Casio CT-S1, CT-S1-76, CT-S1-76WE - MIDI Controller Manual

Overview

Product Configuration as a MIDI Device

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

System Section
The System Section manages the Instrument status and user data.

Performance Controller Section
The Performance Controller Section performs keyboard play and controller operations, and generates performance messages. 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 MIDI setting. For details about the MIDI setting, see the Instrument's User's Guide.

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.

1. Sound Generator Common Block
   The common block consists of system effects, master control, etc. These can be controlled by effect function, general universal system exclusive messages, or the Instrument's system exclusive messages or all. There are two types of system effects on this instrument: system effects applied to keyboard playing parts and system effects applied to other parts.
2. Instrument Part Block
   The instrument part section is devided into A, B, C group for every 16 parts, and it consists of a total of 48 parts. The settings of each part can be changed using channel messages or Instrument's system exclusive messages or all. Of these, only the C group channels can be controlled by external channel messages.

The functions assigned to each part are shown below.

Pan (0AH)

Note1: For information about the relationship between setting values and send/receive values, see "Pan Setting Value Table" in "Setting Values and Send/Receive Values".

Receive Receipt changes the pan of the corresponding part.

Expression Controller (0BH)

Receive Receipt changes the expression value.

Damper pedal (sustain) (40H)

Transmit Sent when a pedal that has a sustain function is operated.

Receive Receipt performs an operation equivalent to a sustain pedal operation.

Timbre Type Specific Operation This operation differs in accordance with the Timbre Type (see "About the Timbre Type" ) setting.

see "Sustain Pedal Setting Value Table" in "Setting Values and Send/Receive Values."

• Melody
  Sustain off/on control is performed in accordance with the value of the received message. For information about the relationship between setting values and send/receive values, see the " Off/On Setting Value Table" in "Setting Values and Send/Receive Values".
• Drum
  The received message does not affect sound source operation.

Receive Receipt changes the filter resonance intensity.

Release Time (48H)

Note1: For information about the relationship between setting values and send/receive values, see the "-64 - 0 - +63 Setting Value Table" in "Setting Values and Send/Receive Values" of this document.

Transmit Sent when the sustain function is used.

Receive Receipt makes a relative change in the time it takes for a note to decay to zero after a key is released.

Attack Time (49H)

Note1: For information about the relationship between setting values and send/receive values, see the " –64 - 0 - +63 Setting Value Table" in "Setting Values and Send/Receive Values" of this document.

Receive Receipt makes a relative change in the time it takes for a note to rise to its maximum level.

Portamento Control (54H)

Receive Receipt of this message first stores the Source Note Number for the next note. When the next Note On is received, the portamento effect is applied to the note using this Source Note Number as the pitch start point and the Note On event key number as the end point. If there already is a note being sounded by Source Note Number at this time, the new note on is not performed and the portamento effect is applied to the pitch of the note being sounded. That is to say that legato play is performed.

Transmit Sent when a tone number is selected. Also, sent when the Program number send function is used.

Receive Receipt changes the tone of the corresponding part. The selected tone is determined by the program value of this message and the Bank Select message value received prior to this message. Also note that receipt of this message also may change the Timbre Type that corresponds to the selected tone. For more information, see "About the Timbre Type" below.

Channel Pressure (Aftertouch)

Receive Receipt adds, to the tone being sounded, modulation of a depth specified by the value. In the case of a tone that already has modulation applied, receipt of this message increases the modulation depth. The modulation effect differs according to the tone being used.

Pitch Bend Change

Receive Receipt changes the pitch of the currently sounding note. The range of the pitch change depends on the Pitch Bend Sensitivity value setting in RPN. For information about the Pitch Bend Sensitivity, see the "Pitch Bend Sensitivitys" of this document.

MIDI Implementation Notation

Value Notation

Hexadecimal Notation
MIDI implementation sometimes requires that data be expressed in hexadecimal format. Hexadecimal values are indicated by the letter "H" after the value. The hexadecimal equivalents of decimal values 10 through 15 are expressed as the letters A through F.

The table below shows the hexadecimal equivalents for decimal values 0 through 127, which are often used in MIDI messages.
