# 6.17 LADSPA Effects

LADSPA effects can be assigned to either an individual instrument on the instrument's FX tab or assigned to an FX channel in the FX mixer.

Clicking the "**Add effect**" button below the Effect chains box opens the following dialog:

![Add effect](/files/-LuiUvLEx4f2CZn850bG)

Double-click to select an effect. You can narrow the list of effects using the text box at the top (e.g. "filter", "delay", etc).
