Is there a way to fire multiple clips at the same time using Javascript with the LiveAPI?

I've tried firing some clips inside a 'for' iterator but sometimes they fire separately. For example, the following code:
var api = new LiveAPI();
for (var i = 0; i < 5; i++) {
api.path = "live_set tracks " + i + " clip_slots " + 0;
api.call("fire"); // Sometimes this is slow and clips are not fired at once. Find another way!
}

This happens specially when transport is stopped. I guess that in the first iteration, when the first clip is fired, it causes the transport to start playing and after that, the next iterations fire the clips and wait for the next quantization.

Is there any way to call the 'fire' method and passing a list of clips in a single call?

Anyone knows a workaround for this?

workaround would be to not stop the transport, but stop the clips instead.

then when you need to trigger the clips you trigger them sequentially, then set the transport to the beginning and you'll have the sync.

mmh, thanks for your idea but cannot use in my case because I want to trigger the clips to start a recording..

You could start transport with an API call and afterwards trigger the clips sequentially.
Then all clips will start in sync at the next quantization point.

That would be a workaround but then clips would be recorded with a 1-bar offset (or the quantization setting) in relation to the other clips that started playing along with the transport.

Any hope for improvements in LiveAPI for the upcoming 9.1?
