Re: [music-dsp] Introducing myself

Hello Bill, I take your question as a chance to introduce myself. When you sweep the input parameter you are introducing discontinuities in the output signal, and that sounds awful. The simplest case to figure that out in your code is imagining that you have the input variable set at 0 (pan = 0),

[music-dsp] Introducing myself

Hello, just thought I would introduce myself to the list since I've been lurking for a little while but haven't posted anything yet. I'm been programming computers since I was 9 years old, so 27 years now. I got started on a zx81 - it had a whole 1kB of user memory! I've never really done too mu

To continue this very important and not at all didactic discussion: I see some of the sections as semi-circles on either side of the middle line. So there's no actual circle data on the dividing line, but rather there's a point from the top circle and a point from the bottom circle on either

That's close, Phil. But to really get it you need to find a way to output two sample values in the same sample period -- they've got the ellipses joined at the zero crossings! On 2/22/12 2:25 PM, Phil Burk wrote: I couldn't help myself. The Google waveform appears to be made of random ellipt

Yes, it's quite a challenge to compose music just using C/C++. Lately, I have tried to compose entire pieces written in C++. Many of them are just monolithic feedback systems with oscillators, filters and some low-level feature extractors. There are no hierarchic levels of control functions, the m

I've tried that before, basically writing a soft synth and a sequencer. I won't pretend I made anything that sounded very good but it was fun. In the demoscene there is a whole field of 'programmed music' which is just this, although generally they use a sequencer for the composition and just co

It's nice to see some familiar names in Csound's defense. Here's something I've considered since learning C: has anyone (attempted to) compose music in straight C (or C++) just using the audio APIs? I think that would be quite a challenge. I can see quite a bit more algorithmic potential there tha
