MUXMul.A SuperCollider UGen that creates a MultiPlexer Multiplier. By default outputs a 100 channel array of 0s. Receives an input. If the input falls between 0 and 100, it will output all 0s except a 1 at the index of the floor of the input parameter. If the input value is outside the range of 0 and 100 the ugen will output all zeroes.
