When the speed (the level of control signal) comes to 0, it always creates clicks. I have searched the forum and most solutions for avoiding clicks of groove~ is about the clicks that happen during the looping position change. I found no solutions for removing clicks that happen during the speed change of groove~ playback.
I tried ADSR by using “>~ 0.5″ to trigger the the attack and release time of ADSR envelop but it still creates clicks when the control signal of Groove~ comes to 0.
Could anyone help ?

Thank you so much.

The patcher below adresses the first possible cause by smoothing the speed changes. The second possible cause is solved by silencing groove~ with a short fade when the speed goes below a specific threshold. Another solution would be the insertion of a DC bias filter (highpass filter with a very very low cutoff frequency).

Hope this helps.
