Why don't they trample each other's feet?Well, ATTACK stays in the attic, DECAY in the cellar. (Meaning, multiply the ATTACKnumber by 16, then add on the DECAY number.)Likewise,SUSTAIN and RELEASE share another register.Add16 INPUT "ATTACK-DECAY ";A,D17 INPUT "SUSTAIN ";S18 INPUT "RELEASE ";R20 POKE C+5.1B*A+D:POKE C+6.1B*S+R80 FOR T=1 TO D*.5:NEXTT:REM ATTACK.DECAY.SUSTAIN TIME92 FORT=1 TO D*.3:NEXTT:REM RELEASE TIMESave, then run.Now you can play the same tune sound with different instruments.Try these combinations: AD S R2200990099151223700150Try other combinations.
