This is something I've been thinking about the last 3-4 years and desperately what I am trying to do. I have what I think some interesting ideas and implementations, but no one quite grasps my thought process and I am stuck between believing Im onto something and that I am furiously chasing nothing.

My experience in pursuing this is that I applied to about a dozen on-campus CS grad programs, over the course of two years, noting this research direction, but those applications were all rejected. You would think with the emergence of generative AI that there could be some interest. I suspect the application was of interest, but that universities have a shortage of experts in generative AI, and that a multidisciplin…

Oh wow thats nuts. Did you end up attending grad school for something else? Ive been thinking about applying but I haven't even able to find any departments that do research in this area. There is a huge craze around ML as its producing tangible results and it seems the school of thought is that anything else is wasted time.

The closest thing Ive found to my own is Wolframs writings.

Seriously I know I seem like a delusional nut but this train of thought has really grabbed me. Ive written hundreds of pages of (mostly intelligible) notes/figures and spend countless nights trying to implement what I can so clearly see in my head.

Unfortunately I dont have anything concrete yet that would warrant building a team, and its hard to even find people I can discuss my ideas with.

I think there ought to be interest in this area in mathematics, philosophy or even linguists though.

A real piano is also profoundly lacking in expressive control over timbre (excluding extended techniques like half-pedaling or directly touching the strings that hardly ever show up in the repertoire). The only control the piano gives you over note timbre is how hard you press the key. Once you've done that, the hammer disconnects from the key and flies through the air out of your control. A keyboard with polyphonic…

> The only control the piano gives you over note timbre is how hard you press the key. This is just not true at all. The action of a piano is a very sophisticated mechanism that conveys both acceleration and velocity, along with the initial position of the key (e.g. fully released or half-pressed). This allows for a huge amount of tonal variation, though it's more subtle than a ribbon controller, and obviously a synt…

>This is just not true at all.

It's entirely true for the attack, because of the escapement mechanism. At the point at which the hammer makes contact with the string, the hammer is mechanically disconnected from the key and moving purely through inertia. Once you've tripped the escapement, the hammer is beyond your control and pure physics takes over; the only variable is the velocity of the hammer when the escapement is tripped.

The release phase is controlled by a single parameter, albeit one that can vary over time. The key is holding up the damper, which returns to the string under gravity. A continuous value representing the range of motion of the key would be sufficient to model this with absolute accuracy. Digital pianos invariably sense release velocity rather than key position, because it's much cheaper to implement and is perfectly sufficient in virtually all cases; the range of motion between partial and full damping is so limited as to provide only a very limited degree of expressive control.

> "Timbre’s role in music has always been underrated, or even ignored, probably because it is an intangible that’s difficult to describe, hard to categorize, and so far, immune to measurement. " In the mid-to-late 1800s, Herman Helmholtz was building spectrographs of musical sounds by listening to them through a bunch of resonators of varying sizes that acted as band-pass filters, and recording how loud each harmonic…

The quoted section of the article is pretty out of touch with modern music. Many (most?) genres of EDM place the importance of timbre and texture above harmony and melody

"Terroir" is a terrible way to metaphorize timbre. The only similarity is that they're both hard to describe. Terroir is there before the wine is made and can't really be controlled by the winemaker (except insofar as they choose where to plant or what grapes to blend). Timbre is absolutely under the control of the musician.

Thanks, that analogy bugged me a lot and I couldn't get why a farmable region was similar to a variable sound envelope.

A terroir is totally describable, as by definition you have uniform geological and climatic properties (on the other hand if it can't be delimited it's not a terroir)

The way a sound evolves in time contains a lot of timbrical information. Different harmonics have different ADSR curves (Attack, Decay, Sustain, Release). Above all, one cannot overstress the importance of the attack transient. There are famous experiments in psychoacoustics that show that, when deprived of their attack transient, the sounds of two different instruments may become hard to tell apart. Personal anecdot…

> when deprived of their attack transient, the sounds of two different instruments may become hard to tell apart A neat trick is playing guitar through a volume pedal. You mute the sound, pluck a string and then swell in the volume pedal. The rest of the ASDR envelope can be created with other effects like delays.

