### Bug Description

using fill to add 3rd synth melody changes melody on another synth

### Reproduction Steps

1. I have melodic sequences using synth 2 (1 voice) and synth 3 (3 voices).

2. using fill i add another melodic line using the remaining free synth - synth1 (1 voice)

3. select “random+ melody” - fill.

this makes synth 2s melody completely change. if I add steps manually is doesn’t affect the other synth, just when using fill.

### Occurrence

bug is reproducible always

### Found in

_Version_: [1.0. 1]  
\*Build: [1405]

What happens if you stop the playback after you do the fill, mute the filled track that caused the change and then start playback again? Is the melody of synth 2 still changed? Or does it play the expected melody?

If the melody of synth 2 then plays what you expect, what happens then when you unmute the filled track?

I’m asking because it sounds like it may be related to some of [the weirdness I’ve reported as another bug](https://backstage.polyend.com/t/editing-one-synth-affects-the-sound-note-length-of-another-synth/8085).

yes, if I stop and then start playback the other synths melody goes back to normal for a second and then reverts back to the altered one.

if I stop playback, mute the new synth and then play the other synth is normal and doesn’t get affected. if I unmute it the other synth goes weird again.

Sounds like exactly the same bug.

Closing this one as duplicate of [Editing one synth affects the sound / note length of another synth](https://backstage.polyend.com/t/editing-one-synth-affects-the-sound-note-length-of-another-synth/8085/)

Let’s continue discussion there 🙂
