@flawr Zwei has posted in CJam

code golf: I should probably look at a few but the only one I've used is CJam.

actual: I have flip-flopped quite a bit. I started with python then learned web stuff then java then C derivatives. I also learned lua at one point. Currently I use python for quick tests and experiments, and C++ for more serious or large projects.

my profile isn't fleshed out very much and I have very little activity because I am fairly new to SE as a whole.

flawr

oh ok, well I hope we see you around here every now and then=)

Zwei

thanks!

orlp

so does anyone have some feedback on soundcloud.com/orlp/twelve-tone-melody ?

Easterly Irk

yes

sounds nice

Alex A.

10:04 PM

@orlp I like it. I don't really understand the electronic tag though, sounds more jazzy to me.

Zwei

the first 5 seconds land right at the bottom of the uncanny valley for me with the constantly changing pace.

poi830

its good

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^^^^

orlp

@Zwei you mean due to sloppy play or just the rhythm?

Zwei

oh, this wasn't synthesized?

orlp

10:06 PM

you know, synthesizers are usually played by humans :P

Zwei

shows you how much I know about how music is played

flawr

Hm, if there are synthesizers there should also be analyzers.

orlp

synthesizer

Noun: Wikipedia

synthesizer ‎(plural synthesizers)
(music) An electronic instrument that creates its sounds with electronics and has a keyboard.
(music) An electronic instrument module that creates its sounds with electronics and does not have any keyboard.
(electronics) An electronic circuit that generates an electronic signal oscillation with accurate timing from a reference oscillator.
(electronics) An electronic device that generates electronic signal patterns to test an electronic circuit.

Zwei

I visualize music being made as people looking at a DAW laying out notes for a song. The DAW then makes artificial instrument sounds to match the laid out track

Jakube

@AlexA. Thanks. I build it mainly because I had some connection problems with the online compiler at the time. Compiling a code offline was a lot faster and than compiling it online. Also invested a bit of time in a few features like supporting testsuites and a better doc search, which the online compiler didn't had back then.

But since than, the online compiler got a lot better.

Haven't use the IDE in months.

orlp

10:08 PM

@Zwei the vast majority of music is played on instruments

Alex A.

@Jakube Ah, okay. Well I still think it's cool. :P

Jakube

The only feature that I miss is the automatically codegolf-template generator. .

Zwei

@orlp TIL.

The tone actually feels less akward and uncanny the more I listen to it

orlp

the reason why it's slightly awkward shouldn't be the rhythm

it's the fact that it uses all twelve tones in one melody

it's incredibly rare to do that

Zwei

yeah, it wasn't the rythm thinking back

aditsu

10:14 PM

@orlp you should call it "the quick brown fox"

poi830

lmao

flawr

Or alternatively in german das komplett verwahrloste Taxi

(the completely bedraggled taxi)

aditsu

@orlp also, the first bar (or maybe 2 bars?) sounds like Chopin - youtube.com/watch?v=wTSu1jjKpgI

orlp

@aditsu if that's the waltz op 64 no 2, then well spotted

(clicks link)

yep

first two chords are the same

flawr

@aditsu do you have absolute pitch?

orlp

10:19 PM

@flawr it's about relative pitch here

aditsu

I think I do, but it's not always accurate, so maybe not really absolute :p

orlp

i - II7 sounds glorious

flawr

@orlp I know, but these two seem to match quite exact if you compare=)

orlp

@flawr that's because C# minor is a convenient key for pianists :)

it has a lot of black keys

aditsu

I'm off by 1 semitone sometimes, possibly even more (rarely)

flawr

10:20 PM

Black keys = convenient?

orlp

@flawr yes

not for beginners

flawr

@aditsu What instruments do you play?

aditsu

@flawr piano, and a little guitar

flawr

Oh, well then=)

orlp

I prefer rubinstein's version btw

Chopin - Waltz Op. 64 No. 2 (Rubinstein)

aditsu

10:24 PM

I like Horowitz's version of everything Chopin :)

PhiNotPi

Looks like I came in at a musical time.

Optimizer

@orlp oh.. i remember that from piano tiles 2

flawr

Indeed=)

orlp

@PhiNotPi oh you missed my latest creation

twelve tone melody

soundcloud.com/orlp/twelve-tone-melody

with an interesting chord progression

aditsu

sounds a bit random/alien imo

orlp

10:28 PM

@aditsu that's twelve tone melodies for you :)

PhiNotPi

The part from 7-10 seconds sounds the best, IMO.

orlp

you have to use every tone in one melody

you can't play 'in key'

aditsu

can't you just go wild with the chromatic scale?

orlp

@aditsu but then it's not harmonic

Downgoat

@AlexA. how do I add two strings in Julia, "a" + "b" doesn't work

orlp

10:30 PM

my melody has some chromatic walks

but it's still harmonic

Alex A.

@Downgoat *

aditsu

or just walk the circle of fifths

Downgoat

@AlexA. wat.

julia> "a" * "b"
"ab"

huh

Alex A.

