[@tombruges1557]

I think ignoring the chromatic notes closes so so so many possibilities. It means your harmony will always have its centre at the major scale. At least using the chromatic scale opens you up to most global music.

[@dolomuse]

The Lumatone can also render many varieties of minor, dominant and other scales. A good way to think about it is that, because the Lumatone accommodates a closer approximation to the pitch continuum, many more types of scales - Western/chromatic and other cultural scales - can be played on this keyboard.

I’d love to connect this to a eurorack modular synth. Please do what you can to encourage them include some kind of CV out as well. Having a dedicated CV out for eurorack modulars would be extremely helpful because most of us don’t use standard 12 keyboards anyway. We mostly rely on the onboard 16 step sequencer. Some of us don’t even use a DAW. Also transparent labels to manually assign root/octive, 3rd, 5th, 7th, (9th), 11th and 13th harmonic overtones would be nice. You wouldn’t even need symbols for the overtones, just assign them by number value. FAR OUT INTERFACE! It effortlessly incorporates theory without any translation. I think it’s very intuitive based on your demo.

[@goingmodular]

This is very interesting. Let us not forget however that musical "interfaces" with continuous pitch (besides the human voice, obviously) have existed for eras under the form of fretless string instruments. That natural notion of continuity has been integrated for long into both North-African and Classical Indian music traditions, to name only two examples. In 2023, we definitely need both modern keybeds able to allow full access to that larger spectrum, and also a proper, unified notation system that gets away from the classical microtonal "accident" syste ( which is way too referential towards the diatonic tradition). Such explorations as this instrument here and your music are great steps in that direction.

[@AlbySilly]

I haven't seen a video from this channel for a really long time

[@mr88cet]

Two things strike me as intriguing here. I’m not suggesting that these are “bad” choices, by any means; just “curious” ones. You’re making intriguing music, and that’s all that ultimately matters, so “keep it coming”! First, it’s interesting that it appears at least (9:30) that you’re not mapping an upward whole step to the key directly to the right (and slightly above). Instead, you appear to be mapping it to the key directly above that. Again, not necessarily good or bad, but interesting. Second, 55TET strikes me as a … curious … choice. To whatever degree it’s about approximations to small harmonic ratios (2:1, 3:2, 5:4, 7:4, etc.), 41TET and 53TET get a lot closer. Of course, Just-Intonation approximations are just one dimension of the question. They’re not necessarily a goal, but are a factor.

[@macronencer]

It seems a little odd that each column has 8 keys, except the B columns, which have 7. Why is that? Is it related to the limitation on the number of different notes in MIDI? Also, I would have thought an odd number would be better anyway, so that there is always a central key. It's an amazing controller though! Did Elaine Walker have anything to do with it? I know she has advocated in the past for hex keyboards that light up and can be configured to arbitrary patterns.

[@sorcerydiamonds]

[@modalmixture]

I really appreciate your methodical approach to exploring this instrument - looking forward to some inspiring new music! I know you like the focus to be on the harmonic interactions, but I wonder if you’ve thought about mapping the polychromatic dimension to other parameters besides pitch to create variations in timbre as well?

[@dolomuse]

That is an amazing area to explore! I guess at this point, I'm still trying to work out and explore the possibilities of polychromatic keyboard technique and an adaptable system for notation and learning. The Lumatone's keys are continuous controllers and as new features are implementaed in future firmware updates (and MIDI 2.0), we might be able to assign an overlay of CC messages to each key as well (i.e. modulation, filter sweep). With MIDI (1.0), I have run into 'buffer overload' type problems with using 16 channels of CC (pitchbend) messages simultaneously. Very exciting possibilities ahead!

[@goingmodular]

I have a general interest in the way "new" controllers integrate the possibility of microtonality. This Lumatone instrument is definitely exciting and also extremely pleasing on the visual side (which, I find, is also a meaningful characteristics of musical instruments beyond the mere cosmetics). It raises a few questions or issues however, and maybe somebody here has clues about them. 1. Why choose a hexagonal structure ? Why not a cartesian (x,y) rectangular grid ? I fail to see the meaning of the intermediate directions, or rather, it seems to me that there is a lack of symmetry between some of the hexagonal directions (like right ascending vs left ascending for instance). Any idea what the creators had in mind with this kind of layout ? 2. One difficulty I see both playing and "reading" the keyboard is that contiguous notes (in the sense of pitch) end up being very far from one another sometime (like, the red value of each classical chromatic note is tonally contiguous to the purple value of the next one, and yet the two corresponding keys are as far apart as they can be). Maybe it would make sense to extend the colour spectrum up and down (at the cost of redundant notes) to keep some degree of microtonal continuity when needed Just my two cents/interrogations on the system. This is all very interesting anyway.

