after i had three weeks of fun using the presets of my new MODX6 and building first own performances, yesterday for the first time i spent some time with the FM-X engine of my MODX6, starting from the init performance and trying some fundamental things. Unfortunately, i discovered a surprising (not nice) effect: Even when i play with only one oscillator simply producing a sine wave (all other oscillators/modulators are at zero volume), strong clicking noise and distortions are induced when several notes are played simultaneouly. The effect, which seems to be an overdrive problem, is getting stronger the loader the signal is. For the algorithm with 8 oscillators (No. 1) about 6 notes have to be played simultaneously to start the clicking noise, for algorithms with less oscillators (e.g. No. 37 with 3 oscillators) it starts with 4 simultaneously played notes. When i add the second oscillator with the same (not detuned) sine wave, very strong distortion arises even when a second note is played at the same time. Tuning down the volume of the part seems to help a little bit, but can not remove the effect. Tuning down other volumes (perfomance, master volume) don't lead to an improvement. Has anyone also discovered this effect? Is this a malfunction of my MODX6?
Thanks for your answers !
