CyborgPerformanceSystem.txt

Hardware:
  Box:
    Every piece of the system fits into a standard carry-on size box which clamshells together
    The top contains the drum machine, mixer, reverb, and synthesizer
    The bottom contains a guitar pedal board and an integrated midi controller
    The box has legs that elevate and offset the top above the bottom
    The box has a single power input (110V AC) and most power adapters are safely hidden inside the box
      The box has ventilation holes for the power adapters
    The box has wheels and a handle to move it easily

  Integrated Midi Controller
  
    User input:
      5 Footswitches built into the base of the pedalboard
        1. Prev pattern button
        2. Play/Stop button
        3. Next pattern button
        4. Undo button (for guitar looper pedal)
        5. Tap tempo button
      2 External footswitches to control mic looper
        1. Switch to sync mic looper with downbeat of approaching measure
        2. Switch to create harmony pyramids automatically (not yet implemented)
      Expression pedal control via modded wah pedal
        When the Wah effect is not active, the user can control the energy of the drums via the wah pedal
          3 energy levels of drums are available:
            Pedal fully back: Just bass and snare are audible
            Pedal in the middle: Bass, snare, closed high-hat, and synth part 4, are audible
            Pedal fully forward: All instruments on the drum machine are audible
        The wah effect functions normally when engaged
        
    Microcontroller: Arduino
    
    Outputs:
      Midi out to drum machine
      Midi out to Infinity Looper
      Mic looper switch control (connected to loop and stop buttons inside mic looper)

      Knobs for Preamp level, main level, eq, aux (reverb) level, for each input channel
     Outputs:
      House out
      Aux out (to EHX Holy Grail Neo)
  
  Guitar pedals:
    Modified Dunlop Crybaby Wah Pedal
      Inputs:
        TRS (Tip, Ring, Sleeve) from guitar (bass is on Ring, guitar is on Tip, sleeve is grounded)
        Pedal to control expression or wah effect
        Switch to toggle between expression and wah effect
        5V in from microcontroller
      Outputs:

        Two momentary footswitches
      Outputs:
        Two channel TRS (Tip, Ring, Sleeve) to midi controller
      
Midi Controller Software:
  User controls 7 footswitches and 1 expression pedal on the midi controller hardware
    
    The user will commonly navigate to a prepared pattern with the next pattern and previous pattern buttons before beginning a song
    The user will stomp the tap tempo button in time to set the tempo on the midi controller
    The user will stomp the play button to start the drum machine
      While playing, the software will send 24 realtime midi sync messages per beat
    
    The user can trigger the onboard loop footswitches on the Infinity Looper to start a synced loop and can depress the undo button on the midi controller to start overdubbing that loop.
    After the user has overdubbed on the Ifinity looper, the user can press the undo button on the midi controller to undo and redo the last recorded overdub.
      The midi controller software only needs to send the undo command to the Infinity Looper which will change its behavior based on it's own state.
    
    To record a synced loop on the mic looper, the user presses the first external footswitch and the software will automatically time a trigger of the mic looper on the first beat of the upcoming measure
    The mic looper does not stop on global stop(but it could be programmed to do so)

    The user can rock the wah pedal (without activating the wah effect) back and forth to access 3 different mute states on the drum machine to achieve different energy levels for the drum beats during playback.
    One digital pin on the Arduino of the midi controller sends 5V out to the potentiometer of the wah pedal (when the effect is not active)
