Command modifiers. One or more of these is followed by a normal command
NOTE: Parsing code seems to check for '_if' first, then one of ('_t', '_tr', or '_tv'), then one of ('_r' or '_v').
  A0h _r random (replaces an argmuent with two, for range)
  A1h _v variable (replaces an argument with variable number)
  A2h _if (only executes if result of last compare command was true)
  A3h _t time (smoothly changes value over time)

volume/volume2 are treated like ((x / 127)^2), then multiplied together. Default value for both is 127(100%).

variables, default value = -1
00-15 = VAR_xx  local variables
16-31 = GVAR_xx global variables
32-47 = TVAR_xx track variables
