convert a string expressing a pitch in Scientific pitch notation into its equivalent midicent encoding. The scientific pitch notation is the notation used in the specification of pitch in events. For example, "A4" is converted into '6900'.

NOTE: the microtonal alteration, as in A#4+50, are supported.

See midi tuning and functions @midicent2hz, @hz2midi, @hz2symb and @hz2symb.
