Observing time in SMPTE


    Jan 05 2012 | 1:52 am
    Hi! I feel stupid but it's late :-) I'm want something like a "Big Counter" as we can found in many DAW, in Live. I want to monitor the time in SMPTE. With MFL, we can observe the current_song_time in Bar/Beat/Tick but not in time (I now there's something like a "get_current_smpte"... but it's a "get"... and my mouse clicking is not fast enough to update it at a inhuman frame rate :-). So, I divide the "bar beat tick" by 200. But, as I reach a minute, off course I'm having 0.6 instead of 1. So what's the good math behind this? Actually I need the math to calculate it to common SMPTE frames, at least 24, 25 and 30 ifps. Thanks. Jul

      I would simply poll the function 'get_current_smpte...' with metro. (note that observers do basically the same internally)

      Thanks dear Broc. Have you noticed that Live timing is quite strange? The first image is not 40ms long as it should be in 25/ifps, but 20ms. Moreover the smpte is not exactly time aligned to the ifps time indocators. (I hope you understand my english).

      Yes, the timing of Live API seems a bit "sloppy" by design (with variations up to 50ms).
      For perfect sync with Live you need using [transport] or [plugsync]. Here is a patch that calculates SMPTE from the beats (and tempo) output of plugsync.

      Thanks again Broc, you rock!
