Take an A for exsample. It?s 440 Hz and the next A is 880 Hz. The notes between are diveded logoritmic into 1/12?s of that span. If you now play a chord in a diffenrent key it will be slightly out of tune. A piano-tuner knows this and will therefore tune (detune) the 2 or 3 strings of the same note slightly different so that it will sound good in any key. This is called equal temperment and is actually a compromise to make chords in every key sound equally bad. With pure tuning the Virus calculates the chord and tunes it in to make the notespan excact. You may find pure tuning a bit cold to listen to because our ears have grown used to litening to things that are actually out of tune.
