Your description sounds like what I'm experiencing as well. I've tried
both OSS emulation and alsa,"hw:0,0". I've tried -r and -z:nointbuf,
perhaps I should do more thorough testing with those options though.
Hmm. Yeah not sure about the segfaults, whether its related to hardware
or not (haven't got one in a while).

My part in bringing about the vocoder plugin only took about 1 day :)
The real work was done by the original author. I also am quite amazed by
it! I've been having fun vocoding stuff. Its really cool to connect up a
keyboard controlled synthesizer (I've tried sound font patches as well
as an external analog synth), then you can modify the tones and cords
that are used for the carrier. Makes for a nice musical effect with
vocals. Lates..
