I am using waveform to randomly jump around the start and end points of a sample but there are glitches. Is there any way of making sure that the start and end points are always at the start of a cycle?

that would require some sample accurate random jumping...

if you are using groove~ as your playback object, you could use that 

right outlet to drive a little wave~ object refering to a windowing 

envelope stored in another buffer~. this envelope would have a very 

fast fade-in at the beginning and a very fast fade-out at the end...

no clicking, no popping... well ...unless you randomly jump halfway

through the windowing envelope...

Not exactly, but: Check out the grid+snap subpatcher of the 

[waveform~] help file. You can find zero crossings with this feature, 

which might give you what you want. - David

The start of a cycle in waveform
