[sdiy] analog oscillators with non-standard waveforms

[jays at aracnet.com]

In a number of cases additional wave processors are built as seperate modules. To me I'd rather have a number of general modules or functions vs. having a bunch of specific modules.

Some examples would be:

* External pulse generators that can be fed with different waves. Most the time we make pulses from the saw waves. But try a triangle or sine wave.
* Bi-polar pulse generators.
* Wave folders or warpers that wrap, fold or warp waves. Here again triangle and saw waves can generate different results and timbre.
* Wave tables ran from internal hi-frequency oscillators or from a regular VCO.
* Wave shifters which take a standard single wave and shift them. When mixed with the original or multiple shifted waves they can give a much thicker sound. Sometimes like chorusing.
* Also just take multiple waveforms from a single oscillator, process them differently and mix them back together. Who says that we always have to have filters or processors after mixed oscillators? Why not before to thicken/warp/mangle/warm up the sound.

Have fun.
