Hello, so I am attempting to build a drum sequencer using matrixctrl and feel like I am close to figuring out the logistics, but am stuck on one thing. With matrixctrl, how do I get it to output the value of just a single row?

Perhaps it will be of use to explain my logic for this sequencer. But first, here's the very bare skeleton of what I have:

            "box" :             {

                "maxclass" : "newobj",

                "text" : "- 1",

                "outlettype" : [ "int" ],

                "fontname" : "Arial",

                "patching_rect" : [ 174.0, 108.0, 32.5, 20.0 ],

                "numinlets" : 2,

                "fontsize" : 12.0,

                "numoutlets" : 1,

                "id" : "obj-17"

                "text" : "counter 0 0 31",

                "outlettype" : [ "int", "", "", "int" ],

                "patching_rect" : [ 76.0, 146.0, 87.0, 20.0 ],

                "numinlets" : 5,

                "numoutlets" : 4,

                "id" : "obj-16"

                "maxclass" : "comment",

                "text" : "SAMPLE",

                "linecount" : 6,

                "patching_rect" : [ 191.0, 221.0, 22.0, 89.0 ],
