we find one of the characteristics that contributed to the typical sound of vintage
synthesizers.
TAE reproduces the instability of oscillators, bringing a fatter and “bigger” sound.
1.2.3 A better reproduction of analog filters
TAE allows more precise emulation of analog filters than standard digital filters. To obtain this
result, the TAE technology is based on the analysis of the analog circuits to be reproduced,
and converts them into algorithms that faithfully mimic the characteristics of the original
filters. The curve underneath shows the comparison of the original ARP2600 filter and that of
the ARP2600 V.

1.2.4 Ring modulator
The ARP2600 V includes a ring modulator, just like the original ARP2600. The ring modulator
allows the application of a waveform (a sinusoid) to another, in order to transform it. The
result is a more brilliant sound, distorted, and enriched in harmonics. As a result of this
increase in the number of harmonics, standard ring modulation algorithms create an audible
aliasing. To avoid this unwanted effect, TAE includes a module for the dynamic control of the
amplitude with aliasing correction, which removes every trace of aliasing in the signal coming
from the ring modulator.
