SAE Education Essay on Aphex Twin/ Max Msp algorythm patch

[Defn]

Hey Zoe

 

i've read a bunch of your posts on other threads and they always prove to be very insightful!

 

Ill put this code into supercollider and check it out, thanks!!

[Defn]

can i ask? where you sourced this code from?

[mcbpete]

Admittedly I'm not up on SuperCollider but that appears to just rotate a shape in 3 dimensions (the AFX logo maybe?)

[ZoeB]

Thanks for the kind words!

 

can i ask? where you sourced this code from?

 

Sure. The SuperCollider mailing list archives, specifically this message:

tron game patch I posted here a long time ago,
looks pretty,
oh its SC 1 aswell of course.
let me know what ye think.

Warning: he doesn't come off very well in these archives. His music's often great, though.

[ZoeB]

And of course, it's no surprise to see that Marf posted a link to this two years ago. I think he's the one who showed it to me too, if memory serves.

[Defn]

what is his moniker? on the link you posted

 

thanks zoe

sorry i mean if you click on the link you posted, then go on the message archives @ this link http://www.audiosynth.com/files/sc-users-archive/

 

then which user is it?

[Joyrex]

Richard's old email used to be eric_hard_jams@btinternet.com back on the SC mailing list.

As above, Eric Hard Jams, a pretty simple anagram of Richard James (just move the E). Just search for "var zss ox oy oz thX thY thZ" to find that post.

[mcbpete]

BTW you should get some extra points if you spell it 'Algorithm' rather than 'Algorythm' in your essay ...

[Alcofribas]

What about Alcorythms?

[Defn]

yeah soz about the spelling, i always just rush with my typing. I doubt it's that important for forum posts!

[Defn]

Does anyone have anything else to chip in with? maybe some handy tutorial vids or books on DSP?

 

I also have to do another essay next year and i was going to base it on controlling a analogue modular system, via a algorithm in max/msp and then have a interface with a ipad controlling the patch, using lemur or mira app!

 

so if anyone has any thoughts that be great!!

[mcbpete]

I've got these two books and they're bloody ace - especially the one on the left:

 

[Defn]

oh yeah i came across the one on the left recently, think ill place an order for both of these tonight!!

 

cheers for heads up!!

[mcbpete]

The one on the right has pages that feel nice - sounds weird but when you get it you'll understand !

 

They're quite heavy going but I promise you - If you persevere (as I'm trying to !) you'll learn a hell of a lot about both the Max and MSP realm, and audio design in general

 

Online there's the Baz Tutorials that I've been meaning to follow, but they've come highly recommended - http://www.youtube.com/user/BazTutorials/videos

[Guest Jimmy McMessageboard]

Aphex use Max/MSP? Are you sure?

[mcbpete]

Possibly - I mean there's a chance the piano stuff from Drukqs and his recent live performance was a custom Max patch triggering some external hardware

[Guest Jimmy McMessageboard]

fair point. I just never put aphex down as a max user but I guess you can never tell because max is what you build not its own sound that you can spot, although maybe there are clues when you hear something in a certain way

cubus question - is your learning max etc why there has been no new cubus music since forever!

[mcbpete]

Absolutely, Max can used for anything - to manipulate midi, hardware, audio, video, just anything you can chuck at it ! It's just a tool kit that can make whatever you to do, and can sound as organic and conservative - or as electronic and wild as you want it to be.

 

Aye, been learning Max & Ableton which has been why there's been so little over the last year. Plus work and personal commitments (especially for the other half of cubus) has meant I've just had so little time being able to focus on anything. This was my first real thing since moving from Buzz - http://cytoplantastic.bandcamp.com/track/rejected

 

And the soundtrack to this being my second -

 

[Defn]

I wouldn't say Aphex is just a core MAX user, as he states on the super collider archives that he tends to use supercollider for big patches, where as he states that things like max & reaktor are good for just small patches.

 

all this + metasynth...me thinks?

 

but who knows could all be internet speculation

[Guest Jimmy McMessageboard]

and hello to jason isaacs

[rekosn]

defn have you checked audible design by trevor wishart?

is ace for learning about spectral processing, think it was made for this soft:http://www.composersdesktop.com/

I suppose its possible to implement the ideas in max

heres a nice video of rich and max

peace

[mcbpete]

I wouldn't say Aphex is just a core MAX user, as he states on the super collider archives that he tends to use supercollider for big patches, where as he states that things like max & reaktor are good for just small patches.

Aye but that was about 15 years back - Max has moved on quite a bit since then, especially with the implementation of externals/subpatches. And the 'new' Jitter & Gen~ just add to the amount of mischief you can get up to - If you know what you're doing (which I don't, cos at the moment all I can do is make is Eleh style sine waves drifting all over the shop)

Huh, apparently so.
