This is great. So do you have a custom version that uses midi
controller messages to manipulate the timbre in real time?

I'm having a lot of fun with this. My keyboard is at work so I'm using
Steven's virtual MIDI keyboard. I was half expecting the MIDI sliders
to control the sound. Great stuff. This is definitely one for the
collection.

Rory.

I'd love to try it. Can someone remind me how to do that in QuteCsound? Those
FLTK opcodes don't compile.

Also, according to the manual, FLpanel must be followed, sooner or later, by
FLpanelEnd. That doesn't seem to have been done here. Is the manual wrong?

--JA

There is a FLpanel_end in it. It works well here (OSX10.5). Nice sound  
out of the box.

Okay, so there's a typo in the manual. And also in the syntax highlighting of
QuteCsound, which doesn't recognize FLpanel_end as a valid opcode when it
has the underscore character in it. (Also the lower-case 'e'.)
