With The Hammersmith's EDO C3 tunings, the higher you go towards EDO C3 50, the more limited the tonal range gets. Is there any way to maintain the tonal range? What I'm after is a quartertone tuning with the same tonal range as a 12-tone tuning.

At EDO 12, a grand piano has 88 keys. If you want an exact quarter tone tuning you need to use EDO 24, but that means you need 176 keys to play the same range as the original 88 keys. MIDI only has 127 keys so you can't play the same range in EDO 24 as in EDO 12, not easily anyway. You could split the instrument over two MIDI channels.

In other words, the more notes you want per octave, the more keys you need to play all 7 octaves.

Thanks for your reply. Would it be possible to expand the range to the available 127 keys?

Not easy unfortunately, as the instrument relies on being restricted to the original piano's range for other reasons.

As an alternative, I've calculated quarter tones (EDO24s) at various other central pitches for you and put them in a folder. This folder can be put inside the Hammersmith / Library / Data / Tunings / folder on your hard drive. Next time you start Kontakt, Hammersmith will have a new tunings folder called "EDO24s". These are all quarter tone tuning centred on each C octaves from C-2 to C8. See if this helps you get what you need.

The tunings are here:

By the way, if you want to make more tuning you can try my Xenharmonium script -- which is not pretty, but lets you calculate just intonations, equal divisions at any central pitch, etc. etc. It's also here:
