[gmpi] Re: R: Re: Topic 4: Host Interface


transport control has nothing to do with controlling the flow
graph.

I must be missing something. I have a very centralized view of the host as the master of timeline, data flow, and external I/O devices. The host is often the source of time ordered content such as sample data, musical events, automation. How can transport control (stop, rewind, play) not be related to controlling the data in the flow graph?

however, i think that any graph node can be the transport master.

In my centralized view, this could only happen if the host provides an interface for a plug to control the transport.

not coming from me, that's for sure. i've made it clear that although
i think out-of-process connectivity is cool, i don't support it as
part of GMPI.

                                                                   If we

transport control has nothing to do with controlling the flow
graph. thats why i responded to ron's message in the way i
did. transport control determines what transport-aware nodes do when
they are executed. it does not control when they are executed or in
what order: that's the job of the host.

however, i think that any graph node can be the transport master.
