In the Casio website under this Link is indeed written:
Scale Tuning: Equal temperament + 16 types, Scale Fine Tune ±99 cents
I believe the terms are quite clear when we are talking about scale tuning.
I have bought the MZX-300 but I can not find any scale fine tuning possibility other than those default scales (equal Temp + the other 16 fix ones) under the main setting menu.
Can anybody give some hint, where to find the scale fine-tuning menu? (e.g. to fine-tune the B note to -50 cents)
Thanks
