Any plans to sell pre made kits of this? I'd love to get my girlfriend something like this but I don't have a 3d printer.


Hey congratulations!


Thank you!


Most of the time this is referred to as a MAP agreement and companies can be real aggressive in enforcing them.


Those same relationships are apparent when reading a traditional score. Once you reach a certain level of proficiency reading music it's easy to spot the intervals which make up a chord as written. I don't think the same amount of proficiency isn't needed to interpret a piano roll, it's just proficiency in seeing the same relationships notated differently.

All that to say I think they're both conveying similar pitch information and take a similar amount of effort to ready correctly. Piano roll doesn't convey rhythmic information and that's where I think piano roll falls short as a method of straight notation.


Imagine you are composing a piece of music that will move through a series of key changes (as most pieces of music do). On a piano roll you can see exactly which semitones are shared in common by the different major and minor keys. You can map your way through the transitions visually. A major triad uses 4 and 7 semitone gap, a minor triad uses 3 and 7. It's all so much simpler and clearer if you are starting from scratch.

Traditional notations are obsessed with pretending there are only 7 notes when there are in fact 12. Accidentals and key changes are obfuscated.


How are accidentals obfuscated on a traditional score? They are explicitly marked. It's on a piano roll that they would be easy to miss -- they appear the same as any other note.

Similarly, key changes are explicit in sheet music but hard to see on a piano roll without careful inspection.


What's obfuscated is the _actual_ semitone interval between the accidental and the other notes around it. And the actual semitone interval is the most important bit of information - it's what our ears hear.


I think what you're missing is that a big part of the design of traditional music notation is that it is intended to be read easily and efficiently, even sight-read. The musician reading the score knows the intervals that apply in the given key, down to muscle memory. The fact that a note lies outside the key is important, and that is why an accidental is marked explicitly.

Likewise, when a musician sees a run of adjacent notes without accidentals, they immediately know what to play. They don't need to inspect each one in turn to determine how many semitones it lies from the previous note. Likewise, when a composer wants to write such a run, they can just draw some black dots in a row. They don't need to squint at a grid and select the correct rows each time.

To sum up, traditional notation is uses a form of compression that makes reading and writing diatonic music easier.

Taking this even farther, some systems of music notation compress things even further and don't explicitly list all of the notes to be played. For example: figured bass, basso continuo, or even just chords that accompany lyrics. In fact, even regular sheet music doesn't usually precisely represent of duration of all of the notes. Some notes are sustained and bleed into others, some are meant to be played strictly in time. Human interpretation is an important part of the process.

On the other hand, the piano roll is a MIDI editor. It is a great way to tell a computer exactly what to play, but it is not easy to read quickly and it is impractical to print or write by hand. Both forms of notation have advantages and disadvantages but it seems to me you haven't spent enough time with the standard notation to fully appreciate its advantages. In other words, the piano roll notation might be your blub language for music. [1]

Fine. But I'm saying if you want to actually understand how music works (rather than play an instrument) the standard notation IMHO actually gets in the way.

Because the most important thing is the actual semitone intervals, and the standard notation hides them and gives them weird names like augmented fourth (it's just six semitones, just call it that). And it names the 12 semitones based on the c major mode even though that's only one of about 50 modes/scales/keys you might want to use.


This is great stuff. Accurate, succinct, well thought out. Nice job.


The Rosenfeld stuff is weird, man.


What is stopping someone from running signal on a dedicated burner if they're worried about it?

Different people have different threat models and I think asking for a phone number for the reasons posted above is acceptable for most people.


There really is no such thing as a dedicated burner. you don't even need NSA level threat vectors for most phone sim purchases in western countries to exfiltrate tons of user data.

Wifi is even worse, not better..


I think the best way to get a burner account is to use the free services to receive text messages online. These are enough to create an account, and you can then set a pin to prevent any takeover, assuming you synchronize your account every week.


With all of the controversy (real or imagined) surrounding the recent elections I think the company who makes the voting machines having an open exploit like this is a bad look.

No one is saying they were hacked this way but it definitely can be used as fodder to bolster election fraud claims (real or imagined.)


I went and did a season at mcmurdo in 2011. Its an amazing place and anyone with any amount of adventuring in them should make an effort to go work a season. It's life changing.


How does one begin looking for a way to do that?



The idea is that the amateur bands are a commons of sorts for everyone to use and enjoy. As somebody else said you're perfectly welcome to transmit encoded messages on nets designed for that.
