>>> That is what I meant by the control rate needing to be a multiple of 4. In other words, parameters can only be update every 4 samples. As long as this is true, you can run it quickly. <<< Doh!<g> I get it now... It probably seems like hair-splitting, but I'm pretty sure now that we've established with our customers that we render gain at a control rate of 1 sample, they might not accept any less going forward. So for us anyway, and for any other host or plugin that renders sample by sample, the loss of interleave would pose a potential problem. ---------------------------------------------------------------------- Generalized Music Plugin Interface (GMPI) public discussion list Participation in this list is contingent upon your abiding by the following rules: Please stay on topic.
