For sub-block envelope accuracy, you may be able to use the "Time Tagged Triggers" (T3) objects in IEMLIB by Thomas Musil. Or you will have to write an external. I can't think of another way... anyone else have ideas there?
By the way, I have a survey of quite a few granular objects and patches for Pd on my puredata.info page here: http://www.puredata.info/Members/nmariette
I also updated my nm-grainer patch to incorporate OSC input facilities, changed to horizontal sliders, made the controls a bit more obvious, and removed graph on parent functionality to improve speed. That patch is online at my puredata.info page - look for the April 2005 version.

thanks for the tip. It's working much better now. :)
to get a granular effect, change the delay time just before you trigger the amplitude envelope; you can omit the amplitude enveloppe but it's good for fragmenting sounds (some people also add a synchronized filter and/or a pitch shift) most of the time, the enveloppe lasts between 10 and 100 ms; you can use constant or variable enveloppe times (you can also add a random density parameter for the "trigger enveloppe" event)
use some feedback too if you want to get more complex fragmented things
to remove the doppler effect, there are two basic methods: 1. use a sample and hold, like in the sampler.transpose.pd example by Miller Puckette (this method is rather suited to constant enveloppe time / synchronous granular synthesis; the whole granulator is scheduled by a single |phasor~|)
OK, so using a samphold~, phasor~, and vd~, I've got the envelope-less granulator going, but how do I trigger the envelope with sub-block accuracy? I can use vline~ create the envelope itself, but getting it started is the problem.
