![]() just always curious as to how these things work. Any ideas on this? Anyways, I'm satisfied that the scaling is correct and I'm happy to go with this. You can see that the spectrum just looks fuzzier, I dont know if my knowledge of PM/FM is failing me and I'm missing something here or if I can just put this down to some "special sauce" that Native Instruments has cooked up behind the scenes? Some extra DSP magic? Even comparing a straight up sine tone the fm8 sine has some crazy frequencies going on at the top end. I got a spectrum analyser to look at them and this is what I found.įor the test, I basically had my pd patch and fm8 running into ableton: both had 1 sine tone modulating another at a ratio of 2 with the mod index (or operator output in fm8 case) at full. Heres how to Import DX7 patches into FM8. ![]() It's not that the mod index isn't right because it sounds pretty bang on but the fm8 sounds more filled out with high frequencies. A DX7 patch by Michael Brook (Eno/Lanois) In the 80s and 90s Brian Enos label Opal had a regular newsletter. The problem I'm having now, is that when I try different ways of calculating mod index (according to the sources I've linked above) is that although they are all in the right ballpark, none of them are generating the same amount of harmonics as the fm8. This totally helped me out and I'm now definitely in the right area.
