The Power of FM/PM, Workshop 3 is online.
https://youtu.be/VFmCP54OB_k
After a short “column 1” with the rest of the functions of DEXED, this workshop 3 deals with a lot of “practical FM-theory” stuff, like changes of pitch and fundamental, special sounds, refining the system of C:M ratios etc. The third columns is dedicated to Brian Eno and one of his violin DX7 patches from 1987. A detailed analyse of the patch leads – hopefully – to experiments of your own. See the timeline for more details.
Have a great day and a good time!
