Alright. The process is really very simple. I used the two function generators that I posted a photo of earlier in this thread. The top one modulating the frequency of the lower one. The main part of the piece consists of about 10 takes of drones. Each take features different levels of of fm modulation, various overtones being accentuated, slight variations in frequency with each take to make the takes beat against one another. An explorative process, adjusting as I record. I think my record channel features the use of Michael Norris’ binshift plugin as well, highest fft size, only binshifted very slightly. At this setting, where it hardly manipulates the sound, it just seems to push the phase around to give it a very slight sense of movement, otherwise each take becomes a tad too static. At least for what I was going for with this piece.
The fm-capable function generator has a seperate dc amplifier built in as well, which can be overdriven, though it’s a mostly unappealing overdrive. I would find a setting very close to it being overdriven to just slightly bring out some more overtones, which, when layered 10 times, is probably what resulted in the rich top-end texture, which I accentuated even more when mixing. That’s about as insightful as I can be right now. All the best.
