Hey there Steve, hope you're doing well.
Often using shift and dragging allows you to have finer control over knobs so I thought I'd try this in OTT. However, when I tried to Shift+Click, the plugin seems to alternate between minimum and maximum values for the respective knob. This is especially troublesome on the In Gain and Out Gain knobs and gave me a good scare the first time I tried this as it alternated between -48 and +19.1 db. The knob itself also doesn't move when you do this which seems like a bug.
Any chance you can change this behaviour? Getting an almost 20 db gain boost just by Shift+Clicking a knob seems a bit wrong to me.
