| sync | enum | off | Sets the sync mode of the rate object. The sync mode determines whether or not the rate object will stay in phase with the input signal, and the method used for synchronization. When the output of the rate object is 'in phase,' the input and output signals align precisely at the least common multiple of their periods (i.e., they pass through zero and begin a new cycle at precisely the same time). If the signals are in phase, and a new multiplier value is received, the rate object changes the frequency of its output ramp accordingly. However, the change in multiplier values means that the two signals may be out of phase. The rate object handles this situation in one of three different ways, depending on the sync mode.
Possible values:
0 = 'off' ( Disable the sync mode )
The arguments @sync 0 or @sync off disables the sync mode of the rate object (the default mode). In this mode rate never responds to phase differences; when a new multiplier is received, the rate object adjusts the speed of its output ramps and they continue without interruption. Since this mode never introduces a discontinuous jump in the ramp signal, it may be useful if phase is unimportant.
1 = 'lock' ( Set the lock mode for sync )
The arguments @sync 1 or @sync lock set the lock mode of the rate object. In sync lock mode, the rate object performs synchronization whenever a new multiplier is received. The rate object immediately calculates the proper ramp position which corresponds to being 'in phase' with the new multiplier value, and jumps to that position.
2 = 'cycle' ( Set the cycle mode for sync )
The arguments @sync 2 or @sync cycle set the cycle mode of the rate object. In cycle mode, the rate object does not change the phase of its output until the end of the current cycle. When the input ramp reaches its peak and starts over from zero, the rate object immediately restarts the output ramp, causing a discontinuity in the output signal, and immediate phase synchronization.
