Another approach, more "in the box" in that a digital module with sophisticated options is doing most of the work, but it's a popular module with many other uses. Synchronize Pam's New Workout to the beat, then set up a channel using the RSkip parameter to control the probability of output. Choose whatever waveform works for your accenting mechanism. You could want a boost in volume as the accent, but you could also send parameters to the source of the sound to alter it.
