Due to DSP capacity limits, you may not be able to insert or overwrite an effect, even when the number of connected effects falls within the limits. If there isn’t enough DSP capacity, the icon for the effect you’re trying to newly place in the chain is greyed out, and you cannot place the effect. To place a new effect, you must delete an existing effect.