[@driver1140dg]

Why isn't there a B####? Sorry if I missed that explanation I love that you spent time talking about notation from a human factors standpoint :)

[@dolomuse]

Great observation! The Lumatone designers created a 275 hexagonal keyboard and this created an asymmetry in one column (the 'B' column has one less key). I just adapted to this by dividing the octave into 55 pitches, but the color layout reveals the missing key. The polychromatic system is flexible enough to work with unique keyboard designs like this.

[@dareen93mt98]

Hello Dolores, thank you for your work. Do you know any weighted keys microtonal keyboards?

[@dolomuse]

The Lumatone has a lever-action for each key. All the other microtonal keyboards I know of have electronic switches/pads (minimal movement/excursion of the key, or a pressure sensor). The Lumatone's lever-action gives a piano-like movement to the key, but it is non-weighted. You may want to check out Elaine Walker's keyboards, she makes microtonal 'vertical' keyboards, but I'm not sure if they have weighted key action.

[@dareen93mt98]

@@dolomuse Thank you for your answer. Which ones you know have pression sensors? I'm looking for a microtonal keyboard suitable for performance which will allow me to play as many as sounds as possible but will not neglect dynamics. I find switches not convenient enough as I'm often losing in fluidity while using them. Elaine Walker's keyboards don't seem to allow any change in dynamics, I don't think they have weighted key action.

[@camtaylormusic]

Fantastic video Dolores. I have several questions about why you chose the layout you did, but I think I know some of the answers. I was one of the backers for the Terpstra campaign back in 2013, so good to see this keyboard is finally (almost) ready for the world, and so excited to get my hands on one this year! I am actually writing a book about generalised hexagonal keyboard layouts, using the Lumatone to display coloured shapes and layouts on, and writing about exploring microtonal intervals, scales and chords in a generalised (key agnostic) manner. I see that although you have your natural row as usual in a single chain of fifths from F-B, with the 12:30 (almost horizontal) axis mapped to the major second, 196c in 55EDO, and the 2:30 (down-right) axis mapped to the minor second, 109c in 55EDO, across the central (white) natural row. I can understand your wanting to get rid of "black" key pentatonic sets, although I find they are incredibly useful in helping you find your way around without thinking or working anything out, with sharps above and flats below the central natural row, and they help transfer knowledge across keyboard instruments, as well as incorporating standard music theory, across many tunings. One of the problems I see with your layout of using a single degree vertically (where the sharp would normally sit, we instead have 1\55=22c), is that the isomorphic nature of the keyboard is broken, and so you need very slightly different shapes for different keys, as I can see with your "major" (actually a little supermajor) scales on white C (C natural) and red A (one degree above Ab). Another problem I can see is that while you get a few doubled keys (blue E, two keys above white E = red F, three keys below white F = 20\55 = 436c above C, indigo E = orange F = 21\55 = 458c above C, violet E = yellow F = 22\55 = 480c above C, ditto indigo B = orange C, etc), you actually lose 5 pitches per octave, the regular flats Db Eb, Gb Ab and Bb in 55EDO, which I believe are pretty important for performing a lot of music. My solution that also incorporates colour is to maintain both heptatonic (natural) and pentatonic (sharp/flat) groups, but to colour each differently. I have managed to colour most EDOs featuring a fifth in the range [686c, 720] up through about 60, plus a few other higher EDOs I really like, and I would love to hear your ideas on that too, though I can understand wanting to get rid of "black key" groups. I believe there might also be a better solution for you that gets rid of those groups but also lets you keep the isomorphicism which is one of the generalised keyboard's strong features, and allows you more freedom with less thinking and counting of keys. Amazing of course that you've gained the virtuosity you have in such a short time, and fantastic explanations otherwise. Would love to connect either here or over on Facebook. Thanks, and love your work. Cam

