[chuck-users] delay times of STK delays seem to be 1 sample off?

The idea would be to instantiate a chuck object like this [chuck~ 2
5] where the first number is the number of output channels and the
second is the number of inlets on the object, each of which would be
receiving a stream of data from some 'external' object. These would
be represented as variables in the chuck~ script, and whenever a
value of that variable was requested *during* the execution of the
script (see below, this is the problem) it would deliver the
currently-set value coming from the 'external' object. This isn't
hard to do, I've built other objects like this.

That's kind-of what I do now, variables can come into chuck~ as $1,
$2, etc. BUT:
when the script is sent to the chuck parser, those values get
'frozen' when the script executes. This is the problem -- I want to
be able to have a chuck~ variable (probably would have to be a ugen)
that will dynamically change as values come into the post-parser
executing script. I think MIDI and OSC in chuck possibly work this
way, but I'm not sure.

Could be -- how is chuck set up to respond to 'events' during script
execution? I'm missing something, I think. Although this is max-
oriented, I suspect that the pd chuck~ probably has a similar situation.
