This section gives you an easy-to-understand overview of the S90 ES — its wide range of sophisticated features, its MIDI
control and performance functions, and its convenient file management system for original data you’ve created with the
instrument.
Internal Structure (System Overview)
This synthesizer is made up of several blocks, as shown here.
Controller block
This block consists of the keyboard, Pitch Bend and Modulation Wheels, Control sliders, and so on.
The keyboard itself doesn’t generate sounds, but instead generates/transmits note on/off, velocity and other information
(MIDI messages) to the synthesizer’s tone generator block when you play notes. The controllers also generates/transmits
MIDI messages. The synthesizer’s tone generator block produces the sound according to the MIDI messages transmitted
from the keyboard and controllers.
