In Pro Tools, create an instrument track and a master track. Insert Spark as the RTAS plug in on insert A.
On your instrument input section, choose Spark 1 Channel 1. Below that labelled, Midi output selector, navigate to Predefined Spark controller, Spark public OUT.
Presuming you have correct Spark prefs set up to record Seq or Pads, or both. You can record like this. I have been unable to record midi from Spark any other way.
To monitor what you have just recorded change Midi output selector to Spark 1 Channel 1.
This is the only way I have been able to consistently record and monitor Spark in Pro Tools. If you can tell ne another way, I would be happy to hear it.
