Thanks very much for investigating all this. I’m super interested in Neóni, and feel much closer now to understanding what makes its behavior unique (as well as learning more about other oscillators).
Any particular reason for not including Fundamental WT VCO alongside those other four?
Here’s a look at some of the testing I’ve been doing with Neóni. I have each group present in two forms, and those two forms are plotted against eachother on each Bogaudio Analyzer XL:
- C4 Osc → FM C3 Osc
- (C5 Osc + C4 Osc) → FM C3 Osc
In other words, the spectrogram is showing the difference created by the addition of a C5 oscillator.
In both groups, the C3 Osc serves as the sync source for the other oscillator(s).
These are the oscillators (I aimed for including all linear through-zero true-FM oscillators with sync):
- Terrorform (True FM mode)
- Fundamental WT VCO (LFM mode)
- Neóni (all oscillators Traditional mode)
- Neóni (C3 Osc in T.Z. mode, all others Traditional mode)
In the 3-oscillator-algorithms, the sync has this effect visible in Hot Tuna:
- Terrorform throws Hot Tuna off its tracks
- Fundamental shifts to a solid E3
- Neóni leaves Hot Tuna mostly unperturbed
