Thanks for the wonderful Lumatone series Dave. I gave up on trying to learn the keyboard some 50 years ago because of the incomprehensible jargon and illogical explanations. After seeing your series and reading about some of these new keyboards I now have a totally different perspective.
Always love seeing new vids from Dave and this one's no exception. It's great to hear all the different tunings and how they work. Also I absolutely love that shirt!
Thanks, Dave, for previewing the 22TET layout! My only experience with 22 has been on a guitar I refretted right after I went off to college. I promptly discovered that the best way to tune the open strings is in straight-up fourths: EADGCF, rather than EADGBE. The reason is the pseudo-comma you mentioned. The major scale reflects the Pythagorean 9:8 and Syntonic 10:9 whole steps. So the major scale, in scale degrees, goes 4 3 2 4 3 4 2, 4 degrees being a functionally equivalent of 9:8, and 3 being functionally equivalent of 10:9. The problem is that analogous with JI, for C-major you have 3 degrees from D to E, whereas in D-Major, you have four degrees from D to E, so which pitch is an E changes! However, if you tune it up consistently in fourths, you don’t have to answer the question of which G and B definitions apply in the particular key you’re playing in! A fourth is still always a fourth, no matter what key you’re in. I haven’t worked with 34TET on guitar in particular, but the awesome Microtonal guitarist Neil Haverstick, came to the same conclusion for 34TET. Fourths!
Another important consideration is that our current notation system is based on meantone, which makes sense since our modern notation system and meantone tunings both came into use at around the same time. Meantone tunings are tunings that narrow the fifth from the just ratio of 3/2 so that the syntonic comma of 81/80 is tempered out. This results in the 5th harmonics being simple while the 7th harmonic's intervals are complex. 22-EDO is the opposite: It is a Superpythagorean tuning, where the fifth is tuned _sharp_ of 3/2 to temper out the septimal comma of 64/63, resulting in the 7th harmonic's intervals being simple while the 5th harmonic's intervals are complex.

It's not just that, 22 TET has a sharp perfect fifth so if you stack fifths for normal intervals they become really sharp (the major third is more like a supermajor third like the video said), so the intervals just below sound closer to just intonation
What do I think about this instrument? I think it is is a great idea. I think is way ahead of time. It won’t be a super best seller but a few will be playing with it until they realize it can’t be used to make money at all (as a musician that make a living playing an instrument point of view) Just imagine just opening the box and try to create a beat for a client or even a melody for a movie, this is the type of tool you wish can save the day but at the end you just pick your old, dusty midi keyboard controller to get the job done. How much would you pay for this if you found it on a Goodwill Store? Be honest. (Not being a hater, just being realistic) many people will think “cool toy” right away (even that is not). I’ve share this vid to three music producers and my comment about this instrument is way humble and nicer than their opinion.
I have one and despite the fact that I have no intention of using it to make money, it's the best $4k I've ever spent on anything other than my degree in mathematics. The thing that perhaps isn't so obvious about it, but really should be a top selling point is that isomorphic keyboard layouts are dramatically easier to learn to play than the normal piano layout. For someone who wants to be able to make music, but doesn't have 8-10 hours a day to practice enough to get really good, the isomorphic keyboard layout is a huge force multiplier. Every scale, chord voicing, or other musical object you learn to play can be transposed just by moving your hands to a different part of the keyboard, so you don't have to e.g. learn Eb melodic minor scale separately from the C# melodic minor scale separately from the A melodic minor scale -- all melodic minor scales are the same shape and use the exact same muscle memory. Repeat ad infinitum for every other scale, arpeggio, lick, etc. etc. The fact that when you're playing in any key, you're effectively practising and building muscle memory for every key saves a tremendous amount of time. Depending on what kind of price tag is on your time, this can mean that the thing might pay for itself pretty quickly. The fact that isomorphic layouts also make it possible to comprehend other tuning systems is really kind of sugar on top by comparison. Don't get me wrong, it's a rabbit hole of new sounds and inspiration in itself, and a ton of fun, but if you're looking at this thing from a financial perspective, that's not what makes it so attractive.
@@cgibbard good points ! i bought it for the isomorphism, but it's almost a must for people into micro-tonality. it's not cheap, but you have 280 keys/buttons that are lighted, pressure/velocity sensitive, polyphonic aftertouch, etc... maybe a cheaper version could be made with features aimed at the people interested only in the isomorphism, if there is a market for that... i think there could be.
@@moontan91 wait, this thing is velocity sensitive and has polyphonic aftertouch?! I've been listening to performances by various people, and I came to the conclusion it's not pressure sensitive.
@@GizzyDillespee it is indeed and you can also customize the velocity curve. go check the specs on their website. it can do a lot more than that; each key can be assigned to a CC as well, there's also a feature called Lumatouch. they have other videos on this channel that goes into more details about those features.

Hell yeah
What vst are you using for the piano sound and whats the timbre?
I believe this was the Petrof piano from PIanoteq
Oh no, my long comment disappeared because it had a link in it... is there any chance you can rescue it?
probably not.
my advice would be to always use a text editor, then copy and paste into RUclips or anything internet, in case things go bad.
Could you make an octave wheel comparing 22edo notes with 12edo notes?
Or is that too tiresome to make for each new tuning you explore.
In my opinion, a lot of the notes that is just below the common ratio names just sound better, maybe I just prefer flat
