with live programming in mind.  It supports interactive programming in a REPL
style, compiling and binding code just-in-time.  Although Extempore has its
roots in 'live coding' of audiovisual media art, it is suitable for any task
domain where dynamic run-time modifiability and good numerical performance are
required.  Extempore also has strong timing and concurrency semantics, which
are helpful when working in problem spaces where timing is important (such as
audio and video).")

      (description
       "mididings is a MIDI router/processor based on Python, supporting ALSA
and JACK MIDI.  Features include:

@itemize
@item MIDI routing and filtering; filter events depending on their event type,
  channel, note number, velocity, etc., and freely route them between an
  arbitrary number of input and output ports.
@item Modifying and converting MIDI events; transpose notes, apply velocity
  curves, change controller values and ranges, or convert events to any other
  MIDI event type. mididings also includes more complex functions like a
  diatonic harmonizer, floating split points, latched notes, and more.
@item Seamless switching between patches; set up different \"scenes\", each
  with its own MIDI routing and processing, and switch between them at any time,
  even while playing.  Switching scenes does not affect notes already held, and
  does not result in dropouts or stuck notes!
@item MIDI event monitoring, running external commands; print MIDI event data
  to the console to help debugging your patches and configuring your MIDI
  controllers.  In addition to its MIDI output, mididings can also execute shell
  commands and send OSC or DBUS messages.

      (description "Demlo is a music library organizer.  It can encode, fix
case, change folder hierarchy according to tags or file properties, tag from
an online database, copy covers while ignoring duplicates or those below a
quality threshold, and much more.  It makes it possible to manage your
libraries uniformly and dynamically.  You can write your own rules to fit your
needs best.

Demlo can address any of these recurring music library issues (and much more):

@itemize
@item Fix the lack of folder structure.
@item Normalize tags, fix their case, chose which tags to keep and which to
discard.
@item Handle lossy and lossless audio differently.
@item Handle mp3 id3tags hell...
@item Handle multiple covers, whether embedded and/or external, resize covers,
discard bad quality ones.
@end itemize\n")

Orca is not a synthesizer, but a flexible livecoding environment capable of

Renoise, VCV Rack, or SuperCollider.")
