I have a question. I bought a firewire audio/midi interface called Presonus Firebox. I am trying to set up my keyboard Korg M3 and the interface’s manual says I should plug active instruments on the “Line In” plugs only and not on the “instrument” plugs. The problem is I don’t know what an active instrument really is and also if all keyboards are active or passive instruments. How to know if an instrument is active or passive and if my Korg M3 is an “Active” instrument or a “Passive” one. I researched on the internet and I got all kinds of opposed answers such as “all keyboards are active” or Active instruments have a 9V battery somewhere etc….
I need some help here to get going…. Any idea is much appreciated.
I didn't find the right solution from the internet.
