       This manual page explains the rumor program. It is a  realtime  monophonic  (with  chords)
       MIDI  keyboard to Lilypond converter. It receives MIDI events, quantizes them according to
       its metronome on the fly and outputs  handwritten-like  corresponding  Lilypond  notation.
       Tempo, meter, key and other parameters can be set via command-line options


       Default start-up values are --alsa=64:0,65:0 --tempo=100 --meter=44 --grain=16 --key=c.

              Set minimum time resolution to the NUMth note. Only powers of two are valid, from 1
              up to 128.

              Ignore any rests between notes. Every note terminates upon the start  of  the  next

              Do not use dotted notes (dotted rests are always disallowed).

              Set  time  signature.  Bar will have P beats of duration of the Qth note. Metronome
              will sound every beat. (thus e.g. 4/4 and 8/8  will  give  the  same  output,  only
              metronome behavior will change).

              Q must be a power of two. Slash may be omited if P and Q are both smaller than 10.

              Metronome  speed  will be BPM beats per minute. Note that what is considered a beat
              is determined by --meter.

              Start metronome upon arrival of the first  MIDI  note,  at  the  beginning  of  bar
              (BEAT=1) unless overridden.

       --flat Output only pitches as you play, no lengths. Metronome will not be started.

              Disables chords (groups of notes pressed and released "simultaneously", with regard
              to quantization). Enabled by default.

              Output duration indication after every  note,  even  if  it  remains  the  same  as

              Do  not  use  Lilypond  relative  notation.  Instead, all pitches have their octave
              indicated by (possibly zero) tics or commas.

              LANG can be one of ne (default: ces, c, cis, ...), en, en-short, de,  no,  sv,  it,
              ca,  es.  Languages  match  those used by Lilypond (not necessarily the version you
              have installed, though). Note that pitch names can be always overridden  by  rumor-
              pitches (see section 5. Scripting).

              Set  base  note  of current scale, used to resolve enharmonic ambiguities (i.e. fis
              vs. ges). Valid value for KEY is any pitch having less  than  two  accidentals,  in
              current language (--lang; this option must precede --key in order to have effect).

              Run  --sample-sheet  Produce  complete  Lilypond  file  showing all possible rhythm
              notations and chromatic scale in all possible keys (see --key). It is influenced by
              --meter, --grain and also user-defined notations (see --script).

              Strip  leading  and  trailing  rests  from  output. First and last bars may thus be

              Output can be fed directly into Lilypond. It will be one--line staff in violin clef
              and key signature as determined by --accidentals.

              Set  number  of  sharps or flats (if NUM is positive or negative, respectively) for
              full Lilypond output. No effect without --full.

              Run guile script FILE before beginning. See section 5. Scripting.

              Use ALSA interface. If argument is specified, connect input to client IC on port IP
              and  output  to  OC:OP.  By default, Rumor will try to use 64:0,65:0. If connection
              fails, you can use aconnect to do this manually.

              If you specify only one pair C:P, it will be the output port. This is  useful  with

              Use  OSS  interface.  Device  number  0  on  /dev/sequencer  will  be  used, unless
              overridden by DEV.

       --kbd  Emulate MIDI keyboard using ordinary keyboard. An ordinary MIDI interface (ALSA  or
              OSS)  is still needed for metronome and echoing. Standard input must be a terminal.
              There is a usable keyboard layout builtin; however, key bindings  are  configurable
              via (rumor-kbd ...) (see section 5. Scripting).

              Be  verbose.  This  option  may  be  used  more  times and every time will increase
              verbosity level by 1. If it is greater than 3 and Rumor was compiled with debuggins
              support,  debugging  and  tracing  messages  will  be printed. If verbosity is zero
              (default), Rumor will only report errors.





       Rumor's only purpose is to help out with music transcriptions (even  of  polyphonic  music
       with  separated voices); typical usage is to write Lilypond file skeleton by hand and then
       paste Rumor output into it. It does not want to  be  a  full-blown  quantization  program;
       fancy features like tuplets, polyphony and tempo tracking were ommited deliberately.

       Rumor mimics handwritten Lilypond source:

       (1)  it  uses  relative  notation and omits note length if it has not changed (both can be
       switched off though).

       (2) it writes rhythms intelligently, in relation to bar position (tied single notes,  over
       barlines if necessary)

       (3)  it  resolves  enharmonic  ambiguities  (e.g. gis/as) given the --key=NOTE option (see
       section 4. Invocation)

       (4) It is scriptable, with support for user-defined rhythm notations, keyboard layout  and
       pitch names (dutch and italian being built-in). See section 5. Scripting.

       (5) It supports chords (simlutaneous notes), using the <c e>8 syntax.

       (6) It can talk to MIDI I/O via ALSA or OSS.

       (7)  It  can  emulate  MIDI  keyboard using ordinary (computer) keyboard, key layout being


       Should be rewritten in python. Otherwise no known bugs.


       A minimalistic rumor session follows (play keyboard, then press ^-C).

       -m68 (or equivalently, --meter=6/8) sets six-eights bar, -kb (--key=b)  indicates  b-based
       scale, -g32 (--grain=32) sets resolution to 32nd notes.
