Polyrhythmic MIDI Sequence Generator

So I heard you like polyrhythmic MIDI sequences? Well, now you can make your own without all that tedious clicking about in Ableton, and they will loop perfectly.

Features

Generate polyrhythmic MIDI sequences with customizable parameters
Create perfectly looping sequences
Adjust note pitches, durations, and gaps
Control the number of sweeps and slope aggressiveness
Automatically generate unique filenames with timestamps

Requirements

Python 3.x
midiutil library

Installation

Clone the repository (or just grab poly_MIDI.py):

git clone https://github.com/theeasyway/polyrhythmic.git

Install the required dependencies:
```
pip install midiutil
```

Usage

Open the poly_MIDI.py file in a text editor.
Modify the parameters in the script according to your preferences:

pitches: List of MIDI pitch values for the notes
sweeps: Number of sweeps in the sequence
base_note_gap: Gap between the notes at a given pitch
note_length: Duration of each note
slope_factor: Multiplier for the number of extra notes (affects slope aggressiveness)
start_offset: Start offset for the first pitch
start_offset_increase: Increase in start offset for each pitch pair

Save the changes to the script.
Run the script:
```
python poly_MIDI.py
```
The generated MIDI file will be saved in the same directory as the script, with a unique filename based on the current timestamp.

Example

See the /examples folder for .mid and .mp3 examples.

Additional Utility

The repository also includes a utility script note_to_pitch.py that converts musical note names to their corresponding MIDI pitches. This can be helpful when working with specific note sequences in your polyrhythmic MIDI sequences.
