MIDI Velocity & Dynamics Calculator

Convert classical dynamic markings (pp, mp, ff, etc.) into MIDI velocity values (1–127) while adding accent weighting and subtle randomisation to mimic human performance nuance.

Musical Frequency Ratio Calculator

Convert semitone intervals into target frequencies and explore how tuning systems affect pitch relationships. Use it when transposing instruments, tuning synthesisers, or comparing equal temperament against just intonation.
