what am i doing wrong here? i'm trying to hook up matrixctrl to pattr. but when i do it restricts it to 'one cell per column' which is not what i want. i want to be able to use as many cells as possible at the same time.
You have a feedback loop. Disconnect the connection between matrixctrl's outlet and pattr's inlet. The connection from pattr's central outlet is sufficient to create a two-way transfer between pattr and the attached object (there is, in fact, no data passed via that outlet -- it's just used to create a "bound" connection between the pattr and the object).
