the guy talks on a bit, but when he gets to the part about: to just... think it... it's so hard to explain how it feels! and he's giddy like a little kid. i just kind of smiled, and thot: yeah, i know how hard that is to explain, too. when i first built out my modular to the point where it was, like, useful, i was sitting there, playing with it, utterly focused. i got into some complex finger configuration and closed my eyes in order to concentrate on the sound. my hands utterly still except moving some knobs in between my fingers. after a few minutes of this, it's like my hands had ceased to exist, and i merely thought changes in the sound. then my boyfriend tapped me on the shoulder, and it all popped like a bubble. dammit! kubla khan, have you heard of it, dan? no? ppf obviously i wanted this to happen again, and that's been a long journey, building a weasel megazord with robot arms. modular robot arms. it happens to me all the time, now. my hand will get settled into some comfortable nook and a few seconds later i don't have a hand anymore, just some parameters i can control with my mind. and, of course, arguably, i do still have a hand, and it's controlling the knobs physically. but it's so hard to explain how it feels |

Isn't it a bit extreme to cut off your own arm just for a music project! |

heck, i was actually just coming back to ask: yeah, i could play an 808 with muscle twitches, is there a thing? thanks. follow-up: has someone already sorted out how to get this into MIDI? you'd obviously need another arduino or something; form a hub of sorts for multiple sensors and then spit it out to a MIDI port. i cannot find anything on google. really, though, single-use ekg sensors; PITA. do i need the grainy jelly too? i actually explored this years ago as a computer interface, trigger the shift key or something. almost makes more sense for that, than for music ... 'cos, good as i'd be at multitrack twitching, i would probably still need to practice in multiple sessions before i can do it at the same time as running gear. and would be through the whole pack of medical sticker things before i really got going |

i actually build some prosthetics myself with an ecg sensor that i used as a myoelectric sensor, before you could get sensors like this easily you need an arduino, yes. i only used it as an interface for the sensor to get the data into my computer. you could program a midi controller on the arduino itself to have an autarkic device. i programmed everything on the computer i made a test were i played a snaredrum with my eye lid. worked perfectly |

how do you get ecg wired to your eyelid? i think i may get the dev kit. i don't have any hope for this to be practical for studio usage -- having to buy bags of sensor stickers, and heck! it's pretty bulky. even just one on my arm could be too cumbersome to really be worth it but i can think of some non-music uses for this. musically, i suppose my ideal want would be being able to send gate triggers using muscles in my toes and feet. there's a lot, down there. articulation, zones. and they're not doing much when i'm recording music seeing how this works, though, i'm not sure you could do that. everything's too close together and it would just be like trying to listen to six radio stations at once |

i was more inspired by psych classes... rubber hand illusion, phantom limb syndrome... phantom limb syndrome, yeah. common for those with it to say like it's permanently frozen in the last position it was ever in, when it was still there, forever. for many it is even quite painful. that's the polar opposite of... ...rubber hand illusion: they call it "proprioceptive drift," heh. that's almost my word i need, or phrase. it's more like "proprioceptive flexibility." or plasticity. your mental map of your things, what you regard as part of your body and what you don't, is flexible. probably simplest way to get your foot in the door is guided meditation. you walk through body, every little bit, in order, and feel it, say hullo for a moment. if you can say still/focused enough, very quickly, you'll start to feel illusions like your hand is becoming gigantic (until you become the sensory homunculus [then eventually a sphere]) so, i guess, i am temporarily accepting some arbitrary cluster of knobs, or faders, or buttons as an extension of my proprioceptive map. at the start, this was very fragile, i had to really almost meditate on a position for a few minutes. now, just kind of position whatever, fuss around a little bit and get myself settled, and i'm there. walking down the street in a busy city, i also started to feel a weird thing. like there was a bubble of awareness around me, of what i was allowing to reach my conscious mind. i realized i could expand it or shink it: focus close around, focus wide out. then i noticed, kind of startled me really, that other people seemed to react. then i realized i could focus it like a flashlight, and people would react for more often. not always, mind you. but enough to be more than sheer chance |

i need to design a shoe that has gate outputs |

i'm aware That 1 Guy has his magic boot, which is like, i dunno, that has some stuff going on. but it's more just a little foot shaker noisemaker and a sample trigger i think with an expression pedal i mean, i have a midi pedalboard. i should give that another stab. it was just too big and clunky really. but it's not even expression, i don't think, just oversize foot buttons. that the tendons powering the left shift key were screaming uncle but i have to keep working? so i took apart an old ps/2 keyboard and turned it into a ps/2 left shift key with a 1/4" in. but then a sustain pedal is too heavy. and i'm on to researching, like, good foot buttons no, none of that. not what i mean, here. like the car is a very controlled acoustic environment because the manufacturer has complete control over the space, a shoe surrounds your foot. and you can't easily do this with your arm. even, like, neoprene would slide about too much. and since you have the whole foot, in a reasonably reliable position, you can then use some AI tool to take the cloud of noise from a dozen sensors pressing up against the foot and gradually extract usable configurations. which may not even be as specific as "wiggle toe" |

take the cloud of noise from a dozen sensors pressing up against the foot and gradually extract usable configurations that's essentially how the brain leans to control the body, by the way. one of my favorite wild-but-plausibles is that hiccups are a way to bootstrap voluntary control of breathing. a sonar ping guide the wiring |

hmm, or perhaps somewhat supervised learning. you dance to some chopped, programmed amen break as the shoes (ecg, accelerometers, pressure sensors) record data to your phone via gruetoof. then you feed some neural network the data from the shoe sensors, plus the MIDI file that generated the sequence of chopped amen you were dancing to. an hour or three of dancing later, you switch the model from "record" to "play" and then have it guess at which sample to trigger based on how you dance. and that this is far less cumbersome than using stickers to hold a sparkfun stack to your arm for a single CV output. more pleasing to the user, as tim cook might say |

i dunno. i guess there's more of a basis to it. like sez ~ right brain, involved in learning new activities. left brain, involving learned activities. one nice inflection point is that learning activities can become a learned activity. obviously needs to be good coordination between both my left brain runs the machines, while my right brain figures out what to do next, and/or debugs problem(s) being encountered -- the keystep interface froze but it's still playing? how do we escape this one without stopping the jam? so it's more like being able to leave something alone for a while and trust the machinery underneath to switch me over if it's necessary. interrupt request: the keystep is still playing in a fixed autistic loop; we need to temporarily suspend figuring it out for a bit to go shuffle some fx and change the drums. but as i'm doing that i'm not thinking about what knobs to press, i'm also planning. try to save the project. may not work; who cares, try. flap up some stuff it's not running with dub feedback to buy myself a window. reboot. pray but then i discover i can have a conversation with someone while doing this, now, and, yeah, i got a bit excited sorry (and you'd never have known the keystep crashed if you listen to the recording, btw) |

was just dancing about to "phat planet" by leftfield and i'm pretty warmed up; dancing a while already. and i jacob jingleheimer-schmidt my fingers, obviously, to make sword motions. that i linked this track to a colleague and his initial reply was, "oh, this sounds like they were referencing kill bill, it sounds like [haven't analyzed yet]" but no this was 4 years before bill /bin/kill -9 or maybe there'd be a more witty unix signal to use other than 9, given how bill... oh, never mind, this is too esoteric just posting to say that i give thousands of hours of dancing, more thousands of hours driving the car, and also quite a few running machines, thanks guys, you're my favorite things in life. |
