All sound on this tracks use triangle wave (with VCO module in modular patch)
to make rhytmic & drone music composition (I choose triangle wave as sound
source to create experiment with. Challenging and limiting in produce a sound
experiment / music composition by applying only one sound source, push the
limit of creativity and sound design skill.)
A triangle wave sounds rather brassy.
The random wave sounds like white noise.
A sound with a regular pattern has a fundamental frequency which is the number
of peaks in the waveform per second.
A triangle wave is a non-sinusoidal waveform named for its triangular shape.
It is a periodic, piecewise linear, continuous real function.
Like a square wave, the triangle wave contains only odd harmonics.
However, the higher harmonics roll off much faster than in a square wave
(proportional to the inverse square of the harmonic number as opposed to just
the inverse).
