DESCRIPTION
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
OPTIONS
Default start-up values are --alsa=64:0,65:0 --tempo=100 --meter=44 --grain=16 --key=c.
-g,--grain=NUM
Set minimum time resolution to the NUMth note. Only powers of two are valid, from 1 up to 128.
-l,--legato
Ignore any rests between notes. Every note terminates upon the start of the next one.
-D,--no-dots
Do not use dotted notes (dotted rests are always disallowed).
-m,--meter=P[/]Q
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.
-t,--tempo=BPM
Metronome speed will be BPM beats per minute. Note that what is considered a beat is determined by
--meter.
-w,--wait=BEAT
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.
--no-chords
Disables chords (groups of notes pressed and released "simultaneously", with regard to
quantization). Enabled by default.
--explicit-durations
Output duration indication after every note, even if it remains the same as preceedingly.
--absolute-pitches
Do not use Lilypond relative notation. Instead, all pitches have their octave indicated by
(possibly zero) tics or commas.
--lang=LANG
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).
-k,--key=KEY
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).
-s,--strip
Strip leading and trailing rests from output. First and last bars may thus be incomplete.
-f,--full
Output can be fed directly into Lilypond. It will be one--line staff in violin clef and key
signature as determined by --accidentals.
-a,--accidentals=NUM
Set number of sharps or flats (if NUM is positive or negative, respectively) for full Lilypond
output. No effect without --full.
--script=FILE
Run guile script FILE before beginning. See section 5. Scripting.
--alsa=[[IC:IP,]OC:OP]
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 --kbd.
--oss[=DEV]
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).
-v,--verbose
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.

NOTES
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 scriptable.
BUGS
Should be rewritten in python. Otherwise no known bugs.
EXAMPLE
A minimalistic rumor session follows (play keyboard, then press ^-C).
vaclav@frigo:~/ujf/quant/rumor$ ./rumor -m68 -kb -g32

-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.
