Previously i asked about getting progress bar with waveform view for buffer~ and groove~. I also wanted a CD player style display of the current time, which i was able to work out with LCD fine. I asked this because needed to know where I was in the current file, in order to make some decisions during live performance depending on what files is playing and how far along we are in that file what amplitudes are on the horizon, etc.
AND because I thought this would be way easier to do with a buffer already present for waveforms to be displayed.
But, in the case that you are playing long, large files it really is preferable to use sfplay. This strikes me as a much harder problem and the idea of having a waveform overview is likely unrealistic (and would perhaps need a buffer anyway, defeating the whole purpose and advantage of using splay.
So, like my buffer/groove patch I have a fancy drag & drop loader for sound files (see and be impressed haha) using the drop file and a jit cellblock (ooh, and yes it scrolls!) and I have my sexy LCD which shows the time elapsed like a CD player. But I fear the progress bar part is where I run out of max knowhow.