[@camtaylormusic]

Also, I do think that even though this controller has 55 keys per octave, you would probably find 46EDO, 53EDO or 58EDO would suit your purposes better than 55, which is a meantone tuning without the excellent approximations to higher harmonics and interval regions I often hear in your other work. Sure the approximations are close, but I think the general intonational bent leans the other way, and you'd really love the virtually pure (2:3) or slightly (1-3c) sharp fifths of those systems better than the mellow flat fifths of meantone. I know you know 106EDO well so I imagined you would be playing in 53EDO here, but 55 surprised me. Cool to see nonetheless, and the approximations are close enough not to disturb your soundworld too much, but I think the tuning system should go even further in enhancing that soundworld! Best, Cam

[@dolomuse]

@Cam Taylor Thanks Cam, it would be great to hear more about your approach! My approach is more practical than theoretical in the sense that I want to explore the maximum pitch-resolution ergonomically possible on any keyboard design. I think of the natural state of pitch as being a continuum, so any method of pitch division is a “temperament”, based on one of many possible numerical perspectives. Because the many methods for creating micro-pitch scales are so complex in their musical possibilities, I keep things basic in this area by using equal divisions of the octave as a framework. Isomorphism is an interesting area. I appreciate the polymorphism of the piano, especially in the way that each scale/chord/arpeggio feels and looks different. Because of this, you can play by the feel of these patterns without having to look at which key you are in. The guitar/bass has an isomorphic quality to it, but it also has multiple position patterns which are different-and yet the same for each key. Isomorphism is definitely a great technical perspective… I guess the best analogy I can think of at the moment is the steepness of the the ‘learning curve’. 55 EDO was just the limitation of the Lumatone key layout. I enjoy exploring the way the pitch-colors and micro-intervals interact in these large pitch sets. I just look at it as blending colors like a painter, hearing the interactions of sound and space, and am not very oriented in the numerical relationships involved.

[@camtaylormusic]

Thanks so much Dolores for your detailed reply. I totally see where you are coming from, and things like getting the maximum resolution, keeping a unique shape and feeling for each key seem at first to fit with your musical goals, however considering how much time it often takes a musician to master 12 keys as well as they have learnt 1 or 2, cutting the time taken to really master 55 keys with different shapes and "feel" under the hand is really going to come in handy for most people. For me, I feel the different look and the same shape goes a long way, so one uses the isomorphic nature of the keyboard mapping and the multicolour layout to see the key relationships and the sets of (in my case 7+5, in your case 7) similar coloured keys per octave to guide the way, more than memorising the shape and feeling of individual scales. While I like the idea of equal divisions of the pitch space, and using all varieties of intervals equally, every division has certain biases, and while I think 53 (106) and 72 suit your aesthetic they also provide fantastic approximations of the lower primes that I think make the biggest impact on your musical sound, 2, 3, 5 and 7, but also opening the doors for good approximations of higher primes too. Under many metrics, 55 doesn't do nearly so we'll, and also its melodic step sizes are not quite so appealing as those in or close to Pythagorean intonation. When I get my hands on my own Lumatone I'd love to try to convince you that 46 or 53-equal (in a fully isomorphic fashion), or 58-equal (as two separate isomorphic rings of 29-equal, itself a closed chain of fifths, and so moving between the rings breaks isomorphism) would serve you even better than 55 on the Lumatone. Even though I don't have an instrument big enough, my favourite equal division of the octave is probably into 94 parts, and that is not because of simply maximum resolution, but also the consistency of all ratios up to the 23-odd-limit (primes very well tuned up to 23), and how their approximations are inter-related. While 55edo for me is chiefly ruled by its meantone temperament (suggested by Mozart's father as a sort of master tuning with each whole tone divided into seven parts, and the difference between a standard C# and Db a single part or comma) and its division into 5 parts (equal pentatonic 0-240-480-720-960-1200c), 94edo tempers out the schisma so that the most sonorous 4:5 major thirds are mapped on the keyboard as diminished fourths (-8 fifths), but the fifths are just very slightly sharp of a just 2:3, so super sonorous, great Pythagorean diatonic intonation, plus the syntonic, Pythagorean and septimal commas are all equated, as they are in 41 and 53-equal. Plus the sizes of seconds and thirds for example just all feel musically useful for me, while some of the sizes in 55 for example don't feel quite right, even if you're not using any kind of JI, rational, or concordance reference. Hard to say exactly what I mean without the keyboard in front of me.

