Algorithm 3 of YM2515 chip (not use chip, only follow its algorithm in C program)
• no feedback
• linear change ampl (4 Hz or 0,25 s)
• ampl_m1 = 408 --> ∆275
• ampl_m2 = 192 --> ∆24
• ampl_c1 = 192 --> ∆96
• ampl_c2 = 40 --> ∆24
• freq_m1 = 1763520*6.0
• freq_m2 = 58784*6.0
• freq_c1 = 117568*6.0
• freq_c2 = 58784*6.0
