Is there any way to reverse the playback of a sample using sfplay~? Im currently using a waveform object to set the start and end points of the sample playback and sending these to sprintf before going to sfplay~. Surely if you swap the start and end point values from waveform before they arrive at sfplay~ the sample would play backwards? However, it doesnt seem to work like that. Any help?

It's possible as long as you preload the file and you set the 

bidirectional flag to 1. Although, as you display the sound in the 

[waveform~] object, that means that your sound is loaded in a 

[buffer~], so why don't you use object like [groove~]/[wave~] instead?
