Control Rate

  outlet_a = 1;
  n = inlet_trig;
  if ((encoderLast == 0) && (n > 0)) {
    if (inlet_dir == 0) {
      if (param_preset + encoderPos > param_min) {
        encoderPos = encoderPos - 1;
      }
    } else {
      if (param_preset + encoderPos < param_max) {
        encoderPos = encoderPos + 1;
      }
    }
  }
  encoderLast = n;
  if (val == inlet_mom) {
    val = !inlet_mom;
  }
} else {
  outlet_a = 0;
}
outlet_o = param_preset + encoderPos;
