Strudel Coding in Dogelog Player (Was: Interpreting Arrows in Dogelog Player)

Show all headers | View raw

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
