Hello to everyone who is familar with FM synthesis,
here is an very interesting question I have:
I experement with one OP stack with two operators. One is modeling the other as a carrier. I use in Montage algorithm 7, there the OP 1 is modeling OP 2. The others are muted.
OP 2 uses Sine wave and the Freq MOde is Ratio. The Output level is 99. Coarse is set to 1.
OP 1 who models OP 2 is set to output level 99 too. Freq Mode is fixed.
Coarse starting with 1. I used Sine wave too as in OP 2 If I change Coarse higher and higher first I here the vibrato thing. This I understand.
But at higher frequencys something that surprise me.
I here with my ears two freqencys.
Following happend when play the keys from left to right the deeper frequency goes first higher and higher. The upper frequency is falling down. Somtimes the cros against and than they change the directiona I hope I describe this right.
Why does this happen?
Thanks for answer.
