You shouldn't need to do anything. A score event normally terminates a note 
at the end of p3; a MIDI note terminates at MIDI off. In either case, an "r" 
envelope simply extends note duration (prior to "off") by the length of the 
release segment.

…now the last step that should be solved is:
do so when kenv goes to 0 the instrument is turned off (turnoff)

…

e

this instrument is called (Called), in turn, by another (call) instrument
that contains schedkwhen (with kdur = 86400);

why would that the instrument is turned off and check that it really
happened…

If i'm not wrong You can use a negative p1, i.e send messages to instr 1 with
i-1,
or, maybe better, You can use turnoff2, that send a turn off message to
another instrument.

Hope i'm right...

... and active opcode return the number of instances of an instrument,
i.e if instrument is off, i suppose return 0.

;this is the relevant passage of the code:

;=======================
instr 1 ; call

		schedkwhen	gktrigger, -1, 1, 2, 0, 86400		; call

endin
 
;=======================

instr 2 ; called

if	gktrigger	== 0 then
; xtratim	.5 (?)
itime		=	1
kenv	 linsegr	1, p3, 1, itime, 0
turnoff

elseif	gktrigger	!= 0 then
kenv	linen 1, .5, p3, .5
endif

a1		diskin	"called.wav", 1
;a1 		oscili 1, 600, 1
		out		a1*kenv

		endin
