+1. The MIDI file implementation should not overload the use of the
+   'dtick' field in cmMidiTrackMsg_t to contain multiple possible
+   meanings of time (e.g. tick,microsecond,seconds,samples etc) or at
+   the very least the current meaning of the field should be held as a
+   flag in the MIDI file.  As it i s the field is ambiguous and it can
+   be difficult to tell what the meaning of the field is in any given
+   algorithm that processes it.
+
+2. Sostenuto pedal should be added to the score and then implemented
+   in cmMidiFileCalcDurations().  When the sostenuto pedal is down
+   only notes that are playing when the pedal is depressed are
+   sustained.
+
+3 As current written the UI control architecture supports only one
+  user interface element (kcApp.h::ctl_t) per DSP instance. This
+  limitation is manifest in kcApp.h::find_ctl() which has no way
+  to distiguish which of multiple ctl_t's to return from a given
+  instId. In fact this problem probably goes deeper into the 
+  way that Fl_Widgets and DSP instances are assocated.
+
+4. TODO:
+  a) When pedal events are inserted via cmGrTksrFltk the inserted event
+  is shifted backward in time.
+
+  b) Test the save/restore function of TakeSeqBldr render takes.
+  c) TakeSeqBldr load should be threaded.
+  d) Eliminate direct communication between cmGrTksb/rFltk and cmTakeSeqBldr.
+  All communcation should be serialized.
+  e) Run with valgrind to see if cmGrGksb/rFltk has any obvious bugs.
+  f) bar select / take select logic is difficult.
+  g) There is often a NAN shown in the position select display UI.
+  h) Add bars to the cmGrTksrFltk view.
