I’m having trouble with the howling system, because it can’t howl correctly.

I have 6 triggers, each trigger changes the variable ‘number’ when you press a number from 1 to 6 or you put the cursor over them.

Then, I have a timeline, lerp and ‘set pitch multiplier’ to a sound file.

Any way to make the transition between pitches smooth?

I also have a video where I show what I want (Minute 0:50): [https://www.reddit.com/r/unrealengine/comments/assia7/how\_can\_i\_do\_an\_smooth\_audio\_transition\_for\_this/](https://www.reddit.com/r/unrealengine/comments/assia7/how_can_i_do_an_smooth_audio_transition_for_this/)
