I'm sure electrical engineering folks and sound design geeks would love to have a "Trigger" function on the WaveCandy scope. The trigger allows to automatically sync the refresh rate of the scope to the signal in order to "freeze" the waveform. It allows to view how the waveform of a single cycle looks like, independently of the frequency, and without requiring any clicks on the "Freeze" button. I guess that this functionality is simple to implement as ones only need to monitor when the signal voltage (read "floating point sample value") surpasses the user specified threshold and redraw accordingly.