[@dolomuse]

@@camtaylormusic That sounds amazing Cam! I'm looking forward to hearing and seeing your pitch layout implementations on the Lumatone. It is groundbreaking that the Lumatone can accommodate so many layout methods. They are planning on establishing a library of iso/polymorphic presets as users develop them. I hope the simplicity of the polychromatic system will replace the complexity of microtonal notation symbology/terminology, so we can focus our time on implementing any conceivable scale method (pitch palette) and quickly focus on creating/performing new micropitch music!

[@organist1982]

@@camtaylormusic Do you have any idea why the Lumatone is designed with (only) 55 keys in the repeating geometry instead of, say, 72, with more vertical rows like the MicroZone?

[@oscarallen8484]

how would you compare this to a LinnStrument programmed to have a similar pitch layout?

[@dolomuse]

They are both great controllers, but quite different in specs and design. The LinnStrument has square shaped silicone keypads (multidimensional sensors). They are color-programmable and can render MIDI data in the X (left/right), Y (front/back), and Z (pressure) dimension. The keypads have no movement with playing. It is an amazing instrument with open-source firmware. The LinnStrument has 128 or 200 color/tuning assignable keypads. The Lumatone has lever-action, color assignable plastic hex keys, so there is motion of the key when played. Each key has a Hall-effect sensor (like the Continuum), so it can, with firmware updates, render precise position and pressure data (Z dimension). No X or Y data can be rendered with the keys on the Lumatone, but you have more keys to assign pitch values to. The Lumatone has 275 LED color/tuning assignable keys and an editor for programming.

[@ashtonlyons2139]

You don’t need black or white keys to play the lumatone, but you need color-vision. And how are blind musicians supposed to find where they are on the instrument without the tactile land marks offered on the piano/ keyboard?

[@dolomuse]

I'm also going to try using braille stickers for tactile orientation. This could be helpful in navigating the keyboard for sight reading, and also as an orientation for visually impaired musicians.

[@BenGreen1980]

Are the chromatic sharps and flats you'd find on a traditional keyboard on the default Lumatone configuration?

[@Retro6502]

I'm a little confused by the description around 3:43. You mentioned removing removing black keys from a piano and adding pitch colors above and below, which makes sense. But then the overlay graphic shows A B C D E F G next to each other with colors above and below them. As B->C and E->F are only semitones apart, wouldn't that lead to overlap (duplicated keys) between those pitches since it seems there are the same number of keys between each note / pitch class?

[@dolomuse]

I think it’s easier to think about it as an octave being divided into 55 pitches. The pitches are then assigned according to the physical layout of the Lumatone keyboard. The modal reference of A-G is only used as a known point of reference and departure - A-G aren’t related to each other in the same way as in the chromatic scale (i.e. E/F and B/C semitones). Instead, the white row notes are similar but not exactly the same as the white notes on the piano. 55 EDO 12 EDO A = 55/55 [1] A = 12/12 [1] B = 8/55 B = 2/12 C = 15/55 C = 3/12 D = 23/55 D = 5/12 E = 31/55 E = 7/12 F = 39/55 F = 8/12 G = 47/55 G = 10/12

[@Retro6502]

​@@dolomuse Thanks so much for the reply, that helps a lot. You're right, it is easier to think of that way and makes a lot of sense. My thinking that the white keys on the Lumatome lined up with the white keys on a piano threw me off. I also understand now why the note names on the graphics moved later in the video (8:55) - you were showing patterns/shapes with the intervals of a major scale, for example C-white, D-green, E-cyan, F-yellow, G-white, A-green, B-cyan, C-white. Thinking of it as shapes like guitar chords makes a lot of sense for shifting scales up and down through the pitch colors. It's an amazing instrument, I'd definitely like to try one. Thanks again for demoing it and for the explanation.

[@dolomuse]

If they get enough sales in this first production run to stay in business, they will be working toward producing a 'mini' model. This has been the greatest difficulty with innovative musical instruments: they are very expensive in the prototype stage (recouping R&D costs). But if they don't recoup those costs they can't develop more products which are smaller, cheaper and mass produced. Roli is a great example of this.

