AUVarispeed glitches

Hi, 

I'm trying to use the Core Audio supplied AudioUnit Varispeed to speed up my recording 2x in real time. (so that I can switch the effect on and off)

My AUgraph goes like this :

input -> converter -> varispeed -> converter -> mixer (bus1) -> remoteIO

My experience is this : 
- at 1/2 speed  (twice as slow) there is no playback problem, it works
- at 2x speed, sometimes it works, but sometimes the 2x speed audio is glitchy sounding. 

I haven't nailed down why sometimes it works and sometimes it doesn't for 2x speed. shouldn't it just work or not at all? 

Anyone else has experience with this audioUnit? 

Thanks.
