Currently I have created a software instrument for Spark in Luna, which will monitor fine. I get actual audio and can see the meter moving within the transport. When I hit record I get the red box as if it's ready to record midi but nothing shows up from the sequencer. If I start to mess with my keyboard (Keylab 49 MKII) it DOES record that midi data.
I couldn't find anything in the Midi Control center to address the Spark plugin midi data since it seems to be an application for actual hardware. I did fiddle around in the Spark prefs and found and option for "Send midi from sequencer" which I clicked and it is clicked but also says "####WOULD USE "IAC Driver Spark1 Midi OUT" BUT THE PORT DOESN'T EXIST ####" So either this could be the root of the problem, or, I'm still missing something obvious.
