  1. Hi Anders, a few to changes to make and its verified. Sounds just like the demos, noisy!!

    There are 28 links, not 27

    470K resistor at M21 to R21 needs to be P21 to R21
    33uf capacitor at W12 to X12 needs to be V12 to X12
    200nf capacitor at T15 to V15 needs to be T15 to W15
    200K resistor at T16 to V16 needs to be T16 to W16

    There may be an easier way to do the above

    Last thing, Speed 1 should be Speed 3 (otherwise it works CCW)
