Re: [chuck-users] NYC-Based ChucKists: "Cloud Seeding" Sept. 1st @ The Stone, 8pm

Hi Andrew, I'm glad you're coming to the show! I'm really excited about it. I'm looking forward to meeting you at the show. I would love to do a ChucK meet-up type thing. I know Zach Layton over there at Issue Project Room. It would be really cool to play with their sound system. They use the same kind of speaker systems that PlorK uses, but overhead and they are set up as a 15 channel system with a control interface in Max/MSP, if I'm not mistaken. I would love to do a granular synthesis thing there. But I'd be even more excited about setting up some kind of ongoing New York based ChucK meet-up / jam session. If Issue would be into hosting this, I think that we could really get things cooking here on the east coast. CVS access (correct me if I'm wrong, dev people) is obtained like this (on unix-like machines): $ export CVS_RSH=ssh $ cvs -d :ext:anon-chuck@cvs.cs.princeton.edu:/cvs checkout chuck_dev You'll get a folder called chuck_dev and inside that is a folder called v2 and that is where the code is.

A statement and two questions:

1. The Stone is awesome.  I mean, it's blazing hot and there's no beer, but it's one of the coolest venues for the purpose of hearing rad music.  And it's curated, so there's some sense of artistic direction that is semi-unique.  John Zorn runs it.  See you there, Mike.

2. How do you get this so-called CVS?  Currently, I don't really perform with ChucK anyway, so stability is not so much an issue.  The text input/output thing seems fun, though.

3. Is anyone else going to be there?  Can we do some kind of NYC ChucK meet-up?  I'm grant writing/volunteering at ISSUE Project Room in Brooklyn, and we've got this excellent 15-channel floating speaker system (pretty sure Ge knows some Princeton people who have played there) and that would be a cool setting for a ChucK livecoding jam.

Thanks everyone.

Andrew

Hello,

If any of you are in or will be in the New York City area this coming Tuesday, I'm playing an hour-long set at a place called The Stone that will be all about Granular Synthesis / Resynthesis in a performance setting.  If you'll be in the area, it will be a cool show to see--everything is written in ChucK.  I'm planning on doing a quasi-participatory didactic thing with the audience to teach them about granular synthesis as I demonstrate the instruments I've built, so it's a little non-traditional as far as concert flow.

Even if you won't be in the area, you might want to take a look through my (spaghetti) code.  As Kassen can tell you, my attempts at doing granular synthesis in ChucK border on obsession and have spent a long time trying to squeeze out as much performance while keeping it as easy to program as possible.  For this show, I've built instruments that take their spectral profiles from small audio files that I've run through the Spear program for analysis (http://www.klingbeil.com/spear/).  Spear does "Sinusoidal Partial Editing Analysis and Resynthesis" and does a really good job at FFT analysis with transient sharpening and all kinds of other goodies. Spear outputs its information as a text file and I'm using the file IO routines that are currently only in the bleeding-edge CVS version of ChucK to parse these files into reasonably useful datasets.  Then I'm using standard HID stuff and a modified gamepad for interaction.  It's far from perfect, but it's a playable prototype.  I'll have this stuff organized and posted on my website and github by the show date (hopefully).  I'd really love to get some feedback on the code for the future.  Plus, if anyone is interested in getting a head start parsing Spear files with ChucK, this might be helpful.

There's a possibility that I'll document the show, so there might also be video at some point.

-Mike
