Bitcrush

Version 2.3 - 'Bitcrush'

Wednesday 28th January, 2015

Breaking Changes

• Playing chords with the fn chord now divides the amplitiude of each
  resulting synth by the number of notes in the chord. This ensures the
  resulting amplitude isn't excessive and is normalised.
• Chords now evaluate their args once and those args are used for all
  synth triggers. This means random values are only generated once and
  are similar across all notes in the chord. Previous behaviour can be
  obtained by calling play multiple times with no interleaved sleeps.
• Ensure each new thread's random number generator is unique yet seeded
  in a deterministic manner. This stops random vals across at from
  being identical.
• range is now exclusive: (range 1, 5) #=> (ring 1, 2, 3, 4)

New

• New fn density for compressing and repeating time Dr Who style. For
  example, wrapping some code with a call to density of 2 will double
  the bpm for that block as well as repeating it twice. This ensures the
  block takes the same amount of time to execute while doing double the
  work.
• New fns with_bpm_mul and use_bpm_mul which will multiply the
  current bpm by a specified amount. Useful for slowing down and
  speeding up the execution of a specific thread or live_loop.
• New fn rdist - generate a random number with a centred distribution
• New examples: square skit, shufflit and tilburg

Improvements

• Teach control to ignore nil nodes i.e. control nil, amp: 3 will do
  nothing.
• Teach Float#times to yield a float to the block. For example,
  3.4.times {|v| puts v} will yield 0.0, 1.0 and 2.0.
• Synth, Sample and FX args now handle bools and nil correctly. true
  resolves to 1.0 and false, nil resolve to 0.0. This allows you
  to write code such as: play :e3, invert_wave: true
• Teach at to handle varying block arities differently. See docs for
  more detail. Original behaviour is preserved and only extended.
• App now checks for updates (at most once every 2 weeks). This may be
  disabled in the prefs.
• Teach :reverb FX to extend its kill delay time with larger room
  sizes to reduce the chance of clipping.

Synths & FX

• New FX bitcrusher - for crunching and destroying those hi-fi sounds.
• New FX flanger - a classic swhooshing effect typically used with
  vocals and guitars.
• New FX ring - ring modulation for that friendly Dalek sound
• New FX bpf - a band pass filter
• New FX rbpf - a resonant band pass filter
• New FX nbpf - a normalised band pass filter
• New FX nrbpf - a normalised resonant band pass filter

New Samples

• perc_snap - a finger snap
• perc_snap2 - another finger snap
• bd_ada - a bass drum
• guit_em9 - a lovely guitar arpegio over Em9

Bug Fixes

• Namespace live_loop fn and thread names to stop them clashing with
  standard user defined threads and fns.
• GUI no longer crashes when you start a line with a symbol.
• with_fx now returns the result of the block
• Kill zombie scsynth servers on startup for better crash recovery.
• Handle paths with UTF8 characters gracefully
• Force sample rate for output and input to 44k on OS X. This stops
  scsynth from crashing when output and input sample rates are
  different.
