NAME¶

SYNOPSIS¶

DESCRIPTION¶

If you want to check an abc tune, it is recommended that you use abc2midi with the -c option. This performs extra checks that abc2abc does not do.

The output of abc2abc goes to standard output. Use redirection to save it to a file.

OPTIONS¶

-s

Rework spacing in the file (which affects how notes are beamed together when the music is printed out). This option does not appear to be working correctly.

-n X

Reformats the abc file with line breaks every X bars.

-b

Don't do bar checking.

-r

Don't do repeat checking.

-e

Don't report errors.

-t n

Transpose tune by n semitones. This function will also work with K: none or one of -nokeys or -nokeyf. If a voice is assigned to channel 10 (drum channel) using a %%MIDI channel 10 command, then this voice is never transposed.

-nda

Convert double accidentals in guitar chord to another chord though strictly not correct.

-u

Update notation; the older notation + + for chords is replaced by [] and s s for slurs is replaced by ().

-OCC

Accept the old notation for chord. Normally this is turned off, since it conflicts with abc draft standard version 2.0 for decorations (eg. +crescendo(+).

-d

Re-notate the tune with all note lengths doubled. The unit length specified by the L: field command is halved (e.g. L:1/8 to L:1/16).

-v

Re-notate the tune with all note lengths halved. The unit length specified by the L: field command is doubled (e.g. L:1/8 to L:1/4).

-ver

Prints version number and exits.

-V X[,Y...]

For multivoiced abc files (i.e. contains V: field commands), only voices X[,Y,...] are copied.

-P X,[,Y...]

For multivoiced abc files (i.e. contains V: field commands), all voices except X[,Y...] remain the same. Voices X,Y... are modified according the other runtime parameters.

-X n

For a file containing many tunes, the X: reference numbers are renumbered sequentially starting from number n.

-xref n

Only the tune with X: n is processed.

-nokeys

No key signature will be assumed. Instead, sharps and naturals will be placed wherever they are needed.

-nokeyf

No key signature will be assumed. Instead, flats and naturals will be placed wherever they are needed.

-usekey sf

This will force abc2abc to output the notes in the key signature keys[sf] where sf specifies the number of flats (-negative) or sharps (+positive) in the key signature. It is a number between -5 and +5 inclusive.

* Normally abc2abc will convert the deprecated notation for decorations (eg. !ppp!) to the abc version 2.0 draft standard (eg. +ppp+). If you do not wish to change to this standard include the -OCC flag.
