Right, thank you, Robert. I've added asc()/ascending() and desc()/descending() methods to Interval.ck to replace invert(). michael On Thu, Jul 7, 2011 at 11:14 PM, Robert Poor wrote:

My question is this, what should the method on Interval be called that "inverts" it (from low-to-high pitch to high-to-low pitch)?

In music theory, one talks about an "ascending" interval (i.e. C' to D' is an ascending major second) or "descending" interval (D' to C' is a descending major second).  I can't think of a term of practice that turns an ascending interval into a descending interval, but maybe 'ascending' and 'descending' are enough to get you going?

Yes, the Samchillian is what I saw before. Thank you, Kas. If it is not too much trouble, I would appeciate seeing what you came up with. My end goal was an interface for the iPad, which I achieved with a ChucK script and a Control OSC template https://github.com/heuermh/lick/blob/bf2b6f9a265c5eb0a789a49a99461ba2838ded4... I can't say I like touch interfaces very much though, I greatly prefer the keyboard one. michael 2011/7/8 Kassen :

Hello ChucKers,

I wanted to emulate something I saw on youtube once (sorry, I've lost the link), an interval keyboard where keys on the right hand play notes increasing by various intervals and keys on the left hand play notes decreasing by various intervals.  I haven't any music theory and the wikipedia pages for muscial intervals are over my head.

I have no real answer to that, but maybe other help; Here is your link; http://samchillian.com/aboutsam.html And; I also did a take on it. I used a PlayStation-style joypad because those are more or less symmetrical. It worked quite nicely; it had preset sounds and a library of quite a few scales to use. I'd have to dig up the code though as that's on a old harddrive. Would you like it?
