Once I open midi piano roll, there is no way to re open mixer. Other than closing and starting app from scratch. ---

Do you mean that you cannot open MIDI Editor? Can you give some more details about your system: CPU, OS, DAW… ---

no, its the other way around. I can open midi editor but once it’s open, I can’t close it and open mixer to change plugins, vst instrument etc. anymore. It’s in standalone Scaler 3 for Mac. ---

How do you close the midi editor on Windows? Maybe its a UX problem, and there is some shortcut I’m missing? I expect to just click outside midi clip and see the mixer but it doesn’t work like that. ---

I don’t close it. I just toggle MIDI Editor above. ![image](https://canada1.discourse-cdn.com/flex012/uploads/scalermusic/original/2X/5/543871be28e263bcfeddf31494c1aae3a661a0ec.png) ![image](https://canada1.discourse-cdn.com/flex012/uploads/scalermusic/original/2X/c/c9fea75bd1997eaaabf62e38675fa7c72970929a.png) ---

I have the same problem. But unlike your example, I don’t see any Mixer icon by the keyboard. I do have 3 tracks up. Main, Bass, and Phrases. ---

Hi @woodchuck, welcome to the forum. Is this because you’ve loaded Scaler 3 Control (the MIDI FX plugin format)? If so, it’s normal not to see the mixer, as Scaler Control can’t host instruments - it only passes MIDI through to your instrument. To see the mixer, load the instrument version of Scaler 3 or open it in standalone. If you’ve already done this, please share a screenshot and some details about your setup (OS, DAW, etc.) so we can help you better. Cheers. ---
