried a Sandisk Ultra some years ago and that did actually play back...

    Correct URL to the Zip file with samples. Also found this thread that mentions Static in playback, so I think it's the same?

    @greg1 Try using a UHS-3 card? I just found that this has significant impact. Using Teensy 3.2, I can now play back 5-6 simultaneous sounds from my SD card.

    The solution became to use the standard Encoder class for Teensy and just ignore one of the three phases in the Hall sensor signal. This looses precision, but solves the problem elegantly as it...

    Thanks @mbogerson! Those posts was quite a dense read, but from what I gathered it boils down to adding this one line to the setup-method (given that the pins I use are on the C-port:
