The main out of the minibrute is mono, so there’s no need to connect it to both the left and right inputs of the Keys. Just make sure to set up the panning on the Keys Ext In page.
If you really wanted to split the minibrute output in order to have different effects on each channel, you could use the mnibrute’s headphone out jack, which is stereo.
When i close the analog key the righ in works fine all project .
But in my project for exemple bank a 1, i need to press play to launch the sequence and after i can use the left in .
but if i change the project the left in work fine every time
