1. A method for controlling neurostimulation charge, comprising:
providing, using an electrode array including a plurality of electrodes, at least two simultaneous neurostimulation waveforms, wherein each waveform includes a plurality of pulses;
determining, for the electrode array, at least one of a charge, a charge density, a residual charge, a voltage and a k value on at least one of the plurality of electrodes;
determining at least one time slot between pulses in the plurality of pulses, wherein the at least one time slot does not overlap the pulses; and
inducing a short in the at least one electrode during the time slot when the charge, charge density, residual charge, voltage or k value reaches or exceeds a predetermined threshold.
