## Multitrack exporter
---
## Despription
## Description
- Exports Patterns and projects individual Audio Tracks to seperate folders for use in your DAW
- Python cross plattform with single file binary for x86 linux
- Exports patterns and projects individual audio tracks to seperate folders for use in your DAW.
- Python cross plattform with single file binary for x86 linux.
## Installation
### Ubuntu 20.10 LTS (If the binary in /dist doesn't work)
`sudo apt install portaudio19-dev`
`sudo apt install python3-tk`
`pip install python-rtmidi`
`pip install pyaudio`
### Mac Install
`brew install portaudio`
`brew install python-tk`
`pip install python-rtmidi`
`pip install pyaudio`
`pip install mido`
`python3 underbridge.py` to start
### Linux binary
## Using Packaged single file Binarys _(The easy way)_
- Executables reside in the folder `/dist/`
- on Windows
`underbridge.exe`
- On Linux:
``./underbridge``
Underbridge_alt was packaged on a different system. Might help if you run into problems.

## Installation _(Less easy way)_
### Windows
- Install Python 3.9 if not already, 3.10 seems to cause problems.
- install portaudio_dev : `apt install portaudio19-dev`
- install mido : `pip install mido`
- install rt-midi: `pip isntall rt-midi`
- install pipwin: `pip install pipwin`
- install pyaudio `pipwin install pyaudio`
**Activate OP-Z device input in sound settings of windows and make it default**
- run `python underbridge.py`
### Mac Install - ( tested on Mac OS Monterey 12.3 )
install portaudio: `brew install portaudio`
install mido: `pip install mido`
install tk: `brew install python-tk`
install rt-midi: `pip install python-rtmidi`
install pyaudio: `pip install pyaudio`
**Set OP-Z device as input in sound of system preferences**
open terminal and type: `python3 underbridge.py` to start
### Ubuntu 20.10 LTS
- `sudo apt install portaudio19-dev`
- `sudo apt install python3-tk`
- `pip install python-rtmidi`
- `pip install pyaudio`
`python3 underbridge.py` to start
## Steps
- connect OP-Z via USB
- in /dist/ directory run ``./underbridge``
- Alternatively python3 underbridge.py in root directory. Make sure you have installed dependencies before..
- Run underbridge
