   The claim is wrong, I didn't know about the rsync compression (-z option, wish it was defaulted). I ran a test using the rsync compression and rsync transferred a little bit faster (~4% faster). croc is faster than wormhole last coupl

   > "croc send -c 'xyz blahblahblah' filename" on multiple computers without error That seemed to be a bug and is fixed now. After two parties enter a channel it should give you a "room is full" response. >

   The receiver and sender find each other using the first three characters of the passphrase to establish a channel to communicate. Once in the channel they perform PAKE which will allow both parties to establish a secure key from the entire

   When I measured jitter I found that it was higher in cheaper instruments [1], so I think it might be dependent on the hardware that is listening to the MIDI output. [1]: https://github.com/schollz/miti/issues/

   I would love to hook up multiple - the polymonotron...

   Thanks :) I play piano and I don't find the latency a problem, which means its probably < 100 ms. The midi stuff is actually just bindings to rtmidi (in C++). The most annoying thing is "jitter" which I calculated to be 15

   Thanks! That's a neat solution! If I had seen that before, I may not have made miti :) I found there's other few programming-friendly simple MIDI sequencers [1] but generally none of them were simple enough for me. I'm pretty

   Yeah, the monotron is monophonic. But you're ear is right on because it does sound like multiple synths - I'm actually augmenting the monotron a bit here using another device called the norns [1] with a script I wrote [2] which co

   Thanks for that link, wasn't aware. For this I used the simplest approach I could think of - using sox [1] with its builtin power spectrum analyzer. It works pretty well as the resulting tuning is fantastic. It would be nice to a faste

    I get that my solution is a little more expensive. But, actually the whole thing costs ~$25, not $40, if you buy the three components thriftly (used Pi ~$15, usb audio adapter $5, mcp4725 $5). In contrast, that link you mentioned has over 1

    As BusTrainBus says, "installability" is useful, and it was one of my motivations. I agree installation for magic wormhole is easy for Mac/Linux, but I think its not easy on Windows. Windows is very common (77% of the market

    Definitely possible. I'll happily take any PR that does this.

    I maintain it. Its been up for about 2 years with pretty minimal downtime. In any case, I encourage everyone to setup their own relay. Its easy. Make sure ports 9009-9014 are open and then run `croc relay`. Connecting to your relay is as ea

    I initiated the croc project. Others have asked me the same thing, so I'll bite: I chose not to copy the features of magic wormhole because it seemed to me (at the time) to be very complicated and lacking in features crucial to myself

    There's a big community of ambient/electronic musicians that are still using these things. They are popular for recording/playing tape loops and making tape delays. I bought some recently to convert into a makeshift mellotron

    I made a lot of music stuff. I hooked up an Arduino to control music tempo with my heart beat [1], made a browser based sequencer for the Korg NTS-1 [2], and a made a web app to generate patches for Teenage Engineering OP-1/OP-Z [3] [1

    Totally amazing. The work you did seems tortuous but its looks like its paid off! What a brilliant machine you have now, with so many possibilities, on top of sounding really really good.
