Topic: freezing diapason
I am a big KIVIR/Kremsegg fan and user. What I really find difficult to live with is that switching presets will drop the complete tuning, and find myself playing not just in a different temperament, but in a completely different key. I tackle this by freezing the diapason/tuning parameter, but that means in practice that I stay in equal temperament, losing all the charming richness of meantone, kirnberger, etc.
I realize the historical truth in this all, but my modern ears and hands can not cope with playing in one key and hearing another. I should probably duplicate all presets, but it would of course be much simpler to have the option of just freezing the diapason (of the a, or, even better, any key), indepent of the temperament, stretch, etc.
