Ostraka with Dial System Performance

ostraka_at_kckMy new experimental music project with Graham O’Brien, Ostraka with Dial System, will be performing on December 20, 2009. Originally I had written that we were performing on December 8, 2009 as well, but that performance has been canceled due to a prior engagement.

Ostraka with Dial System is myself on laptop using my custom developed application, the Gestural Music Sequencer (GMS), and Graham O’Brien on drums. For more details, including audio examples and video produced using the GMS, checkout the GMS category. There’s also a Gestural Music Sequencer Documentary Short produced by Josh Clos, that does a good job of illustrating what the software does.

A Quick Note About My Music

Precambrian ResonanceSome of you might not be aware of the process to get electronic promos of my music for reviewers, radio, music blogs, publications, music venues, etc. If you’re in any way involved in the music industry please complete the Unearthed Music Service List Application.

As soon as your application is processed you will have access to download full length 320kbps MP3 files of all of the music currently available on Unearthed Music including my solo album, Precambrian Resonance by Ostraka. Don’t worry about being spammed because we send out no more that five or six mailings per year. Here’s Blitzen Machine.

84 Caprice Featuring Prof – Karma the Uh Oh Beat

My friend and hiphop producer Cornelius Noll (aka 84 Caprice) recently offered to share a track on ACB that he produced for the Renoise Efficient Music Competition. I just got a chance to preview the track, and while I’ve been quite fond of 84 Caprice all along, he has managed to conjure something special this time. Here’s what he had to say about his process and working in Renoise.

profandstpaulslimx225wide_jpg_595x1000_q85This particular track is one that started out as an instrumental for Prof, an MC on Stophouse Records where I get most of my work done. The original draft was created in a program called Renoise which falls under the category of “tracker” or “tracking sequencer”. It quickly became an exercise of figuring out how to truly work the insides of the program it was created in for a contest conceived by Renoise and Indamixx in conjunction with CreateDigitalMusic.com. Upon initial approach it looks like this; make a bomb track and license it under Creative Commons. I won’t discuss C.C. But will rattle a bit about Renoise and the technicalities of making fight-night weight.

These days I typically use a piano to work out ideas and then graduate into software to execute them. Renoise tends to be my favorite place to land as it loads up like butter and is quick for nailing down concepts. The implied constraints of this contest, however, had hoisted a series of difficulties in my process. The first being that while I like to use VST/VSTi’s in the process, non-native sound creators or effectors were not to be used in the final version. The second concern was the size of the Renoise file as the winning entry will be used as one of the demos within the program (I haven’t had to deal with file size since I turned my 1.44meg floppies into coasters). Third concern – CPU usage. I was shooting for a great track weighing in under 5 megs. My rough track was loaded with complex VST/VSTi’s and was well over 20 megs.

The process was actually more focusing than I imagined. Imbedded capabilities include “rendering” which allows creation of samples of MIDI performance very similar to a “bounce to disk” but without leaving the program. This proved helpful with some of the trickier performance passages. It also lent itself well to taking a small sample of more simple instruments allowing for creation of patches (which I have never made the time to do in Renoise). If you look at the file itself you will find within it instruments which approach “chip-tune” file size all the while maintaining my vision for a very anthemic quality to them. I found as I rooted through the sequences and the instruments that my samples were converted at 32 bit 44.1khz; this was rectifiable within the program. I reduced resolution on lower frequency and less important pieces. These were huge in dropping file size down.

Skipping ahead a number of hours, we now have the track entirely reconfigured. No external instruments. No external effects. Less than 3.5 megs (this just blows me away). While the original track would load my laptop to as much as 40% CPU usage, the current CPU loading on my laptop does not exceed 11%.

Oh, and the track is kinda large.

Traversing Samples with Granular Synthesis

messy_patchI have begun to refine the patch I described in the last entry, creating an instrument that allows you to traverse through samples using an x-y controller and a slider. The x axis controls the forward or backward playback frequency of the grain. The y axis controls the width of the grain; either very narrow (minimum of 10ms), to an adjustable percentage of the sample at the widest (15% by default). The slider controls the position of the grain in the sample. Buttons across the top allow you to choose one of five preset samples. Alternatives can be loaded in the patch or set as defaults.

So far the TouchOSC controller is working quite well for the project. It was a bit tricky getting the interface to reflect changes in the patch, since radio button behavior is not supported in TouchOSC. Fortunately it supports an input port, so I managed to get all the buttons toggled properly by sending data back to the iPod Touch. I have connected the accelerometer to a filter so that when turned on with a toggle, tilting it on the y axis causes a lowpass filter to effect the output. Finally, by setting a threshold on the z axis, giving the iPod Touch a brisk shake will cause the patch to loop a randomly selected grain of random length from a randomly selected buffer played back at a randomly selected rate. The variety of sounds possible with five short samples is huge. Here’s a selection of sound produced with one sample selected. The sound source is from a vintage video game. I’m curious to see if anyone can recognize it. Please post your guess in a comment.

Etude in 8 Bits for Multitouch Graintable Synthesis

MAW Media Mash-up at the WBSC

Earlier this month I shared an excerpt of music from a performance at a recent Minneapolis Art on Wheels exhibition. MAW artist, Andrea Steudel, did some excellent video documentation that highlights the artwork and sound that transpired at the event.

The audio quality is quite good, considering the conditions in the space, and goes a long way to illustrate the ambiance during the night. Please enjoy the video and checkout the original post at http://minneapolisartonwheels.org/content/media-mash-wbsc.