The song Cathedral by Van Halen is a particularly brilliant example of this. Except even more remarkable he used the knob on the guitar to do it rather than a pedal:

This is tangential to much of what this article discusses, but I've had this idea kicking around in my head for a while, that, to some degree, the artificial imitation of acoustic instruments using synthesizers is to music what skeuomorphism is to design, and I (generally) dislike it for all the same reasons. This isn't to diss synthesizers on the whole - I unequivocally love them, and they really opened up my musical world by a wide margin. Nor am I saying that there is no place for synth patches that attempt to "sound like" "real" instruments (for lack of a better word; I consider every "model" of synthesizer to be its own very real and distinct instrument).

Skeuomorphic design, to me, largely feels lazy and unattractive; rather than designing for the new, maybe unfamiliar, medium you're working in, you attempt some facsimile which inevitably cannot live up to the original, either out of lack of ambition, or lack of faith in your audience to understand or appreciate without the anchor of a common metaphor. It lacks idiomaticity - there are particular details, quirks, associated with different mediums that lend themselves to different sorts of designs, and a skeuomorphic design language ignores these. (The same is true of musical instruments. A piece written for the lute, say, played on piano, would feel very different than a piece written for piano, played on piano; what is easy, or possible, on one instrument, is not necessarily as sonorous on another.)

To me, the use of synthesizers to emulate acoustic instruments, where the express intent of the composer/producer/whatever is to evoke the sound of that acoustic original (read: where the creator would prefer the sound of the real instrument), is, at its most generous, telling of a lack of creativity and at worst laziness. (If what you want is expressly the sound of a synthetic imitation for the purposes of your art, none of this applies.) It is a lack of creativity in the case where the creator simply does not have access to "real" instruments they'd rather use, and it's laziness where you have access and ability but opt for something you yourself deem inferior.

Of course, this all presupposes that there is something lost when say, a synthesizer plays a violin patch in an earnest effort by the creator to emulate a violin - where a real violin is actually what's desired. I think this isn't controversial to say, but of course it's a spectrum; I have much less of a problem in cases where the delta is smaller; e.g., simple legato harmonies from a string section can be emulated more convincingly (by orders of magnitude) than some virtuosic cadenza by a solo instrumentalist.

The lead developer of Melodyne, Peter Neubäcker, has one of the most precise and concrete understandings of timbre. He used that knowledge to create software which changes pitch without changing speed or timbre.

There's a neat documentary floating around which includes some scenes where he explains how he increased his understanding of waveforms in the frequency domain by physcially modeling them in the time domain.

"everything is possible" except for a synthesized instrument that actually has the expressive range of a real violin or saxophone. Even a synthesized piano is noticeably lifeless compared to the real thing (synthesized piano bass notes are especially thin).

It depends on what synth you're using, and how you're controlling it. Most synthesizers and controllers are profoundly lacking in expressive control, and of course a synthesizer that just plays back a recorded sample of a real piano isn't going to sound as good as being in a room with the real thing. Just because the mainstream synthesizer world has been sort of stuck in a rut for 40 years doesn't mean this is the be…

I don't have a good analytical response to this. Your comment doesn't pass the smell test for the following reason: I am a fairly serious jazz guitarist, and it seems to me like most great guitarists can be quickly identified by ear after playing three notes: Charlie Christian, Joe Pass, Blind Willie Johnson, Mary Halvorson, Django Reinhardt, etc. In some cases just one note is enough: B.B. King, Wes Montgomery, T-Bone Walker, Jimi Hendrix. (60 years later and still nobody plays octaves as well as Wes did).

Obviously some of their sound is tied to specific guitar models, but their tone is still easily identified on other guitars. And although these players were creative improvisers, that's not what I mean. Simply put: if it's a great guitarist, you can hear their hands like you can hear a singer's mouth. (Though hands are clumsy compared to mouths, and guitars are clumsy compared to horns.)

I am not anti-synth or anti-electronic music. But I do not believe any existing synth controller provides the expressive possibilities of an electric guitar, even Allan Holdsworth's goofy breath controller. Maybe I'm wrong and there's a great example out there on YouTube. But it seems to me that for an individual to express their individuality with a synth, they need to play a longer musical fragment and color their expression with timing, volume, vibrato, etc. Three notes "with pizazz" will not really be enough.
