NoteSeq

A command line tool for playing note sequences.

Usage

Playing a note sequence is as easy as:

noteseq C E G

Accidentals

Accidentals # an b can be added to any note.

noteseq C Eb G#

They can also be stacked and mixed.

noteseq Cbb E#### Gb#

Octaves

To specify the octave of each note, add the octave number at the end of each note name.

noteseq E#5 D5 B4 G4 Bb4

Tip

You don't need to specify the octave when playing in the 4th octave, since this is the default octave. Therefore the same sequence could be written as:

noteseq E#5 D5 B G Bb

Note values

To control the note values another number is appended at the very end of the note name, separated by a :. This number represents the divisor in the fraction that is the note length. E.g. 8 means an 1/8 note.

noteseq D:8 E:8 F:8 G:8 E:4 C:8 D:4

Tempo

Change the tempo (in BPMs) by using the option -t or --tempo. The default tempo is 120 BPM.

noteseq --tempo 180 D:8 E:8 F:8 G:8 E:4 C:8 D:4

Fermata

A fermata can be applied to the last note in the sequence with -f or --fermata.

noteseq --fermata F4:8 A4:8 C5:8 F5:1

Tuning

The tuning can be specified with --tuning. The default tuning is 440 Hz.

noteseq --tuning 432 F4:8 A4:8 C5:8 F5:1

Technical configuration

Noteseq will use your default output device for playing back sound. This can be overridden by providing the option -d or --device, specifying the device name.

noteseq --device "My audio device" C D E

Sample rate can be changed with -s or --sample-rate. Default sample rate is 48000.

noteseq --sample-rate 44100 C D E
