and yes, i know what you mean with Rhodes and Koto :)
last sample song i made
this was all samples
nvm u know how lol
The only thing that I would recommend is playing your own notes, you dont need to know how to play piano just double click and edit the track you placed get an instrument (Koto 32 in Fm Synth or Rhoades in GM-2 are my favorites) and place a couple of notes its pretty easy and if u need you can always use the cords pack built in soundation and add a couple notes to that.
Pretty Good Bro!!!
