With the host apps we've concentrated on the hosting of the 1-1 effects

Please don't forget the less common case. Who knows what innovative effects
someone will come up with without the 1-1 restriction.

Sure... but this is primarily a job for the host app - my point was that we have the work done from our end I believe...

we could define another audio unit type if we wanted to distinguish between
more run of the mill format conversions and musical effect type conversions
(like time-stretching)

This seems like merely a semantic difference. So is presenting yourself as
an AudioUnit Effect an implicit guarantee that you are a 1-1 plug-in?

I don't want to change this assumption of the aufx type of plugins - it is a known quantity and covers most of the existing effects (with the only allowance being made for plugins that have potential differences between numChannels). It seems to me a reasonable guarantee/contract to provide...

I think it isn't just a syntactic difference but a semantic one:)

For instance we publish the AUConverter as an aufc audio unit - but the function of this unit is primarily of a utilitarian nature. If we shared this component Type with those types of units that do something interesting to your audio (like time stretching for instance), then there isn't a way for the host apps to filter out the utility functionality from that a user would I think prefer to see in this space.
