yes, it's possible to make a switch for turning the patchselector to internal/external program-changes (added this to the to-do-list). It will have a better performance but the Gui will not respond to the changes of the SID then. I also planned to implement a plugin-internal multimode - so you can play different SID's with different parameters by one SIDControl, only. SIDControl is win32 compatible, only and an AU-version is not planned by my side.
