Is time represented as samples or "ticks" or both/neither? How are discontinuities in the timeline expressed? My stake in the ground is that we need a way to represent time either in musical units or absolute units. The units should be chosen in such a way to avoid rounding errors when converting from one to the other, and should also support at least 24 hours of time range. By way of example, SONAR uses a representation where a 64-bit structure can represent either a floating point absolute time, or an integer musical time in units of 960*(2^16) PPQN. (The choice of PPQN makes conversions to a user editable 960 PPQN efficient.) Conversions are done via a host supplied time converter interface. ---------------------------------------------------------------------- Generalized Music Plugin Interface (GMPI) public discussion list Participation in this list is contingent upon your abiding by the following rules: Please stay on topic.
