I'm pleased to announce the availability of [polygrainsynth], a polyphonic granular synthesizer built on the [a_grain] abstraction written by Jamie Bullock. Much like its older sibling [polywavesynth], [polygrainsynth] does automatic allocation and management of n voices, where n is limited only by your available processing power.
See http://www.pkstonemusic.com/polygrainsynth.html for all you need to know, and http://www.pkstonemusic.com/code/polygrainsynth.tgz to download the archive.
I've added some examples of this synthesizer in use to my music page: http://www.pkstonemusic.com/pubmusic.html (particularly in the section "Amber Grains of Wave").
Enjoy; let me know if there are problems (but please read the web page completely before asking!). Also let me know how you like it.

P.S. [polywavesynth] has been updated. See http://www.pkstonemusic.com/pd_code.html for a convenient link to both synthesizers.
