ARTURIA – JUPITER-8V – USER’S MANUAL
12
It was the introduction of COSM and the “V” products in 1995 that set the future
direction for Roland. Mr. Kakehashi and his teams had recognized that digital signal
processing and physical modeling were the future of the electronic audio industry. Roland
applied these technologies to a broad range of products. From sound modules and dance-
oriented groove boxes to their most expensive digital mixers and audio workstations,
Roland remains at the forefront of synthesizers and electronic music.
1.2 TAE
®
TAE® - True Analog Emulation - is Arturia's outstanding technology dedicated to the
digital reproduction of analog circuits used in classic analog synthesizers.
The Jupiter-8V benefits from an enhanced version of TAE®, optimizing CPU allocation
and memory usage, while being even more accurate than in previous products.
When implemented in software code, TAE®’s algorithms guarantee authentic emulation
of hardware specifications. This is why the Jupiter-8V, and all of Arturia’s virtual
synthesizers, offer an unparalleled quality of sound.
TAE® combines four major advances in the domain of synthesis:
1.2.1 Aliasing-free oscillators
Standard digital synthesizers produce aliasing in high frequencies, and also when using
Pulse Width Modulation or FM.
TAE® allows the production of totally aliasing-free oscillators in all contexts (PWM, FM…),
and at no extra CPU cost.

1.2.2 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® allows the reproduction of this capacitor discharge. This is the analysis of the
