Scale & diatonic
by Hans Aberg 12 Oct '11

12 Oct '11

I have made a program, scale.ck, that admits one to work with scales, including tuning stretch, céleste tremulant, retune them, and then save to a file, with a line of code that can be pasted back into the source, available at next program startup. Scale tunings can be put into tuning banks, and otherwise defined by your favorite method. Details in the file. I have also updated my program for diatonic tuning systems, diatonic.ck. Just a few changes: adding some common tunings, fixing typos. The files are available here: http://www.math.su.se/~haberg/tuning_systems/ Hans

Re: [chuck-users] Using Fourier Transform

Those are some great FFT resources, Rebecca - thanks for sharing! I also wholeheartedly second the recommendation for the DSP Primer book. In addition, I have linked the following FFT overviews to people who are intimidated by articles that lean towards the more academic end of the spectrum: 1. The DFT "à pied": Mastering the Fourier Transform in on day: http://www.dspdimension.com/admin/dft-a-pied/ (The author of this article acknowledges that it'll take more than one day to truly grok DFT.) 2. Katja's homepage on sinusoids, complex numbers and modulation: http://www.katjaas.nl/home/home.html (Katja uses wooden anatomical dolls and photos to reinforce the mathematical relationships between complex numbers, sinusoidal waveforms, etc - useful for building up mental models) Cheers, Anthony.

Re: [chuck-users] bryan Eidel's problem with DAC in MiniAudicle
by Perry Cook 31 Jan '11

Aha, this is a known problem with Mini where it loses it's mind as regards the audio device(s). Happens most often when a sound device has been plugged/unplugged, but can happen when you've changed devices otherwise. Fix is easy: Go into MiniAudicle Preferences and hit "Restore Defaults" button. (if you had file paths set up, then you'll need to go and fix those again). But after that Mini can see the DAC again.

Re: [chuck-users] m-A to Quartz
by David Loberg Code 29 Jan '11

I can pipe m-A to Quartz via Soundflower, but then I am not able to hear it. I tried combining Soundflower and the regular audio output by making an aggregate audio device with OS X's Audio/Midi Set-up. This solution doesn't make sound AND doesn't affect Quartz. > Hi David, > > Yeah, Soundflower is what I would use for this.

Frequency domain and fractals?
by Wolfgang Gil 29 Jan '11

29 Jan '11

Hello, Does anyone knows about any interesting book, paper, etc using chaos for sound generation? I have seen some documentation about chaos and music but until now everything has been related to the organization of the notes through a "chaotic system". None of them to the actual generation of sound. I'm wondering if it would be interesting to employ non-lineal equation's systems to populate fft matrixes (like the Gabor matrix) and then translate that data into sound using inverse fft... Any thought? -- Wolfgang Gil http://www.wolfganggil.com

The ChucK Method Book
by Zed A. Shaw 28 Jan '11

28 Jan '11

Hi folks, long time lurker, infrequent poster. I've recently finished a book for Python and I'd like to do a similar one for ChucK. The Python book is "Learn Python The Hard Way" and it's written similar to a guitar method book: http://learnpythonthehardway.org/ What I'd like to do next is a "ChucK Method Book" in a similar style, but actually make it more like a real method book for an instrument where the student is learning to "play chuck" like they would an instrument. If I were to do this, what do you think it should include? Do you think it's a good idea? Have you tried teaching ChucK? Thanks! -- Zed A. Shaw http://zedshaw.com/

Hi David, Yeah, Soundflower is what I would use for this. Set miniAudicle output device to Soundflower (2ch) and Quartz composer's audio input to the same. Sounds like you're doing something interesting! Best of luck, Anthony.

m-A to Quartz
by David Løberg Code 27 Jan '11

27 Jan '11

How can I send the audio output from mini-Audicle to the input of a Quartz composer visualizer? (I want the m-A audio to go out to speakers AND to Quartz...just like iTunes.) Do I use Soundflower? Do I need to create aggregate audio device? thanks, david David Loberg Code School of Music Western Michigan University Kalamazoo, MI 49024 269-387-4667 code(a)wmich.edu

Re: [chuck-users] Chaos functions in ChucK.
by Anthony Bowyer-Lowe 25 Jan '11

25 Jan '11

Hey Ronni, I have been meaning to implement some chaotic type functions in ChucK for some time: Perlin noise, Buchla-esque source of uncertainty, Brownian motion LFO, composite complex modulation sources, etc. I have some personal audio design projects coming up for which I intend to prototype the synth system in ChucK so, if I get time, if you're lucky, and if I make anything of worth, I'll share what is produced. A. > other question , Do any body have made chaos functions in chuck? or > maybe there are examples of this? >
