Port (or Tracks) can be safely added during playback, however the disk-reader's playback buffer is initially empty. This lead to false-positive Underrun() signals when processing takes place before or concurrently with re-filling the disk-buffer for the new channels. Now new empty buffers are ignored, and produce silence until the initial refill is complete. There is however no per-channel de-click in, yet. This fixes: play some audio track, ctrl+drag a region to the drop-zone, creating a new track while playing.
