Excellent course! For complimentary knowledge I also recommend you check out Bryan Spencer's "FM Synthesis 101" on here, especially the subject of "Sidebands" and the fascinating maths behind the ratio between the modulator and the carrier!
King Unique has a great relaxed teaching style and manages to pitch things at the right level and keeps even the driest technical stuff interesting. Enjoyed the course that much went out and bought FM8
Really nice and clear explaination. The only crique I have is that he uses operator which is exlusive for the 600$ version of ableton. I soemthing like dexed would have been better. However the only shown feature that that operator has that is not a feature on every other FM synth is that it has feedback on every operator regardless of the algorithm. I followed along wih the arturia DX7_V. Great course really learned a lot.
