    EuclideanSequence(3, 5),
    EuclideanSequence(7, 11),
    EuclideanSequence(2, 3),
    EuclideanSequence(6, 8),

]

oe = OctoEuclid(slots) # 8 slots max!

>>>

... then do stuff on the BeatStep.

Controls

• start/pause: start/pause euclids
• stop: reset all euclids
• drum pad 9: manual (or sequenced) step
• top row of knobs: rotate one euclid (control mode only)
• bottom row of knobs: reset one euclid (control mode only)

Notes/TODO

• rotate knobs only rotate forward
• MIDI channel 10 hardcoded
• Use clock input?
• This is alpha, it'll probably change a bunch
• A bunch of other stuff probably
• FUN!
