English Subtitles for GenJam's Journey: From Tech to Music: Al Biles at TEDxBinghamtonUniversity

Subtitles / Closed Captions - English

okay so you're probably wondering what surgeon GM

wealthiest with the word apart the two pieces really stand for the genetic the genetic Park Country genetic algorithms in jammers are people to go to jam sessions which which engine so Jen jam uses genetic algorithm but the best way to understand which engine really does is to play it to so we're going to do so have an annotated performance

in this is a tadaima into monument I am from the forties our group with seven courses I love it and to anticipate what we're doing as we go to explain gym do me

well do day way rumored thank you from

thanks for the applause give me a chance to get all soapy water so why how to do that how does ginger work well what you just heard was a musical conversation between the two of us I'm the human issued arm I was improvising and as I was improvising Jim James listening in responding in producing an interactive response we had a little

conversation going now Jen Jen needs to know some things about to be able to play on it like those cords that you saw going by you get to see the chord progression knows what temple to play arm it knows what to do for each of those courses that use of flying by arm we need also set up

the tone generator so that Jen Jen was playing a tenor sax their something make intersect are the piano's panhard right drums whatever volume I can other couple love MIDI files the cup laid-back one was ahead sequence and I was at Harmony part that you saw I kinda penciled in on the score are the rhythm sequence was the piano bass and drums

and to do their I use yes ban box commercial product around for a long time are hack around with that and and generate a MIDI file so that if I were to play a tune again you hear exactly the same thing innovation drums and you hear something very different for me and Jen jam isn't what I did in jim jams responding to me and make

to be very spontaneous there okay so back to architecture and the interesting part from the evolutionary computation you and that is two populations melodic ideas a measure population in a phrase population in this is where the chromosomes chromosomes well here's what they look like

arm what I've got here's a cooked up example to illustrate how the architecture works here I've got here about a phrase are the phrase population is actually 48 freezes as on any given to arm in each of those phrases then if you look at that the chromosome for that the genotype basically maps to

measures in the major population so in here we have a phrase is measure 57 fallback measure 57 all measure 11 column 38 and their those measures in the measure population let's look at measure 57 wanna got repeated and what you can see is that its chromosome has 8 sheen's

genotype each gene maps to an 8 note before four measures for Measure are some of those genes can represent rests some can represent hold notes or hold events which means that's right at the bottom corner so that's for the rhythm happens and a a lot of the events represent notes in

some scale roughly two octaves scale and the scale that use is determined by the cord against which that measure is going to be played so that's why even though measure 57 repeated in the first measure we get any natural for the first and becomes the flat second in there a becomes

she are basically that's because the skills for c7 cordon seven core have different notes maps bottom line is Jen jam cannot play theoretically wrong on like me okay in if you can't tell whether I meant to play wrong didn't i win so

Maria well that's what attack its music very bulimia only scratching the surface there's about three dozen mutation operator crossovers weird stuff but this is supposed to be a TED talk with ideas worth spreading so we'll see I do we're spreading here and to do that to ensure that I need to

go back to the title gen James journey from technology music where you can take the journey literally because we've been all over the world together playing with this crazy thing over the years got a lot of nice opportunities played some interesting places

concerts and talks now I get to add add taxpaying to the list although I don't think I can fit them there um but really what I'm talking about is the subtitle from technology music and really what i'm talking about his journey perspective my perspective on ginger is represents what it is to me

play with a shorted out like most technologist when you start a project like this with the very technology perspective okay I was looking at as a technologist as a not a computer scientist anymore arms in the IT department but I was very much looking at the technology and I figured well T um I'll see what I can do with this try to make a play jazz in you know get some papers out a bit and get to go to

some nice conferences and have some fun there but you know what sounds great music itself probably just very very listenable but you know get some papers on and that perspective then that technology perspective is characterized by focus on the technology on genetic algorithms that's what I was studying

