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.
