Is there a way to code a live loop so it syncs to another loop only on the first time through?  
I’m thinking of doing some experiments in polymeters – different numbers of beats in each loop, but the duration of a single beat is the same across the board.  
So I want them to start together, but not resync after the first time through.  
Thanks!

Hello!  
quite not understand what are you trying to achieve, but to answer:

Is there a way to code a live loop so it syncs to another loop only on the first time through?

R// yes, example:

```ruby
counter = 0

live_loop :loop_one do
  play 60
  if counter == 1 then
    cue :test
  end
  counter+= 1
  print counter
  
  sleep 1
end

live_loop :loop_two, sync: :test do
  play 80
  sleep 0.9
end

```

to make them sound “out of sync” you will need to play with the sleep time.

does that answer what are you trying to achieve?

Yes, that would do it. Thanks!

No need for the counter and the cue, this will do the same (sync as a live\_loop argument only syncs once at startup):

```ruby
live_loop :loop_one do
  play 60  
  sleep 1
end

live_loop :loop_two, sync: :loop_one do
  play 80
  sleep 0.9
end

```

I did not realize that. That’s exactly what I need.  
Thanks!
