Does anyone know where I'm going wrong here? I'm writing the function envelope into a buffer, so I can use the curve functionality and have breakpoint envelopes that will loop at audio rate. The problem is that I'm getting a click on every cycle. I'm pretty sure the issue is with the way the wave~ object interpolates at the loop point. If I turn the interpolation off then the click disappears. The problem is that I need the interpolation so I can adjust the playback speed without getting artefacts, but I don't want it to interpolate at the loop points as that's screwing up the cycles. Is there a way of doing this with wave~ or should I be using another object? I tried play~ but had the same issue. Not sure what else to do as the these are the only 2 wavetables I know of that are phasor driven and interpolate.

Actually, I've just been looking at it again and it's not quite as simple as just the end loop interpolation. If I use multiple breakpoints, even if I'm jumping to different places within the file that have the same sample value, I still get clicks. In the example below, I'm jumping between different points in the waveform but it's only ever jumping from one 0 crossing to another, but I still get this unwanted sound for each move.

I just realised I left a couple of objects in the previous patch that I was just using for testing, so here it is again without them. Any advise greatly appreciated. I can't work out where these clicks are coming from...

I've added an example into the patch to show that the clicks don't occur when using curve~. Only when playing the curve back through the buffer and wave~ objects.
