Description
Use the snapshot~ object to convert a signal value into a float message when a bang is received or according to a specified interval. The interval can be set to a fixed or tempo-relative rate using the Max time format syntax.
Examples
Discussion
The snapshot~ object is sample-accurate when Scheduler in Audio Interrupt is enabled. More details here.
