In order to make Spark software work with SparkLe controller, you have to make sure your DAW (in your case Mixcraft) is not using SparkLE MIDI port.
That's what we call private port. I do not know how to disable midi port in Mixcraft but I will try to figure out how to.
To disable Spark internal sequencer, you have to click on the Host button in Spark toolbar.
To record into your DAW, you have to record from Spark plugin, not from the controller (see section 7.6.1 in Spark user's manual). Again we will download and install Mixcraft and try to figure out how to do that in your DAW.
More information soon.
