If you want to retune Crossovers to CT I suggest you tune 5-draw up one semitone until it gives you a reading of +2 cents relative to 3-draw. 5-draw in CT is a fifth above 3-draw and I always tune a relative fifth 2 cents higher than the root. Everything else can stay just as is. Steve Baker www.stevebaker.de www.european-music-workshops.com www.harmonica-masters.de
