Description
The Alesis S4 Plus QuadraSynth is a 64 voice, rackmount MIDI sound module featuring built-in parallel-matrix digital signal processing. The 64 has a large, easy-to-read, back-lit LCD display for "Composite Synthesis," which is an innovative combination of subtractive and additive synthesis.

Each program can be made up of as many as four individual "sounds" each with their own set of 3 envelope generators, 3 LFO's, tracking generator, dynamic low pass filter, and very comprehensive modulation matrix.

In the "Program Mode," the S4 Plus has 128 present and 640 user programs in which the user can program up to 7 simultaneous effects which can be independently assigned to any of four effect busses. This allows different programs or composite sounds to be routed to different effects with dynamically controllable amounts.

In the "Mix Mode," the S4 Plus has an additional 100 preset and 500 user programmable "Mixes" which can be used for multi-timbral sequencing applications. In this mode, different programs may be assigned to each of the 16 MIDI channels simultaneously, and have allows you to have separate discrete effects on different sounds with complete mix control. That's why we call it "Mix Mode" rather than a simple multipatch.

Programs may be routed to any of the four audio output jacks on the back and the S4 Plus supports optional Sound cards.
