Dear all,
I just noticed that I accidentally send this to the DEV list instead of the
users one. That was of course a mistake. I hope this didn't bother anyone,
I'll try to pay more attention on the future.
Sorry,
Kas.

Fellow ChucKists,
Inspired by Scott's explanation of casting I thought I'd try a new trick
that may be quite interesting for livecoding.
first run this file;
-----------------------------
new UGen @=> Foo.instrument;
public class Foo
{
static UGen @instrument;
spork ~attach();
fun void attach()
{
while(1)
{
if(!instrument.isConnectedTo( dac )) instrument => dac;
second => now;
}
}
}
Foo foo;
new Sitar @=> foo.instrument;
//your melody goes here
while(second => now) 1 => (foo.instrument $ Sitar).noteOn;
--------------------------------------------
Then run this to hot-swap the UGen while the original code runs;
--------------
new Shakers @=> Foo.instrument;
-----------------------
Sadly this does need that "attach" function as assignment breaks the link to
the dac. I'm not sure I feel that's desirable behaviour but at least we can
now hotswap UGens without crashing. I don't think I succeeded in that
before.
Yours,
Kas.
