Here is an FM Tutorial for Spectrasonics Omnisphere 2.4. I cover using FM with Harmonia and using the Mod ENv for a 4 operator fm synth inside Omnisphere. Enjoy and hope you learn something. Sorry for the audio quality. MP4's are a pain to try and split the audio. I use OBS a free screen recorder. Next time it will be better. I will have to record directly in FL Studio to be able to split the audio and only my voice might be a little odd. Also, had a tv and AC right behind me going. So, any De-Noiser would have issues with that and it's loud LOL.
