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 Factory 2.5. They are both equally deformed by the low-pass and
high—pass filtering.
