All right, after digging through the ChucK source code I found a few new methods--FileIO.seek(int) and FileIO.tell()--which made the whole thing far easier than I thought. In the process I also got the string.getat(int) method working, but couldn't decide whether it should return an int or a string. Right now (in my build of ChucK) it returns an int, and -1 if it goes out of bounds. I could probably include the patch here, but it's messy and gross. Anyway, Scala class works now. It reads in a file with Scala.read(string) and initializes with Scala.init(), then you can get a pitch with Scala.mtof(int). That's all it does--any other suggestions? The real Scala program does so much more that I hate to just short it like this. It even reads in the files that are mixed with cents and ratios, basically by just reading the first number and looking for a "/". If it finds one, it reads the second number and calculates the ratio, but if not then it calculates it as cents. You have to have the CVS version of ChucK to use this. Search "CVS" on the list and you'll find it posted often. Source code is attached. I'm up for suggestions, interpretations, reactions, anything. Paraphrasing Harry Partch, the only reason that a musical system is sustained is because significant music has been written with it. So keep ChucKing.

That is a great idea.  ChucK FileIO is kind of limited at the moment. I've been writing lots of pre-processing scripts in Python to make fileIO in ChucK a great deal easier.  I think that fileIO is really a great thing to have in ChucK and the better we make it, the more options we have for using complex data in our favorite audio programming language.

More when the storms pass...

All right, admit if you've made a Scala file importer. If not, it's about time that it was done, likely not to extend mtof() directly but rather as a separate public class/static method (like Scala.mtof or something). I know you're probably sick of hearing about microtonal things, but I've just been having a tough time getting a sustainable system going where I can work with an existing scale archive and develop my own tunings reasonably easily. I think a Scala converter is where it's at.

If it hasn't been done, can someone tell me (before I send this to the dev list) where in the source the FileIO capabilities are? I just finished building ChucK with Xcode, so I'm ready to dive in and make some mistakes. Side projects for extending FileIO also include implementing the tinyXML file parser, which would let us easily parse XML files with ChucK. So, hands up if anyone has been working with FileIO to a large extent.

I like this idea. Maybe it could be like a control shred, sending OSC messages with frequency parameters or something. That way it could be used as a control score in ChucK or SC. The pitch-bend thing only really seems useful if you're using standard MIDI-based VSTs. Andrew On Sat, Sep 26, 2009 at 7:21 PM, Hans Aberg wrote:

Manuel Op de Coul said a few months ago he wanted to do a seq to ck converter.
