[Csnd] Orch/sco MACRO?

Subject[Csnd] Orch/sco MACRO?
Is it possible to define a macro that works in both the orc and sco?

I want to define total duration and use that macro value in both places, as 
well as to define the macro toward the beginning of the .csd:

in header:
define DUR #360# ; overall duration

in an instrument:
instr 1
linseg 0, .5, $DUR -1, .5, 0

in score:
i1 0 $DUR

(If this is possible, some reference should be made to it in the manual. As 
it is, the docs seem to suggest it doesn't work.)

You could always define the macro in the score, then pass it to a global
setup instrument (at time 0) in a p-field, then assign the value in that
p-field to a global i-rate value called giDur, then use giDur in any
instrument. It's roundabout, but not cumbersome, and it ought to work.

To answer your specific question ... I don't know.

Sorry if this seems like too basic of an answer, but is copy/pasting your macro definitions from the orc to the sco something you're trying to avoid?

This seems to be working:

<CsoundSynthesizer>

<CsOptions>

</CsOptions>

<CsInstruments>

#define MACRO #440#

instr 1

a1 oscil 10000, $MACRO, 1

out a1

endin

instr 2

a1 oscil 10000, p4, 1

out a1

endin

</CsInstruments>

<CsScore>
#define MACRO #440#

f1 0 4096 10 1

i1 0 1

i2 2 1 $MACRO

</CsScore>

</CsoundSynthesizer>


Best,

Colman

Aimple answer is no as the two languages are separate.
Longer answer is that both languages accept #include nd both have the same
macro syntax, so place in a file and include in each place.  Then u pnly
have to maintain one file
