hrrm, this is purely theoretical. We can either add it because we MIGHT want it, or wait.

Right, but what it DOES do is take away the overloading of controls. With overloaded controls, a plugin developer has to specify control type (float/double/int), default value (N/A), ranges (a priori), flags for 'NO-PRESET', etc. So many things that don't _REALLY_ apply to these pseudo-controls. I'm just exploring alternatives to it, trying to find something more elegant. The host could walk through a list of known 'special' event ports, such as tempo. These special event ports get special events. They are still events, but they are not really 'control set' events (well, they may taste that way..). What the plugin feeds it for a queue doesn't really matter. These are special to the host/timeline setup and to the plugin. Hrrm, how does that affect controllers and output ports. Hrrm. Another alternative - have a new control type that does not have default, range, etc fields. SYS_CTRL just has hints to the host about the existence of a 'special' event port, without actually specifying a full control. Other ideas/thoughts? I'm off again tomorrow for the Christmas holidays. I'm going to try to be online, but no guarantees as to how effective I'll be from my mother's house :) Work will resume with a passion in the new year.
