New major features
Support for other synth types Added a universal silence function (necessary for "pluck" type) Did away with the unnecessary soxpipes variable Support two-note harmonies (see pokemon-gsc-mainmenu for example) Support flat notes Auto-reset the notes array after calling createSoxPipes To distinguish between nonlooped and looped melodies, you now have to call an empty echo. Better solution than putting a newline at the start of the output. See sleeping-terror.sh for example.

A library for GNU bash making it easier to create music with the power of SoX
|
||||
synths.
|
||||
|
||||
If you're one of these people:
|
||||
|
||||
- a Bash programmer
|
||||
- suck at reading sheet music
|
||||
- finds MML too difficult
|
||||
- too lazy to learn FamiTracker
|
||||
- think that scientific note duration is the best thing since sliced bread
|
||||
|
||||
Then try this crappy library of mine!
|
||||
|
||||
Some features of this library:
|
||||
|
||||
- Easy to write syntax for inputting notes ("$duration:${key[pitch]}")
|
||||
- Inspired from korobeiniki.sh of the dsuni/bashtris repository
|
||||
- Supports two-note harmonies ("$duration:${key1[pitch1]},${key2[pitch2]}")
|
||||
- Supports every synth type included in SoX
|
||||
- Adheres to the Unix philosophy of "do one thing and do it well"
|
||||
|
||||
What this library doesn't support:
|
||||
|
||||
- Using your own samples (just use FamiTracker or a DAW for that)
|
||||
- Harmonies with more than two notes
|
||||
- POSIX compatibility

||||
