In scaler 2 there was a button to stop sounds triggered from within scaler!

I hava some chords in scaler’s main track. I drop them into my DAW’s track (same track where scaler is connected) .. While I am listening and experimenting, I might like to hear the chords triggered from my DAW, not the ones triggered from scaler itself.
This option existed in scaler 2, why has it been removed?
Now, I realise there are several work arounds like dropping the chords onto another track with another instrument connected, and then mute scaler’s instruments (or use the stand-alone scaler 3), but for the sake of handiness and quickness why remove an existing option?

Not sure what option you are referring to @omar17166 But there’s quite a few ways to mute the internal sound in S3. the mixer, in settings, choosing no instrument, muting the chords etc etc. Much more flexible than S2. It’s worth having a look through the manual, onboard tutorials and also our YouTube videos.
Maybe you are referring to turning DAW sync OFF which you can also do via right clicking the play button.
