Is this thing velocity sensitive? It doesn't seem like it.

However, it's crazy cool. I think this is the first step into creating a justly tuned instrument for chord changes!

@JoshWMyers you are correct; there is no velocity sensing on the TPX line. Thanks for checking it out; it was in fact the idea of extended Just Intonation chord changes that got me started on the whole project : )

@DrizzitDudden02 The size of diatonic half steps being larger, smaller, or the same size as chromatic half steps is a product of the tuning. In 12 equal divisions of the octave they are the same size, below 12-edo in the "meantone temperament" the diatonic half step is larger than the chromatic, and above 12-edo the roles are reversed. This keyboard is different than most instruments in that it uses a tuning other than 12-edo, which is the standard tuning for western music.

Now that I've spent the last while looking into it i am thoroughly interested in playing with microtonality and just intonation. It is extremely interesting and makes me wonder why I have never heard about it until now. :( I don't have enough money for one of these yet, but perhaps you know of and could point me towards such a thing as an online microtonal keyboard to begin to accustom my ear to all these new sounds. Or will I just have to wait until I can save up some more money?

[DrizzitDudden02]

This kind of blows my mind and really interests me. I didn't understand that at the end though about how the the chromatic steps are wider than the diatonic. Is that just unique to this keyboard, or is that something that we would find no matter what the instrument. Forgive my ignorance, I'm just discovering a love for music and acoustics, so it's all pretty new.
