# 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](https://2299305010-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LRtsae7H2l0Wn3A4biK%2F-LuiUl_1p-pf6clVhYuE%2F-LuiUvLEx4f2CZn850bG%2Fimage.png?alt=media\&token=02ce4932-7b84-4fd0-9645-721c93a74626)

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).
