Spark/Spark 2/iSpark is software only.
The hardware is just a MIDI controller especially made for Spark (the software) which can also be used with other MIDI products (I use the SparkLE controller with Reason, as an example).
I was referring to the hardware. I wanted to know if the unit was able to receive midi notes from the DAW, and feed them into the units sequencer.
The main thing (and confusion) here is that: There's no built-in sequencer in the Spark/Spark LE hardware.
So, you can play/control Spark (software) with your DAW and/or any MIDI controller, including one with keys, since the pads/sounds are MIDI Note+Velocity triggered.
