           | out musical noise) and didn't play music in time. In fact,
           | the video from the submission has had its audio significantly
           | edited to sound pleasing. I believe he posted the raw audio a
           | few months ago in a video. His current design looks much more

           | It's a bit of a touchy subject. It's clear that he's a
           | brilliant musician and self-motivated to the brink of mania,
           | but he struggles with perfectionism and his insistence on
           | reinventing the entire field of mechanical engineering from
           | scratch precludes him ever actually finishing the project to
           | his own impossible standards. If he didn't have a huge
           | community of experienced, fascinated, and often frustrated
           | engineers and manufacturers pointing out his most egregious
           | missteps, he'd be sunk. The past near-decade has involved
           | being sucked into fractal rabbit holes due to unknown-
           | unknowns while obsessing over imperceptible details. The
           | second machine was thrown out entirely and he started from
           | scratch in an attempt to fix what he saw as fundamental flaws
           | with it, and while his process with the third machine seemed
           | promising at first, at this point it doesn't seem like he's
           | really any closer to success.
           | 
           | His videos are often entertaining (he's very charismatic and
           | enthusiastic), and you'll learn a decent amount about
           | engineering. But the most important thing that you'll learn
           | are the unstated lessons: the necessity of compromise and the
           | importance of setting measurable and realistic goals if you
           | ever hope to actually achieve a given result. Though if
           | nothing else, I applaud him for being so open with his
           | efforts, especially when things don't pan out like he was
           | expecting.

             | I think in the last video or 2 he finally had the

             | it. We'll see if it holds up.

               | begun setting standards for himself that are necessary
               | for mission critical projects like space flight and
               | driving, but lost touch with why we are interested in his

               | goal.
               | 
               | The consequence of that is that it has to be reliable
               | enough to play through a full concert without maintenance
               | or breakdown, and it has to be robust enough that it can
               | be transported from place to place. These are his hard
               | requirements.
               | 
               | Then there are some less well defined requirements. Which
               | is that the machine has to play nice music and has to be
               | a marble machine as Martin understands it.
               | 
               | This last is the real constraint. Otherwise he could just
               | buy a midi keyboard which would fulfil all the
               | requirements about reliability, robustness and quality of
               | music, but would fail the spirit of the endeavour.

               | 
               | Yes, we want music that is sufficiently accurate and

               | The slight errors of both time and intonation in some
               | cases give music a much more human feel. Now to be fair,
               | I don't want to suggest that this sort of human
               | inaccuracy is mere randomness either: it's typically not

               | 
               | The cylinder has a certain speed and length, so music
               | must be written in a certain way that it fits there in a
               | pleasant way if looped. This means ending in a fermata,
               | sort of fading (and not truly looping) or having the
               | number of bars be somewhat musical (often powers of 2).
               | 
               | From knowing the tempo of the song and the speed of the
               | cylinder you know how many notes of a certain length you
               | can fill in one rotation: 8 full notes, 16 half notes, 32
               | quarter notes, and so on. [1] Just divide the
               | circumference by the numbers and you get the physical
               | length of each note. Keep in mind that if you're not
               | truly looping and is ending the song with each
               | revolution, you can be very fast and loose here.
               | 
               | So the written music itself, plus the physical lengths of
               | notes, will inform you on where you should place each
               | note.
               | 
               | For multiple pitches: pitches are just in a different
               | axis. One axis is timing, the other is pitch. This is
               | visible when you look at the "comb" of music boxes, they
               | have pitches arranged from low to high, side by side,
               | like harp strings or piano keys.
               | 
               | About syncing: it is all written in sheet music, so you
               | just follow it. Two notes that must be played together
               | are just on the same axis. For a more tight timing just
               | align it... It won't be perfect if you're a kid doing it
               | by hand, which is why music boxes traditionally often use
               | arpeggios in detriment of more blocky chords.
               | 
               | Multiple instruments: if a music box can play different
               | timbres, it's triggered by having duplication, meaning
               | two or more sound producers (combs, hammers + strings,
               | etc). So you have, for example, 20 notes available for
               | one instrument and 10 for another. But it is all on the

               | perfect anyway, and a lot of techniques and styles rely
               | on this (from drum flams to Dilla beats)
               | 
               | Not to mention that music boxes are mechanical, so it
               | won't be perfect during playback anyway.
