1.3.2 A better reproduction of analog oscillator waveforms
The waveforms produced by the oscillators in analog synthesizers are marked by the
presence of a capacitor in the circuits. The discharge of the capacitor results in a light
bend in the original waveform (notably for saw tooth, triangular and square waveforms).
TAE
®
reproduces the result of this capacitor discharge in software. This is the analysis of
a waveform from one of the 5 original instruments that Arturia’s software emulates,
followed by one made by Analog Laboratory. They are both equally deformed by the low-
pass and high-pass filtering.
