Topic: Recording for Dummy (me) - Recording from RCA Output to iPhone.

I am new to all of this but enjoying Pianoteq.  I want to make a video recording of the a performance employing Pianoteq.  Currently, I'm using a Windows 10 Laptop directly from a Roland HP704 digital piano.  Output from the laptop goes to a Topping D90SE DAC/Heaphone Amp.  I was hoping to run take the RCA output from the Preamp output of the Topping D90SE to a lightening cable that would input into the iPhone - but alas, the iPhone does not appear to recognize that input. 

What's the best strategy for doing all of this?  Appreciate your guidance.  I am not a recording engineer - just a geezer trying to make a recording of me playing Auld Lang Syne. 

Thanks!

You could record the song within Pianoteq and export it to either a wav file or a mp3.
No external gear needed.
