Hello,
The idea of sample-based absolute timestamp and periodical syncronization events (for exact adjustments) seems to be quite sane. If plugin doesn't need MIDI clock syncronization, then one just ignores SYNC events.
While audio synchronization is necessary for many common types of plugins (e.g., chorus or modulated reverb).
enum {
OSP_SYNC_EXT = 1862340480 // divides by most of numbers that could be
// used as a part of measure
};struct osp_aux_sync : public _osp_aux
{
// if flag is set, then there is data for
enum {MBT=1, EXT=2, A=4, B=8, KEY=16};
int flags; int m, // measures
b, // beats
t; // 1/960 of beat ext; // offset within beat
// (in EXT units (1/OSP_SYNC_EXT)) int mA,mB; // for A/B meter (for example, waltz is 3/4)
// A also means beats in measure int key; // base tune key,
// &0x1000 for minor, &0xFF%12 - for relative key
};
Thanks, George.
