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. Andrew
