tclcsound.dylib is a tcl module, that needs to be loaded
with something like

load tclcsound.dylib Tclcsound

or package require

this is for people to load the tclcsound commands on
a tclsh or wish. If you are using cswish or cstclsh, the
commands are statically linked to the interpreter program.

I am not sure what you are doing exactly. However I am also
not sure exactly about paths for tcl modules.

a-ha, so that might be the problem! I have to have a look
at it myself. On my 10.3.9 old laptop, it works as you
described.

I think it is because the event function is executing
after the first call to csoundKsmps or csoundBuffer.
A solution for the above problem might be to declare the
ftables as blank tables (eg. f1 0 1024 7 0 1024 0) and
then re-initialise then as you need with csTable.

> Is this because csPlay explicitly looks to the score ?

No csPlay just sets a thread rolling with calls to
csoundKsmps
or csoundBuffer. But as I said it does not guarantee that
the ftable event call happens before it.

Thanks. I am actually quite pleased with the way this is
shaping up now. Today I tried my listener script with
pd and I can control cstclsh from it quite well (using
netsend). It might open up possibilities of client-server
csound set-ups with a variety of client programs (so far
I have a wish script and a PD patch, but it is possible
to write custom clients with a variety of languages).

That is an excellent idea, which also opens up the possibility of 
editing shared Csound files over a network through the use of a shared 
[textfile] object! I doubt that level of collaboration has yet been 
reached with Csound, yet it is now possible.

One thing I was having trouble with though was trying to get the 
canonical example GUI to respond to MIDI (or other) control data. What 
follows is an example; the sound reflects the change and responds to 
MIDI but the GUI does not. Registering the same invalue/outvalue 
chanels in MacCsound's GUI shows that the GUI responds. I think the 
Tclcsound idea would be amazing for implementing realtime performance 
systems where data is not passed to Csound from the TCL/Wish GUI but 
rather is just a display.
