Hi all,

I have tried for the first time to edit a project on Push 3 standalone that has been created with Live. However, I get no audio output on the headphones.

What I discovered so far is that it is related to the setting of "Main Out" of the Main channel in Live. In the Live project, I have the main out of my audio interface of my computer not on 1/2 but on 17/18 (my AES3 outputs). If I change them in Live to 1/2 save the project in Live and transfer it to the Push 3, I get audio output.

Is there any way on the Push 3 to change the "Main-Out" / headphone output setting of the project?

Settings are part of the .als so everything's normal here.
You can change you tracks' i/o from Push, in the Mixer view. You might need to click the Mixer button a 2nd time to switch between "global" i.e multitrack view and single track view where you'll find the i/o settings.

Hi jur,

I already found this menu but I do not know how to change the output routing there. There is no selection possible under "Channel" - when I rotate the encoder above "Channel" I only get a white bar with a black square in it:


However, if I change the "Type" to Ext. Out I can select another Channel by turning the encoder. I hear, for reasons I do not understand, audio when I select Channel 3/4 (the project has outputs 17/18 configured as "Main Out") when Type is set to Ext Out.

Ah, after some more trying and reading the docs, I now understand that I have to press the "Main Button" (right of the eight lower display buttons) to select the main track and there I can select the "Main Out" and "Cue Out" channels.

However, the Main Out is already set to 1/2 but i hear no audio. But when I set it to 3/4 and then back to 1/2 I can hear the audio. So looks to me like a bug. But at least I now know what to do to let the project work on the Push Standalone.
