I am not familiar with any of your hardware or software so I may be way off base here. It sounds like you are recording on the same MIDI channel and track.
1-Set FL up to record one track with MIDI channel one and using your keyboard to play your part with the keyboard sending out data one MIDI channel one.
2-Set another/different FL track to record using MIDI channel 10 and your keyboard sending out drum data on MIDI channel 10.
In other words you must match your sending and receiving MIDI channels every time you record.
I hope this helps and good luck..
Hi MarioD
I tried to look for a free or cheapest 16 midi track software recorder for my (Windows 7) computer. No Luck there. There was no vst (to find online) for my FL studio that would solve this record 16 midi channel problem.
Some documentation I read said you can't record 16 midi channels on 16 midi tracks simultaneously.
