This sounds like it would be worth a shot too. How is Boa Constructor in 
comparison to Fluid? Maybe it would be worthwhile to have a couple of 
examples, one in C++, one in python. One obvious advantage of the 
C++/fltk, as I see it, is that one could make a small fast statically 
linked standalone csound instrument/app with gui without needing python 
installed or the runtime overhead of Python. Disadvantage is harder to 
write I guess.

Also, I have a better idea than an ear training app for a small embedded 
csound gui demo. I was thinking that something very useful would be a 
generic virtual controller surface in which sliders and buttons send 
values directly to csound tables or output values as score events, with 
the output being adjustable from the app. So say there were sixteen 
widgets on screen for example, you might have a tab that allows the user 
to change which table and index each slider goes to and which score 
events the buttons send, along with the ability to save snapshots of the 
configuration and the current values. One could also add the ability to 
save the snapshot as a text file suitable for loading in csound using 
gen23. This could be a great way to tweak table based instruments in 
real time and save the values, and just a generally handy way to make 
low overhead low priority gui controllers for real time use. It would 
also mean that users who don't want to jump into building their own guis 
from scratch could use say a 64 knob 64 button generic example and just 
configure it themselves without having to write C++.

I see no reason the sliders could not also be made to receive midi input 
for remote control.

I am thinking fltk for C++ and taking Michael's suggestions for python. 
Anyone have good reasons to do otherwise? How does GTK compare to fltk 
for this kind of stuff?

For myself, being a newbie, my first steps will be small. I plan to 
spend the next little while just trying to make a gui with a couple of 
buttons that send an event to embedded csound5. If anyone wants to help 
or is willing to act as an advisor/tutor please let me know.

Thanks
Iain
