Randsik (random + musik) is a library for generating generative music in Python. In order to do this, this library relies on writing MIDI files to disk. These MIDI files can then be imported to a DAW software capable of working with them (e.g. Reaper, Ableton, Reason, Logic, etc.).
Installing randsik is easy with pip:
pip install randsik
The library itself relies on some data type primitives for constructing the musical patterns such as
randsik.Note, randsik.Rest and randsik.Pattern. These data types themselves wrap several data types provided by
the the Mido lirbary, including mido.MidiTrack,
mido.Message and mido.MidiFile.
In order to generate patterns, the randsik.generate function can be used. These function takes a number of
configuration parameters, but it also be called with no parameters to create something completely random.
Here are a couple examples of invoking this function:
import randsik
pat = randsik.generate(
note='D4', mode='dorian', octaves=2, measures=2, time_sig='3/4',
note_lengths=(randsik.QUARTER, randsik.EIGHTH)
)
pat.save('test.mid')The example above will create a two measure long pattern in 3/4 using quarter notes and eighth notes. The start note or tone, is "D4" and the musical mode is "dorian". When note and mode are left blank, they will be chosen randomly.
This is what it sounds like when played with a piano (click link to play audio):
Remember that the midi files you generate are random and will change every time.
The available notes span from C-1 to G9 (please be aware that some very high and lows notes reside outside of the audible range).
The available modes are as follows:
- chromatic (all notes)
- ionian
- dorian
- phrygian
- lydian
- mixolydian
- aeolian
- locrian
