Script to trigger 2nd group when same zone played twice in a row

benjaminfrog

Rather than set up a round robin that alternates between two groups with every note event, I'm trying to write a script that only triggers the 2nd group when the same zone is played twice in a row. Unfortunately, the results I'm getting are that of a standard round robin. Can anyone tell me where I'm going wrong?

on init

  declare $last_zone

  declare $last_group

end on

on note

disallow_group($ALL_GROUPS)

  if (($last_zone = get_event_par($EVENT_ID,$EVENT_PAR_ZONE_ID)) and ($last_group = 0))

    allow_group(1)  

    $last_group := 1

  else 

    allow_group(0)

    $last_group := 0

  end if

  $last_zone := get_event_par($EVENT_ID,$EVENT_PAR_ZONE_ID)

end on

To GET the zone ID from the event, you need to wait(1) ... ie. retrieve the zone ID after the EVENT begins, so you can't use this method to choose which group/robin plays, because you get the information too late.

If you collect all the zone IDs in advance, and store them in an array, then you could look them up instantly and use that to control the group/robin choice. This is indeed a method I've used and seen others use..

I assume there are actually more than 2 groups in your instrument, because you don't really need this level of detail for just two possibilites. ie. you could just store whether group 0 or 1 was played last for each key in an Array[$EVENT_NOTE]
