I have tried to understand FM synthesis for some time. This is probably best FM synthesis tutorial I have seen. Maybe not the most informative but it has most inspiring examples. I have watched videos where guy certainly knows lot about theory of FM synthesis but he doesn’t show how to get most interesting sounds from it. This doesn’t concentrate on theory that much. It shows you how to get interesting sounds using FM synthesis.
I don’t have same synth he has but I will try to replicate these sounds with synths I have. I should be able to do that for the most parts. At least the ones I found most interesting. Just have to figure out how to do same things with different user interface.
