1. An implantable stimulator device, comprising:

  • a plurality of electrode nodes;

    a first timing channel dedicated to operate with first stimulation circuitry, wherein the first timing channel is configured to program the first stimulation circuitry to provide first current pulses, and to select a first plurality of the plurality of electrode nodes to receive the first current pulses; and

    a second timing channel dedicated to operate with second stimulation circuitry, wherein the second timing channel is configured to program the second stimulation circuitry to provide second current pulses, and to select a second plurality of the plurality of electrode nodes to receive the second current pulses,wherein if an electrode node is common to both the selected first plurality of electrode nodes and the second plurality of electrode nodes, the first and second current pulses are added at the common electrode node when they overlap.
