CT-S195 MIDI Implementation for Casiotone Keyboard

MIDI Message Overview

Product Configuration as a MIDI Device

As a MIDI device, this Instrument consists of the Performance Controller Section and Sound Generator Section described below. Each of these sections can send and receive specificMIDIMessages in accordance with its function.

Performance Controller Section

The Performance Controller Section performs keyboard play and controller operations, and generates performance messages in accordance with auto play, etc. Basically, generated performance messages are sent to external destinations while also being transmitted to the Sound Generator Section. The channel number of the sent channel message is in accordance with the Instrument’s instrument part number. MIDI Output Performance Information The following describes the performance information that is output and is not output as MIDI signals.

• Output performance
  • Keyboard play and controller operations by the musician
• Non-output performance
  • Demo Songs
  • Song playback
  • Auto accompaniment
  • Dance Music Mode playback
  • Lesson function (LK-S250 only)

Sound Generator Section

The Sound Generator Section mainly performs receive of performance information and sound source setting information. It consists of a common part that does not depend on the channel and a musical instrument part that is independent of each channel.

Sound Generator Common Block

The common block consists of system effects, mixer master control, etc. A number of the parameters of these items can be controlled by universal system exclusive messages.

Instrument Part Block

The instrument part section consists of a total of 32 instrument parts, divided into two groups, named Group A and Group B of 16 instruments each. Each part can perform operations and setting changes using channel messages. Only Group B can be controlled by external channel messages. As shown in the following table, there is a fixed relationship between channel message receive channel numbers and instrument parts.

Timbre Type Specific Operation

The sound source operation performed for a sound generator instrument receive message may depend on the value of the Timbre Type (see “About the Timbre Type” in “10 Program Change”) of each part’s operation mode. For details, see the explanation for each message.

Conditions that Disable Message Send and Receive

The main conditions whenMIDI message send and receive are disabled by the Instrument are thosedescribed below.

• While the instrument is accessing flash memory.

Channel Message

Receive Channel

• The channel number of the channel message received by each part is shown in the table under “1.2.2 Instrument Part Block”.
