    Description
    The Alesis S5 QuadraSynth Plus is a 76 key master keyboard with zones, velocity, aftertouch (doesn't say if it's channel or key) and release velocity. Two wheels, pitch and mod, but can be "completely programmable using the modulation matrix." The S5 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 S5 has 128 present and 128 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 S5 has an additional 128 preset and 128 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 supports optional Sound cards.
