Do you know what thread this was posted in? It might help figure out how the cross fading and overlapping is done which isn't fully clear by looking the patch.
Each play looks to be alternating, they are windowed and presumably the start and end envelopes overlap. I'm just not following the patch 100% : )
thanks for all the tips and suggestions. i have been away for a few days and i have to find some time tonight to try it all out but i suppose there is a good solution in one of all your posts.
thank you very much.
