Additive synthesis in the wavetable editor

[smaybius]

Additive synthesis (as in the Apple II's Mountain Computer musicsystem which uses 16 harmonics to create a wave) is probably really just wavetable synthesis but without a definite length. I'm suggesting this feature as a method of generating a wave as opposed to only drawing the wave or typing in numbers to each index. Or else, the user would need an external tool such as that one in PureBasic that both generates the waveform by the harmonics that are set and adjusts the harmonics by the waveform being modified by the mouse, and then the user would need to try to trace the generated waveform by hand and often have a noticeable difference in sound caused by inaccuracies in the replication.

This is already implemented in Furnace. When in the Wavetable Editor, first go to the Shapes tab. Then, click on "Amplitude/Phase"

As the name suggests, these sliders allow you to adjust the phase and amplitude of the currently selected wave-shape settings as well as frequency multiples of that shape up to 16. Note that the XOR Point is applied after the Additive synthesis and not before

You're welcome!

How does Furnace's wavetable features compare to Realfun 3, a SCC tracker? Here, here, and here. Kinda hard to use anything else once you get used to it.

I'm guessing you mean a wave macro, hot-swapping between different chosen waves at a variable rate

@bryc Furnace is definitely capable of producing these waveforms, but it might take some time to do so, depending on how you go about it. I don't know how Realfun 3 implements its wavetable editing/synthesizing, but Furnace does have tools to create wavetables with Additive synthesis and FM. It also allows for some of these layered sounds you indicated, namely with its chorusing, mixed chorusing, and Phase Modulation modes. Additionally, I believe Furnace also allows you to pull wavetables from any audio recording, using its sample editor; however, I am very unfamiliar with this feature.

The nice thing about Furnace is that if there are any features that you find lacking from its software, you can simply make a suggestion to the developer himself, either via these Discussions or via Discord, which tends to get more attention/discussion in my experience.
