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