First of all, thanks to Steven Yi for his comment on the previous post about Deep Note (the THX sound). For those of you who don’t know, he’s a Csound master and author of a timeline based composition environment for Csound called Blue (see http://www.csounds.com/stevenyi/blue/index.html)
Meanwhile I’ve continued my experimentation with the Hans Mikelson instrument gran2. The problem with it was that it took 180 seconds to compute 8 seconds of stereo output, so tweaking it was a slow process. I decided to try using a newer opcode called “grain3” (introduced in Csound 4.15). I guessed the right parameters to use more or less and ran it, and it sounds pretty good. It runs essentially in real time with less than a 50% CPU usage on a Celeron 2.2GHz. (The csd file is appended below.)
I still need to tweak some parameters and envelopes on it as well, but at the moment it’s a very promising approach. It’s quite different in design from what I read in the article pointed to by Steven, but I supposed that will make sense later.
Incidentally, I have been struggling to get Csound programs to look right in WordPress, but I haven’t been able to figure out how to do it.
In the WordPress FAQ they mentioned a very cool site called pastebin (www.pastebin.com). This is a site that allows you to post chunks of code that other people can read. I created a “private” pastebin called http://csound.pastebin.com that I’ll use to point to my examples and snippets.
So here’s where you can see my take on grain3.
