zero-crossover sampling

March 10, 2007 | 11:55 pm

Hi, I have a patch changing playing back of a sample based on sample index. When I change the playback possition there are clicks as the switch over doesn’t occour on a zero-crossing. Is there another index~ like object that finds the nearest zero-crossing point at which to change playback possition. Any help would be greatly appreciated.

Thanks

The waveform display object has a zero-crossing mode. Second to last
item on the object palette. Once you drop it in your patch, command
+I brings up the settings and snap to zero-crossing mode is one of
them. Hope that helps.
