In reply to Tudor Timi:
It is highly recommended to NOT use p_sequencers. The main reason is that it requires you to create a specific sequencer type, which normally isn’t needed. It also requires that a specific sequencer of that type exist in your environment, which limits re-usability.
By not using p_sequencer, your sequence can run on any sequencer that is type-compatible and is therefor inherently more re-usable.
