Bjorn Bojahr WizCalc

The complete assistant, apart from regular calculation processes, WizCalc is telling you how to pitch a loop to the desire length or tempo by means of detecting the new trigger note to play and the correction to do either by fine tuning (-128 to +127) MIDI tuning (-64 to +63), the deviation in Hertz, or the pitchbend wheel controller track.
Converts Sample frames in milliseconds.(both ways)
Converts midi notes into frequency in hertz (both ways).
Cherry on the cake: listings of all MIDI controllers and all GM instruments (General MIDI)
