1 Introduction
Strum Acoustic Session GS-1 is a synthesizer dedicated to the emulation of acoustic guitars. This
special edition is a simplified version of Strum Acoustic GS-1. The synthesizer is entirely based on
the A|A|S physical modeling technology and uses no sampling nor wave tables. Instead it produces
sound by solving, on the fly, mathematical equations modeling the different components of a guitar
and how they interact. This elaborate synthesis engine responds dynamically to the control signals
it receives while you play thereby reproducing the richness and responsiveness of real instruments.
Strum Acoustic Session features elaborate modeling of the vibrations of the strings, pick or
finger action and the body of the guitar. Strum Acoustic Session also includes many functionalities
which make it easy to reproduce the playing techniques of a guitarist on a keyboard. Strum Acoustic
Session includes a chord detection module and performs automatic voicing of chords. In other
words, you play the chords you know on the keyboard and Strum will voice them automatically, for
different musical styles, as a guitarist would have played them. The picking-hand technique of a
guitarist is reproduced by an auto-strum function, special strumming keys or using standard MIDI
loops.
Before discussing the synthesizer in more detail, we would like to take this opportunity to thank
you for choosing an A|A|S product. We sincerely hope that this product will bring you inspiration,
pleasure and fulfill your creative needs.
