PC3: Subharmonic and Harmonic Series Additive Synth Starting Points

For the PC3, I made a Program with a series of +sines (2 per layer) tuned to a fundamental plus the first 15 partials of the subharmonic series. It's a weird tone, and perhaps not useful for more than creating artificial sounding cymbals, gongs, or wind-chimes. However, with different balances of tones and envelopes, you might be able to make some unique bass sounds, and space ship sounds.

I also included a program that is 16 tones of the harmonic series-- with the same structure. Sounds goofy. 

A third program merges the two for a very complex tone.

The idea would be that by varying the level and envelope of the layers, you might be able to make some unique tones that might be similar to a wavetable in personality.

Interesting idea.  I've always liked additive stuff.  It loaded into my PC4 after unzipping it.

By messing around with some of the layer volumes and transpose settings, I came up with some stuff that's almost usable.  ? 

Of course, dealing with additive stuff is fiddly, and if I worked on some envelopes for all the partials, it could probably start to sound pretty good.

It's a nice starting point template though - thanks.

Exactly, wildbill. It's fiddly, and only marginally useful. But yea, my goal was just to get a reasonable starting point, and hopefully someone else would make something "almost" usable.

Pitched way up, it's kind of surprising how the subharmonic tones have that cymbal like tone.

As you say, if one messed with the envelopes (unfortunately, 2 at a time) one could make some interesting attack, decay, and sustain aspects.
