PROBLEM TO BE SOLVED: To freely set the constitution of parameters for expressing changes of playing expressions which are conventionally fixed in common as to all tones by allowing a constucted function to instruct the generating of either tone in among instructed tones of one or more according to prescribed conditions in accordance with playing information. SOLUTION: A MIDI message is received (S1302). When a MIDI Key No is smaller than 60 (S1304) and a MIDI Key Velocity is smaller than 100 (S1306), a Tone #1 is sounded (S1308). When the MIDI Key Velocity is equal to or larger than 100 (S1306), a Tone #2 is sounded (S1310). When the MIDI Key No is 100 (S1304) and when a random number is newly generated and the result of the generating of the random number is false (S1312), a Tone #3 is sounded (S1314). When the result of the generating of the random number is true (S1312), a Tone #4 is sounded (S1316). |
