Change Log

0.4.1 - 2022-01-09

Fixed

• an embarrassing bug in nanosleep which nullified all attempts at adapting to the measured nanosleep/parknanos precision (the fact that I did not detect this bug makes me wonder if the whole idea is a premature and unnecessary optimization)

0.4.0 - 2022-01-05

Changed

• the task of waiting until the next tick has been abstracted into a Ticker protocol with two implementations: SleepingTicker uses various sleep methods, AudioSyncingTicker synchronizes the ticks to audio-in - unfortunately the latter takes too much CPU in its current form so SleepingTicker remains the default

Fixed

• 100% CPU usage due to the precision of nanosleep/parknanos becoming too large

0.3.0 - 2021-12-24

Added

• a section to the README which describes the pattern lifecycle
• some tests

Changed

• :var forms now check if the resolved var is a function, and if it is, apply it to the arguments following the var inside the :var form

0.2.0 - 2021-12-22

Added

• sequencer/compile: a shorthand for sequencer/compile-pattern-form
• sequencer/register-target accepts an optional target alias (a namespace-qualified keyword) which can be used to refer to the target in :bind maps
• patterns got a delay value: when a pattern is merged onto the timeline, each event of the pattern is delayed by this number of ticks (used to make :play more precise)
• [:delay N]: this new pattern expression sets the delay value of the pattern to N

Changed

• :call pattern expressions can now include function arguments
• :var pattern expressions now wrap the var value in a :bind form with the input bindings if it needs to be compiled (this ensures that they are compiled in the right context and target)

Fixed

• sequencer crashes now properly reset sequencer state

0.1.0 - 2021-12-19

Initial release.
