SwarSequencer

A sequencer that enables tonal improvisation over 163 Indian Sampurna Ragas

This is a work in progress and both the code and README will be updated with time.

Dependencies

• python2.7
• pyaudio

Usage

Clone this repository, ensure you have all dependencies and then run repl.py. This should start a custom python interpreter.

Setting up soundmodular Patcher.
Now interactively running SwarSequencer
>>>

Use get_raags() to obtain a list of available raags. Set raag to one from the list using set_raag() thus

>>> set_raag('Bhairav')
raag set to:  Bhairav
>>>

Use a raag from the list to play the basic aaroha and avaroha scale traversal.

>>> aaroha(3)
>>>

Should play the 3-note ascending figure from the Bhairav raag. Similarly,

>>> avaroha(4)
>>>

Should play the 4-note descending melodic figure.

To exit the interpreter, type exit()

This will terminate your session and export a testfile.wav in the root directory of your cloned repo.