The polychromatic stuff is beyond my imagination (in a good way), but the electronic voice is quite disturbing to my ear. Can you use other kinds of samples in your incredible videos/compositions too? (Like maybe a microtonal piano sample?)

[@vizangrando]

My guess is she uses this sound to enhance the harmonics of the notes, but I´d really like to see what kind of sounds could be achieved with softer tones.

[@oldnikix]

Brass or rather saw waves disturb You? That is a Richard Wagner effect... Did The Flying Dutchman play in the background of a traumatic event? Half joking, of course. I thought she should have used Sine waves... So pure and calming.

[@vizangrando]

@@oldnikix Agreed, i was guessing she used saw waves in this video, for fuller harmonic content maybe. But if you check her channel there are some videos where she uses a softer tone :)

[@KnzoVortex]

@@oldnikix Harmonically rich sounds tend to give you a better idea of the sound of each interval, your brain notices how each harmonic of each note interacts.

[@oldnikix]

K nzo [Vortex1212] True enough for normies. I'm fairly certain if you are into polychromatic, microtonality, and the like, your ears can perceive sine waves' frequencies adequately. I know, it's a KZbin crash course. Don't worry, be happy 🙏🏻

ableton live's max for live community might be really helpful in terms of microtonal midi devices

[@phlubblebubble]

Completely off topic -- but I'm going through your uploads and noticed the "Moose tipping" shirt in your previous video and the snow covered spruce forest (in May) in this one. Are you in Alaska or the Yukon?

[@tonywatson8959]

With your configuration, did you choose to omit B violet deliberately? Or was it simply a limitation of the prototype? A combination of both? Or is B violet actually sitting there in plain sight and i missed it? Thanks!

The Lumatone keyboard was designed with 275 instead of 280 keys and this left an asymmetry in the "B" column. My adaptation was to divide the octave into 55 EDO and workaround the 'missing' key.

While this keyboard is designed to be able to accommodate a myriad of layouts/mappings, in looking at the overall geometry of it and comparing it to your MicroZone, I get the impression that it's primarily designed with the primary MicroZone-type layout in mind but with fewer keys vertically and more keys horizontally, which would still be 55 EDO here; would you say that's the case? If the normal 7+5 chromatic layout of the MicroZone were applied to the LumaTone, I can see that the columns for the naturals would have 5 keys each, and the columns for the sharps/flats would have 4 keys each. Also, is it your hope that LumaTone would eventually come out with a model that has even more keys, particularly in the vertical direction, so that you could apply your layout here to a higher EDO, say, 72 EDO?

[@dolomuse]

Very cool ideas! This design opens seemingly endless possibilities to explore. The keyboard could also be split and programmed with multiple tunings and varieties of iso/polymorphic colorized layouts! The analogy for me is a painter’s selection of palette colors to mix in a work and also in the sense that different color palettes can be easily chosen for different works. The polychromatic system is an attempt to create a simple framework with flexible assignments of pitch-color relative to the tuning method, with a consistent in a spectral-type ordering from (infra/flat)red to (ultra/sharp)violet. This makes transitions to different pitch-palettes easier for musicians and dovetails well with standard music notation. The Lumatone is based on a modified Terpstra design (circa 1980’s) which is, to my eyes, a variant of the Wilson layout (circa 1970’s) with the added innovation of a cascade key design (hex keys gradually ascend in height from front to back). The Lumatone design has further implemented led color, note# and channel# assignment, velocity sensitivity and has capability for firmware additions like aftertouch implementation, as its keys can also render continuous control (MIDI CC) messages.

[@davestarns]

Is there a specific pattern of colors that would indicate the pitches corresponding to "just" intonation, or does this particular microtonal tuning include those exact frequencies?

[@ValkyRiver]

I posted about color notation for just intonation in my channel.

[@Planthier76]

Hi Dolores, Simple question : is not a bit illogical to have unequal number of keys inside each column ? Nice video ;)

[@organist1982]

I had to watch this and do some thinking before it occurred to me that the keys of the same color are dividing the octave into 7 equal intervals, or the 7th root of 2. Edit: I realize that the interval between keys of the same color must be very slightly wider than the 7th root of 2 since one "column" in each octave has one fewer key than the other "columns." At any rate, it seems like that would really take some getting used to!
