Ableton Live - Architecture and Interface

CHAPTER 23. LIVE INSTRUMENT REFERENCE 352
Analog is a virtual analog synthesizer, created in collaboration with Applied Acoustics Sys-
tems. With this instrument, we have not attempted to emulate a specic vintage analog
synthesizer but rather to combine different features of legendary vintage synthesizers into
a modern instrument. Analog generates sound by simulating the different components of
the synthesizer through physical modeling. This technology uses the laws of physics to
reproduce how an object or system produces sound. In the case of Analog, mathematical
equations describing how analog circuits function are solved in real time. Analog uses no
sampling or wavetables; the sound is simply calculated in real time by the CPU according
to the values of each parameter. This sound synthesis method ensures unmatched sound
quality, realism, war mth and playing dynamics.
The full version of Analog is not included with the standard version of Live, but is a special
feature available for purchase separately.
