    Hi, Can you explain to me why this simple patch doesn't work ?

    } ] }
    }
    If I cut the signal between the VSTout and the matrix object everything is perfect ... I don't understand ... Thank you.

      Please use "Copy Compressed" to post patches here.
      You can't do a feedback loop like you do. You should introduce a delay between vst~'s output and matrix~'s input . The way to get the shortest delay (which is one vector long) is to use a send/receive pair: a delay will be introduce if needed.

      Sorry for the "Uncompressed" paste ! Thank you for the answer. That works.
