   Hi,   
      
   The myster of life isn’t a problem to   
   solve, but a reality to experience   
   - Herbert Frank, Dune   
      
   While toying arround with our new arrow functions.   
   We found that our Dogelog Player DCG implementation   
   does only provide (-->)/2 and not yet phrase/3.   
   Luckily the step from (-->)/2 to phrase/3 is   
   relatively small, and the upcoming release will   
   feature this predicate. It turns out it can be   
   used for Strudel style music coding.   
      
   After going through some rather dry scholarly   
   topics such as set versus tuple oriented processing,   
   we were suddently immersed in Strudel style music   
   coding by passing around oscillator events inside   
   a Dogelog Player notebook. Although we could not   
   demonstrate the same live feedback as Strudel does,   
   one can perceive the magic of composing pipelines   
   by earshot proximity.   
      
   Bye
