 # Update: there's an issue open in RubyMotion for this, so hopefully it will get resolved soon.
 #
 # http://hipbyte.myjetbrains.com/youtrack/issue/RM-725
 #
 # In the meantime, here's a workaround: https://gist.github.com/darinwilson/26c8b573a65d8bc4c64b
 
 # if you create a Ruby Hash...
 ruby_hash = { foo: "bar" }
 # ...you can call Ruby methods...
 ruby_hash.has_key?(:foo)

# Utility class that converts a java.util.HashMap instance to a Ruby Hash. RubyMotion will
# start supporting this out of the box at some point, but until then, this can be used
# as a workaround: http://hipbyte.myjetbrains.com/youtrack/issue/RM-725
#
# Usage:
#   HashMapToHash.convert(hashmap)
#
# This supports nested hashes and should assure that all Java-based values are properly converted
# to their Ruby counterparts (i.e. java.lang.String => String).

# Ambient experiment for Sonic Pi (http://sonic-pi.net/)
#
# The piece consists of three long loops, each of which plays one of
# two randomly selected pitches. Each note has different attack,
# release and sleep values, so that they move in and out of phase
# with each other. This can play for quite awhile without
# repeating itself :)

# Phasing Piano for Sonic Pi, coded by Darin Wilson
# inspired by Steve Reich's Clapping Music
#
# This piece consists of two threads, each playing the same short melodic phrase.
#
# On every third pass through the phrase, one of the threads shifts the phase by
# 1/4 of a beat, moving it more and more out of phase. Eventually, it comes
# back around to where it started, and the piece ends.
