Groove causes audio dropout when slowly ramping from off to on

    Hi guys,
    I'm having some problems with groove. Mainly being I'm getting audio dropouts when using a [line~] to ramp the speed up to 1. from 0. or vice a versa over 5000ms. I've checked this with both resampling on and off (not that it should make a difference). I have also tried putting a dcblocking stage after groove incase slowing down that much creates some DC.
    I've included a cycle at 220hz in the patch to illustrate the dropout.
    The patch is here:

      For me, the problem goes away when I get rid of the resample attribute. It's worth noting that the interruption of the audio chain happens whether the groove~ is hooked up to the dac or not.

      Yes, I worked out that If I get rid of resample and use an ADSR to smooth the output of groove I can get rid of the troublesome clicks!
      Is this a bug in the resampling function of groove or am I abusing it?
      I'm just a sucker for those aliasing effects you get when slowing down a resampled groove, shame I can't harness them with this kind of patch.

      I think it's probably a groove~ resampling bug. Maybe a denormal issue? I submitted it to Cycling.
