Check your Input level
The Input slider to the bottom left lets you attenuate or boost your signals’ input level into Finisher. Use this control if your signal comes in too low or too hot, as most effect modes need the signal to be at a certain level to work optimally (e.g. distortion, compression).
The Input level is optimal if the signal peaks stay just under the top end of the meter. If the Input sliders range isn’t enough, find a Gain plug-in in your DAW and plug it in before Finisher MICRO.
