Playing drums and keyboard simultaneously

Hi all! I have a Roland 25kv with a usb midi cable and a Korg Microsynth input through a Komplete Audio 6. My question is can I play the Korg through a synth VST while the Roland is on a separate VST drum kit? I tried creating two instrument channels but only one will play at a time.

Yes, you need to set MIDI inputs separately and put both tracks in Listen mode or select them both.
