      you cannot. it is not the groove~ object which causes
      clicks, it is the fact that you are looping the sample.
      you could process the sample in the buffer by filtering
      the end and begin in a way to avoid clicks, but that is
      out of the question as soon as you want to have dynamic
      start and end points for the loop.
      i am using waves restoration in OS 9 and powercore
      resoration plug-ins in OS X but you can also make a
      simple declicker right in you max app behind the groove ...

      I think what youre probably after (its free) is the xgroove-external
      from the xsample library.
      cheers.

      or use
      tap.buffer.snap~
      to exactify your loop points.
      (hmm - exactify - nice!)

      did i miss something? why can't loop sync be used to make an envelope for the sample? like trapezoid~?

      I place a 10 ms 40dB ramp in the audio at the start of the record and then hold off the end of recording for 10ms while I do the same to the tail. I also use snapshot to do a similar shaping at playback. However this playback shaping is only applied when varying the start and stop points. Also make sure you AC couple the audio (dcblocker~) right before it hits the record buffer.
      The timing of the above system is slightly (10ms) behind (and long) so I have a pre-delay I can invoke when fixing the initial offset is critical, but I just live with the extra length. I have found this approach to let me sample, loop and modify with impunity.
