Wavetable Crossfade clicking issue

Hi

I’ve been using the IRCAM Jimmie external called harmv2~ and I’ve noticed it has a click that is linked to the window size. I deconstructed the external and built it back again to find the cause. Having identified the problem, I’m now not sure how to proceed – having tried a few methods and failed.

I’ve attached a test patch for those keen to assist…

Basically, the right hand plays the sound 1/2 cycle out from the left hand playback. The issue appears to occur because the method used in the jimmie abstract requires the cycle~ ramp to jump from 1 to 0 causing the cycle~ wind (amplitude controller) to ramp over its duration very fast causing a momentary click. Add that to the feedback loop and the annoying click persists!

Hope someone can help out here…