Yeah

orlp

@aditsu that'd be an incredibly boring chord progression

aditsu

10:31 PM

heh

orlp

originally I didn't intend to make a 12-tone melody

it sounded a bit more familiar

but it already used 10/12 notes

Luis Mendo

@orlp Very nice!

orlp

so I figured, why not 12?

aditsu

@orlp etude op 10 no 2 still sounds kinda harmonic

Luis Mendo

Music talk on 19B? Great! :-)

Alex A.

10:35 PM

@LuisMendo Are you a musician?

Luis Mendo

@AlexA. Amateur, yes. Here's a sample :-)

And you?

@orlp This reminded me of one of César Francks pieces: youtube.com/watch?v=qOUBl11wUbk

Wanna be able to find it again=)

Luis Mendo

@flawr Haha. Do you think it's a good idea? That's not very programming-related...

flawr

10:37 PM

@LuisMendo so what?

You are right. Besides, I also have a link to Twitter, which is also unrelated.

10:42 PM

sec let me record this other melody I was working on

Alex A.

@LuisMendo This is nice! :D Which instrument(s) do you play?

Luis Mendo

@AlexA. Guitar. Mainly electric, also some acoustic (Spanish guitar actually). I also use Matlab ocasionally for composing drum parts and synthetic bass parts, from samples of other songs

Oh and thanks :-)

Alex A.

You use Matlab for the drums? o_O

@AlexA. Yup. You get to say "I need to recompile the drum part". Pretty cool

Hahaha

Alex A.

That's super cool. Holy crap.

Luis Mendo

Lack of an actual drum set stirs your imagination

:-D

Alex A.

10:45 PM

I had no idea Matlab could rock the skins like that

Luis Mendo

Plus, the timing is always perfect

Too perfect in a way

@AlexA. You just read the "notes" in a convenient notation, and for each add an audio part read from a wav file. So it's just adding displaced versions of wav files, basically

Alex A.

Oh interesting

Luis Mendo

One for the crash cymbal, one for the snare drum, the bass drum, etc

My university is hosting an AI programming contest this weekend.

There's about a 50/50 chance I'll attend.

there

that's a melody I've been composing for a while now

not sure how to make a song out of it though

Luis Mendo

@orlp Since you like programming and that type of music, you should really read "Gödel, Escher, Bach", if you haven't already

orlp

@LuisMendo I have

Luis Mendo

@orlp and? Did you like it? I did, a lot

Although some parts were a little boring

orlp

I liked it but in the end it felt a bit pointless and empty

also it was slow at points

Luis Mendo

Yes, exactly. Some chapters I wanted to skip

But definitely worth reading

orlp

10:58 PM

so... feedback? soundcloud.com/orlp/unfinished-counterpoint

Alex A.

@LuisMendo Forgot to answer this. Yes, sort of. I've been playing the guitar for about 15 years and I used to practice often and play in bands and things like that (I've even recorded a couple albums) but I haven't been playing much lately. :/

Luis Mendo

@orlp I don't have much intuition for classical-like music :-)

Q: Substitution cipher

Luis Mendo

@AlexA. Hey! Bands! Albums! Any links?

Alex A.

@LuisMendo Haha the only stuff that used to be online was taken down a while back. It was on the band's SoundCloud but they took it down when they changed their sound a bit after I left.

The majority of the stuff I've recorded was before I understood how to use the Internet so it never made its way online. :P

Luis Mendo

11:03 PM

@AlexA. Well, you should! What style? Any reference bands?

Alex A.

What do you mean reference bands?

The bands I was in when I was younger were metal

Luis Mendo

I mean bands you like, to have an idea what yours sounded like

Ah, metal, ok

Alex A.

The most recent band that was on SoundCloud was some kind of rock...

poi830

in pyth how do you get a number corresponding to a letter

Alex A.

@poi830 The ASCII code? I think C?

No idea about Pyth(on), sorry :-(

poi830

i cant find it on the thing

@poi830 if you mean ascii code it's C

Martin Büttner

@mbomb007 you're not, you're just getting an empty match after every non-empty match because your regex allows it, and that empty match is replaced by a zero.

@orlp I was away.

@orlp some comments....

actually, are you looking for some (arbitrary) criticism?

because I can be specific about which parts I liked.

@KennyLau BTW Do you know Kevin Lau?

Kenny Lau

@CᴏɴᴏʀO'Bʀɪᴇɴ I don't think I do.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Hm. He's also on this site

PhiNotPi

Okay, the first 1/3 definitely sounds promising (as in, you can definitely build additional counterpoint off of it). The middle 1/3 sounded too repetitive IMO (I know that is probably kinda hypocritical if you've heard my stuff). The last 1/3 (with 2 voices) sounded pretty good. (The penultimate note sounded kinda weird, though.)

Kenny Lau

11:38 PM

@poi830 27 bytes by using map (you should learn using map): jmsm?&<JCk123>J96@hQ-J97kdt

@CᴏɴᴏʀO'Bʀɪᴇɴ I see.

2M  Is prime; pops a and pushes a!.
2$M Is composite; pops a and pushes Γ(a).
3M  Nth prime; pops a and pushes 1 if a is prime, 0 otherwise.

@El'endiaStarman Is this a typo?
