FIRMWARE - v0.1.02

* Swap L/R faders
  Left fader pair are "FX Input" from host (aka Output from USB host -> DAC)
  Right fader pair are "FX Output" to host (aka Input from ADC -> USB host)
* Digital-mute DAC signal when bypassed. 
    Bypass mode should just send the pedal input to output. Don't also want a 
  contribution from audio arriving from USB host.
* Don't send post-fader ADC input to output when bypassed. 
    Bypass mode should just send the pedal input to output. Don't also want a 
  contribution from post-analog fader audio being sent to USB host. Only do 
  this for Audio Interface mode.FX Host mode does not allow Direct Monitor
  because it will introduce a feedback loop path through the external effects.

FIRMWARE - v0.1.01

* Works with Big Muff Pi v1.0.70 Plugin so all features can be tested - just

  with up-to 12dB gain

  Big Muff Pi pedal firmware shipped with the BP plugin!) then update.

  Red when connected to host.