scientist about it and I was trying to study what genetic algorithms could do so I had to be really true technology couldn't cheat on the technology I had to make the technology correct in order to quickly assess it and that meant that if the music was not that great well I have to be in the music

the technology trumpet players have to stay hydrated there's an implicit goal with this kind of perspective and I sit in the artificial intelligence community certainly have evolutionary computation community and that is to generate things results

better human competitive in fact if you go to the genetic and evolutionary computation conference every year there is a competition on human competitive result very cool and for most the engineering domains dominate gecko are them extra good sense but when you do with an artistic domain

particularly music human competitive results can lead to this this a gentleman named John Wood he lives out in LA and he's seen here with his drum machines have no soul bumper stickers which he gives out unfailingly at the NAM show every year the name show is the National Association music merchants

they have a Mondo trade show fourteen hundred plus vendors in Anaheim every January and mister what's out there handing out his stickers is if you zoom in on the bumper stickers hard to read but it says at the bottom society for the re human is Asian American music

and this is a mean that has a lot of traction in society the idea the technology anti-human nothing new luddites we've had what I moments with this arm that that that's their arm the idea that if if if technology is used in music in particular there's something inherently wrong with it because music among the art forms

many people considers the most apparently human arm and many of you probably have that attitude I get it arm so how do I start wandering away from that techie perspective said that happen and where it first started happening was after I got the first version think bill in I'm training new soloists in

you're listening to an you know bear thats thats that's not bad so I figure we'll all play low stakes gig in in those days at rete there was a two-state re concert series it happen in the lobby there are two Union at noon on Tuesdays you set up your place at people wander by away in the cafeteria to get

launch and they might stop opportunity very low stakes so I decided to honor those I like 8 who's all arm and after I finished allowed thing happens got it time the organizer good sign up for this thing came out and said gee that was nice when can you come back

really so I stumbled sign up you know I'm a jazz musician always take any opportunity for getting so I signed up for and then we're back sort by: better to summer tunes I'll in G if it could do this kinda court I could do that too at that too in a resistor to think more about the music in not just a technology well to make a long story fit in a TED talk

I'm still doing gigs with it but my perspective now you is very different instead of a technology perspective my perspective is wandered to a musical perspective and that's characterized by a focus on straight up Jess sky music I like to play with people with this

to trade off a bit so its trade appears in my goal is to make good music isn't this fun for me to play hopefully fun for you to listen to any other surgeon at a Calgary them in there someplace but I've done a lot of weird things to it because I've been very true to the music

and that means I've had been the technology to music okay my explicit goal is that Jen Jen not just be human competitive which I mean probably is but that'd be a good collaborator so it's about the collaboration with me so I will argue gen James created

okay but that doesn't really bother me because the whole point is it makes me were created I'm a better trumpet player better chance player have more fun with this saying I got like three tard okay so really the bottom line here for the talk is it's not about the technology it's about music

not about the technology about music now can we generalize this here lies because we're all inundated with technology and we've seen examples that the the image I remember from the first half was the cell phone on the steering wheel

someone is driving you know the technology is is breaking so quickly what maybe it's not about the technology maybe it's about you in your life what you because the technology is not an end in itself

it should be driven by your experience and what you maybe that's the way to a comment technology nothing else so again it's not about the technology it's about the music sources about the music a better plan to and now that you know what it sounds like

in you gotta what rougher idea for a lil little idea how it works when a pointer to this one is gonna be another annotated performances we have before but you're gonna have to guess to something alive you know are I give me some him way to

Ste I'll this %uh bad dress

well in do a the little

you the

Video Description

Al Biles is a professor in the School of Interactive Games and Media at RIT, where he teaches software development, computer music, and interactive media courses to students in RIT's Game Design & Development and New Media programs. He has been developing GenJam since 1993 and performs with it a couple of times a month. He also performs with people as well, and he honestly can't decide which he prefers playing with. Al will soon launch an open source community whose goal will be to port GenJam to a computing environment from the current millennium in order to make it generally available.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
