1.3.3 (2019-08-16)

  • New alda.lisp function, midi-note, is available as an alternative to
    pitch that is occasionally useful for algorithmic compositions, etc. For
    example, instead of (note (pitch :c :sharp)), you can specify the MIDI note
    number, (note (midi-note 61)).

1.3.1 (2019-05-05)

  • Tabs can now be used as whitespace in an Alda score.

  • Fixed a bug where attempting to play an empty score (e.g. c d e, which
    results in an empty score because there are no instruments) results in a

    The problem was that there were no instruments, so the MIDI system wasn't
    being set up. However, we expect the MIDI system to be set up even if there
    are no instruments and no notes to play, because we use the MIDI Sequencer to
    schedule notes.

1.3.0 (2019-04-14)

  • New CLI command: alda export and REPL command: :export

    This command exports an Alda score to another format. Currently, the only
    supported format is MIDI. MIDI files are exported at a resolution of 128
    pulses per quarter note (PPQ).

    The score is provided in the same way as it is for alda play and alda parse: by specifying either a -f / --file, a string of -c / --code, or
    piping in the code via STDIN.

    alda export -f my-score.alda -o my-score.alda
    alda export -c 'piano: c8 d e f' -o piano-notes.mid
    echo 'piano: c8 d e f' | alda export -o piano-notes.mid

    The :export REPL command takes a single argument, the output filename:

    > :export /path/to/desired-filename.mid
  • The alda parse JSON output has a couple of new keys: tempo/values and
    tempo/role. These values are used internally to schedule MIDI notes in a
    way that is exportable.

1.2.0 (2019-01-19)

  • New CLI command: alda instruments and REPL command: :instruments

    This new command lists all available instruments, which is currently the 128
    instruments in the General MIDI spec, as well as midi-percussion.

    NB: Alda does have a number of aliases for these instruments, e.g. piano is
    recognized as midi-acoustic-grand-piano. These aliases are not included in
    the list.

  • Made adjustments to the command that prints for Windows users when running
    alda update to update the Alda client.

    For details, see issue #35.

1.1.0 (2018-12-01)

New feature alert!

An "alternate
feature has been added to the Alda language. The syntax looks like this:

  [ c8 d e f
    [g f e4]'1-3
    [g a b > c4.]'4

This allows you to have repeated phrases that can differ on each iteration. In
the example above, each repeat starts with c8 d e f; on times 1 through 3
through the repeated phrase, the phrase ends with g f e4, whereas on the 4th
time through, the phrase ends with g a b > c4..

Note that these "adjustments" can occur anywhere within the repeated phrase, not
necessarily at the end, making this feature of Alda more flexible than the
"alternate endings" notation seen in sheet music. To illustrate this, here is
another example where the phrase has what you might describe as an "alternate
beginning" and an "alternate middle":

  [ [c8 d e]'1,3 [e8 d c]'1,3
    [g f e]'1-3 [g a b]'4
    > c <

Thanks to @elyisgreat for the initial idea/discussion and @pzxwang for
implementing the feature! 🎈

1.0.1 (2018-11-24)

Whoops! It turns out that the mechanism we had in place in the Alda client for
determining whether or not your version of Alda is up-to-date had a flaw that
prevents one from updating from Alda 1.0.0-rcXX to Alda 1.0.0!

That's fixed in this version. Also, your client will be able to update to the
latest version now because now the latest version is 1.0.1 instead of 1.0.0. :)

1.0.0 (2018-11-24)

This release is functionally equivalent to the previous release, 1.0.0-rc85.
After 3 years of working on a series of 1.0.0 release candidates, the focus has
shifted toward re-architecting Alda in a way that will allow us to make some
substantial improvements. The result of this restructuring will become a new
major version of Alda, version 2.0.0.

The work has only just started on Alda 2.0.0, and it will probably be a long
while before the initial release in the 2.0.0 series. We will continue to
maintain the 1.0.0 series in the meantime. As such, it feels like now is as good
a time as any to release Alda 1.0.0!

1.0.0-rc85 (2018-10-28)

  • Made internal improvements to the Alda sound engine. Specifically, the sound
    engine now uses a Java MIDI Sequencer to schedule and play MIDI notes, whereas
    before we were using a third party library called JSyn.

    You shouldn't notice any difference in note scheduling, but if you do notice
    any problems, please file an issue in the
    alda-sound-engine-clj repo so that we can address them!

  • The schedule function has been removed from alda.lisp. Scheduled functions
    haven't been very useful since we moved to a client/server architecture, and
    we haven't implemented a way for them to work with the new changes to the
    sound engine. So, we are removing the feature for now. We may re-implement the
    scheduled functions feature in the future, in a way that works with both the
    client/server architecture and the current implementation of the sound engine.

    For more context on this, see alda-core#65.
