# Alesis S4 QuadraSynth Sound Module

The Alesis S4 QuadraSynth is a 64 voice, rackmount MIDI sound module featuring
built-in parallel-matrix digital signal processing.  The 64 (sic, probably S4)
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" (dividing
polyphony by four in the process???? Eirikur) each with their own set of 3
envelope generators, 3 LPO's (sic), tracking generator, dynamic low pass
filter, and very comprehensive modulation matrix.  In the "Program Mode," teh
S4 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 S4 has an additional 128 preset and 128 user programmable "Mixes" which can
be used for multi-timbral sequencing applications.  In this mode, differnt
programs may be assigned to each of the 16 MIDI channels simultaneously, and
eve (sic) 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 Rom (sic) cards.  Has OPTICAL
OUTPUT, (mentioned in the S5 paragraph, summarized below).

Projected Ship Date: Third Quarter 1992
Projected Suggested US Retail Price: $995

# Alesis S5 QuadraSynth Master Keyboard

Same synth engine with a larger display in 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."  Both S4 and S5 have digital optical outputs and can go
directly to ADAT without leaving the digital domain.

Projected Ship Date: Third Quarter 1992
Projected Suggested US Retail Price: $1495
