Some thoughts on a future "Synchronization" feature for Synchron Player's Mix presetting.
There is currently a particular make and type of spatialisation plugins that have a unique and very convenient "Edit Group" feature. This optional feature allows many instances of the plugins to be assigned to one of 8 Edit Groups, such that all members of an Edit Group can be adjusted simultaneously and automatically simply by operating the controls of any one member of that Group, either manually or by automation.
This Group-Editing facility works regardless of whether the plugins are enabled or bypassed, so that when any member of a Group is switched from bypassed to enabled it will immediately start operating with the latest Edit Group settings.
In the case of the algorithmic reverb plugin of this particular make and type, the Edit Group facility works not only for parameter editing but also for selection and loading of any one of many hundreds of reverb presets. However, this is not necessarily the same kind of thing as loading IR files into a convolution type of reverb plugin. Very many optional algorithmic-reverb presets may be loaded into RAM along with the first plugin of the type, without causing a huge extra RAM burden. But loading very many optional IR files into RAM along with the first Synchron Player to be inserted may not be quite as economical with RAM.
Hence I'm not optimistic about the prospect of seeing a new and comprehensive "Synchronisation" feature added to Synchron Player's Mix presetting. But maybe VSL's ever-resourceful and inventive devs will prove me wrong - anyway I hope so.
