I imagine that most Csound composers of live-electronics pieces rely heavily
on FLTK, except for the Mac - if only for their works to readily adapt to
the wide variety of control surfaces. The exception would be those composers
who intend to be the only ones to perform their works, probably always on
the same hardware device.

I'd be interested in hearing of any composers on the Mac OS's who routinely
use FLTK widgets. (I assume that until recently FLTK didn't work on the
Mac.)

To be sure that my works *can* be performed by others - on many devices,
I've collected (and continue to collect) a large number of such  - currently
20 or more. (I also document my works extensively via an instructional text
file.) Only two or three devices are keyboards. (None of my pieces require a
keyboard, although at least one is performable on such.) eBay has been
invaluable in this "controller search".

I may well do an article on "tips for writing for a wide variety of control
surfaces," including a segment on "what to look for in a control surface."
The only thing keeping me from it is the feeling that my experience may be
much too personal, and that there's absolutely no substitute for user
experience in this area.

Last time I looked at your works they required csoundAV which does not run 
on any of my machines capable of realtime outout.  has that changed?

Hi Art, others,

To achieve compatibility between Mac OS and Windows/Linux for 
compositions, I have found it quite effective to create abstractions of 
concepts such as UDO's (for a log slider for example) then use a 
generic, linear control slider in any arbitrary frontend/wrapper/UI.

I use csoundapi~ for Pd on both PC and Mac and I've found the 
invalue/outvalue mechanism to be quite useful, however the best seems 
to be to use UDOs - especially when using Csound5's interapplication 
communication protocol OSC implementation, for example. You then no 
longer require any sort of FLsetVal in your orc and it seems to make 
things generally cleaner.

I tried to develop a realtime system for Dr. Boulanger to use with the 
p5 glove at the Sounds Electric '05 conference and I seemed to run into 
several problems with the FLTK implementation in Csound5 - so much that 
I simply dropped the GUI and just make a standalone Csound file that 
printed the necessary information to the standard output :)

Some of the problems could have been related to the fact that I was 
using a version of Csound5 compiled on Mac OS 10.3 with noFLTKthreads=0 
and Dr. Boulanger was using a version of Csound5 on Mac OS 10.4 with 
noFLTKthreads=1. The oddities were so strange .... one such oddity was 
the fact that the sliders were all reversed!

In general, it seems that the invalue/outvalue implementation seems to 
be quite transparent between MacCsound, csoundapi~ and the new 
TclCsound, although I prefer to use UDO's in my compositions to 
facilitate maximum transparency between Mac, Windows, and Linux (I use 
all 3 regularly and I cannot waste time with implementation details).

TclCsound is the FLTK of the future, IMHO.

Peace be with you all during this holiday season!
