You have to make sure that the max frames for your AUs are set up -
by default the varispeed won't be calling for more than its max
frames setting, but if this is bigger than the AU you are connected
too, (the format converter), then you'll be asking for it to process
more sample frames than you've told it to do.

I am having a bit of trouble with a FormatConverter AU. I have a
VariRate converter set up to pull on the Format converter and all
is well when the VariRate converter playback rate is set <= 1.0.
When playback is even slightly greater than 1.0, I get a -10874
error (too many samples to render) returned from the
FormatConverter. I am guessing that the FormatConverter is
allocating some internal memory in support of an internal FIR or
similar filter and by increasing the playback rate of VariRate, I
am now exceeding the number of frames that the FormatConverter had
previously allocated to handle the render request.
When does (if my assumption is correct) the FormatConverter
allocate it's internal memory? Does it use the first render
request as a size gauge? How can I get it to allocate 5 to 10%
more to allow for changes from my down stream VariRate converter,
or is there some way to tell it how much to allocate before I
initialize the AU?
Thanks,
