Controller DDJ-400 + iPad lightning port, breakout HDMI + USB for controller for Video Djay + Controller connect??

If using a controller (like my Pioneer DDJ-400) with iPad and doing video Djay also (video/picture show sync with music), how do I connect both controller to iPad and video output from iPad to HDMI cable at same time? I’m using iPad 2nd generation with Lightning port. I prefer _NOT_ to use Apple AirPlay to send video from Djay to projector screen, and introduce that wireless connection for stability reasons, I prefer to keep everything physically connected. So far I can only find the Apple “USB-C Digital AV Multiport Adapter” that converts from USB-C to combination of HDMI + USB ports…however, only Newest iPad Pro have USB-C port, all other iPad use Lightning…

Please help me figure out how to physically connect all this to my iPad using Lightning port!!
