Owner`s manual

A brief explanation of the MC-505Õs internal organiza-
tion was provided in the Quick Start manual, but this
chapter contains a more detailed explanation of the
basic sections: the controller section, sound generat-
ing section, and the sequencer section.
How the MC-505 Is Organized
fig.1-3
Controller
On the MC-505, the controller section includes the
keyboard pads, the panel knobs and sliders, the D
Beam controller, and a pedal switch connected to the
rear panel. By operating these controllers, you can
play or modify sounds.
Sound Generator
This is the section that produces the sound. The
sound generator produces sound in response to data
it receives from the MC-505Õs controllers and its
sequencer. It can also be played by MIDI messages
that arrive from an external MIDI device.
Sequencer
The sequencer section records controller operations
(knob movements) as MIDI messages, and can play
back the MIDI messages that were recorded. MIDI
messages that have been recorded on the sequencer
can also be transmitted from the MIDI OUT connec-
tor, and used to control external MIDI devices.
About the Sound Generator
Tones and Patches
ÒTonesÓ are the smallest unit of sound used by the
MC-505, and one tone produces one sound. Up to
four of these tones can be combined to create a
Òpatch,Ó which is a single sound that you play. There
are two types of patches: ÒPreset PatchesÓ which are
already built into the MC-505, and ÒUser PatchesÓ
which are the patches that you create.
Tones and patches are organized as illustrated below.
fig.1-4
* The way in which the four tones are combined will deter-
mine how they will sound. This is determined by the
Structure Type parameter.

Played (Common)Ó (p. 54)
