I have a metronome triggering instrument (2) that worked when I had 'alwayson 2' in the header.
Now I want to turn instr 2 on and off depending on a channel, like so:

; turn metro on/off
gkmetronoff  chnget "metronoff"
ktrig2 changed gkmetronoff
 if ktrig2 == 1 then
    ;printk2 ktrig2
    turnon 2
 else
    ;printk2 ktrig2
    turnoff2 2,0,1
 endif
endin

but the metronome stays silent even though ktrig2 gets a value of 1, so turnon 2 should do it.
I have uncommented the alwayson 2 in the header, still I see 'new alloc for instr 2:' when I start the csd.
That should not happen untill the metronoff channel gets a 1....

turnon is made for init-time:
   turnon insnum [, itime]

i suppose when you use the event opcode it should work.

perhaps you need to change your if-condition like this, too:

if ktrig2 == 1 then
  if gkmetronoff == 1 then
   event "i", ...
  else
   turnoff2 ...
  endif
endif

Event only works if I have the turnoff2 commented out. Apparently first 
the else is executed (gkmetronoff = 0), turning instr 2 off,
but then it won't turn on again with the event "i"...

can you send a (perhaps reduced) csd which shows the problem?

Ok, this is starting to work, thanks. I use 2 channels now, to turn the metronome on and off, like so:

; turn metro on/off
gkmetroon  chnget "metroon"
gkmetroff  chnget "metroff"
ktrig2 changed gkmetroon
if ktrig2 == 1 then
   event     "i", 2, 0, -1
endif

ktrig3 changed gkmetroff
if ktrig3 == 1 then
   turnoff2 2,0,1
endif
endin

turnoff2 runs at k-rate. The else is getting executed every kcycle except when 'changed' flicks ktrig2 to 1 for a single kcycle only. So 'event' doesn't get much of a chance to work, because in the very next kcycle turnoff2 switches it off.

Hi,

If you can leave the metronome instrument always running, then perhaps one solution with lesser lines could be:

gkmetronoff chnget "metronoff"

ktrig = metro(krate) * gkmetronoff

Greetings,

tarmo
