hi frank, thanks for the reply.  <br><br>your system uses extra inlets and outlets on each abstraction to load the preset data, which is something i wanted to avoid if at all possible.  but saying that, i think your system has one really great advantage which i didn&#39;t imagine by myself... the preset data is also passed THRU each abstraction, so abs can be chained together and pass the preset information along that chain.  if all else fails and i can&#39;t come up with anything, then i&#39;ll use that approach too.<br>
<br>that rjlib is looking really excellent now, by the way.  been a couple of months since i checked it out, and it&#39;s really grown.  <br><br>cheers.  matt<br><br><br><br><br>
