I play the lumatone ( https://www.lumatone.io/ ) which is very similar. I personally love it, especially as I like to do a lot of improv in various tunings, and the layout makes transposing and thinking about structure so much easier than a traditional keyboard. The terpstra seems similar, not sure what their selling point is over the lumatone. Edit: oh, it seems that the lumatone is the commercialized version essent…

Any idea why something like this costs $5,000? It seems like manufacturing costs would justify 1/10th of that maybe? Disclaimer: I'm not a hardware manufacturer nor retailer, I'm just going off what regular typing keyboards go for.

For folks wondering wtf is going on with the key layout, this is what's called an isomorphic ("same shape") layout. The idea is you can learn how to play a certain grouping of notes relative to each other, and then you can play that same grouping anywhere on the keyboard relative to some other note. So for example a C major triad is the notes C-E-G played together. And a D major triad is the notes D-F#-A played toget…

Not only the bass buttons, there is a type of chromatic button accordion, popular in eastern europe.

Now piano players will be able to join guitar players as not needing to read music or know theory!

Are there any regular typing keyboards with velocity sensitive keys? I genuinely don't know, it's just the first thing I'd compare this to

And then there are diatonic accordions, which all use a similar layout both for the bass and melody sides (but you can't play in all keys[0] on them, that's the difference between chromatic and diatonic). While they are simpler than chromatic accordions, they are now usually more expensive because fewer people play them.

[0] that is, ~"scales"; usually all buttons will be working

Yeah, velocity definitely jumped out at me as a difference, but it seems(?) like being velocity-sensitive could 2x the cost, maybe even 3x, but not 10x ¯\_(ツ)_/¯

I'm absolutely not calling it over-priced, just puzzled.
