Receipt of this message changes the tone of the part that corresponds to the MIDI channel.
The selected tone is determined by the program value of this message and the Bank Select message value received prior
to this message. See the Tone List in the Instrument's User's Guide for information about actually selecting tones, etc.
Also note that receipt of this message may also change the Timbre Type parameter at the same time. For more information,
see "11.1 About the Timbre Type" below.
11.1 About the Timbre Type
The tone selected by each part of this Instrument has a "Timbre Type" parameter that specifies the type of sound source
for the tone. As explained under "21.1 Basic Parameters", there are three Timbre Type settings: Melody, Piano, and Drum.
The following explains how each of these operates.
• Timbre Type: Melody
This timbre type optimizes for normal melody tones. It performs damper pedal on/off operation.
• Timbre Type: Piano
This setting optimizes for piano tones. The decay rate of the voice being sounded and Acoustic Resonance effect
characteristics are continually altered in accordance with the damper pedal position.
• Timbre Type: Drum
This setting optimizes for drum sounds. The damper pedal does not function.
11.2 DSP Assignments During Tone Selection
11.2.1 DSP Line Structure
Though the Instrument has four DSP lines that can be used simultaneously, selecting a tone that uses DSP causes the required
number of DSP lines to become reserved so the tone is configured with the requisite DSP.
Tones listed under "23.1 Monaural Tone DSP" use only one DSP line, while the tones under "23.2 Stereo Tone DSP" use
two DSP lines.
For information about tones that use DSP, see "22 Tone with DSP List".
11.2.2 DSP Line Assignment
Selecting multiple tones with DSP at the same time creates the possibility that there will not be enough DSP lines. In this
case, the last selected tone with DSP is given priority. Some DSP line(s) already being used will be released so they can
be assigned to the last selected tone.
