Yeah, that was my first thought. Make 0.0 <==> 440 Hz, period.

It has been suggested that it be a "system variable" or something, 
but since we have linear pitch control anyway, you may as will 
implement it as an optional TUNING control input on the plugins that 
care. (Sequencers with direct PITCH output and scale converters would 
care.)
