Short Variations on Ravel

Filed under: Uncategorized — Tags: , — Graham @ 6:00 pm

For a while now I have wanted to create a livecoding composition by varying the phrases below:

Page 4 of the quartet, the modal theme

Page 4 of the Ravel String quartet, the modal theme

Recently I implemented this idea–for a DVD call in the livecoding community. Using Supercollider, I realized the original score in code, and was able to make some basic variations on it. Subtitles attempt to explain what is going on to the listener. You can watch the variations below:

You can listen to the original excerpt on Youtube from American String Quartet.

In the course of developing the piece, I made some shortcut/extensions to the Pattern class, which can be found here: gkcPatternExt.sc.

PS In my search for the excerpt, I found out that I’m not the only one recently stealing from this quartet. Andrew Bird on Ravel riffs on the pizzicato-heavy second movement.

Update: This piece has been accepted and published in the livecoding-focused DVD accompanying the Winter 2011 Computer Music Journal (Volume 35, Issue 4). The program notes were available at the time of this update. Links to some are posted on this TOPLAP wiki page.

Octane shows

Filed under: Uncategorized — Tags: , , , — Graham @ 2:58 pm

Here are two long-form sets from Octane Coffee in Atlanta 2007. More information below:

By that time, we knew the place quite well; Atlhack had meetings there. Much thanks to Tony from Octane and Gavin for giving me an opportunity to play! Both performances used ChucK exclusively.

The first gig was on May 29th, 2007. Since it was a long set, I ended up using both newly improvised material as well as stubs that I had recently developed for the Atlanta Laptop Battle series that year. As well, you’ll hear “Sample Forest” sections that I pulled out with the sample-based composition tool I was developing (Mused). Here is the recent edit–I removed some of the many glitches:

The second gig was on August 8, 2007. I remember having made a change in my setup that allowed changing the tempo in mid-stream, but there was a code error, leading to the out-of-phase tempos you’ll hear below. The set is also book-ended by a real-time WiiMote instrument and a sample from the Ravel Piano trio. Besides the clean synthesis, I also miked the room to get in some of the ambiance of the place. Enjoy!

at Placard Sheffield 2011

Filed under: Music — Tags: , , , — Graham @ 6:20 pm

Ok, so I recently performed at Sheffield Placard 2011, a headphone festival hosted by Alex McLean and the excellent folks at Access Space, an open technology center unique on its own merits. Over the past few years, he has hosted several such, being inspired by the original le Placard festivals which originated in Paris. The atmosphere, the participation, and people were great, and I hope they will continue to host them in the future (special thanks to Alex for making it all happen!).

Alex kicked off the festival around noon with some binaural films. For me, some of the most memorable performances were:

For my contribution, I gave a simple livecoding set using Supercollider, starting from this stub file with a simplified version of the Promenade from Pictures at an exhibition (which I used in other recent projects). As a backdrop I used a recent Barcelona field recording I did as part of the Hertziosfera-Sounds of Gracia workshop, which focused on field recording of everyday soundscapes.

I think it turned out alright, though the recording is a bit clipped. The most interesting parts are the last 5-10 minutes. Enjoy:

Hackpact 2009

Filed under: Uncategorized — Tags: — Graham @ 8:52 pm

These were to be my entries for Alex McLean’s Hackpact in 2009, but I ran out of steam. Javi was egging me on and made a far better showing, though there are definitely some things I’d like to build on in the future.

Day 4: wiicord testing

Filed under: Music — Tags: , , , — Graham @ 10:37 pm

For a while I wanted to make a simple chording interface for the wiimote, mostly for performing cheesy cover versions. This one uses the circle of fifths as different radial positions on the directional pad, button A to play a chord, button B to change the triad to minor.

This one needs GlovePIE, my most recent pie->OSC script is included.

With a bit of Spanish 80s sensation, Heroes del Silencio:

Day 3: Difficult Level

Filed under: Music — Tags: , — Graham @ 2:04 am

Falling further behind. Code stuck in an unsaveable state in the Audicle.

Chromatic parallel intervals generated by a mod (13, 18) create the main voices, and standard games with rhythmic delay.

Day 2: Slow Sequence

Filed under: Music — Tags: , — Graham @ 1:38 am

For the second sketch I wanted to find a use for slowly growing sequences, a key concept in Jason Freeman’s MetaMix, which mixes chunks of a music file mapped from a choice of these sequences and creates a seamlessly endless mix from a short piece of music.

Originally I thought of using the sequence as a chord progression, but it moved too slowly. Instead I directly used it as a voice, and put several voices in canon with the sequence as melody. This avoids the standard trick of using mods to wrap sequences to a desired range; it still ventures into higher territory, but doesn’t stay there too long and doesn’t go off into space.

Apart from that, there are a few cheesy rhythmic delay effects care of the LiSa ugen.

The sequence used in this sketch is A005590 (link from ATT Research).

Day 1: Catchup / One Osc Scuffle

Filed under: Music — Tags: , — Graham @ 12:50 am

Greetings. Day 1 the site was down, so I’m behind on documenting/posting. A little later I’ll get into background.

h01: One Osc Scuffle

hp01

The first day. Nothing too ambitious. Recalling basics in pd. Two pulse counters making the rhythm, an osc~ with note sequences, and a sampling buffer.

The sound will be here: hp01
The patch will be here: hp01
